All that power is transferred to the rear wheels through a modified five-speed automatic transmission while buyers can also opt for a BRABUS locking differential.
Acceleration from standstill to 100 km/h (62mph) comes after 4.0 seconds, 200 km/h (124 mph) after only 11.9 seconds while the saloon's maximum speed is electronically limited to 340km/h or 211 mph.
The Brabus SV12R rides on 21-inch alloy wheels (available in various designs) wrapped in Pirelli or YOKOHAMA tires in size 265/30 ZR 21 up front and 295/30 ZR 21 on the rear axle.
The beefed up S600 also gets a high-performance brake system with 12-piston aluminum fixed calipers and 380 x 36-mm (15.0 x 1.42 inches) vented and cross-drilled discs at the front, and 355 x 28-mm (14.0 x 1.1 inches) discs and six-piston aluminum fixed calipers on the rear axle along with sportier suspension set-up.
Being a Brabus and all, the SV12 R receives a cosmetic upgrade with a new bodykit that includes a new front bumper with integrated LED lights, side skirts, a discreet boot lid spoiler, a new rear diffuser that also houses the quad tailpipes and side air vents.
Interior enhancements include a newly created BRABUS Yachting trim that blends maple and tropical Wenge wood and a full leather treatment in a combination of light-beige and dark-brown leather.
The Brabus SV12 R will make its world debut at next week's Frankfurt motorshow.
