I got picked up at Cologne Airport last year in an A8 4.2 TDi. I coaxed the (Irish) chauffeur into giving it some welly and man did the thing shift. However it is an ugly car, on the outside.What engine options does this car have? Is there any non-SUV Audi coming out that has the 4.2 liter TDI engine? Except for the ugly-ish A8...?
