Ahead of its Geneva debut, Aachen-based tuner AC Schnitzer reveals the ACS5 model based on the new F10 BMW M5. As we reported yesterday, the super sporty and tuned up sedan gets a significant power upgrade from the standard 560 hp and 502 lb-ft of torque to 620 hp and 582 lb-ft.

The exhaust sound is enhanced via AC Schnitzer twin sports silencer with valve control.

As all previous AC Schnitzer upgrades, the M5 gets a new suspension spring kit and specially designed wheels, Type VIII in 21 inch and Type V and IV in 20 inch.

ACS5 features plenty of carbon fiber parts, starting with the front spoiler and rear diffusor. Other visual upgrades come via the chrome grille and roof spoiler.

The interior of the ACS5 has been upgraded as well with carbon fiber trim and blue accents that match the Magic Blue exterior color.

Pricing for the total package will be announced next week at the 2012 Geneva Motor Show.
