Apart from the skinny rear wings, I actually like the new shape, especially the straight nose. Mind you, the Renault looks horrendous, but that's partly because of the vile colour scheme. Even before all the issues with Ferrari's exhausts, they were worried that they'd struggle this season moreso than in recent years. BMW are seemingly furthest ahead in terms of development, being as they were the first team to have a working KERS system running on the car.
In terms of Donington, i'm pretty willing to give it a chance actually. Silverstone is dull as hell to watch at, Donington's much better, and the best part of the track is clearly the Craners anyway. The new section, especially the infield loop, should be pretty good though, because that loop will be one big downhill sweep, because that section of the infield is on a hill. I think it should be quite cool. It does need widening though, they've announced they'll be doing that. They're already busy building stuff, and the new pit buildings should be constructed by mid this year.
