Starting July 2015, BMW will replace the current Competition Package for the M6 Coupe, M6 Gran Coupe and M6 Convertible with an upgraded version. The most notable feature is that the power boost for the 4.4-liter twin-turbo V8 petrol engine is 40 hp (29 kW) and 20 Nm (15 lb-ft) of torque.
This means that the V8 engine fitted with M TwinPower Turbo Technology will offer 600 hp (441 kW) and 700 Nm (516 lb-ft) of torque available between 1,500 and 6,000 rpm.
BMW says that the combined fuel consumption will be 9.9 l/100 km (28.5 mpg imp) for the M6 Coupe and M6 Gran Coupe models, while the M6 Convertible will need 10.3 l/100 km (27.4 mpg imp). Combined CO2 emissions will be 231 g/km for the M6 Coupe and M6 Gran Coupe and 239 g/km for the M6 Convertible.
The power increase means that the vehicles will be faster and according to BMW, the M6 Coupe and M6 Gran Coupe will be able to hit 100 km/h (62 mph) in 3.9 seconds, while the M6 Convertible will need 4.0 seconds.
11.8 seconds will be needed for the M6 Coupe and M6 Gran Coupe to reach 200 km/h (124 mph), which means it is 0.6 seconds faster than the previous version of the Competition Package which offered 575 hp (423 kW).
Top speed for all the models equipped with Competition Package is limited at 250 km/h (155 mph), while the M Driver’s Package increases it to 305 km/h (189 mph). Furthermore, the Competition Package improves the vehicles’ handling due to the fact that the chassis technology is tuned precisely to the performance characteristics of the powertrain.
In addition, the springs, dampers and anti-roll bars get firmer tuning, while the Active M Differential further improves tractions.
BMW says that the steering with M-specific Servotronic function has more direct mapping while the M Dynamic Mode of the DSC (Dynamic Stability Control) system is focused on delivering sporty handling. Regarding the design, the BMW M6 Competition models receive 20-inch M light-alloy wheels (double-spoke 601M bi-colour) and mixed tyres, as well as black chrome twin tailpipes. [source: BMW]
