Mclaren will launch its car tomorrow (Feb 1), and looks set to cause a legal battle with other teams and engineers.
It is thought that McLaren have concentrated on single lap pace, because:
"McGrath added that beating qualifying master Sebastian Vettel will be crucial if McLaren is to be successful in 2012, particularly as its analysis indicated that the raw pace of last year's MP4-26 was superior towards the end of the season despite Red Bull and Vettel's run of poles."
"He must be a brilliant driver, because by the end of last season we definitely had the best car and he was still whupping us," McGrath said.
"We're trying to figure out exactly what he's doing that's so good. How does he pull out that fast qualifying lap every time? We think it's driver skill. There's no trickery on the cars, he just gets more out of it than we do."
