Cars, Engines Valves and Se

If you were to compare the two - UK born cars and US born cars - which do you think would be most likely to win - you may have to choose a range of playing fields to compare fairly - but say you had a “fastest”, a “most economic”, a “lightest car”, a “least poluting” etc. which would you think claimed the victory out of the top ten for each category? Cars in the uk tend to be more german influenced than american cars, or automobiles - but is that a good thing - does a twin turbo lean AMG, Merc or audi lump really trump a big old american lump on the above? I would bet so but you would have to check?
