The 2013 Essen Motor Show opened its door this week and as every year the tuning world doesn’t cease to amaze us. The latest super tune comes from BBM Motorsport and its BMW M6 Convertible which now produces 705 horsepower. In standard form, the M6 is powered by the S53Tu 4.4 liter V8 TwinPower turbocharged engine employing the M division’s patented manifold that evenly spaces out exhaust pulses. With a peak turbo boost of 21.7 psi, the M-built engine produces 560 hp and 500 lb-ft of torque delivered in a flat band between 1500 and 5750 rpm.

Whopping out 705 hp is the result of a tuning cure which includes a new exhaust system with down pipes, catalytic converters and Akrapovic exhaust system. It also produces 800 Nm (590 lb-ft) of torque. The company has not revealed what software upgrades were done to the car, but most likely this is one of the most aggressive tune ups out there.


The performance of the 705hp M6 is also unknown, but we anticipate a 0 to 100km/h (62mph) time in less than 4 seconds.

To stay in tune with the latest trends, the BMW M6 Convertible by BBM also gets a frozen grey paint job.
