DRAG RACE
There’s just nothing quite like the visceral thrill of tromping on the accelerator of a
Mopar-powered quarter-mile monster and being slammed back into your seat after
you chop down the Christmas Tree. Mopar’s got a full array of how-to books
and a vicious stable of hungry “A” Engine and Hemi horses to take you on an
unforgettable trip.
