German tuner AC Schnitzer begins promoting their upcoming ACS5 model

Through its social media channels, AC Schnitzer offers a glance at the upcoming, BMW M5-based, ACS 5 that will produce 620 horsepower. The super potent model will be introduced at the next week’s Geneva Motor Show and it is being advertised a successor of the current ACS5 Sport based on the BMW 550i.

The “standard” F10 BMW M5 uses a high-revving 4.4-liter (4395cc) turbocharged engine with 560 horsepower from 5,750-7,000 rpm and 502 lb-ft of torque from only 1500rpm. AC Schnitzer has yet to reveal what the torque increase might be.
