AC Schnitzer has released the first teaser photos of the ACS5 Sport, ahead of its debut at the Geneva Motor Show.

Based on the BMW M5, the model features a twin-turbo 4.4-liter V8 engine which has been tuned to produce 620 PS (456 kW / 612 hp) and 720 Nm (531 lb-ft) of torque. This is a little less than the G-Power M5, but still an increase of 60 PS (44 kW / 59 hp) and 40 Nm (30 lb-ft).

Interior changes appear limited, but apparently include blue-accented trim, an alloy iDrive cap and stainless steel pedals.
