3.6 seconds. Not too bad for a car that weighs 4,177 lbs (1,895 kg), is it?

There’s still no word about the possibility of a fully-fledged M7, so those interested in a fullsize, high-performance Bavarian sedan can either settle for the 750i or pay more for the faster 750i xDrive. Noelle Motors worked on the former which in standard configuration runs to 62 mph (100 kph) in 4.7 seconds. After fiddling with the biturbo 4.4-liter V8 engine, the German tuner managed to slash the sprint time to only 3.6 seconds which is basically supercar territory.

It was all possible by bumping output from the series 450 horsepower (330 kilowatts) and 480 pound-feet (650 newton-meters) of torque to a healthy 629 hp (462 kW) and 605 lb-ft (820 Nm). The additional power was obtained via the usual recipe: modified turbochargers, remapped ECU, custom exhaust, and optimized software.

With the power upgrade module installed, Noelle Motors’ car is not only 1.1 seconds quicker than a stock 750i, but also a tenth of a second faster in the sprint than the mighty 610-hp, V12-powered M760Li xDrive. Details concerning top speed are not available, but it should eclipse the 189 mph (305 kph) achieved by the flagship 7 Series when fitted with the optional M Driver’s Package. If you’re after top speed, Alpina’s recently introduced B7 Bi-Turbo can max out at an amazing 205 mph (330 kph).

For those who would rather have something straight from BMW, we spotted a mysterious high-performance 7-Series earlier this year in Sweden, so maybe that was an early sign of an M7. Only time will tell.
