I believe that the Q2 is so much cheaper than the ATB that only a person who is after doing the best lap times in a racetrack would even consider going for the latter. Or if there are doubts about the Q2's ability to cope with a seriously modified engine (e.g. oversized to 3700cc, supercharged or both) that would get him to go for a maybe custom-made ATB, provided of course that Quaife will offer him the same lifetime warranty they offer for stock V6s.
