Porsche to run Le Mans aero parts in Spa World Endurance round

The aerodynamic set-up in which the two 919 Hybrids will race in the Spa 6 Hours on Saturday was described as "a mixture between the Silverstone [high downforce] and the Le Mans specifications [minimum drag]" in a statement from Porsche.

Team principal Andreas Seidl said: "A car's configuration for what is a seven kilometre-long, up-and-down-hill circuit is always a compromise between enough downforce for the fast corners and little drag on the long straights.

"At our endurance test at Aragon last week we were examining our Le Mans aero package for the first time and will now use components of that in Spa."

No photographs of the car in Le Mans trim have been released by Porsche.

Porsche also competed in low-downforce trim at Spa last year, when it narrowly lost out on victory to Audi.

It ran aerodynamics known internally as 'kit 2', similar to what had been raced at Silverstone, before its definitive low-downforce spec came on stream for Le Mans.

It opted to focus early aero development on Le Mans and did not bring out its high-downforce kit until the Nurburgring WEC round at the end of August.

Toyota will run its TS050 HYBRIDs in high-downforce configuration at Spa.

Audi has yet to reveal the aerodynamic configuration in which its latest R18 e-tron quattros will race.

Porsche completed more than 7600km over four days of endurance testing at the Aragon circuit.

It has a further Le Mans simulation scheduled at the Spanish track after the Spa WEC round.
