Edmunds' Expert Review

Overall rating

7.4 / 10

The 2018 Cadillac CT6 can best be described as a full-size luxury sedan, but it's priced like a midsize. If you like the idea of a spacious and upscale luxury sedan with a little Detroit attitude, this Cadillac fits the bill.

Under the hood, the CT6's segment-straddling identity is apparent. Turbocharged four-cylinder power is standard, and it's the same engine that's featured in the Cadillac's midsize CTS. You won't find that combination in any of its German competitors.

But there's no doubt that the CT6 reaches new heights of luxury relative to its midsize brethren. Throw in generous rear passenger accommodations, top-shelf interior trimmings and a competitive starting price, and the CT6 becomes a legitimate challenger to the traditional leaders.

2018 Cadillac CT6 configurations

The 2018 Cadillac CT6 is a large luxury sedan available in four main trim levels. The base CT6 is well equipped, while the Luxury trim adds high-end safety and convenience features. Next, the Premium Luxury adds even more technology, followed by the Platinum, which makes all options standard.

The base CT6 comes standard with a 2.0-liter four-cylinder turbo engine (265 hp, 295 lb-ft) and includes 18-inch wheels (19s with the V6), front and rear parking sensors, LED headlights and taillights, heated mirrors, a power tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, leather upholstery, eight-way power front seats (with two-way power lumbar), driver-seat memory settings and dual-zone automatic climate control. Also standard on the technology front are GM's OnStar system (with 4G LTE connectivity and Wi-Fi hotspot capability), Bluetooth, a 10.2-inch touchscreen with Cadillac's CUE interface, Apple CarPlay and Android Auto smartphone integration, a rearview camera, voice controls, four USB charge ports, wireless charging and an eight-speaker Bose sound system with satellite radio and three audio USB ports.

An optional Driver Awareness and Convenience package adds a panoramic sunroof, automatic high-beam headlights, automatic wipers, power-folding mirrors, heated front seats, a navigation system and an array of extra safety features (see Safety section for details). There's also an optional V6 engine rated at 335 hp and 284 lb-ft.

The Luxury trim starts with all of the above equipment and adds another engine choice, a 3.0-liter twin-turbo V6 (404 hp, 400 lb-ft), automatic parking system, auto brake hold (prevents forward/rearward creep when your foot is off the brake), a hands-free trunklid, four-way power lumbar for the front seats, front passenger-seat memory settings, a top-down 360-degree parking camera system, rear side window shades, upgraded interior lighting and a 10-speaker Bose surround-sound audio system.

The optional Comfort package adds ventilated front seats and heated rear seats. There is also an Enhanced Vision and Comfort package with those upgraded seats plus a unique rearview mirror that displays streaming video from a special rearview camera.

Moving up to the Premium Luxury gets you an upgraded gauge cluster display, a head-up display, and the Enhanced Vision and Comfort package as standard.

For both the Luxury and Premium Luxury trim levels, an available Rear Seat package bolsters the CT6 Luxury's feature list with a rear entertainment system and four-zone automatic climate control. An available Active Chassis package (not available with the 2.0-liter engine) bundles adaptive suspension dampers, active rear steering and 20-inch wheels. A 34-speaker (yes, 34) Bose Panaray premium audio system is also optional. For the Premium Luxury trim only, an optional Driver Assist package adds adaptive cruise control, a night vision camera system and enhanced safety-related automatic braking.

At the top of the totem pole is the Platinum, which adds all of the above as standard equipment plus 12-way power-adjustable front seats with massage functions, premium leather upholstery, and eight-way power-adjustable outboard rear seats with ventilation.

The Plug-In variant takes many of the options available in the Premium Luxury and Luxury configuration and makes them standard, along with a new 2.0-liter turbocharged hybrid powertrain (335 hp, 432 lb-ft). The Driver Awareness and Convenience and the Enhanced Vision and Comfort packages are all standard. The Hybrid comes with 18-inch wheels and is only available in rear-wheel drive. Due to the large battery pack, you do lose significant trunk volume.

