In the latest EVO Magazine, with 200mph a club on the front, in one section called speed addicts, Gordon Murray tells of his experiences with the xp3, he says " the car has a slight advantage over all the other f1's, its a little faster than all of them". He also says this is because it is lighter than all f1's, its older engine makes it faster (i didn't get this), and it has more horsepower (660 rather than the normal 627).
It also says his experiences racing young hopefuls in m3's on the open road highway in Belgium, quite a funny story. Guess who wins.
Just thought u enthusiasts might like to know, when I first saw it I thought it was not true, but then its the designer we are talking about here. Anyway hope everyone enjoys the info,
