F1 » Red Bull reveals new RB8


@Capi , The air flowing under the car is as important as the air flowing over the car. The diffuser or floor is designed to ensure the smoothest exit for the air flowing under the car. The quicker the air exits the more downforce the car generates. For this to work the chassis has to be as high as possible. So over the past few years the noses of F1 cars have become higher and higher. For safety it was decided this year to introduce a maximum height for the nose. The rulemakers however left the maximum height of the front of the chassis as before. Therefore to maximize airflow under the car you need a 75mm step between the bulkhead and the nose. The gain in this is much more than the loss by inefficient aero over the step.

F1 » Technical director leaves HRT


This is F1 !!! Teams like HRT , Marussia and even Merc GP that don't have a car to run in the first test need to wake up. Here we are complaining about limited testing and with about 5 weeks to go to the first GP and these teams don't have a car yet. I know that testing is optional but surely you need to make the most of it !!!

F1 » Sauber C31 breaks cover


@arcuid , Merc GP haven't even got a car yet so I have little faith for them this year. There 2010 car was too short ... so their solution was to build a shorter car for 2011 ... Maybe they are waiting to see this Newey car and now they will build a car with a 'step and a duct' ... Here's hoping they pull a rabbit out of a hat ... Schumi needs a good car !!!

F1 » Lotus launches new E20


@Marc, There is a distinct step between the front of the chassis and the nose. Over the last few years the nose of F1 cars has become higher and higher to the point where it is a safety issue. Therefore this years rules reduce the maximum height of the nose. The rule makers were dumb and should have reduced the maximum height of the chassis at the same time but they left this the same which is 75mm higher than the nose. Hence the ugly step-nose cars. McLaren have got a seamless beautiful car by not having a chassis at the maximum height and it looks like the Lotus is somewhere in between. I think that they will both suffer because of this .... Time will tell.

F1 » Lotus launches new E20


@Marc , Apparently the air flowing under the car is as important as the air flowing over the car. The diffuser or floor is designed to ensure the smoothest exit for the air flowing under the car. The quicker the air exits the more downforce the car generates. For this you need the front of the chassis to be as high as possible which is 625mm. For safety reasons the maximum height of the nose is 550mm. Hence the 75mm step. The gain that you have by the higher chassis is double what you lose by the inefficient aero over the step.
