Brabus has taken the wraps off its latest mega-Mercedes with the introduction of the CL-based SV12 S Biturbo Coupe. Taking a donor Mercedes-Benz CL600 as their starting point, engineers then got to work on turning the standard car into what its makers claim is the world's fastest and most powerful coupe. Final output is a significant 730hp (537 kW) and 1,320 Nm of torque, which should allow the tuned CL to reach a top speed of 340km/h.

To achieve the status of the ‘most powerful street-legal V12 engine in the world’, engineers had to install a unique crankshaft with a longer stroke, increase the cylinder bore and add new forged pistons, precision-machine the cylinder heads and finally, fit them with four special camshafts.

Attention was then turned to the engine’s peripherals with the addition of new exhaust manifolds, high-flow turbochargers and intercooler, and a performance exhaust system with metal catalysts and low back pressure.

Power is transferred to the rear wheels via a modified five-speed automatic transmission and Brabus also offers an optional locking differential for better traction. The 0-100km/h dash takes just four seconds, with 200km/h passing in 11.9.
