Mercedes-AMG will officially launch tomorrow, at the Geneva Motor Show, the new and eagerly-awaited V8 unit.

The grumpy powerplant, among other technologies used, showcases direct injection and twin-turbocharging, thus rising the performance figures to impressive numbers:

- 544 HP or 571 HP(Performance Package) max. output/5500 rpm
- 800 Nm/2000-4500 rpm or 900 Nm/2500-3750 rpm max. torque
- 4,5 sec/4,4 sec up to 100 km/h
- max. speed:250/300 km/h - electronically limited
- 204 kg max. weight (dry)

The new engine will be offered, at first, for the S 63 AMG, which will most likely receive the S 55 AMG name.

A detailed official press release will be issued tomorrow, along with the already famous press kit for the Geneva Motor Show 2010.
