Some nice info here, although I thought his answer on the 6.1 "looking back is not very constructive..." was a bit misplaced. If you don't evaluate what was good and bad about your previous product, how can you expect to make something better? And given how retro the Challenger is, it's a ridiculous statement to make in general.
I like how he had the balls to say 'nitrous' when asked about cheap power adders. Makes sense given the budget proposed in the question, just not what I'd expect from the company rep.
