Posted from an proven insider at an german forum !!!
FAKTS:
3.3ltr.V6.
3.296ccm
3-way-charging ... my guess BiTurbo with eTurbo-System
Power output 430hp (on the paper) 450+hp for real (german hp!)
Torque 580Nm
Redline 7.800U/min
EU-Weight: 1483 kg (F80)
There are strange rumors that the leaked "S55" 3.0ltr.I6 with 415hp was an misinformation campaign special for internet forums.
