Guaranteed carefree driving pleasure
The tuning experts at AC Schnitzer offer even more driving pleasure with a wealth of performance upgrades for BMW vehicles. From the 1-series to the 7-series BMW, and for all models of the X-series, the M-Power models and the Z4, so far many upgrades have been developed to help engines "on their way" with an extra 27 to 93 HP.

Engine tuning and performance upgrades have a long tradition at AC Schnitzer. With years of experience and sound engineering knowledge, we assess all parameters relevant for performance and test the engines in complex structured, simulated driving tests with long-term loads on their in-house roller test bed, on the test track and under everyday conditions in road traffic. Development is focussed on targeted performance upgrades by detecting all relevant engine data, significantly improving acceleration and flexibility with an optimised response behaviour of the BMW vehicles.

Because at AC Schnitzer, not only driving pleasure but also the safety aspect is an essential element of company philosophy, all products are developed following a quality control system (to DIN ISO 9001:2008) and are homologated (to § 19 StVZO – state-specific).

An additional engine control unit which, thanks to "Plug-and-Play“ technology, can be installed and activated quickly, works in parallel with the original ECU and ensures carefree driving. The intelligent control electronics detect all relevant engine data and increase power and torque in a targeted fashion.

The software database is constantly brought up to date by experts and has the facility for online programming, diagnosis and update (petrol models). For even more safety, all standard engine protection functions are monitored: the AC Schnitzer performance upgrade only switches on under optimum engine conditions. In the event of irregularities, the efficient performance unit switches off to prevent overloading the engine and powertrain.

At AC Schnitzer, more engine power means more driving pleasure without a guilty conscience towards the environment. Because in almost all engines, the standard consumption and CO2 emissions remain unchanged as a result of the efficiency gain. The increase in power even improves the CO2 figure per HP and the optimised engine efficiency also allows fuel savings.

For even more carefree driving, there is the two-year warranty from AC Schnitzer. From the date of first registration up to a total kilometrage of 100,000 km (for M-Power vehicles, two years up to a total kilometrage of 60,000 km), the Aachen-based company offers a warranty on all components excluded from the BMW warranty. In addition, there is the option of a warranty extension for the third year. Choosing AC Schnitzer means you're guaranteed to sit happily back in your seat - without a guilty conscience or unpleasant surprises!
