AMG version of CLS revealed

Mercedes-Benz launches its new CLS 63 AMG at the LA Auto Show this week.

This is the Mercedes-Benz CLS 63 AMG, which the company says is 'all about... exciting design, ultimate performance and groundbreaking efficiency.'

Ahem, the Green Party might have something to say about that last claim, but the first two are about right, so let's get down to business.

Despite the numerical designation, the 63 is powered by a 5.5-litre twin-turbo V8 engine. It develops 525hp and 700Nm of torque, the latter at just 1,750rpm.

Those numbers improve on the old CLS AMG model by 10hp and 70Nm, and push the newcomer to 100km/h in just 4.4 seconds. However, there's also a Performance Pack option that raises power to 557hp and 800Nm. With that the sprint to 100km/h is cut by one tenth of a second.

Top speed is limited to 250km/h, though customers can pay to have it raised to 300km/h, for whatever reason. Power is sent to the rear wheels via a seven-speed MCT automatic gearbox.

AirMatic rear suspension is standard, there are steel springs at the front and it's lowered by 15mm compared to the standard CLS. The front track is wider and the arches filled with 19-inch rims.

There is something in Mercedes' efficiency protestations, too. The 63 AMG gets start-stop as standard, which contributes to economy and emissions figures rather more impressive than its predecessor's.

It now returns 9.9 litres/100km (28.5mpg) and emits 232g/km, compared to 14.6 litres/100km (19.4mpg) and 345g/km. Hardly a Nissan LEAF, but...

Following its world debut at this week's LA Auto Show, it goes on sale in 2011, with prices announced closer to that.
