24 September 2011 - Red Bull RB7 - revised brake ducts
 
At the rear of cars, brake ducts have become more and more important as downforce-boosting aerodynamic devices. The Red Bull ducts feature several small planes on the inside of the brake drum to help enhance downforce.
24 September 2011 - McLaren MP4-26 - new exhaust layout
 
McLaren are using a new exhaust layout in Singapore. Longer than the previous version, it has been combined with a new diffuser featuring a small, Red Bull-inspired flap in its central section.
24 September 2011 - Red Bull RB7 - revised front wing
 
Red Bull evaluated three different front wings in Singapore on Friday. Pictured is the one tested by Vettel and then used by both drivers during qualifying and for the race. There is a step on the main plane (left-hand arrow). This is similar in style to the solution introduced (but not raced) by McLaren in Spa. There is also a new upper flap (right-hand arrow), inspired by the one McLaren used in Monza.
25 September 2011 - Ferrari 150° Italia - modified exhaust
In Singapore Ferrari have modified their exhaust layout. The final section (see blue highlighted area) is a little narrower than before and no longer features the small stepped section which helped to blow air both under and on the top of the side channel.
