i just realized the R uses a 6 liter V12, and the F uses a 7.3 liter V12. could anyone explain that?
edit: i think i figured it out. THe F and the R use different engines. The R uses a version of the CLK GTR's engine, while the F uses the more mainstream 7.3L AMG V12.
edit2: i've confused myself more. The 6L V12 is the BiTurbo engine... but i don't think its boosted in this application?
ok ok ok.
all zonda's use the M120 engine, which has been produced in variations from 6.0L to 7.3L. The zonda R does use the 6.0L found in the CLK GTR, albeit a modernized version. The 6.0L runs a higher redline, higher compression, and (obviously) smaller pistons than the 7.3L, allowing it to rev much more quickly.