Trim tested

The ratings in this review are based on our Full Test of the 2016 Cadillac CT6 Platinum (twin-turbo 3.0L V6 | 8-speed automatic | AWD).

NOTE: Since this test was conducted, the current 2018 Cadillac CT6 has received some revisions, including a new nine-speed automatic transmission for 2017 and the deletion of the Premier trim level. Our findings remain broadly applicable to this year's 2018 Cadillac CT6.


Formidable acceleration, powerful brakes and a smart transmission give the CT6 a king-of-the-road character that befits its flagship status.


The turbocharged V6 has strong pull from almost any rpm, and quick, smooth upshifts give the sense of virtually uninterrupted power. Zero to 60 mph takes 5.2 seconds, though, which puts this top-of-the-line CT6 midpack among top-shelf sedans.


The CT6's brake pedal is reassuringly firm and easy to modulate. Despite the car's roughly 4,400-pound bulk, the brakes hauled it down from 60 mph in just 102.4 feet in Edmunds testing, a stunning performance for a luxury sedan.


The steering effort gets artificially heavy in Sport mode without adding any tangible value for spirited driving. Left in its default mode, it's light and pleasantly accurate, if typically numb for the segment.


Body roll is held within reasonable bounds, but the CT6 feels large and long. Some cars shrink around you at speed; this isn't one of them. The CTS on which it's based is a great athlete, but the CT6 is unremarkable, like a stretched CTS on novocaine.


Throttle modulation is intuitive, but the transmission sometimes feels as if it has only two modes: "stay in current gear" or "redline ho!" An in-between step would be appropriate for a dignified luxury car.


The CT6 has potential in this category, but our test car's jittery ride held it back. Put the ride aside, and you've got a roomy, well-appointed sedan with a quiet cabin and massaging seats front and rear.

Seat comfort

The wide front seats don't offer much lateral support but are plenty comfortable on long hauls. Massage controls are finicky, but the multiple massage programs are addicting. The rear outboard seats feel first-class and offer massage functions of their own.

Ride comfort

Even on roads we know to be fairly smooth, our CT6 Platinum quivered uncomfortably. The ride was also a bit flinty over impacts, so we never really felt as if it was dialed in the way a car in this class should be.

Noise & vibration

The CT6's 3.0-liter V6 sends vibrations through the steering wheel at 4,500 rpm, which is common for a V6 but unwelcome at this price (e.g., Audi's V6 doesn't do it). The highway ride is hushed, with little wind, road or tire noise to speak of.

Climate control

Strong A/C performance and quiet fan. User-friendly touchscreen interface for climate controls with redundant controls below. Separate controls for rear passengers look like the redundant ones in front. Effective seat heating and cooling front and rear.


High-end materials are just about everywhere you look and touch, and the Platinum model we tested has every available feature. A good showing for the price, although customization options are limited.

Ease of use

Cadillac's infotainment interface has been improved since its introduction. The 10.2-inch touchscreen features large, easy-to-understand icons and a sensible menu structure. Other controls are mostly user-friendly as well, so it's an easy car to live with.

Getting in/getting out

Large doors afford wide openings all around, and the CT6's seats are at the perfect height to slide right in. Convenient and welcoming for all ages and stages.

Driving position

The CT6's power-adjustable wheel doesn't telescope out far enough, so it'll be a reach if you need to slide the seatback a ways. The wheel itself feels substantial in your hands, and gauge visibility is excellent. Up and down range for the seat is ample.


Tons of rearward travel for the front seats, and generous room in all other directions. Taller drivers have plenty of space. Rear-seat room is also ample, even for larger folks, but there are no footrests as in some competitors.


The view out is satisfactory front and rear. You don't feel as if you're peering out of a bunker. The streaming-video rearview mirror had us seeing double due to the different focal point, but it shows a wider view of what's behind (and can be turned off).


The CT6 Platinum's cabin is swathed in leather and chrome interior trim is thankfully sparse. Overall, the effect isn't quite as nice as what you get from Audi or Mercedes-Benz, but it's getting harder to pinpoint the flaws.


