Which 911 does Edmunds recommend?

While the 911 is a consistently brilliant car all the way up to the range-topping Turbo S, the fundamental goodness of the base Carrera model is often underappreciated. We'd go with a Carrera coupe with few options. Purists will want the outstanding manual gearbox, but the PDK dual-clutch automatic transmission is exceptional, too. The Premium Package with power sport seats is a great value, and we'd add Sport Chrono and the front axle lift system.

Edmunds' Expert Review

Overall rating

8.4 / 10

Few cars match the 911's poise in so many areas. The 911 range is at once fast yet tremendously composed, rewarding and civilized. Likewise, there are few cars that are offered in such an onslaught of variants — for 2018, there are 20 distinct 911s. Porsche's strategy of methodically rolling out a new variant nearly every six months (or so it seems) has been so successful that it has been adopted in varying degrees by many other automakers.

The 911 shares its front-end architecture with the lesser 718 Boxster/Cayman models, which reduces cost — the bones from the firewall forward are largely shared. Aft of the firewall, the 911 is like no other car. Its 2+2 seating arrangement and engine hung outside of the rear axle are unique in the motoring world.

While in the past the 911's rear engine layout has been at the root of some wayward handling characteristics, there is no denying the braking and acceleration benefits that it imparts. And the modern 911 has thoroughly exorcised its more notorious habits. In the process the 911 has morphed into more of a GT car, something that is larger and more comfortable for long journeys than 911s of yore. Yet there is no denying it is an accomplished driver's car with few equals.

2018 Porsche 911 configurations

The 2018 Porsche 911 is available in a breathtaking number of trim levels and body styles. At its most basic level, there's the standard rear-wheel-drive Carrera coupe or the open-top Cabriolet. Each of those models is available with all-wheel drive, which is designated as the Carrera 4 or Carrera 4 Cabriolet. There's also a Targa model with a retractable hardtop that is only available with all-wheel drive. All of the aforementioned models are also available in a higher-performance S version. There's also an even higher-performance Carrera GTS that is available on all three body styles. The most powerful rear-wheel-drive model is the track-ready GT3. Finally, there's the all-wheel-drive 911 Turbo. It, too, is available as a coupe or convertible in either standard tune or more powerful S tune. If that's not enough, the Porsche Exclusive program provides for further customization.

Carrera models are rear-wheel-drive coupes and are equipped with a 3.0-liter twin-turbo flat-six engine (370 hp, 331 lb-ft). A seven-speed manual gearbox is standard; the PDK dual-clutch automatic is optional. Don't be fooled by its "base" billing — the Carrera is one hell of a satisfying car that is often overlooked.

Carrera 4 models (and others with the numeral 4 in their names) add all-wheel drive and 1.7-inch-wider rear fenders.

All S models (aside from the Turbo S) have a twin-turbo 3.0-liter flat-six engine with more power (420 hp, 368 lb-ft), larger brakes, a limited-slip differential and 20-inch wheels. Optional features on S models that are unavailable on the base versions include a sport suspension, active stabilizer bars and rear-wheel steering system.

Cabriolet models are equipped an electrically operated folding soft top, while Targa variants have an electrically stowable hard roof panel.

GTS variants are essentially S models with more standard equipment, a power increase (450 hp, 405 lb-ft), the wider rear fenders of 4 models on all GTS variants, and unique interior and exterior trim. These models are deceptively desirable.

Turbo models are mega-powerful cars with an immense range of talents. They have a 3.8-liter twin-turbo flat-six engine (540 hp, 486 lb-ft) and rear fenders that are 2.8 inches wider than the base 911's, and are equipped exclusively with a PDK gearbox and all-wheel drive. Turbo S models have more power (580 hp, 516 lb-ft), center-lock wheels, active stabilizer bars, carbon-ceramic brakes, 18-way adaptive sport seats with backrests in leather, a two-tone leather interior and adaptive LED headlights as standard equipment.

