Fastest-ever Mercedes-Benz SLK has 415bhp, 398lb ft
21 August 2011

Mercedes-Benz has revealed its most powerful SLK ever, the Mercedes SLK55 AMG.

The 155mph machine has a naturally aspirated AMG 5.5-litre V8 engine that boasts 415bhp (almost 60bhp more than its predecessor), 398lb ft of torque and a 0-60mph time of 4.5sec.

The roadster has an AMG Speedshift Plus 7G-Tronic automatic transmission that features three modes – sport, manual and 'controlled efficiency'. It features AMG performance components including sports suspension with a Direct-Steer system that enhances handling and agility, Torque Vectoring Brakes that provide selective brake actuation at the rear wheel during cornering and a high-performance braking system.

An optional AMG Handling Package comprises sportier suspension with stiffer tuning, an AMG rear axle differential lock, two-piece brake discs at the front and a three-spoke AMG Performance steering wheel finished in premium leather with Alcantara grip inserts.

The front apron of the roadster features large air inlets and AMG-specific LED daytime running lights, while the wide radiator grille is a nod to the SLS AMG sports car. The SLK55 AMG also boasts styling tweaks including light-alloy wheels, body styling with spoiler lip and two chrome-plated twin tailpipes at the rear.

Darkened clear-lens headlamps and darkened bicolor tail lamps come as standard exclusively on the top-of-the-range V8 model. Bi-Xenon headlights with Active Curve Illumination are also available as an optional extra.

The interior design of the SLK55 AMG is reminiscent of the SLS, with four jet-engine style air vents and the centre console finished in brushed aluminium. The car features an AMG Performance steering wheel plus sports seats with the Airscarf neck-level heating system.

The standard retractable hardtop opens and closes in less than 20 seconds. Two other roof variants are available, including one with the Magic Sky Control system, which has glass that can switch from light to dark at the press of a button.

Instead of a standard wind-stop, the car has a new Airguide system. It consists of pivoting transparent plastic wings which are attached to the back of the roll-over bars, meaning no installation or removal is required.

The third generation of the AMG roadster model will be on display at the Frankfurt motor show next month and will go on sale early next year.
