Starting with the 63 AMG Black Series is a great way to attempt world records. The factory model is highly strung as is, with plenty of racing parts and high-strength components ready to produce big power, all day long.

The Californian-based company is calling this particular version the fastest and quickest Mercedes-Benz in the world. We take it they mean road-legal CLK. It recently ran a quarter mile in just 9.16 seconds at 241km/h, which sure sounds like a record to us.

Under the bonnet the factory 6.2-litre naturally aspirated V8 receives a twin-screw supercharger system as well as engine computer modifications, a custom exhaust, and plenty of other tasty upgrades. As a result, the mighty Merc produces 755kW and 1356Nm.
