It's no secret that the people at AMG had their noses put out by the McLaren tie-up with Mercedes' previous flagship SLR supercar. This is its retort, the Mercedes-Benz SLS AMG, a 563bhp, near 200mph coupé. That's near because the SLS is limited to 197mph, the top speed undoubtedly more without the electronic killjoy reining in the v-max. Unsurprisingly, given it's an AMG project, the SLS is powered by AMG's naturally aspirated 6.2-litre V8, though in this range-topping machine it has been significantly reworked with a completely new intake manifold system, dry-sump lubrication, a strengthened crankcase, forged pistons and a freer breathing exhaust system.

The result on the road is a 0-62mph time of 3.8 seconds, the 6.2-litre V8 engine driving the rear wheels through a twin-clutch, paddle-shifted seven-speed automatic transmission. Much emphasis has been put on the car's weight, AMG building the SLS almost completely out of aluminium. That results in a kerb weight of 1,620kg, giving credence to AMG's claims that the SLS has agility to match its pace.

It certainly a looker too, the SLS unashamedly echoing the styling of the 1950's 300SL Gullwing. What is perhaps Mercedes' most iconic shape is brought right up to date with the SLS, the beetle-backed rump, the long bonnet and those very obvious gullwing doors giving it the look of its famous ancestor, though with a modern twist.

Unlike the '50's car the SLS is brimming with electronic driver aids. There are four drive mode choices for the transmission ranging from C (Controlled Efficiency) to M (Manual), taking in Sport and Sport+ on the way; the shifts speeding and becoming more aggressive as you move through the different settings. Similarly the ESP and traction control system offer differing levels of intervention, with on, Sport and off settings available. A limited slip differential comes as standard, while stopping power is taken care of by composite brakes on the front axle.

With its front-mid mounted V8 and transaxle layout the SLS should provide excellent balance and it rides on specially developed tyres specific to the car. As standard it comes comprehensively equipped, but AMG Performance Studio offers a number of enhancements including a performance chassis option, which allows additional tuning of the suspension; while lighter wheels, seats and a host of carbon trim elements are also offered. We've no doubt too if you ask nicely enough someone will remove the electronic top speed limiter. Prices have yet to be confirmed but expect a number getting close to £200,000 - and above if you go crazy with the options. We'll find out nearer its UK summer 2010 on sale date, though customers are likely to have an idea, as Mercedes dealers will already be taking orders.

The SLS will make its world debut at next week's Frankfurt Motor Show.
