To drive the BMW M4 is to love the BMW M4. Nothing else matters—not the styling, the interior, the technology, or safety scores, though the M4 does does well in all of those areas. No, as any driving enthusiast with gasoline flowing through their veins will tell you, get the driving part right, and everything else is forgiven. And the drive is where the BMW M4 sets itself apart.
The heart and soul of the BMW M4 is its direct-injected, twin-turbocharged, 3.0-liter inline-six-cylinder engine, which it shares with the M3 sedan. The standard M4 engine produces 473 horsepower at 6,250 rpm and 406 lb-ft of torque between 2,650 and 6,130 rpm. The engine in the M4 Competition is further tuned to deliver 503 hp at 6,250 rpm and 479 lb-ft between 2,750 and 5,500 rpm. Redline for both engines is 7,200 rpm.
Both versions of the M4's twin-turbo engine work with either a six-speed manual or an eight-speed M Steptronic automatic transmission, the latter is standard on Competition models to handle the extra engine torque. BMW M4 Competition models also feature a separate transmission oil cooler. The Steptronic features both automatic and manual modes, controlled by the Drivelogic switch on the gear shift lever for those who like a little more control over gear selection. Additionally, three drive modes are available: comfort, sport, and track.
According to BMW, the standard rear-wheel drive (RWD) M4 can accelerate from zero-to-60 mph in 4.1 seconds, while the M4 Competition can do the deed in 3.8 seconds. The M4 Competition xDrive is quicker still, taking just 3.4 seconds to reach 60 mph thanks to the AWD system's extra grip. Top speed is a claimed 155 mph for the M4 and 174 mph for the M4 Competition (180 mph for vehicles equipped with the M Driver's package, which also comes with a unique one-day high-performance driving class at a BMW Performance Center).
While we can't (and, even if we could, we wouldn't) verify BMW's top-speed claims, we can vouch for the M4 Competition's brisk acceleration from a standing start. If we didn't know we were driving a vehicle powered by an internal combustion engine, we'd swear we were piloting an electric vehicle with its instant torque and accelerative forces that press your head and shoulders to the seatback. It was such a hoot performing zero-to-60 runs that we found ourselves seeking out victims, er, passengers to demonstrate the M4 Competition's astounding off-the-line performance. It was that much fun, and we didn't want it to end.
While the initial acceleration was EV-like, the sound emanating from the engine/dual-branch exhaust system was anything but and only served to enhance the experience. For those that prefer a quieter exhaust, the M4 is outfitted with an M Sound button, which allows the driver to reduce the engine note when desired and works in any drive mode.
Once at speed, the M4 Competition handled like a boss. Part of this was due to the M4's chassis and suspension tuning. The newly available xDrive AWD system also kept the BMW composed by distributing torque between the front and rear axles via an electronically controlled multi-plate clutch. The M xDrive system is unique because it offers three different modes to allow drivers to custom-tailor their drive. The default setting, 4WD is rear-wheel-biased and emphasizes traction and handling. The 4WD Sport mode sends more torque to the rear wheels during spirited driving and is best suited to a track environment. Meanwhile, 2WD mode requires the car's stability control system to be turned off and provides the purest, most electronic nanny-free driving experience.
The M4 Competition's standard forged light-alloy M double-spoke 19-inch front and 20-inch rear wheels wear grippy Z-rated tires that enabled the car to handle like it was on rails. Testing the car's cornering ability on decreasing-radius on- and off-ramps was particularly fun. The standard M Compound brakes worked incredibly well, quickly bringing the M4 down from speed with no drama or fade during our repeated runs.
Bottom line, if there were a way to give the M4 extra credit for performance on our 10-point scale, we'd most certainly go all Spinal Tap and "turn it up to eleven."
