Which M4 does Edmunds recommend?
Edmunds' Expert Review
The 2018 BMW M4 represents an ideal marriage of sporting capability and luxury in one car. Based on the brand's 4 Series, the M4 receives comprehensive upgrades that make it equally capable of flying along a mountain road, lapping a racetrack or just comfortably commuting to work.
Essentially, the M4 is the hot-rodded version of the 4 Series coupe and convertible. It gets the typical BMW M division treatment, including a significantly more powerful twin-turbo inline six-cylinder engine, stickier tires, bigger brakes and subtly more aggressive styling. The conversion to M status doesn't diminish the 4 Series' luxury quotient either. The ride is compliant enough to drive the M4 and enjoy it daily, the seats are comfortable for a road trip and the interior still boasts attractive materials and logically placed controls. And even though it's a two-door, the M4 has decently roomy rear seats and a useful trunk.
If you're looking for a sports car that's more livable day to day or you want something a little more exciting than the standard luxury coupe or convertible, you'd do well to pick the 2018 BMW M4.
2018 BMW M4 configurations
The 2018 BMW M4 is a two-door, four-passenger high-performance car that's based on the company's 4 Series and offered as a coupe or a convertible. We're big fans of the M4's excellent balance of performance and comfort. And while we'd recommend buying a few optional extras, the M4 is going to be a joy to drive every day regardless of how you equip it.
As you'd probably expect with a high-end two-door such as the M4, there's plenty of standard equipment. For starters, you get a turbocharged 3.0-liter inline six-cylinder engine (425 hp, 406 lb-ft) and either a six-speed manual transmission or an optional seven-speed, dual-clutch automatic. Also included is launch control, automatic rev-matching on downshifts, 18-inch wheels with summer tires, an adaptive sport-tuned suspension (a standard nonadaptive suspension is a no-cost option), an electronically controlled rear differential, keyless ignition and entry, dual-zone automatic climate control, leather upholstery, power front sport seats with heating, driver-seat memory settings and fold-down rear seatbacks.
In addition to the performance and cabin basics, the M4 has a decent amount of standard tech equipment, including an 8.8-inch display screen with BMW's iDrive infotainment interface, a rearview camera, a 16-speaker Harman Kardon surround-sound audio system, Bluetooth, navigation, a suite of smartphone and online applications under the BMW ConnectedDrive banner, HD radio and satellite radio, a USB audio input and a CD player.
A few key optional packages are available for the M4 as well. The Competition package ups the M4's power rating to 444 hp and adds 20-inch wheels, revised settings for the adaptive suspension, an even sportier exhaust and some interior trim upgrades such as M stripes on the seat belts. The Executive package adds full LED headlights, automatic high beams, side- and top-view cameras, an automated parking system, head-up display, and speed limit information.
Other options include 19-inch wheels, carbon-ceramic brakes, a heated steering wheel, parking sensors, blind-spot monitoring, a power rear sunshade (coupe only), a head-up display, Apple CarPlay and wireless device charging.
On the coupe, you get your choice of either a roof made of carbon-fiber-reinforced plastic or a traditional steel roof with a sunroof. The M4 convertible has a power-retractable hardtop with a wind blocker, as well as extended leather upholstery and door trim incorporating sun-reflective technology. When equipped with the Executive package, the convertible also includes front-seat neck warmers.
Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our Full Test of the 2015 BMW M4 Coupe (turbo 3.0L inline-6 | 6-speed manual | RWD).
NOTE: Since this test was conducted, the current BMW M4 has received some revisions, including the addition of standard adaptive suspension and an optional Competition package, which increases horsepower. Despite those changes, our findings remain broadly applicable to this year's BMW M4.

2018 BMW M4 videos
[MUSIC PLAYING] CARLOS LAGO: This is the 2018 BMW M4. It's got the competition package, which means it has 444 horsepower. We're going to do an acceleration run, which should be a bit of fun, considering you have that power, a rear drive car, and a six speed manual. Now, we'd like to start by doing what we call the key up run. Assume you had just turned the car on, let it warm, up and jumped on the gas, and found out what would happen. That's what testing is, after all. I have got to key up settings on. So comfort everything, from the steering, to the suspension, to the gas pedal. And I think I mentioned the stability control too. Let's go with a 2800 RPM launch. So a little bit of slip before stability control comes on. This 3 liter straight or V6, to a straight-six. Ha. You saw that. This test track we're doing the acceleration run on has a few bumps. The bumps are apparently big enough to trigger the stability control. That could be interesting. So for run number two, I'm going to put the gas pedal aggressiveness in sport. I'm going to put the dampers in the sport plus to see how they do with those bumps that we're hitting. And I'm going to put the steering in sport, because why not. I'm feeling sporty. Stability control and trash control are now completely off. We'll go with let's say a 2,300 RPM launch. And we'll come off the clutch quickly instead of sidestepping it. Very quick, very quick car. You've got to take your time with the shifter. You can't do it too quick. A little rubbery with the feel. Though, I kind of like it. It's a classical BMW feel. The rear end of this car when it gets a big bump, there's so much power going to those tires that it feels like it's almost about to lose traction. It doesn't. It stays straight and true. But I've got to say, it's surprising at how loose that rear end can feel under straight acceleration. OK. Here we go. Run number three. We're going to see if we can bump up the RPMs a little bit and get a smoother launch out of the car. There we go. Bump one. You've got to consider that where I'm hitting the bumps on the straightaway are always right at the top of the gear. So like at 7,400 RPM, 7,300 RPM, there's that bump. And that's when the engine's doing peak power, I think. It may be doing peak power a lot lower at the engine speed. A lot of power are going to those rear tires when the rear axle gets that bump. I wish it was a little bit better controlled. Run number four. Here we go. Yes. Yeah. A little bit of wheel spin right at the top. I I think I was a little too high on the engine speed right there. I've got to say, for a car with this much power going to the rear wheels, with a traditional six speed manual layout, it's not a too difficult of a car to launch. The motor rips. I've said that before, but it's worth repeating. This thing has a ton of power. It sounds really good at high RPMs and not so great at low RPMs. It's kind of hard to fault it over power delivery. I just wish the rear end was a little bit more buttoned down. So that's going to wrap up this episode of how to accelerate your BMW M4.

