Rather than tune the series naturally-aspirated 6.2-litre V8 engine, GAD implanted the twin-turbocharged 5.5-litre M157 V8 unit usually seen in the likes of the E 63 AMG, but things didn’t stop there.
A pair of upgraded turbochargers were fitted, along with remapped ECU software and an uprated cooling system, resulting in a monumental 625 kW (850 hp) and 1,350 Nm of torque. A revised 4MATIC all-wheel-drive system and MCT 7-speed transmission allows that power to be fully exploited, meaning 100 km/h arrives in just 3.1 seconds, 200 km/h in 8.7s and 300 km/h in 22.7s.
Chassis enhancements consist of a fully adjustable KW Suspension coilover kit and carbon ceramic brakes which bring this Coupe to a halt from 100 km/h in 33 metres and from 200 km/h in 132 metres.
Interested parties will need to check their bank account for €180,250 if they’d like the same conversion.
