RE: Why the 6.1L Challenger could be faster than the GT500
One thing to keep in mind when using the Jeep SRT-8 as a basis for comparison is that it has all-wheel drive, so it can launch much harder from a stop. This gives a big advantage in 0-60 times. On the Challenger, some of the low end grunt of the 6.1 may be translated into a cloud of smoke at the starting line. Dodge still estimates 4.5 to 60 for the Challenger concept, so the reduced weight may offset the awd advantage.
