• 2015 BMW M3

The BMW 3 Series entered a new generation for the 2012 model year, and three years later, we finally got to lay eyes on the new BMW M3. Of course, you can’t mistake for a Bimmer, thanks to those double kidney grilles, but its new look is a clear evolution of the ultimate 3 Series Model. Highlights of the exterior include a significantly more aggressive bumper with corner air inlets that could eyeball you from across the room, a dew design for the rear fascia that makes the rear end look far less like a Honda Civic. Rounding out the exterior are new exterior light units all the way around. Inside, the car gets the standard M treatment for the steering wheel, door sills, dead pedal, gear shifter, and trim. The most important part of the new-gen M3 is the new 3.0-liter, turbocharged, I-6 under the hood that’s good for 425 horsepower and 406 pound-feet of torque.

The M3 has been a legend for a while now, tearing up asphalt since its debut back in 1983. It’s smaller so it is nimble, but it has always had significant power under the hood, making it the best of both worlds. With this new generation, BMW engineers were targeting perfection. With more than 400 ponies and enough torque to burn of a set of tires after just a few hours of “playing” the 2015 M3 is about as close to perfect as you can really get. With all of that out in the open, it’s about time for you to learn all about the new M3, so check out our full review below.

Rendering Vs. Reality

2015 BMW M3 Exterior Computer Renderings and Photoshop

We created our rendering back in September 2013, and despite not seeing much of the actual model, it was not too hard to decipher what the new M3 would look like. All we had to do was take the revised 3 Series Sedan and add in the typical M elements, like the five twin-spoke wheels, an aggressive front apron and hood and some ground effects. Comparing our rendering to the actual leaked images shows that our artist was on the money with his vision of the M3.

The exterior is beautifully BMW. It’s a solid evolution in the 3-Series line that will certainly age well. The look is certainly one of understated aggression that combines the calm demeanor of a normal car with the menacing snarl of a true M3.

Four real doors with useable interior space means the M3 can accommodate three friends on the ride of their lives. The pictures, however, speak for themselves.

Looking deeper, we see many exterior additions to the M3 the standard 3-Series

simply lacks. A huge front apron, smooth underbelly, and Gurney rear spoiler keep the air moving properly around the car. Downforce is also a key reason for the exterior accoutrements. Past the front grille, air is purposefully directed beyond mere cooling reasons. Air is channeled through the engine oil cooler and creates a Venturi effect that reduces front axle lift, which in turn, improves steering.

Twin-stalk style side mirrors and integrated air breathers (the vertical M gills) reward of the front wheels help move air round the car without creating turbulence or drag.

The BMW feel and flair that become standard on 3 Series is alive and well in the new M3. A carbon-fiber dash insert, the tri-spoke steering wheel and the infotainment system are all familiar. Details, like the M-designed door sills, dead pedal, gearshift lever, leather steering wheel with chrome trim and circular instruments with white graphics, give an upscale and sportier appearance.

Strong bolstering in the front seats keep occupants snugly in place and are completely adjustable. Power operation and heating elements are still available for those looking for the touches of comfort, while twisting through the corkscrew at Laguna Seca. Four adults are able to ride without issue, although there are better sedans available for long distance travels.

2015 BMW M3 Drivetrain
- image 525713

Under the hood is where BMW engineers made some unexpected changes. M3s of yore were powered by perhaps the sweetest inline six-cylinder engines to ever grace an engine bay. Naturally aspirated with a crazy high redline, the legendary 3.2-liter I-6 made 333 horsepower and could propel and E46 M3 from naught to 60 mph in roughly 4.5 seconds.

BMW has taken a page from the history books, combined it with the latest forced-induction technology of the 21st century, and introduced its next step in in-line engines: the 3.0-liter, twin-turbocharged I-6, coded the S55.

BMW says the new engine produces 425 horsepower from 5,500 to 7,300 rpm and 406 pound-feet of torque from a low 1,850 through 5,500 rpm. Those numbers haven’t been validated yet, but we imagine they are close to reality. The M TwinPower Turbo engine also boasts a lighter weight than the outgoing 4.0-liter V-8 and a 25-percent increase in fuel economy.