GT3 models are the most focused of all 911s and are favored heavily by the trackday contingent of owners. They are exclusively rear-wheel-drive coupes that have a nonturbocharged 4.0-liter flat-six engine (500 hp, 339 lb-ft) and a choice of seven-speed PDK or a unique six-speed manual gearbox. A fixed rear wing and unique front end and underbody treatments enhance its aerodynamic performance. Rear-wheel steering, active engine mounts, a mechanical limited-slip (PDK-equipped GT3s have an active differential), unique seats, navigation and a track analysis app are standard.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our Full Test of the 2017 Porsche 911 Carrera S (turbo 3.0L flat-6 | 7-speed dual-clutch automatic | RWD).

NOTE: Since this test was conducted, the current 911 has received only minor revisions. Our findings remain broadly applicable to this year's 911.


The competence of the Carrera S spans a vast range. It expertly balances power and high-speed performance with in-town drivability and everyday use. The dual-clutch automatic gearbox is a benchmark, and its acceleration from any speed is seamless. You have to look for turbo lag to find it.


In Edmunds track testing, the Carrera S was blisteringly fast, going from zero to 60 in just 3.4 seconds, reaching the quarter-mile marker in 11.4 seconds at 121 mph. Part-throttle acceleration is impressively robust, too. Few drivers will complain about turbo lag, such is its responsive nature.


Firm pedal with lots of braking power when you're really moving but the brakes' sensitivity may require some drivers to adapt their braking style. Our simulated panic stop at the track from 60 mph measured an eye-watering 96 feet. Only a few cars on the road today can stop shorter.


The steering is well weighted everywhere. Rear steer helps with parking and low-speed maneuvers while high-speed directional changes are light and responsive. There's a bit of a disconnect from driver to front-end action, too, but nothing with modern power steering feels better.


Midcorner bumps don't faze the Carrera S, and the speed with which you can enter a corner makes you feel pretty heroic, even though the car is doing the work. The Carrera S' limits are extremely high (it averaged 1.01g on our skidpad) and it exhibits virtually zero body roll.


The seven-speed PDK transmission works its magic in almost every scenario. It's excellent on long uphill grades while also super intuitive on curvy back roads. Automatic and manual mode are equally enjoyable. It's about as drivable as you'll find while getting this kind of epic performance.


The standard-bearer of comfort among sports cars. Great seats, a firm but forgiving ride and plenty of creature comforts. Road noise with the optional wheels and tires is the sole black mark.

Seat comfort

The optional 18-way sport seats' substantial side bolsters provide ample lateral support but don't get in the way of terrific long-distance comfort. A multitude of adjustments will suit even the most finicky driver.

Ride comfort

Firm, but won't beat you up on a long trip. Optional adjustable dampers provide a good breadth of firmness. Bumps and ruts are short-lived and extremely well damped.

Noise & vibration

It's a relatively quiet ride in the city, but at elevated freeway speeds the optional Sport exhaust is audible and there's a constant hum from the high-performance summer tires. We suspect the standard wheels and tires are less aggressive in this regard.

Climate control

Air-conditioning blows super cold and acts fast. The cabin gets very comfortable very quickly, even on hot days. The optional cooled/heated seats operate instantaneously and effectively. Small, complicated, hard-to-find climate controls hurt its score in this category.


Loads of headroom and good forward visibility. Materials quality and driving position are excellent. Though the backseats are small, not many competitors even offer them. Limited rear visibility and a backup camera that isn't great.

Ease of use

The controls are well within reach. The drive mode knob on the steering wheel works especially well. Too many small buttons that don't all work the way you'd expect.

Getting in/getting out

Despite the low roof and somewhat high stepover, it's no more difficult than any other sports car to get into or out of. Our tester, equipped with the optional PASM Sport suspension, sits nearly an inch lower than standard.

Driving position

Solid fundamentals of control placement are abetted by a huge range of adjustment in the optional 18-way adjustable front seats and power tilt-and-telescope steering column. There's nothing in your (and your perfect driving position's) way.