At heart, the CT6 is a stretched version of a midsize sedan (the CTS), and that shows in its relatively short and small trunk. Cadillac could also do a better job at providing interior storage options; the stylishness of the dashboard and center stack seem to have taken priority.

Small-item storage

The touchpad on the center console takes up some space that might otherwise be used for phone storage. You'll manage in the CT6, but your phone might end up in one of the cupholders. Decent room for other stuff under the center armrest.

Cargo space

The trunk has a wide opening that's great for loading large items such as golf bags. The trunk narrows abruptly at the rear wheelwells, however, and overall volume is modest at 15.3 cubic feet.

Child safety seat accommodation

The CT6's long rear doors and large back seat give it an inherent advantage compared to smaller sedans. A rear-facing child seat should fit with no need to adjust the position of the corresponding front seat. The two sets of LATCH anchors are easy to access.


Technology is a strong suit for the CT6, especially now that the user interface has been revised with a beautiful 10.2-inch display and quicker response times. If you're looking for high-tech features that are also user-friendly, the CT6 is a good pick.

Audio & navigation

Cadillac's CUE system has been improved. The touchscreen looks great and responds promptly to commands. The redundant touchpad between the seats provides odd haptic vibration feedback. Bose Panaray system sounds rich and full.

Smartphone integration

Apple CarPlay and Android Auto come standard on the CT6. Cadillac's got you covered with four USB charge ports, three USB audio ports and wireless charging to boot. Bluetooth phone pairing is quick and painless.

Driver aids

The CT6 Platinum comes standard with adaptive cruise control, forward collision mitigation, lane departure intervention, blind-spot monitoring, rear cross-traffic alert and a night vision system. There's also a streaming-video rearview mirror.

Voice control

Our repeated attempts to change iPhone playlists were unsuccessful even though we used the proper voice command structure ("Play playlist [name]"). Instead, a sustained press of the voice button accesses the iPhone's Siri voice commands, which work quite well.

