Most people don't really understand what 662 hp or 631 lb-ft of torque means. I like to explain it in terms of something many people seem to think is the epitome of high-performance. The BMW 335i turbo has 300 hp and 300 lb-ft of torque, and it's probably twice as fast as anything most people have driven. The GT500 has more than double those figures and weighs about the same. It will SCARE you silly.
