It seems almost everyone in the thread is missing the guys point.

He's just asking why a heavier, less powerful production based car isnt that much slower around the track

He isnt remotely suggesting Andy's car is slow, because it is a bloody rocket.

But more power doesnt always mean you'll go faster around a track. And lets face it, modern Porsches in any race series are superbly fettled for that purpose so will always be very very fast around race tracks.

But as others said, the faster you get around a track, the harder it is to knock 1 second off...or even 0.5 seconds...or even 0.1 secs.
So if Andy's car is a clear 2 secs ahead, that is massive over an already very fast car.