Front headroom and legroom are abundant, but wider passengers may feel the pinch. The backseat is best for luggage; even small children will be cramped. Our sunroof-less test car easily fits long-of-torso 6-foot-plus drivers.


The low, sloping hood and large windshield contribute to excellent forward visibility. Relatively large rear roof pillar blocks your view of the Porsche's small blind spot. Small mirrors and a small rear window. Excellent parking sensors; the backup camera is acceptable.


After two weeks in the Carrera S, we were only able to find one fault in build quality: a clunky plastic knob for the drive mode selector on the steering wheel. Practically everything else is flawless. Excellent materials, tight tolerances and everything you'd expect for the price.


The Carrera S is pretty practical for a sports car. Beyond the front trunk, the rear seat has a fold-down luggage shelf that's quite useful. The cabin has smart small-item storage solutions.

Small-item storage

Small-item storage is limited but somewhat smart. The cupholders stow unobtrusively in the dashboard (but they're still tiny), the center console isn't very deep but easily swallows a large smartphone and a wallet, and the door pockets are long but shallow.

Cargo space

While its 9.1-cubic-foot trunk seems small compared to those of rivals, the 911 has a folding rear seat that acts as a large luggage shelf. Combine the two and you've got plenty of space for gear. Most rivals have only two seats.

Child safety seat accommodation

Under a small velcro-attached patch on the rear seats are two easily accessible lower LATCH points. There's one top anchor on each rear seat. Big child seats just won't fit back there. Even medium-size ones will have a problem. Even so, several rivals are missing a backseat altogether.


While an improvement on previous systems, the current Porsche tech interface isn't the most user-friendly on the market. Device integration and voice controls had a few hiccups during our test. Get past those quirks, though, and the system can do all of the basic tasks you'd expect.

Audio & navigation

The eight-speaker system is relatively bass-heavy. A 12-speaker Burmester system is optional. The nav screen is lower than preferred, though its pinch-to-zoom feature is excellent and entering destinations is simple.

Smartphone integration

Apple CarPlay is standard, which works relatively well once you get it connected but may take a few attempts. The native music system is easy to understand, but it doesn't index music quickly and it doesn't always obey commands.

Voice control

Underwhelming voice control. It had a difficult time responding to basic commands, and its menu structure has a steep learning curve. If you've got Siri at your disposal, use that feature instead — it's much more responsive.

