Malaysia Grand Prix 2010 : Technical news (part 1)

Mercedes MGP-W01 - revised rear bodywork



Here you can see how Mercedes have evolved the bodywork around the MGP-W01's exhausts. In Melbourne (see inset) there was an additional gill linked to the exhaust opening (highlighted in blue), which respected the single-opening rule. In Sepang they have modified the bodywork (see main drawing) to create a wider opening around the exhaust to aid cooling. The team have also opened two small windows at the point where the bodywork meets the car's floor (highlighted in blue).

Toro Rosso STR05 - modified exhaust



To improve the cooling of the Toro Rosso in Malaysia's high temperatures, the team have modified the bodywork around the exhausts. Unlike the exhaust used in Melbourne (see inset), the exhaust opening is no longer visible from the side (see main drawing). This solution was also used in Bahrain.


Red Bull RB6 - front brake-rim attachment



In both the first two races Red Bull suffered problems with their front wheel upright's brake-rim attachment - on Friday morning in Bahrain on Vettel's car, and on his again in Melbourne when the front-left wheel came loose. For Malaysia the team have worked hard to avoid the problem, checking the assembly of the components (hub, wheel nut and rim) after nearly every run. As you can see in the drawing, Red Bull don't have the locking pins (arrow) in the hub plate but instead in the inside of the rim.
