GT:
Guys the rumour is that it did 4 seconds (yes 4 SECONDS) better lap time around the top gear track than the 458. IF this is true and we are compared dry vs dry times with similar tires then this car is a game changer..
The similarly looking Ascari KZ1 clocked a laptime almost 2 seconds faster than the Ferrari's in 2007, after four years of evolution that the least you would expect.
That said, you have to reckon they are quite good at building hype. In F1 despite having just won one title in the XXI century (and that was the year after having been involved in a spy scandal) they have somehow managed to convince some people they are kind of the most technical and professional team in the sport.
Now, having been releasing (without actyually releasing it) a car for like two, threee years, having the chance to benchmark the new Ferrari for probably more than a year....if it wasn't able of trouncing its rivals someone should be fired at McLaren.
And regarding built quality you don't see if a car it's actually well built testing press cars (which are 'special units') at the official launch of a model. That should be judged after the car has been on the road for a few years. Was the McLaren-built SLR especially well thrown together?
