RENNtech Mercedes-Benz CLS 63 AMG record quarter mile

 

In its factory form, the CLS 63 AMG is far from a weak performer. In the new ’63 AMG S’ form, it comes with a 5.5-litre twin-turbo V8 producing 430kW and 800Nm. It’s able to cover 0-100km/h in around 4.0 seconds.

In the hands of RENNtech, a German vehicle tuning specialist, the engine is given a liberal dose of steroids in the form of an upgraded turbo package, a modified engine computer, a custom exhaust system, and uprated intercooling. The beast then produces a whopping 540kW at the wheels.

With further help from an uprated limited-slip differential and drag radial tyres, the machine recently ran a quarter mile in just 10.6 seconds at 220km/h. According to the team behind the build, the time makes it the quickest CLS AMG 63 in the world. We don’t doubt them.
