German tuner Noelle Motors have seriously increased the performance of the latest BMW M6 Convertible. Under the lead of Karl-Otto Noelle, former head of engine development at BMW Specialist tuner Alpina, Noelle Motors have managed to squeeze 766hp out of the M6 Convertible.
In stock condition, the BMW’s 4.4 litre twin-turbo V8 outputs 575hp and 680 N.m. of torque. After installing Noelle Motor’s stage 3 performance kit, the performance of the BMW convertible skyrocketed to 766hp and 882 N.m. of torque. The main source of the power increase lies in software optimization and installment of exhaust downpipes with free-flow sport metal catalytic converters.
The software upgrade includes removing the car’s original electronically regulated speed limit, making it possible for the upgraded M6 Convertible to reach 345 kilometers an hour. The catch however is that the Noelle Motors stage 3 performance upgrade is considered illegal in Germany, and is therefore suitable for export only. The stage 1 and stage 2 performance kits, capable of bringing the BMW M6 Convertible to a solid 700hp, are favorably deemed legal in Germany.
Additional to the performance upgrades Noelle Motors delivers, the German tuner optionally offers mufflers, sport exhaust systems, a coil-over suspension kit and various alloy wheels and tyre combinations to go with the upgraded BMW M6 Convertible.
