Brabus has introduced a new tuning program for the 2013 Mercedes SL-Class. Starting with the exterior, the model can be outfitted with a body kit that includes new bumpers, revised side skirts, front fender vents and a trunk-mounted spoiler. Customers can also order a sports exhaust system and Monoblock wheels that are available in sizes ranging from 18- to 20-inches. To spruce up the cabin, Brabus offers premium leather upholstery, illuminated sill plates, wood / carbon fiber trim and a new speedometer that tops out at 320 km/h or 360 km/h (200 mph or 225 mph). The SL500 (aka 550) can be equipped with a 520 PowerXtra CGI power kit which enables the twin-turbo 4.7-liter V8 engine to produce 520 PS (382 kW / 512 hp) and 820 Nm (604 lb-ft) of torque. This allows the convertible to accelerate from 0-100 km/h in 4.4 seconds, before hitting an electronically-limited top speed of 250, 275 or 300 km/h (155, 172, 186 mph). The car can also be equipped with a limited-slip differential and a revised suspension with sport springs (on the SL 350) or a reprogrammed ABC (Active Body Control) module that reduces the ride height by approximately 25mm.
