M157 - RS 850 & RS 850+

The RS850 is a true wolf in sheep\s clothing. On one hand, it does impress with brute power of 850HP and 1300Nm, while on the other hand it still maintains it's suitability for everyday use. This conversion is possible in two- and four-wheel driven vehicles. The increase in power by up to 62% is achieved by upgrade turbochargers, which are based on the original Garrett chargers. By modifying the compressor wheel and the turbine exhaust, a lower backpressure and a higher compression ratio is achieved. Thus, the maximum boost pressure can be maintained almost throughout the entire speed range. In addition, the entire exhaust system from the turbocharger up to the middle silencer is replaced by a 3-inch system with 200CPI racing cats. Optionally, the back-end of the exhaust system can also be completely replaced by a system with valve control. Furthermore, this upgrade includes an electronic and mechanical gearbox reinforcement, racing-sport limited-slip differentials on all drive axes and the optimization of the air-intake. Also necessary is the upgrade of the charge air cooling, racing spark plugs and of course the fine-tuning of the engine electronics. Optionally available for purchase is an extended speedometer, with a display range of up to 380 km/h. The (E63) RS850 accelerates with all-wheel drive from 0 to 100 km/h in 2.9 seconds and achieves a theoretical top speed of 360km/h which is however electronically limited to 345 km/h.

The Plus-Model of the RS850 series can reach up to a maximum of 1020HP and 1400Nm. Built on the basis of the established RS850, the technology is individually upgraded even further, based on the requirements and wishes of the customer. The upgrade affects all previously optimized areas and leads to this incredible increase in performance by up to 94%.