2018 BMW M4 Competition Package Acceleration Test
Edmunds Senior Writer Carlos Lago tests the acceleration of the 2018 BMW M4 equipped with the Competition package. Though pricey, this option package comes with a bunch of worthwhile upgrades, including lighter forged wheels and revised steering, suspension, differential and stability control settings. The engine output rises to 444 horsepower, and BMW says this newfound power helps shave 0.1 second off the M4's 0-60 mph acceleration time. Our test track is the perfect place to validate that claim.

BMW M4 vs. the competition
2018 BMW M4
2018 Audi S5
BMW M4 vs. Audi S5
The freshly redesigned Audi S5 is an interesting alternative to the BMW M4's dominance over the segment. It's not as quick (or as expensive), and its use use of all-wheel-drive gives a different feel than you get in the rear-wheel-drive M4. But in terms of luxury and driving excitement, the Audi S5 goes toe to toe with the BMW.
BMW M4 vs. Mercedes-Benz C-Class
Mercedes has stepped up its high-performance game in recent years, and a great example is the AMG C63. This top-end C-Class is offered as a sedan, coupe or convertible and boasts a turbocharged V8 good for 469 hp, or 503 hp with the upgraded C63 S version. You get more power out of the C63, but the M4 has a slight edge in handling precision.
BMW M4 vs. Porsche 911
Like the BMW M4, the Porsche 911 is a legend — but it's an expensive one. The base model 911 costs nearly as much as a fully loaded M4, and though it's certainly enjoyable to drive, you'll need to spend a lot more money to approach a properly optioned M4's level of performance.

Is the BMW M4 a good car?
The M4 achieves a balance that few cars in its class can manage. It offers sporting performance, luxurious accommodations and a comfortable ride, all in the same vehicle. Though BMW offers several performance enhancements for the M4, all versions share these common strengths. Our few complaints are minor ones. Being a two-door limits its usability, with awkward backseat access and limited trunk room. The M4's steering, though sharp and precise, doesn't offer enough feedback (especially compared to steering in past M3 coupes), and the enhanced engine sounds developed by the M4's stereo system are no substitute for the real thing.
Does the BMW M4 have good MPG?
EPA fuel economy rating for the M4 Coupe is 20 mpg combined (17 city/25 highway with the manual transmission and 17 city/24 highway with the automatic transmission). Opting for the extra horsepower of the Competition Package does not change the EPA's estimated fuel economy. The M4 convertible gets the same fuel economy as the coupe with a manual transmission. But fuel economy drops to 19 mpg combined (16 city/22 highway) with the automatic transmission.
Does the BMW M4 have good resale value?
If you're ready to buy, you're probably wondering about the BMW M4's resale value. How much will a 2018 BMW M4 be worth in two or five years — or whenever you decide to sell? Check out the Edmunds True Cost to Own (TCO) calculator. It includes projected annual depreciation over the first five years of ownership based on Edmunds' robust market transaction data.
Providing an excellent balance of performance and comfort, the 2018 BMW M4 is one of our top choices in the high-performance luxury coupe and convertible segment. It's relatively plush and blisteringly fast, and it's one of the few cars in this class still offered with an engaging six-speed manual transmission. It truly lives up to the illustrious M badging. There's only one trim level for the M4. But you can choose between a coupe or a convertible, and you can add a seven-speed, dual-clutch automatic transmission if the three-pedal setup isn't for you. Don't dismiss the six-speed manual outright, though — it's great for drivers who love a connected feel and it makes sense in a car such as the M4. There are a few main bundled options packages and stand-alone options to choose from, which is typical from BMW.
The Executive package offers appealing (maybe even necessary) luxury and safety features including automatic high beams, side- and top-view cameras, and a head-up display. As is typically the case in this class, several option packages can add up very quickly. Combine the M4's packages with the myriad of stand-alone options and you can have a pretty customized BMW, but your wallet will definitely feel a bit lighter. Most of the M4's key competitors fall victim to the same pricing pitfalls.
The 2018 BMW M4 is one of the more expensive vehicles in its class, especially when you consider the amount of equipment you can get from key rivals for the same price. But the quality you get in the M4 is worth the trade-off. Materials and build quality alone would be enough for the M4 to stand out from the crowd, but excellent drivability and performance give it an even sharper edge. Sort through all the details and pick the right combination of options for you on Edmunds before heading to the dealer. We'll help you find the perfect car to meet your every need.

Should I lease or buy a 2018 BMW M4?
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.