2018 Porsche 911 video

[MUSIC PLAYING] CARLOS LAGO: That's a 2019 Chevrolet Corvette ZR1. ALISTAIR WEAVER: And that's the 2018 Porsche 911 GT3. CARLOS LAGO: Now, those three digit alphanumeric codes mean a lot. In the Corvettes case, ZR1 means it's the highest performing and most powerful version of the Corvette you can get, with 755 horsepower, and an optional track package that gives it a big rear wing, and sticky race track oriented tires. ALISTAIR WEAVER: Which makes it a perfect match for the GT3, named after sports car racing class. It was developed by Porsche's track motor sport division. And it's built on the same production line as the 911 race cars. Oh, and it revs to 9,000. CARLOS LAGO: You may be thinking, why didn't we go with the GT2RS. And while it's more of a performance equal to the ZR1 when it comes to horsepower, it costs nearly $300,000, or more than double the price of that car right there. ALISTAIR WEAVER: On your shopping list, the GT3 and the ZR1 are the real rivals. In many ways, it's a classic battle. It's a American bang for buck versus European culture and sophistication. CARLOS LAGO: What we're interested in is how these two super sports cars handle for your typical enthusiast on the road and at a racetrack. ALISTAIR WEAVER: So we are going to put them through the full Edmund's instrumented test. Then we're going to do a few laps. CARLOS LAGO: But before we do that, be sure to subscribe to our YouTube channel and visit edmunds.com for all your car shopping needs. [MUSIC PLAYING] One of the Corvettes primary strengths has always been the value. Not only does this particular ZR1 cost $30,000 less than that GT3, it has more. More tire, more power, more torque, even a bigger rear wing. There's actually one more gear and it's optional automatic transmission. But the real highlight of this car when you see it for the first time is the fact that its supercharged V8 engine is so big, they had to cut a hole in the hood so it can fit. Fantastic. ALISTAIR WEAVER: Allow me to be big geekish for a moment. This generation of the 911 is code named 991. And this is actually Porsche's second attempt to the GT3 version of this car. The first one was fitted with a 3.8 liter engine, which to be honest, proved a bit troublesome. But this new one has a 4 liter that's been comprehensively redesigned. It's of course, larger than before, but hey, at least it still fits. This is basically a race car engine. So there's no supercharger. No turbocharger. Just a purity of purpose and instantaneous throttle response. Some of the detailing on this car is just fabulous. I love this carbon fiber engine cover. And just check out this little hinge for lowering the hood. Unlike the Corvette, you don't have to pay extra for a giant rear wing, which has now been redesigned to offer more downforce. You do, though, have to shell out an extra $9,000 for some carbon ceramic brakes, which is standard on the ZR1. And these fabulous carbon bucket seats, they're an extra $5,000 grand. Porsche hasn't lost its taste for over priced options. [MUSIC PLAYING] CARLOS LAGO: Despite the 255 horsepower difference between these two cars, they both reached a quarter mile an 11.2 seconds. With all that power, the ZR1 has a harder time leading the line, taking 3.3 seconds to reach 60. And that's including a one foot rollout. The GT3's launch control manages the grip more effectively, getting the car to 60 in 3.1 seconds. Both cars have large carbon ceramic brakes and sticky Michelin Pilot Sport Cup 2 tires, delivering short consistent stopping distances. ALISTAIR WEAVER: The 911's rear weight buyer should mean better braking, but not in this pairing. It took the GT3 103 feet to stop from 60 miles an hour. A still excellent result, but the ZR1 did it in just 95 feet. Extraordinary. CARLOS LAGO: Much like the acceleration results, our 200 foot skid pad presents another role reversal. While the GT3 averaged 1.18g, a normally incredible result, the ZR1 put down a staggering 1.24g average. That's a result unheard of in a street car. ALISTAIR WEAVER: Having crunched the numbers, we headed to the streets of Willow Circuit in Southern California for some high speed lappery. CARLOS LAGO: We thought about hiring a pro racing driver and bolting them into these cars and seeing how fast they could go when it comes to lap times, but then realized, what do you actually learn by doing? ALISTAIR WEAVER: If you want to find out, frankly Google it. Both of us have been testing cars a long time. Me slightly longer than him. We spent a lot of time on racetracks in different cars. So this is about what these cars mean to you. If you're going to buy the GT3 or the ZR1, will it feel to you on a track day? CARLOS LAGO: Let's find out. ALISTAIR WEAVER: Let's find out. [MUSIC PLAYING] Do you know how bad a passenger I am? CARLOS LAGO: About to find out, I bet. ALISTAIR WEAVER: Geez. CARLOS LAGO: So Corvette ZR1 approaching 109 miles an hour. We'll slowdown. ALISTAIR WEAVER: Look at the tires. CARLOS LAGO: What we really got to talk about what this thing is the overall experience in the engine. This is such a dominating factor of this car. Big is 6.2 liter V8. 