Mansory has built a 1,000bhp S-Class

One thousand horsepower. More than a LaFerrari. More than a Porsche 918. More than a McLaren P1. This ‘heavily modified' Mercedes-Benz S63 AMG produces a cool, clean 1,000bhp. Thanks, Mansory.

The infamous German tuning firm, notable for its USPs of subtlety, grace and dignity (wait, we might have got that wrong), has deemed it prudent to turn a new S63 AMG Mercedes - not a car, with 585bhp as standard, we'd ever considered slow, exactly - into luxury transport befitting the most intimidating, time-pressed of dictators.

So there's the option of an 'M800' pack with a paltry 800bhp and 885lb ft of torque available between the bomb-like window of 1,700rpm and 3,500rpm. Buy this, and together with a ‘throaty and imposing' sports exhaust, you'll be able to sprint from 0-62mph in just 3.6 seconds.

But that's for wimps. What you really want is the 'M1000' performance kit. This gives you new connecting rods, big end bearings, a new crankshaft, bearing bushings, a new turbo, suction and compressor system, as well as many other bits.

Mansory has also fabricated a new pipe fan manifold, so instead of the ‘standard' S63's puny 585bhp, you now get that aforementioned 1,000bhp and a whopping 1,032lb ft of torque. 0-62mph? 3.2 seconds. Top speed? A ‘limited' 186mph.

There are some exterior and interior appointments, too, but we suspect you won't notice these, y'know, because of the ONE THOUSAND HORSEPOWER.