2018 3.6 AWD
I haven't experienced the jerky transmission shift problems at low speed. Perhaps because I also turn off the auto stop/start function which is unrefined (very similar to our 2016 Audi A6 3.0T). The driving dynamics, technology and value have been as advertised. But fit and fitness needs work (loose rear quarter rubber seal, climate control panel popping out). At least my dealership experience has been excellent. The car lacks the blistering speed of our 2016 Audi A6 but just as buttery smooth (perhaps slightly more than that A6). And the hushed cabin, technology and the way this large car handles a twisty road, on the standard steel suspension, are rather impressive.
Best Full Size Luxury For the Money!
Tony Da'Acosta,07/07/2018
After hearing and reading all the stuff people where saying about the CT6 I decided to buy one. It wasn't easy since a lot of reviews where complaining about "vibrations felt on steering during acceleration" to "Suspension not being smooth enough all kinds of stuff, after finally getting one I can say most of those reviews where just hatting on the CT6. There is some vibration felt under extreme acceleration but to anyone that has owned an AWD vehicle if you say you have never felt this you are lying they all do it, before getting this CT6 I had a S550 AWD same feeling when picking up speed under hard acceleration, some reviews compared it to the junk Audi A6, had one of those junks too always at dealer for problems with vibrations, electrical stuff battery use to drain, trim on doors and pillars coming off, nav screen stopped working and weird noises from AWD system under hard accelerations and or turning at low speeds, after just 16mo. of ownership decided to take it to the nearest carmax and get rid of it, not to mention the trade value on the A6 was less than 45% after 16 mo. : (.. The Benz was a lot better than Audi very smooth and not as much vibration, the only problem was the electronic suspension other than that great car. I test drove the Lexus and I can't believe why people make such a big deal about that car, the LS 500 felt like driving a Ford Econoline felt very heavy and not mannered at all during lane changes, lots of tire noise at highway speeds and seats are not comfortable at all they are very hard rear are a little better but still for the price tag there is no comparing. Some websites say "the CT6 competition Offers more technology and options" well thats a lie, none of the ones I mentioned above had any of the options the Premium Luxury CT6 offers and even if you get the top of the line Lexus, Audi or Mercedes you still don't get the same technology you get with the CT6, Panaray Bose, Active Chassis and steering, wifi , night vision and not to mention Supercruise the best. There are a few flaws to the CT6 1. Engine should have more HP, even though it gets up and going very well . 2. Transmission on AWD model shifts hard at low speeds sometimes, not all the time but I do have a lead foot. 3. Start / Stop Technology is annoying I think Luxury cars shouldn't have this period or at least a setting where you can turn it off period never to come on again at next ignition cycle. Other than that there is nothing at the time that bothers me, fits all the stuff I have to carry for my 3 kids , car is very safe all of the safety and driver awareness stuff works great, Heads up display is great you see all the warnings there , auto parking feature is cool and works perfect, love the night vision and the 360 cameras record any disturbance to the car and records you trips. Great Car Overall and so far it's been great, Getting an average of 29.9 MPG but I mostly do highway.
After One Month - The Good The Bad and The Ugly
Bill Fisher,09/14/2018
My previous 4 cars have been in order Volkswagen Phaeton and a 2011 Hyundai Genesis, a 2013 Hyundai Genesis and a 2015 Hyundai Genesis. I have been driving my 3,6L Luxury Cadillac CT6 for 2,000 miles so far. My first driving impression is that for a large car, it drives much smaller. The steering is very precise and the car is definitely a point and shoot driver. To me that is a HUGE win. When cruising down the road it is quiet and silky. It's definitely the most serene car I've owned in my 65 years up until about 70 MPH. I think at higher speeds the Genesis G80 is quieter. This is my first Cadillac though because I've always despised floaty boat like drivers and that's how I always remember them. This is most definitely not that. Color me surprised. I actually test drove it when it was suggested by my favorite sales guy who moved from the Hyundai store to a Cadillac store. I fully intended on buying a Genesis G80 Sport and was waiting for one to arrive in a color I liked. (it never did) Hyundai needs to fix that. It lost a sale over the fact that a vehicle in anything other than gray or black was never available. But when I drove the Cadillac I fell in love with the ride. My hot buttons are Safety, Quiet and Handling. I will not stand for a car that wallows. The Cadillac checked all the boxes. I have had this, as I said, for one month and now comes the ugly. The car has been to the dealer more in one month than my three Genesis' combined did over 8 years. The initial quality