Well Tiff thinks it's quite good round the track but doesn't look all that fast on pick up.. it may be the fastest car top speed wise, it may even accelerate very well in a straight line, but it looks like it has oooodles of turbo lag which is really bad with a tight track similar to Top Gear's

Also thoose saying they are running out of ideas.. helping the RAF out PR wise and showing the fastest car in the world when they are not allowed to take it for a timed lap.. they kinda have thier hands tied to what they can do with it. But no doubt at some point it will get to go round the track..
