Litreage, i like it! The Rx's are all ****els (if that gets past the censor) and work differently. Agree on the big "muscle" cars, totally under engineered just because they think bigger is better. They should give one of their engines to the japanese, get genuine BIG hp then. Mind you, there is that 2000hp mustang on you tube, but it has got a house-sized turbo on it.
