German tuning company Brabus regularly produces tweaked Mercedes-Benz AMG cars with extra horsepower and outlandish body parts, and the Geneva show continued that tradition. The tuner used the show to reveal five tweaked AMG products, so of which have as much as 788 hp.
The first tuned model is the Brabus 800 Roadster, based on the Mercedes SL65 AMG. By virtue of new turbochargers, new intercoolers, a new stainless-steel exhaust, and a reprogrammed engine computer, the car's 6.0-liter V-12 engine now cranks 788 hp and 1047 lb-ft of torque. Brabus says that's enough for a 3.7-second 0-to-62-mph sprint and an electronically limited top speed of 217 mph.
Other upgrades include a new carbon-fiber bodykit designed to reduce lift at speed, a locking rear differential, 20-inch forged wheels, unique leather and Alcantara upholstery, and a reprogrammed computer that makes the air suspension ride 1.0 inch lower than stock.
Brabus also worked its magic on the CLS63 AMG, modifying the 5.5-liter twin-turbo V-8 to produce 720 hp and 785 lb-ft. That power boost is courtesy of new turbochargers, an additional intercooler, gold-plated intake tubes to reduce heat, larger catalytic converters, and a larger exhaust. The upgrade is offered for both the standard CLS63 AMG four-door and its shooting brake variant. Brabus claims cars so equipped can hit 62 mph in 3.8 seconds and top speed is, again, limited to 217 mph.
As with the 800 Roadster, Brabus also endows the CLS63 with a carbon-fiber bodykit, 20-inch wheels, new leather and Alcantara interior bits, and a 250-mph speedometer.
Just in case the off-road-capable G65 AMG didn't already seem excessive enough, Brabus has also tweaked it. New turbochargers, intercoolers, air boxes, and exhausts, plus a retuned computer, permit the 6.0-liter V-12 engine to offer the same 788 hp and 1047 lb-ft as the 800 Roadster. The four-wheel-drive SUV can reportedly hit 62 mph in 4.2 seconds and its top speed is limited to 155 mph -- although Brabus claims the Widestar is powerful enough to reach 168 mph.
The Widestar name means the G65 AMG's body has been stretched, by virtue of big fender flares that add 4.7 inches of width. The running boards now have LED illumination, and 23-inch wheels come standard. Also included is an updated suspension with Bilstein components and a two-way adaptive setting. Leather, Alcantara, wood, and carbon-fiber interior trim round out the changes.
This kit can be applied to either the GL63 AMG or ML63 AMG SUVs, with identical results. A new sports exhaust and an add-on engine computer boost the 5.5-liter twin-turbo V-8 engine to 611 hp and 604 lb-ft, enough to allow the ML63 hit 62 mph in 4.5 seconds and the GL63 reach the benchmark in 4.7 seconds.
Both cars get the Widestar treatment, increasing the width of the ML63 AMG by 2.5 inches and the GL63 AMG by 3.1 inches. The former has 22-inch wheels and latter 23-inch wheels
