Lighter, faster, more powerful and more efficient than the current M3.
Rumor had it that the F82 M4 coupe had begun its public testing, and now that’s been confirmed by spies who spotted it for the first time in and around the BMW M Test Center at the Nurburgring!
Although the BMW prototype wears the typical mule camouflage, there’s still plenty to see. The camo mule caused little doubt that it is in fact the M version of the upcoming F32 4 Series coupe. Signature features could be spotted like the M quad exhausts, the flared fenders, signature blue M brakes, wide tires, and M6 steering wheel.
Front and rear fenders on the M4 coupe are significantly flared and stretched compared to the F32 4 Series prototypes
Rear flare is easy to spot, while the front is less conspicuous – a the gap in the front fender camouflage clearly shows the front fender as much wider than the rest of the side body.
Stretched fenders will accommodate a wider track for the M4 – vs the regular 4 Series
Sleeker version of the F30 3 Series front end
Sportier lights and grilles
M styled front bumper
Mirrors are from the F30 3 Series – for testing purposes only – final production mirrors will be sportier
Carbon Fiber Roof / Brakes
Shift paddles in the interior – optional or standard manual transmission
Steering wheel from the new M6
Powered by an inline 6 cylinder engine with multiple turbochargers
Engine output approximately 450 horsepower
Rumored reworked and reinforced N55 6-cylinder engine with a strengthened aluminium block with a heavily modified cylinder head
Induction technology will be completely new as will be the latest bi-vanos variable valve timing
The F82 M4 will most likely NOT be constructed extensively from carbon fiber (CFRP) as earlier reports had rumored. This next generation of M3/M4 had begun its development two years ago, which is said to have been too early to take advantage of BMW’s CFRP developments.
Even without the CFRP construction, the M4’s new aluminum chassis, and aluminum and reinforced plastic body panels will make it lighter than the current M3 sedan and coupe.
The 2015 BMW M4 Coupe is looking to be introduced no earlier than late 2014.
