Driving quality and tyres

Alongside the mechanical enhancements made to the chassis, a number of software innovations have helped to further improve the driving quality of the 919, particularly in terms of traction control and hybrid management. Both of these factors have a significant impact on the service life of the tyres, and this consideration is set to take on even greater importance in 2017. LMP1 teams will now have three sets of tyres fewer available to them for each race weekend and car, so tyre sets will need to withstand double stints of racing on a more frequent basis – lasting the equivalent of two tanks of fuel, or a driving time of around one and a half hours. Andreas Seidl: “Working together with our partner Michelin, we have prepared intensively so that we are able to keep up the pace right through to the end of the race, even when we’re driving in double stints. All the races, whether six hours or 24 hours in duration, will be real sprints to the finish this year, too.” During the night at Le Mans, when temperatures are cooler, even quadruple stints on one set of tyres are possible.
WEC – the ideal platform for technological pioneers
With its unique efficiency regulations for Class 1 Le Mans prototypes (LMP1), the WEC represents an ideal platform for Porsche – and it was these regulations that fuelled the company’s return to elite motorsport in 2014. The regulations provide engineers with an unusual degree of freedom to introduce different drive concepts and require forward-looking technologies such as hybridisation, highly efficient engine downsizing and consistent use of lightweight construction. As a result, the WEC provides the perfect platform for Porsche to develop and test innovations for road-going sportscars.
