Porsche 919 Hybrid, Porsche Team: Brendon Hartley, Mark Webber, Timo Bernhard

FIA WEC LMP1 Round 8 Shanghai

– The six-hour race on the Shanghai International Circuit is the eighth and penultimate round of the 2016 FIA WEC and starts on November 6 at 11:00 hrs local time (04:00 hrs in Central Europe).

– The official WEC App can be downloaded free of charge in its basic version and can be extended (not free of charge) by a live stream. Several live features, such as on-board cameras, timing and GPS tracking, are implemented in the Porsche Motorsport App (free of charge) and at porsche.com/fiawec.

– In 2015 Hartley/Webber (1:42.719 minutes) and Dumas/Lieb (1:43.488 minutes) locked out the front row of the grid. (In the WEC the average of the respective best laps of two drivers counts for the grid position.)

– Last year about two thirds of the race were held on a wet track. Bernhard/Hartley/Webber won ahead of Dumas/Jani/Lieb. What back then was the fourth one-two race result of the season for Porsche secured an early title win in the manufacturers’ world championship.

– The WEC efficiency regulations limit the amount of energy that can be used per lap. In Shanghai the Porsche 919 Hybrid can use 4.95 megajoule of electrical power from energy recovery systems and 1.395 kg/1.910 litres of petrol.

– At normal race speed (no safety car) the Porsche 919 Hybrid is due for refuelling after every 31 laps at the latest. 

– Refuelling and changing tyres may only be done sequentially, not at the same time. Only four mechanics may work simultaneously when changing tyres and also may use only one wheel gun at a time. That takes a lot longer than in F1, for example. 

– The drivers are normally only changed when new tyres are needed. 

– A set of Michelin slick tyres should ideally last two fuel tank fills. However, in order to set the best lap times, it may be sensible to change tyres more often.

– These different types of tyres can be used: three different compounds of slick tyres for dry conditions, a hybrid tyre (no profile either but softer cover) for mixed conditions and wet weather tyres. 6.5 sets of dry weather tyres are available per car for qualifying and the race. 

– A lap of the Shanghai International Circuit, used for Formula One Grands Prix since 2004, is 5.451 kilometres. It has 16 corners – nine right-handers and seven left-handers – of which the well known “snail corner” at the beginning of each lap counts as a double right-hander. From a bird’s eye view the track’s layout is reminiscent of the Chinese characters of “shàng” that translates into “upward” or “up” and also is part of the city name of Shanghai.

– The circuit is located about 40 kilometres outside the city centre.
