German tuner Manhart Racing has just revealed their latest treatment called "MH5 S-Biturbo," especially developed for the BMW M5. Offering an increased power up to 633HP, a sport exhaust system, MHR Classical Wheel set available in sizes 20-inch front / 21-inch rear, and MHR Club sport coilover kit.
An additional power of 73HP and 100 Nm (74 lb-ft) just well-done fitted to the twin-turbo 4.4-liter V8 for a total output of 633HP and 780 Nm (575 lb-ft) of torque. Performance figures noted at 4.4 seconds of sprint time for 0 to 100 km/h, and top speed to 300 km/h. If you think it doesn’t make that big a difference with the original, we understand, yes it is. But relax, this is only the beginning session, as the tuner stated they are currently working on 670HP and 735HP packages with some tweaking on their turbochargers, downpipes and exhaust system. Just wait what the packages can do offer.
The wheels, the suspension kit, and also the sports exhaust system will be available from mid-April, while the 633HP MH5 S-Biturbo package from the end of April.
