McLaren MP4-29 Rear Suspension

This unusual solution has been garnering a lot of attention at the opening pre-season test at Jerez. 


McLaren have designed the MP4-29's rear suspension, in particular the toe link and the rear leg of the lower wishbone, so as to create elements which respect the 3.5:1 dimension ratio required by the regulations, but which are in effect large aero devices. 


At lower speeds they help improve the extraction of air from the rear diffuser, thus boosting downforce, while at higher speeds movement in the suspension components means they cut drag. 


The solution is considered legal by the FIA, but could lead to clarification requests from rival teams - especially as it's one that cannot be easily copied, since it would require a complete redesign of the rear suspension.