755 horsepower. And my god, just listen to that. Spectacular, isn't it? ALISTAIR WEAVER: It is spectacular. Well, I guarantee this, if you take a passenger who has never been in a fast car, this car will terrify them. CARLOS LAGO: Might terrify the driver too. ALISTAIR WEAVER: Yeah, it will. CARLOS LAGO: This is a car, frankly, that starts as a $50,000, $60,000 dollar, you know, GT sort of sports car. And to see it be at this level of performance is astounding. So this is the optional bucket seat. ALISTAIR WEAVER: No. CARLOS LAGO: Yes. ALISTAIR WEAVER: That's not even a bucket. CARLOS LAGO: It's a very wide mouth bucket. And I find that, yeah, it's more comfortable on the road than the GT3. But on the track, I'm bracing against the driver door with my knee. ALISTAIR WEAVER: If you like, my biggest single problem with this car is the driving position. I'm just not comfortable. I'm moving around too much. And in something that's this fast that r requires this much concentration, if you're not properly located in the car, then you can't drive it properly. The physicality of the car, it feels heavy. You can't see the corner. You peer out of these little tiny slot of a windscreen. CARLOS LAGO: This is almost like an advanced level driving experience because the steering requires so much effort, because you have so much mass. You can sense it all around you. This isn't that much heavier than the GT3, but it feels like it. ALISTAIR WEAVER: And in this car, you kind of feel like the electronics are constantly doing battle with the physics, whereas in the 911, you'll live up to that. You actually feel the electronics here are an aid. They're guiding you through the process. CARLOS LAGO: And there are a lot of electronics in this car. We have a very adaptive, very advanced stability control system. We've got electronic dip. We've got a sensor that's looking at the tire temperature as well as the pressure. There's a lot happening underneath here. A little bit more cognisant of it in this car than you are on the GT3. ALISTAIR WEAVER: You've also just gotta be aware how fast this thing is. You are arrive at corners 20 miles an hour faster than you think. When I jumped into it live on corner one, you got a massive dose of oversteer just because the tires were cold. And you've got 755 horsepower. 80 miles and hour. Nice staying under it. Oh. Well, Alistair Weaver's last will and testament. CARLOS LAGO: That's a riot, isn't it though? ALISTAIR WEAVER: Oh, yes. Bury everybody. It's great. I don't wish to patronize you, but this car could not be more American. CARLOS LAGO: God bless America. We have to talk about the transmission. This has the 8 speed automatic, a 7 speed manual standard. I believe that's the better transmission. This 8 speed, while it works great when you're in the track setting, when you're leaving it to its performance shift function when you're driving as fast as you can, the logic is great. As soon as you fall outside of that sort of dewy cycle, the manual shifts aren't that great. They're a little bit of a delay. I would much rather have the manual. I think overall, I really enjoy driving this car a lot. But it requires a lot more from its driver to reach its capabilities. ALISTAIR WEAVER: And that's not necessarily a bad thing. Super cars should be super. It should be a challenge. One thing that I just think is extraordinary in this car, probably the car's best feature, are the brakes. They're just fabulous. CARLOS LAGO: Absolutely. You know, you think that the Porsche would have the braking advantage. It's lighter. It's got the rear weight bias. But this thing stops so quickly and with so much confidence. ALISTAIR WEAVER: Should we drive the Porsche? [MUSIC PLAYING] Yeah, it's all right. Yeah, it's all right. Cold tires. CARLOS LAGO: 9000 RPM is a beautiful thing, isn't it? ALISTAIR WEAVER: It is a beautiful thing. And immediately, you just realize how agile this thing is. Doing a little bit of push when its tires are cold. CARLOS LAGO: With its natural aspirated engine, it's so responsive as soon as you dig into the gas pedal. ALISTAIR WEAVER: I think as we all go toward turbocharged engines, that's something that we're going to have to get used to. That wonderful throttle response and that undiluted sound, which we have with this 911, is going to go away. And even Porsche isn't sure how long they can hang onto this. CARLOS LAGO: This is such a different experience than the Corvette. It's about the same size when it comes to length. The Corvette's wider and lower in height. This is about 400 pounds lighter than the Corvette. But the steering feels even more so than that. ALISTAIR WEAVER: You really feel like you can just get into this. And it gives you an instant confidence. Whether you have the systems turned on or off, you can really start to feel what it's going to do. CARLOS LAGO: This is a very approachable car. And you're right. That's ridiculous to say about a 911 GT3, traditionally the raciest car in the Porsche line up. ALISTAIR WEAVER: But not in a way that means it's boring. This is still a track biased 911 and it still demands a bit of respect. CARLOS LAGO: My first two laps in this car were faster, it felt like, than the Corvette. There are specific parts on this track that hit the scarier hairier parts of this truck always five mile an hour faster, immediately. When you know what you're doing behind the wheel, you're still going to feel rewarded in this car. If you're a novice you're still going to feel good in this car. ALISTAIR WEAVER: Yeah. CARLOS LAGO: And that's quite a feat to accomplish. That's something the Corvette definitely doesn't