The diffuser doesnt actually create negative pressure though, the high speed air passing under the car creates that (high velocity flow = low pressure, low velocity flow = high pressure in accordance with bernouli's theorem). The low height of the floor relative to the ground basically forces the air to a high velocity creating the low pressure zone. The actual (low) pressure peak is found at the mouth of the diffuser (at the front of the diffuser) and the air below the car is generally below ambient pressure so the whole floor creates downforce. The diffuser serves to assist pressure recovery or the matching of the velocities of the flows where they meet at the back of the car.

Nice explanation.

Now then...who's been following the Jerez testing...

FASTEST TIMES, DAY THREE TESTING, JEREZ
1 Nico Rosberg (Ger) Mercedes 1:17.613*
2 Romain Grosjean (Swi) Lotus 1:18.419
3 Sebastian Vettel (Ger) Red Bull-Renault 1:19.297
4 Lewis Hamilton (GB) McLaren-Mercedes 1:19.464

New driver, Hellooooo

Testing shows nothing, it would be nice to see Lotus building a good car but remember last years testing when the sauber was fastest to try and gain sponsorship

getting closer now.. been keeping half an eye on the testing, as usual its all over the place.

is it going to be red bull domination again do we think?

Almost every driver at some point has 'set the pace' lol. Hope its not another Redbull show...

My friend works for Red Bull - he does some of the electrics on Seb's car. I get the impression they're pretty pleased with the car at the moment. However, that could be the standard smoke and mirrors that most F1 teams use so take that with a massive pinch of salt.

I probably wouldn't bet against them though.

I don't think many people will be 

Speaking of betting, does anyone regularly have a punt on individual races or the season. Can you even make bets on say 1/2/3 correct placing? I bet on football but I'v never spared a though for F1...