Two transmission options are available: a standard six-speed manual transmission and a seven-speed M Double Clutch transmission. Both transmissions have electronic features that make any driver look like a professional driver. The six-speed has an automatic throttle-blip system, much like that of the 2014 Corvette C7’s Rev Match system, that gooses the throttle within the split seconds between gears during a downshift, increasing smoothness of shifts.

The M-DCT is the techo-buff’s choice. Lighting fast shifts in manual mode enables shifts without an interruption of power to the wheels. Integrated Launch Control helps get the M3 off the line without fuss. Once underway, Stability Clutch Control helps redirect the car if understeer is detected by opening up the clutch to bring it back in line. Drivelogic is also standard of the M-DCT and offers different driver-selectable modes ranging from comfort and economy to sport and track settings.

Dividing up all the power is BMW’s Active M Differential, which uses an electronically

controlled, multi-plate, limited-slip setup designed to lay power down most effectively. Its takes into account the throttle position, rotational speed of the wheels, steering angle, and the car’s yaw rate – all coming from the Dynamic Stability Control system. The systems work as a whole to get the M3 moving quickly out of corners, even with less than ideal surface conditions. Thankfully, BMW gives enthusiasts the ability to turn the system into a less-intrusive mode. The M Dynamic Mode, a sub function of the DSC system, allows for more wheel slippage and yaw rates than normally acceptable. Let the hooning commence.

Keeping all that technology cool on race day can be a challenge, but one the BMW engineers met some serious solutions. Perched alongside the turbo is an indirect intercooler that maximizes charger pressure. Besides the main radiator, the M3 is also cooled by a water cooler positioned to the side of the high- and low-temperature water circuits, along with the engine and transmission oil coolers. The turbos get their own electronic water pump that keeps the bearing mounts from frying while the M3 is stationary.

At the end of the day, the M-DCT-equipped M3 hits 60 mph in just 3.9 seconds to the 4.1-second sprint of the six-speed-equipped model.

What lies underneath the new M3 is just as impressive as the drivetrain, if not more so. Low weight and high rigidity topped BMW’s list for essential inclusions for all the suspension and axle components.

The double-joint spring struts, control arms, wheel carriers, and axle subframes all use a lightweight aluminum construction. Five kilograms (about 11 pounds) are gone in the front axle alone when compared to the outgoing unit. Play-free ball joints and elastomeric bearings work with a rubber-bushing-free, five-link rear suspension to keep things tight.

Those missing rubber bushings are a mixed blessing. Handling should be superb with very little play, but will be on the harsh side with little forgiveness on rough surfaces or speed bumps. Such a compromise might relegate the M3 to more of a track-only car rather than the perfect all-rounder the past models were known to be.

Besides the missing rubber bushings, the rear axle is also short three kilograms (6.6 pounds) of weight as well. The control arms and wheel carriers are manufactured using forged aluminum, as are the 18-inch and optional 19-inch wheels. The reduced unsprung mass is said to improve handling without compromising the ride comfort, but we have our doubts about such claims.

The all-new CTS Vsport takes the place of the outgoing CTS-V sedan — so we assume — and it is one of the M3’s key competitors. It makes use of a 3.6-liter twin-turbocharged engine that cranks out 420 horsepower and 430 pound-feet of torque. Sure, that’s a little lower than the M3 and its estimated 4.6-second 0-to-60 mph time will likely be a little slower than the M3’s sprint. Then again, we love the new look of the CTS, whereas the M3’s look is a little aged, despite its mild refresh.

The 2014 C63 AMG is not on the market yet, but Mercedes-Benz has outlined the new C63 AMG "Edition 507." It checks in with a 6.3-liter, V-8 engine that churns out 507 horsepower at 6,800 rpm and 450 pound-feet of torque at 5,200 rpm. This, combined with an AMG SPEEDSHIFT MCT seven-speed sports transmission, launches the speedy Benz sedan to 60 mph in 4.1 seconds and up to a top speed of 174 mph.


