Not that the Blue Oval's new six-cylinder musclecar needs more power. Yep, you read right: We called the new 3.7 Mustang a musclecar. Now if you're reeling from the idea of a Mustang V-6 ever being labeled with that word, or if you can't believe how far that meatball just flew from your mouth, chew on this: 0 to 60 in 5.1 seconds and the quarter mile in 13.7 at 102.0 mph. The Hemi-powered 376-horse Dodge Challenger R/T isn't any quicker to 60 and is just a tenth ahead at the quarter. Moreover, the new 3.7 is nearly as quick as last year's V-8-powered GT, which put down 4.9 and 13.5 at 104.2.
