– The six-hour race on the Fuji International Speedway is the seventh out of nine rounds of the 2016 FIA WEC and starts on October 16 at 11:00 hrs local time (04:00 hrs in Central Europe).
– The WEC efficiency regulations limit the amount of energy that can be used per lap. In Fuji the Porsche 919 Hybrid can use 4.15 megajoule of electrical power from energy recovery systems and 1.169 kg or 1.559 litres of petrol.
– At normal race speed (no safety car) the Porsche 919 Hybrid is due for refuelling after every 38 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 may use only one wheel gun. 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.
– 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 on the Fuji International Speedway is 4.549 kilometres and has 16 corners – 10 right-handers and six left-handers.
– In 2005 the circuit was rebuilt for safety reasons and became, once again, the venue for the Japanese Formula One Grand Prix in 2007 and 2008.
– From 1982 to 1988 the Sports Car World Championship had a round in Fuji. In 1983 Stefan Bellof set the fastest ever recorded lap at the wheel of a Porsche 956 in 1:10.02 minutes. This was, however, on the old track layout when a lap was only 4.360 kilometres.
– In 2015 the WEC race was started behind the safety car because of heavy rain. In 2014 the track was dry on race day. But the weather in the Japanese Alps can be very changeable at this time of the year. In 2013 heavy rain made it impossible to run the WEC race. Not forgotten is the downpour back in 1976 which caused Niki Lauda to pull out of the race and gave the Formula One World Championship title to James Hunt.
– Mount Fuji is an active volcano that last erupted in 1707. It is the highest mountain in Japan at 3,776 metres and is regarded as a holy mountain.
– The circuit is located about 100 kilometres southwest of the capital of Tokyo on the Japanese main island of Honshu.
