Not strictly a change, but much more visible in Brazil thanks to David Coulthard's one-off white livery, was this interesting detail regarding Red Bull's placement of ballast in the front wing assembly. As on most cars, the RB4 has tiny blocks of wolfram/tungsten inside the wing's main profile,...
When BMW Sauber introduced this solution at the start of the season it looked very radical. It now seems less so, having inspired similar, if slightly differently shaped designs from Honda and McLaren. In Singapore, Red Bull have introduced an almost exact copy to help cope with the track's specific...
An interesting change to the RB4 in Valencia is the introduction of a curved upper link (inset) connecting the bridge wing to the top of the nosecone, as on the McLaren. This solution guarantees adequate stiffness in the bridge assembly, so that it doesn't obviously flex. It also helps to cut...
During the test session at Silverstone ahead of this weekend's race, Red Bull evaluated a variety of solutions to improve the RB4's balance. One outcome of this intensive work was a revised front wing, as shown in the lower drawing (previous version above). This sports a different main profile that...
At the last round in Montreal Red Bull modified the RB4's bridge wing to prevent it from flexing, to comply with the latest FIA rule clarifications. For Magny-Cours, the team have revised the central section of this element (see inset). By increasing the depth of the bridge wing (red arrow), the...
For Monaco Red Bull revised the bridge profile of the RB4's front wing. The central section was flattened and broadened, while the outer extremities were widened and now feature a long deep slit (see inset). These changes were adopted to increase the level of downforce at the car's front end. The...
A small but interesting change was introduced on the RB4 in Turkey, following on from the big aero overhaul debuted at the previous round in Spain, and it's one that will play an even more relevant role at the next race in Monaco. A deep V-shaped cut was placed in the middle-top of the rear wing...
During testing in Barcelona, Red Bull introduced a striking 'shark fin' extension to the RB4's engine cover (red arrow). The modification dramatically increased the surface area of this section and was introduced to provide better airflow to the rear wing and maximize the car's stability under...
