Depends on the model. The models that matter (the V8 ones) are the R/T (375hp) and the SRT8 (425hp).
2009-10 - 250 hp, 2011-present - 305 hp
2009-10 - 250 hp, 2011-present - 305 hp.
The 2009 Dodge Challenger's engine produces 250 hp @ 6400 rpm.
2009-10 250 hp, 2011 305 hp
Depends on what engine a 1972 dodge challenger has...
the 2009 is much heavier as they never built a challenger until 1970.
Depends on which Challenger model you're referring to (SXT, R/T, SRT)...
The 2009 Dodge Challenger's engine produces 250 ft-lbs. @ 3800 rpm.
425
With Diablo predator installed it has 525 HP
The G8 has 365hp and the Challenger R/T has 375hp but the Challenger weighs a little more than the G8 so it would be a tight race. But if it was the 425hp Challenger SRT8, it would kill the G8
