First thing I can tell you is... the Red Bull looked a LOT better today. So clean into the chicane, Webber was braking a good 20 metres later than most, and retaining good mid-corner speed to boot. Exhaust note was still very EBD-ish. McLaren was probably next best looking. Not quite the braking stability of Red Bull, but always super clean into corners and they held a similar mid-corner speed to RB, with similar levels of traction too.
The Caterham continues to impress me, probably because it's looking so much better than the T128, but it's good on traction, good in the bends and good on braking. I can see this car scoring double digit points (overall) this season.
The Ferrari is still looking pretty poor to me, regardless of what programme the team are running it looks poor in the bends, understeery, slow out of bends and just not well balanced.
