Impressive showing by the M5 to hang with the Performance Package car as closely as it does and to edge it out slightly in elapsed time. The CLS is clearly pulling harder though with a trap of 121.7 versus the M5's 119.9. No surprise the GT-R easily beats both in the acceleration department. What we learn from this however is the Performance Package is faster albeit slightly so non-Performance Package cars are going to struggle against the M5. Impressive for the BMW with its smaller displacement and greater weight. The DCT is doing wonders for it.
Around the road course the M5 beats the CLS significantly with a lap of 1:24.89 to 1:26.30. The heavier M5 wins again. The GTR obviously crushes both with a time of 1:20.55.