The BMW M3 has been a staple of two- and four-door performance for over 25 years, and this latest version is an evolution of that. BMW did not reinvent the wheel with the 2015 M3, but rather made improvements where they were needed. Carbon Fiber and Carbon Fiber Reinforced Plastics find their way into the sedan to the benefit of weight-savings and rigidity.

The decision to introduce the two-door 4 Series and its subsequent M4 will leave the M3 to thunder around with four complete doors for the foreseeable future, while the M4 will likely see many tuners gravitating towards the smaller car for hard-core track tuning. Either way, we’re glad BMW split up the models and created some much-needed consistency within their model lineup.

Update History

UPDATE 07/08/2011: The British magazine AutoExpress has revealed new details about the upcoming generation BMW M3 set to be released in 2014. It seems that the new BMW M3 will be powered by a fresh 3.3-liter six-cylinder engine equipped with three turbos – one powered by electricity, rather than the exhaust gases. Output will be around 450 horsepower (up from the current output of 420 horsepower). The body will feature a mix of steel and ultra-light carbon fiber-reinforced plastic.

UPDATE 08/16/2011: Three turbos? Not so, says Autocar, whose sources are telling them that the future M3 will feature a new twin-turbocharged 3.0-liter, six-cylinder engine that is currently under development. This source describes the new engine "as being heavily differentiated from the company’s existing twin-turbocharged ‘N54’ and twin-scroll turbocharged ‘N55’ 3.0-liter engines." Apparently, the new engine will come with a management system, induction system, cylinder head, pistons, and connecting rods. We were kind of pumped about the three turbos so we’ll just have to wait and see what develops.

UPDATE 11/03/2011: BMW has filed a new patent for an electric-powered turbocharger, bringing back the old rumors about a new 3.3-liter six-cylinder engine equipped with three turbos. Hit the jump for details on this new technology! (F30Post)

UPDATE 05/22/2012: President of BMW North America, Mr. Ludwig Willisch has finally confirmed that the next M3 will feature an in-line-six layout - the same layout that will be used for the M4.

Willisch also said that, at some point, BMW was indeed considering a V6 engine for the next M3, but in the end, this choice was dropped. What he didn’t specify was whether or not the new inline-6 engine will get bi-turbo or tri-turbo. Regardless of the technology, the future M3 will deliver at least 450 horsepower.

Ludwig Willisch also confirmed that the next M3 will be lighter, faster, more powerful, and more efficient than the current M3. It will be offered with an optional or standard manual transmission.

Updated 08/13/2013: BMW has dropped a teaser video of the upcoming M3 sports sedan. The video offers us the first listen to the new straight-six engine.

Updated 08/28/2013: Our spy photographers caught the 2014 M3 out testing again, but this time, it is wearing very little camo. Basically, BMW only covered up its M styling goodies and the new to-the-grille headlights. You can see the newest spy shots after the jump.

Updated 9/5/2013: Since our rendering of the M3 Sedan was getting a little long in the tooth, we decided to make up a new one for you to drool over. Essentially, it borrows all of the M4 styling elements — bumpers, side skirts, mirrors, wheels, side vent, hood vent, black kidney grilles and roof — scaled down to a 3 Series. Additionally, we updated the rendering with the forward-leaning grille and the to-the-grille headlights. You can see the rendering above and a side-by-side comparison of the old and new renderings after the jump.

Updated 9/25/2013: BMW officially confirmed today the numbers for the new in-line six-cylinder engine that will be used for the new M3. Click past the jump to learn more about it.

Updated 12/11/2013: The first official images of the new BMW M3 Sedan leaked online today, just before the car’s official debut tomorrow morning. The images came from BMW Blog, which was asked to remove them, but it was a little bit too late. Click past the jump to see what the new M3 Sedan offers.

Leaked Images

The new generation BMW M3 features a completely redesigned front look, with a black kidney grilles surrounded in chrome and larger front air intakes, and of course, a redesigned hood that features a power dome.

As rumored, the new M3 will get indeed a carbon fiber roof to help keep the center of gravity low.

The rear is also revised, and includes a new bumper with a redesigned diffuser and a quad-tailpipe exhaust system that is sure to deliver on hell of a sweet note.

There is also new, five twin-spoke alloy wheels combined with gold brake calipers peeking from behind.