do. ALISTAIR WEAVER: The Corvette very much feels like a normal road car that's been turned up to the max and they've tried all sorts of engineering trickery to make it do things that maybe just deep down it doesn't want to do, whereas this car is the evolution of 50 years of Germanic engineering. I think the steering is one of the best things about this car. In the Corvette it really wakes up in the corners. Here it feels very consistent and that gives you a much better sense of what the front end's doing and what the rear end's doing. CARLOS LAGO: I've got to say, I'm 5' 10", about 180. And this is probably the most uncomfortable bucket seat I've been in. ALISTAIR WEAVER: And I'm 6' 4". Probably a similar weight. CARLOS LAGO: Yeah. This might be the German spec seat. A little bit taller. A little bit skinnier. ALISTAIR WEAVER: I think you need to spend less time in the gym and eat a bit more. CARLOS LAGO: How do you feel about this transmission? ALISTAIR WEAVER: Well, this of course, is Porsche's PDK system, which is kind of like a manual transmission with somebody changing gear for you, is probably the easiest way to say. Whereas the Corvette has a more traditional automatic. So this is a lot sharper. A lot faster. And I think in manual alone, a lot more intuitive. In the Corvette you kind of have to think your way into the gear changes. Here, you just flick a paddle and away it goes. CARLOS LAGO: I agree. When they're both left to their own devices on the racetrack, the shift logic between them is fantastic. But when you want that manual control, the Corvette has a bit of a delay that requires more effort. And that's not so great. ALISTAIR WEAVER: Both these cars have carbon ceramic breaks, but of course in the Porsche, they're $9,000 more. But if you're seriously going to track it, I think it's going to be something that you have to have. CARLOS LAGO: I admire the fact that the Corvette just throws it in with the car because that's what the car does. ALISTAIR WEAVER: Yeah. But they are good in this car. CARLOS LAGO: For sure. ALISTAIR WEAVER: Brakes are-- I would say, maybe on the test track, no, it didn't stop quite as quickly, but out here they feel just as good as the Chevy's. Absolutely. CARLOS LAGO: Absolutely. We've gone over a lot of the performance hardware that these cars give you, but we haven't talked a lot about the software. Both of these cars have software on-board that is intended to help you be a better driver. In the Corvette's case, you have the performance data recorder, which is an on board video data logger system. And this, you have a phone app that you can put on the windshield. It records your video, logs your position, and tells you how fast you were relative to other laps. It's pretty cool tech. ALISTAIR WEAVER: The other thing I like about this car in terms of how you drive it is, like a lot of 911s on the circuit, you just take it in a little bit on the brakes. It just helps to get the nose in, counter that initial push, and then because of all that traction and where the weight sits, you can get hard on the power and it will just pull its way out without in these modern 911's going into any sort of lurid over-steer. But if you want to make this car over-steer, then actually, you really have to induce it by getting into a corner, lifting off, and then getting hard back on the power. And then it will do-- CARLOS LAGO: Beautiful things. ALISTAIR WEAVER: --anything that you want it to do. [MUSIC PLAYING] CARLOS LAGO: Beyond lapping and testing these cars, we've also lived with them for the past week. And what's been truly impressive is how easy they are to drive everyday. ALISTAIR WEAVER: If you detune the ZR1, it pretty much feels like every other Corvette. And although GT3 is noisier than a standard 911, it's by no means uncomfortable. Of course, both these cars are really practical. CARLOS LAGO: I just recommend skipping the bucket seats, unless you look like him. ALISTAIR WEAVER: Another top tip actually. If you're buying the 911, pay the extra $2000 for the nose lift kit, otherwise you'll be scraping your chin every day and that's not cool. CARLOS LAGO: Let's get to it. The Corvette ZR1 is a lot of fun to drive. It has tons of character and a lot of performance, but you have to be really on your game to access it. ALISTAIR WEAVER: In many ways, it's a kind of super car of the old school. It's worth remembering this too, the next generation Corvette will be mid-engine and a very different proposition. So if you want a bruiser like the ZR1, buy it now. CARLOS LAGO: The 911 GT3 three has a similar thrill, but it's easier to access at the racetrack. ALISTAIR WEAVER: And consider this, although it costs $25,000 to $30,000 more to buy new, the residual values on a GT3 are so much stronger than a ZR1, that over a three or five year life cycle, it might actually be the better financial choice. CARLOS LAGO: The Corvette ZR1 has the bragging rights. It's got the top speed. It's got the power. And it's going to be a really fun car for a small group of people. ALISTAIR WEAVER: But in terms of answering the question that we originally posed, which is the best car for fast road use that's also great fun on the track? Then for us, the only choice is the GT3. CARLOS LAGO: Agreed. ALISTAIR WEAVER: For more information on the GT3 and the ZR1, head to edmunds.com. CARLOS LAGO: And be sure to subscribe. [MUSIC PLAYING]

