2015 BMW M4
By Laura Burstein
On Sale: May 2014
Expected Pricing: Starting around $65,000
A new 2015 BMW M4 goes on sale this spring replacing the outgoing M3 coupe. M4 brings the coupe in line with BMW's new nomenclature that uses odd numbers to denote sedans, and even numbers for coupes. The all-new high performance coupe from BMW's track-ready M division made it its official debut at the North American International Auto Show in Detroit January 2014.
Sharing the same powertrain with the new M3 sedan, the 2015 BMW M4 uses a new version of BMW's much-loved turbocharged inline-6. The 3.0-liter powerplant cranks out 426 horsepower and 406 pound-feet of torque (on tap from as low as 1850 rpm), more than the V8 used on the outgoing M3 coupe.
Engineers shaved off a little weight, also; the M4 weighs 176 pounds less than the old M3 coupe, thanks in part to a body that uses a greater percentage of aluminum and carbon-fiber-reinforced plastic. The M4 also gets a carbon fiber roof.
With increased power and reduced weight, the BMW M4 can dash from 0-60 mph in an estimated 4.1 seconds, according to BMW. Transmission choices include a 6-speed manual or a 7-speed dual-clutch. All M4s will be rear-wheel drive.
Unlike the M3's more upright stance, the BMW M4 is slightly leaned-back, with a signature BMW twin kidney grille that is ever-so-slightly lower and wider. Large front air intakes are functional and give the M4 an aggressive look. Vertical vents alongside the front fenders channel air down the sides of the car. A rear integrated lip spoiler keeps the car planted, while a smooth underbody and rear diffuser help the M4 to slice through the air with as little resistance as possible.
A lightweight suspension uses a double-joint spring strut setup in front and a five-link axle in the rear. Most components, including control arms, are aluminum. An optional adaptive suspension allows drivers to choose between different driving modes.
Steering effort can also be adjusted independently of the suspension; drivers can choose between Comfort, Sport and Sport + modes.
Inside the cabin, the design is similar to that of the BMW 4 Series coupe, but splashier with a variety of colors and finishes. Sport seats retain their signature contrast stitching, and carbon fiber panels are left exposed for a race-ready appearance. The M logo can be found everywhere, reminding drivers that they paid a premium for a much faster car than those regular BMWs.
Also available is a BMW M lap timer app, which lets drivers analyze their driving style via a paired smartphone. The app will record vehicle speed, lateral acceleration engine revs, steering angle and more, and can also record two laps on the same track, allowing a corner-by-corner comparison. Other options include a head-up display, navigation, adaptive LED headlights and collision warning system.
The 2015 BMW M4 is expected to go on sale in the U.S. in May 2014. Pricing won't be announced until closer to the on-sale date, but, as with the 4 Series coupes, we expect a price premium over the sedan. Our best guess? Around $65,000.
