The Brabus SV12 R, a 211mph version of the Mercedes S-class, is set to make its debut at the Frankfurt motor show.
The car is fitted with a twin-turbocharged V12, which swells from 5.5 to 6.3 litres and gains a new crankshaft, forged pistons, larger turbochargers, a new ECU and a stainless steel exhaust. The car now produces 740bhp and torque is electronically limited to 811lb ft.
The SV12 R will crack 62mph in 4.0sec, 0-124mph takes 11.9sec and the top speed is electronically limited to 211mph.
A high-performance braking system provides stopping power via 12-piston calipers at the front and six-cylinder items on the back. The set-up is 380x36mm vented and cross-drilled discs up front, and 355x28mm discs at the rear.
The styling has been beefed up too, with an aggressive front spoiler that reduces lift and improves cooling. At the back there's a boot-mounted spoiler and deeper bumper. Prices have yet to be announced.
