Stonking: Hamann SLR Volcano

The lads over at aftermarket tuners Hamann have an insatiable appetite for kilowatts - not that there's a problem with that - and it seems not even a McLaren Mercedes-Benz SLR supercar with 467 kW can quench their thirst for insane power figures.

Hamann engineers have tweaked the 5.4-litre, supercharged V8 to deliver 515 kW and 830 Nm of torque courtesy of a newly programmed control unit, especially developed high performance exhaust manifolds and an amended belt pulley combination for the serial compressors. A second water pump and adjusted gearbox electronics also contributes to the increased performance. Needless to say, performance figures are absolutely 'volcanic' - try 0-100 km/h in just 3.6 seconds and a top speed of 348 km/h.