problems, while not big issues shouldn't happen and I will list them. 1.) The console cover once fell right off in my hands when opening it. It was replaced under warranty. The fact is, it is the smallest center console I ever saw besides. It's almost a joke. Not a deal killer for sure but all the same. 2.) The right front wheel had a big gouge in it. It was replaced but I had to go back to the dealer a 2nd time because the air pressure monitor stopped working in that wheel after replacing it. 3.) When the car goes into 4 cylinder mode there is a vibration that seems like either the timing is off a little or their is a torque converter shudder. It is almost imperceptible. But I feel it. On the plus side, it doesn't go into 4 cylinder mode often. I find it hard to believe that Cadillac engineers designed it to drive that rough in 4 cylinder mode. My dealer doesn't feel its out of spec. 4.) The drivers seat is squeaking. It normally doesn't start until I have a few miles in and the car is warmer but it is getting increasingly bad. If I bounce my butt up and down I can make it sound like a cheap motel bed. When driving it is apparent when I hit a bump or corner. This just bugs the crap out of me and I am going to end up getting it fixed or shoot the car. I also think the dealer prep was lazy. I had to have them work on both my windshield and side view mirrors because of some kind of residue that made my windshield look sandblasted and the side view mirrors smudged and dirty looking. I tried resolving these myself with window cleaner and scrubbing to no avail. I don't know what they used but it's mostly OK now. I will say, once these issues are taken care of I will absolutely LOVE the car. But these niggling issues should not exist on a $65,000 car. That said, I love the drive, the quiet and the value. Would I buy it again? At this price point you aren't going to get another car that offers the quiet, size, the comfort and the safety, combined with the precision steering on anything like this. In short, if I don't buy a Genesis G80 Sport, my next option would be this. For reference, I test drove Acura, Audi (I own an A5 Cabriolet) Volvo, Genesis G80 Sport, Kia Stinger (wife vetoed that one) Buick Regal Wagon and Honda Accord. The Genesis does fall a little short on the Interior materials compared to the Cadillac. But the Genesis has a better infotainment system and real knobs for the radio and A/C controls. I'll call it a toss-up at this point. But if the Genesis had just a bit better interior it would have won out. UPDATE: More time has passed and I think it's time to say it like it is, I'm sorry I made the purchase. Very sorry. Here's my beef with this car. Any time it goes into 4 cylinder mode it virtually rumbles. HORRIBLE! The dealer says it's normal. I call BS. Second, and I'm sure they will fix it. Or at least I hope they will, the drivers seat squeaks worse and worse the longer I own it. How in the heck do they validate seats that squeak like these do? The infotainment system needs tweaking. The lack of buttons means there are always, and I mean always, going to be fingerprints all over that big beautiful 10 inch screen. Now these things may seem small to you, but when you are the owner and driving it, they matter. Especially the seats and the rumble. I'm sorry I made this purchase. I regret it. I should have bought a Genesis G80 Sport.
Perfect Purchase
Ken Deill,10/12/2018
I have not been this excited about one of My Cadillacs since my first Northstar purchase in the late 1990s. I usually purchase used Cadillacs. I have had a 1976 Seville, 1997 SLS, 2000 STS, 2003 STS, 2007 STS AWD, 2013 XTS platinum. Most purchased three years old with low mileage. I now decided because of the Super Cruise feature to purchase New. I located the color, and model I wanted , drove 112 miles one way, and bought the White over Black CT6 platinum, I now own. I purchased it after a drive around the block. I traded my 2013 XTS platinum in, received 0% five year money, and drove home. 55 miles of which I went hands free, on super cruise. I have had Adaptive cruise for some time now, so I was used to everything, except letting go of the wheel. It was fantastic. The V-6 TT is right there as well. I have 1960s muscle cars that cannot beat it. I decided to drive the CT6 to my home in Louisiana 938 miles away from my usual residence. My wife, and I drove 600 miles the first day 85% of which was hands free. The whole round trip I drove hands free 1600 miles, Best 33 miles to a gallon, average 28. Through St louis in driving rain, and all. My wife said it beat every other Cadillac for front seat comfort. Finally the best massage in town on all four seats. I have peole at work that go out at lunch time just for that experience. The stereos have been so good for so long it is difficult to say, however the 34 speaker system , we love it as well. We both look very forward to the upcoming V-8 , I will opt for the 500 horse unit as I like the looks of that vehicle better. Thanks Cadillac for another great experience every time I decide to take this car. Did I forget to mention , It is fun again to take an automobile trip. Fun to drive 80 miles or so for dinner. Thanks Again. Ken Deill