More about the 2018 Porsche 911

The 2018 Porsche 911 is available in a dizzying variety of configurations that range from properly quick to blindingly speedy. Unlike in previous generations, virtually all 911s — with a spectacular exception — are turbocharged. That's right: Even the base 911, the regular old Carrera, has two turbochargers heaving air into its horizontally opposed six-cylinder engine. And, yes, that engine is still hanging off the back of the 911 where physics suggest it shouldn't be — and Porsche's engineers make it work brilliantly anyhow.

To keep things confusing, the glorious 911 Turbo continues as the superstar of the Porsche 911 galaxy. We'll get back to that heavenly body in a few paragraphs.

Carried over from the 2017 model year, the engine in the Carrera is still a six-cylinder displacing 3.0 liters (down from the previous generation's nonturbocharged 3.4 liters), and thanks to its turbochargers, horsepower is up to a mighty 370 hp. Move up to the Carrera S model with its larger turbos, freer-flowing exhaust system and increased boost pressure, and the output of the 3.0-liter six rises to a spine-tingling 420 hp.

As before, the Carrera and Carrera S models are rear-wheel-drive, while the Carrera 4 and Carrera 4S are all-wheel-drive. All the Carreras are available with either a seven-speed manual gearbox or Porsche's Doppelkupplung (PDK) seven-speed, dual-clutch automatic transmission.

The Carreras are offered as coupes, cabriolet convertibles or the retractable-roof Targa 4 and Targa 4S.

And then there are the Turbo models. Using a twin-turbocharged 3.8-liter six-cylinder, the Turbo is rated at 540 hp; the Turbo S gets larger turbos and higher boost pressure to fortify the engine up to 580 hp. They are available as coupes or cabriolets and feature all-wheel drive and a PDK transmission. The Turbo models are simply some of the quickest and fastest cars available at any price. And the price is high.

OK, the nonturbocharged exception is the 911 GT3. This model gets a reworked engine for 2018, now a 4.0-liter six-cylinder (formerly 3.8 liters) that's never been near a turbocharger yet slams out an utterly exhilarating 500 hp and revs to 9,000 rpm. Whereas last year's GT3 was available exclusively with a PDK transmission, the 2018 model offers a six-speed manual gearbox (borrowed from the no-longer-available 911R model) as a no-cost option. The GT3 model is biased toward track performance and doesn't come cheap.

The EPA rates the 2018 911 Carrera coupe with the PDK dual-clutch automatic at 25 mpg combined (22 city/30 highway) and the mighty 911 Turbo S cabriolet at 21 mpg combined (19 city/24 highway). The narrowly focused GT3 model gets considerably lower mileage than that.

Beyond just the right engine and body, Porsche offers a blizzard of expensive options. Use the buying tools on Edmunds to find the right 2018 Porsche 911 for you.

Should I lease or buy a 2018 Porsche 911?

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.
