I like how nobody was arguing anymore but the classic import vs. domestic debate still fumes within you. Read the article yourself, as Motortrend didn't jump and spin things as you or the the GTR Forums guy did. They said they simply believe it makes more than 507hp according to their dyno tests and energy consumption calculations. Either way, that's STILL a worse power-to-weight ratio than the ZR1 with almost dead-even performance. I'd also like to see how they compare in wet, icy and off-road conditions...
Whatever you are trying to win, it is apparent you're biased.