2018 Cadillac CT6 video

JASON KAVANAGH: Hey, everyone. Dan and Jay here, and welcome to our latest comparison video featuring Cadillac Super Cruise versus Tesla Autopilot. DAN EDMUNDS: What you're about to see was shot in February. Since then, Tesla has updated its Autopilot software, and we've been out to retest it. JASON KAVANAGH: Now, there's a separate video that addresses the updated software. And there's a link to it at the end of this video. So make sure to check that out. DAN EDMUNDS: A lot of people are excited by the prospect of autonomous vehicles and self-driving cars. And just about everyone has heard of Tesla's Autopilot. But it's not the only game in town, because Cadillac has just introduced Super Cruise. JASON KAVANAGH: So we rounded up our long-term Tesla Model 3, which is equipped with Autopilot, and a Cadillac CT6, which has the Super Cruise system. We're not comparing the cars here. This is strictly a comparison of the two systems. We're going to take these two vehicles out into the real world to see what these systems are made of. DAN EDMUNDS: So I'm driving a Cadillac CT6 sedan. And it's pretty nice. One of the things that this car has is something that they call Super Cruise, which is pretty much a super cruise control. Right now, the car is managing the speed that we're driving by managing the gap to the car ahead. That's adaptive cruise control. This has the ability also to steer the car in an auto-steer mode indefinitely, so long as certain conditions are met. The road has to be surveyed. In other words, the car needs to know that this is limited-access freeway. It doesn't have any kind of intersections or any possibility of a car turning in front of us. If you go to the Super Cruise website, you'll see a map of the United States and it has which interstate highways are part of the Super Cruise network. And it also needs to know that I'm looking straight ahead and I'm engaged in the task of driving. And it does that by using a sensor here and two sensors here in the wheel. I saw the little gray steering wheel appear for a moment. There it is again. Press the button. And here we go. We're in hands-free mode. This is a real hands-free system because this system is looking at where my head is pointed and where my eyes are pointed. So if I look over here to the camera too long, eventually it's going to get mad at me and this will start to blink, and it will be my indication that hey, there it goes. The system has it pretty well under control, but this is not autonomy. This is another step closer to autonomy, but we're not there yet, because it still needs me to monitor the situation. JASON KAVANAGH: I'm driving our long-term Tesla Model 3 and one of the options that we made sure to select is Autopilot. And Autopilot is Tesla's semi-autonomous driving mode. It's not a self-driving mode. It's really an adaptive cruise control system with a very sophisticated lane-keeping system working in conjunction with it. There are a variety of sensors and cameras on the outside of the car that are monitoring not only the lane markings, but also traffic around the vehicle in order for it to get its bearings on where it is on the road. You turn on Autopilot pretty simply. You tap this lever twice and boom, we're in Autopilot. And I can take my hands off the wheel for a brief amount of time. Eventually, it'll start to make angry noises and is telling me to put my hands back on the wheel. And if you don't put your hands back on the wheel, it will cancel Autopilot for the duration of that drive. So you want to make sure you put your hands back on the wheel. Autopilot is engaged and active when you have this blue steering wheel icon illuminated. When that's not illuminated, you're basically either just driving or it's adaptive cruise only. And it's showing you on the screen these blue lines are showing that it sees the lane markings. It's got these waves on the side of the car when you're near another car in an adjacent lane, and then it's got vehicles in front on the screen when you've got vehicles directly in front of the car you're driving. So right there, it lost one on the lane markings and wandered to the edge of the lane. So I intervened in order to put it back in the lane. So it's not a perfect system. As the driver, you still have to pay attention to what's going on. It's, again, not a self-driving mode. DAN EDMUNDS: So we're in morning commute traffic here in Santa Monica on the west side, and it's pretty notorious. And I'm going 16 miles an hour, and I'm doing it hands-free, so long as I'm looking straight ahead. And that's key, because if I'm not looking straight ahead and something happens, there won't be time for me to react. But because I'm looking straight ahead, I probably will naturally put my hands on the wheel and reengage before the system even tells me to, because my Spidey Sense is always off. JASON KAVANAGH: In traffic, Autopilot is really in its element. It's got enough information from the surrounding vehicles that it knows its place and it can deal quite well. Coming up in the carpool lane a little later is a K-rail that's pretty close to the edge of the lane, so we're going to see how well it deals with that. Going to have a light touch on the wheel here. Had no trouble with that at all. DAN EDMUNDS: You know, carpool lanes can be narrower than normal lanes, and they can be really close to the concrete center divider, as you can see this one is. But I am approaching a freeway intersection. It knows that I'm going to go straight and not exit the freeway. No, it doesn't seem to know that. It's telling me to take control. And had a red indicator came on, basically saying, hey, I need you to be engaged. But you know what? It just came back on. So that was an artifact. I think what happens is whenever the computer gets confused-- I got passed by an SUV. That SUV looked like maybe it was going to come in front of me. Maybe the computer wasn't sure. And so it said hey, put your hands back on the wheel. JASON KAVANAGH: So Autopilot's got a little bit of a idiosyncrasy where it wants your hands on the wheel in order for Autopilot to remain active, but you can't put too much pressure on or it thinks that you want to take over the task of driving. So it's a little bit of a balancing act to get accustomed to how much pressure to put