Seriously: How are they doing compared to European cars with less V and less Liters...say an Audi A4 2,2 Liter or any other European car with 1,8-2,5l and under 200/230hp..I am asking because I somehow get the impression that the american cars with their big engines (they all seem to start at 3,5L and with V6 and more than 250hp while european cars start at 1,6 or 1,8L and around 100hp) are not as efficient as euro ones...am I totally wrong or how is it? And I am not talking about fuel efficiency, but about performance. If they are equal, why don't the US manufacturers start building smaller, yet sufficent in terms of performance for the car, engines which consume less fuel so the people who want to save on fuel don't need to buy asian or euro...I really don't know anything about US cars so I could be totally of the track here.
