The monocoque, combustion engine and transmission as one unit ensure optimal rigidity. While the V4 engine fulfils a load-bearing function within the chassis, the hydraulically operated sequential 7-speed racing gearbox made of aluminium is mounted in a carbon structure. For 2016, the gearbox and gearbox mounting remain structurally identical. The focus for development on the gearbox was on weight reduction.
For even better driving dynamics, balance, traction, grip and set-up options, the Porsche 919 Hybrid received a new front axle and an optimised rear axle for 2016. After intense testing in February, an increase in performance on the part of the Michelin tyres is expected.
Porsche took a three-pronged approach to aerodynamic improvements for the first time in 2016. Until now, Porsche settled on a compromise for the season-opening round of the World Championship and campaigned the 919 with lower downforce than would have been ideal for the Silverstone circuit. This compromise was for the sake of the season highlight at Le Mans. The French racetrack with its long straights requires very low drag, which means downforce must be limited to what is absolutely necessary. In 2016 the 919 will start the season running a high downforce package. It will be tackling Le Mans with an extremely low downforce configuration and will have another high downforce package for the following six WEC races. The regulations prohibit more than three aerodynamic configurations per year.
The changes to the aerodynamics were driven by further improvements in efficiency and more stable handling in different driving situations. Influences such as side winds, changes in balance under cornering as well as yaw and roll angles were further reduced. << Prev Page 3 of 3