on the steering wheel, but it's not too hard. One of the features it has is an automatic lane change. I can just put the blinker on and it changes lanes automatically without any intervention from the driver. It's a pretty neat trick. DAN EDMUNDS: This doesn't have the lane change feature that a Tesla has. They're not willing to go quite that far. They would like the driver to be the one who initiates and executes a lane change. So I'm going to put on my turn signal. Now when I change lanes, this is going to turn blue, which means auto steer is in pause. And as soon as I get centered, it's going to turn green. It's not there yet. There it is. And now I can go back into this mode. 65-70 miles an hour. And there's some corners, and no problem. You know, freeway corners have a big radius. This system only really works on the freeway, so no problem coping. JASON KAVANAGH: Now, we're on a divided freeway right now, and this is kind of the ideal environment to use Autopilot. And the reason is because it throws the fewest variables at the car. In other words, you don't have to deal with stop signs or traffic signals, which auto pilot can't deal with. It also has traffic going in only one direction with the divider, so that makes things easier for the system as well. So it's just trying to take us off the freeway onto a different freeway, so I had to intervene right there. So we're going to see how this system deals with the loss of a lane. We've got a lane merge coming up right here. Our lane is going away. And it seems to be OK. It handled the loss of a lane with no problem whatsoever. DAN EDMUNDS: So just a minute ago the red light flashed and I was asked to put my hands back on the wheel. And at first, I didn't understand why, and then I came onto this construction zone. They've got k rail up here. These two lanes are dug up. So obviously, they know that this section is under construction and they're not allowing Super Cruise to work in the construction area. So we've seen what happens when I look away or when I turn my head. And I'm wearing glasses. But what if I was wearing sunglasses? Well, we can try that out. It can see that I am looking where I need to be looking. If I turn my head to the side, it's going to warn me to look ahead, and there it goes. But I don't know if it's going to be able to pick up the side eye. If I glance away underneath my glasses, will it pick up that? Oh, it did. It's a pretty powerful system. It's got pretty high confidence that it knows what the driver is looking at. JASON KAVANAGH: Autopilot is trying the center the car in the lane, and you can tell that it's constantly trying to find the edges of the lane with its sensors and cameras, because there's a slight weaving effect here. We're sort of caroming gently in the middle of the lane. Autopilot has no restrictions on where it can be used. In other words, you can enable Autopilot on a limited-access freeway like we're on currently. You can have it active on a side street. Basically anywhere the lane markings are clearly defined and it has a reference, Autopilot will work. So while that's true, it's a system that you should really use primarily on the freeway, like on a long road trip, just because of some of the limitations of the system on a side street environment. DAN EDMUNDS: Right now, the system isn't seeing the lane lines, and it's not reengaging. And that's because we're on a concrete freeway that's been bleached out by the sun. The city here has put black strips, so it's almost like this particular road has black lane stripes. And the system had a little bit of a hard time making sense of that. But now that it has, I'm back in Super Cruise mode. It's just a sign that this system is conservative. It's trying to make the safest decision possible and not just go off and calling it good enough. JASON KAVANAGH: Now in this two-lane road here, we're approaching an intersection now. It's a green light. Certainly, it's not going to stop for red lights, but we're green. It's looking for the lane markings, and Autopilot took it in stride. No issues at all. As long as it's got consistent lane markings, it's just fine. Once it loses the lane markings, then things are getting a little curveball. DAN EDMUNDS: Yeah, interesting thing about Super Cruise is it's pretty relaxing. The ability to take your hands off the wheel and just kind of chill but be ready. I think that reduces the workload just a little bit, which might make that kind of travel more enjoyable. But certainly here, there's no anxiety involved in using this. It's quite the opposite. JASON KAVANAGH: Yeah. So when the lane gets really wide like that, sometimes it sort of dives toward the middle of the lane to try and find the lane markings on the opposite side. And once it finds them, it cuts across again to the other side. So this is where Autopilot seems to be performing the worst is on this two-lane road of gently rolling hills. Every other circumstance we've thrown at it, it's been much better. And this is not good at all. Wow. So it just crossed the double yellow. I would get pulled over if I drove the way the Autopilot's driving right now. I'm not letting it do that. So we had a truck coming head-on, and I didn't want to take any chances with Autopilot going over the double yellow again, so I just intervened right there. So Dan, one of the things I learned about using Autopilot is that while it allows you to use it anywhere at any time, it's really kind of better suited for freeway use than it is for side street use. DAN EDMUNDS: Yeah. And that's the thing about Super Cruise. You don't have that choice to make, because it only works on freeways that General Motors has blessed. And they also have sensors in the car that look at my face and eyes to make sure that they're looking straight ahead and I'm fully engaged. And the payoff for all of that is true hands-free capability. JASON KAVANAGH: Yeah, that's one thing about Autopilot is that it requires the drivers hands to be on the wheel, and that's sort of a pro and a con because it's more incumbent upon the driver to determine when it's safe to use the system and when maybe they don't want to. DAN EDMUNDS: Yeah, and I think that's why I frankly trust this one more. JASON KAVANAGH: For more information on Teslas, Cadillacs, and everything else, go to Edmunds.com.

