Forget emotion for a moment. If you were to base your next new car purchase purely on logic, what would it be? If you live in America, you most likely would buy either A) a V8-powered pickup or B) a fuel efficient hybrid. Why? Because either you need to move stuff around (pickup) or just yourself (hybrid). Yet for all their fuel-saving frugality, most hybrids don't pay back the extra cost spent on the technology very quickly.
Except perhaps one. A Canadian study of 16 different hybrids found that just one, the Mercedes Benz S400 Hybrid, cost less to own and run than its gasoline counterpart (that would be the regular S400). How is that so?
