The tuners at Speedriven are introducing their heavily modified Mercedes-Benz CL 600 which can unleash a mind-blowing 1,000 bhp.

It may look pretty much like a stock CL on the outside, but lurking underneath the familiar skin is a true beast as Speedriven has created what could turn out to be one of the fastest V12 cars out there with road-legal status. This is a 2003 model year CL 600 that comes with twice the power of the standard car as the 5.5-liter twin-turbo V12 has been thoroughly upgraded and it’s now capable of developing a monstrous 1,000 bhp (746 kW). This was achieved by installing larger Garrett turbochargers, a new exhaust manifold along with a bespoke air intake and intercooler.

The motor is now compatible with ethanol and the V12’s peak output (at the crank) was achieved when using Ignite Racing high-performance ethanol. It runs the quarter mile in less than eleven seconds, but there’s no word regarding the 0-60 mph (0-96 km/h) time although it’s safe to assume it takes a lot less than the 4.7 seconds needed by the standard CL 600.

Interestingly, the car still has the factory Mercedes-Benz ECU, but obviously it was updated with Speedriven’s specially developed software necessary now that the car has gone through so many changes in the engine compartment.
