Well, nearly 800bhp – that's what the upgrades to the Mercedes-AMG SL63 from G-Power deliver.

German tuners, G-Power, have wrung another 200-odd horsepower, now up to 789bhp, and an exceptional 811lb ft of torque from the already powerful Mercedes-AMG SL63. Which, for a luxury convertible roadster, is rather a lot.

What they've done is modify the Merc's twin turbochargers by adding larger turbine and compressor wheels. They also fiddled with the compressor turbine blades which reduces exhaust back-pressure and gas temperature and increases the in-air flow rate – and finished off with a healthy dose of software changes.

There's is also an all-new stainless steel exhaust system including downpipes and sports catalysts which give the engine bigger lungs and a louder voice. Which, you know, the AMG so desperately needs.

G-Power reckons their SL63 is 0.6 seconds quicker than the standard car from 0-60mph, doing it in a knuckle-biting 4.1 seconds and, now that they've removed the factory speed limiter, it'll fly on to 211mph. That's supercar territory.

To help the car actually grip the tarmac, high-performance rubber to the tune of 265/30 ZR21 up front and 295/30 ZR21 at the rear wrap neatly over shiny new 21-inch forged aluminium diamond-cut wheels.

Prices are yet to be released but, considering these performance figures are better than that of their German rival, the new 522bhp BMW 850i Convertible, it's not far-fetched to see current Mercedes-AMG SL63 considering this upgrade... bragging rights, right?
