The other two cars are there for context exactly as they should be to put the GT3's performance in perspective. So how does the GT3 stack up?
The McLaren lapped their test track at 1:02.7 hitting a peak of 151.7 miles per hour. EVO shares the information that with the Pagani Huayra they hit a 1:02.4 so the McLaren is stupid quick, epic quick, around the track.
The GT3 incredibly beats the MP4-12C by a tenth of a second. That is stunning and it is difficult to use words to express just how impressive of a feat it is. 1:02.6 for the GT3 with a lower top speed hit of 144.6 so the GT3 is doing it with its handling, balances, and brakes, not power. Also, stickier rubber plays a big role here as the GT3 comes with R-Compound rubber. Would the McLaren gain back its tenth and then some with equal rubber? More than likely.
Unfortunately, EVO does not do a direct lap comparison including the Nissan GTR only a subjective comparison on backroads. That's cool and all but this network prefers hard data to subjective points. Ideally one should include both.
Still, a great comparison video. Enjoy it below:
