Based on what Albeeno said, Dodge did the smartest thing-utilize a proven motor/transmission package, suspension parts, etc to build a new car that will predictably work and work well! I guess they could have tried sticking an inline 6 from a BMW in it to be different and show off a variety of engineering feats, but I think most Challenger buyers are going to buy this car based on a rock solid proven drivetrain, looks, and expected performance...besides, back in 1969 when the first E-bodies came out, they were built utilizing the chassis/suspension/drivetrains of the larger B-body Mopars...it worked then, and it will work now! It's the KISS method, utilizing what you have at hands for guaranteed results!
