I'm disappointed. Subaru said the WRX/STI was going to diverge from the Impreza. That is clearly not the case here. They had a great opportunity here and didn't take it. Even if they aren't ready to retire the EJ, putting it in a smaller, lightweight chassis would increase both performance and efficiency. But instead they stuck with a large, heavy chassis.
Frankly, I think Subaru would be better served with a turbo Impreza GT for those who want a practical "boost buggy" and a smaller, sportier WRX chassis with base and STI trims. That would renew Subaru's performance image, IMO.
