Red Bull team unveiled their second Renault powered car – RB4 – in Jerez, Spain. Same as its predecessor RB3 it has been designed by Adrian Newey.
As it became a trend in F1, it features the bridge wing, similar to what the team used towards the end of the 2007 season. It seems that Red Bull truly gives you the extra wings 
The car is quite similar to the RB4. The main changes very likely took part under the chassis. Let’s hope the team has found some cure for their reliability issues.
To remember how the RB3 looked like, here is the 2007 Red Bull F1 Screensaver
Red Bull also yesterday confirmed Sebastien Buemi as their reserve driver.
Toro Rosso team will be starting the 2008 season with their old car.
