"Want more M5 references? The Pontiac is an inch and a pound larger in every direction, but nips the BMW in most performance categories. The previous-gen M5 ran 0-to-60 in 4.5 seconds; the manual trans G8 GXPs match that. The Bimmer grips to 0.84 g on the skidpad, the Pontiacs stick to 0.88-0.90 g. The BMW stops from 60-0 in 116 feet, the Pontiacs from 111-117. This is all the more impressive given the M5's near 200-pound weight advantage. Sure, the premium German performance kings have moved on from that previous-gen M5, but look what they cost. Before we forget, the LS3 sounds magnificent too; deep at idle, all pops and burbles on the overrun, yet never over the top."
