BMW recently unveiled the M3 and M4 Coupe at the North American International Auto Show, but our spies have just snapped new photos of the M4 Convertible.
Caught undergoing cold weather testing, the drop top will follow in the footsteps of the M4 Coupe and adopt an aggressive body kit with modified bumpers, revised side skirts and ventilated front fenders. We can also see a bulging hood, a four tailpipe exhaust system and a retractable hardtop.
Power will be provided by a 3.0-liter TwinPower Turbo six-cylinder engine that develops 431 HP (317 kW) and 406 lb-ft (550 Nm) of torque. This enables the coupe to accelerate from 0-100 km/h in as little as 4.1 seconds, so expect the convertible to be a few ticks slower.
