LA Auto Show: 2012 Mercedes-Benz CLS63 AMG

News

Mercedes unveils its new 518 hp CLS63 AMG, powered by a new 5.5 liter biturbo V8.

The realm of overpowered German four-doors has a new king, and it's called the Mercedes-Benz CLS63 AMG. The 2012 model will be powered by AMG's new M157 5.5 liter biturbo V8 which will kick out 518 hp and a monstrous 516lb ft of torque. Opting for the AMG Performance Package raises boost pressure from 14.5 to 18.8 psi which results in an additional 32 hp and a very useful 74lb ft of torque. 

The engine is mated to AMG's excellent MCT seven speed automatic transmission. With the Performance Pack option, this will scoot the CLS63 from 0-60 in 4.3 seconds and on to a top speed of 186 mph. Without the Performance Pack, the fun stops at the usual 155 mph.

All this power is put to the ground by 285 section rear tires on 19 inch wheels. The fronts are 255 R19s and are accommodated by an increase in front bodywork width of nearly an inch. AMG's independent adaptive suspension, electronic damping and three stage traction control come standard. The vast brake discs measure 14.2 inches in diameter and are clamped by AMG's trademark cinderblock-sized calipers.  

The original CLS AMG was one of the first cars that was able to stand shoulder to shoulder with its high performance counterparts at BMW. Here's hoping the battle will continue to rage on.