Tesla Autopilot vs. Cadillac Super Cruise | Comparison Test

Tesla's Autopilot and Cadillac's Super Cruise are the most capable driver assistance systems available and provide a glimpse toward the future of self-driving cars. These semi-autonomous driving modes aren't the same, though. And while Tesla's Autopilot has been deployed on the Model S, Model X and Model 3, Super Cruise debuted this year and is available only on the Cadillac CT6. We drove an Autopilot-equipped Tesla Model 3 and a Super Cruise-equipped Cadillac CT6 to explore the system's similarities and differences in the real world.

More about the 2018 Cadillac CT6

The 2018 Cadillac CT6 is built to be a big leap forward for GM's most prestigious product. It's a bold statement that announces to the world that Cadillac is among the world's heavy hitters in the luxury game and that it plays on the same plateau as Audi, BMW and Mercedes.

But it's also a value proposition. It's priced closer to smaller, midsize luxury cars, but it's got all the equipment and poise of a true flagship — without compromising driving dynamics or efficiency. This is Cadillac's bold statement that Detroit will fearlessly take on Ingolstadt, Munich and Stuttgart.

Built around a stretched and fortified version of the smaller CTS chassis, the engine in the CT6 is mounted longitudinally in front sending power to the rear wheels. Yes, all-wheel drive is an option. But buyers won't be stuck with front-wheel drive if they decide they only need two driven wheels.

The standard powerplant in the CT6 is a 265-horsepower, direct-injected and turbocharged 2.0-liter four-cylinder. A step up is a 3.6-liter V6 with 335 hp. The performance option is a twin-turbocharged 3.0-liter V6 knocking out 404 hp.

Don't let what the CT6 has in common with the CTS distract from appreciating what makes it distinct and compelling. Though it weighs practically the same as the CTS, its wheelbase stretches 8.5 inches longer. That relatively light weight means the CT6 will hurry down a test track at about the same rapid pace as the CTS. And that 8.5 inches translates into generous rear legroom in a cabin tastefully trimmed in premium materials. This car feels like a thoroughbred, not a compromise.

The CT6 is available in four trim levels: base, Luxury, Premium Luxury and Platinum. The trims and a variety of optional packages bring safety, comfort, performance and entertainment features to the CT6.

The EPA fuel economy ratings prove out the obvious: The CT6 with the best performance is a rear-driver equipped with the 2.0-liter turbocharged four-cylinder engine. It delivers an EPA rating of 25 mpg combined (22 city/30 highway). The thirstiest CT6 is an all-wheel-drive machine running the 3.0-liter twin-turbo V6. It gets 21 mpg combined (18 city/26 highway).

This is Cadillac's most fully realized sedan in decades — it needs to be to take on some of the world's best cars. Take time to consider the dozens of alternatives and use Edmunds to find the CT6 that will fit your needs.

Should I lease or buy a 2018 Cadillac CT6?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
