Mc Laren MP4/28 – winter testing (pre season) tech summary
Chassis : MP4/28
Engine : Mercedes-Benz FO 108F
The most striking differences between the new MP4/28 and its ancestor is the higher nose, redesigned radiators inlets ,and the pull rod front suspension ( the MP4/27 had push rod) . However special treatment on detail was taken all over the car . Worth’s mentioning that Mc Laren housed the driveshaft inside the lower wishbone of the rear suspension system to cut drag . This tactic is not new for Mc Laren because back in 1999 the MP4/14 had its steering wheel merged inside the upper wishbone of the front suspension .
Winter testing updates :
During winter testing the car showed remarkable speed but also was proved recalcitrant for mechanics to find the ideal set up . Since launch the car inherited three versions of nose vanes in total , horizontal, a slat on top of the sidepod and a new simpler front wing .
Aerodynamic performance : promising but very difficult to find the ideal set up
Speed :. Speed is there but not yet unleashed . Understeer is an unsolved yet problem probably because of the introduction of a pull rod front suspension
Tyres management : well but suffers degradation
Reliability : pretty good
