ist ja doch noch mehr PS geplannt... 504 bzw. 536 klingt schon besser... mit einem Chip dann irgendwann mal 600 PS (wäre ja "nur" 100 PS/1000 cm3)

"At time of press, engine modifications have been limited to an additional 450cc of displacement, mild porting of cylinder heads and larger valves, but the most important gains are to be found in lightened internal components as well as re-mapping of the S70/4's direct injection and Double VANOS variable valve timing mechanism. BMW's head of engine development, Paul Rosche, is confident that final output figures will easily surpass the 376 kW (504 bhp) of the prototype vehicle tested at Nurburgring in December.
"The possibilities of the new Bosch engine management system combined with BMW's revolutionary direct injection system and Valvetronic intake control are limitless. In conjunction with the existing electronic throttle and and iDrive systems, we hope our customers will be able to fully exploit this vehicle's power to the fullest. Our target is currently 500 kW (536 HP), which we should easily reach within a few months time," said Professor Rosche."
