Richard,
official 0-62 mph for the S1 is faster than the 3.7l. 5s vs 5.5s caused I imagine by the gearbox on the 3.7l.
But once on the move the 3.7l is faster.
Top speed wise the 3.7l wins at 140 mph vs 134 mph.
The big difference is the torque of 280 lb/ft @ 4,500 rpm for the 3.7 vs 206 lb/ft @ 4,900 rpm which makes the 3.7l so much fun in 3rd.
