New details have emerged on Audi's upcoming diesel supercar, internally known as Scorpion.¬†
Set to be called R10 in production form, the car will borrow much of its technology from Audi's Le Mans-winning R18 e-tron race car, including its drivetrain.
According to Car and Driver, the R10 will use a version of the 3.7L V6 turbodiesel found under the hood of the R18 e-tron, along with the race car's front-mounted hybrid system.¬† Total output remains unknown, but both horsepower and toque could top the 700 mark.
Audi was considering Volkswagen's corporate 3.0 TDI -- which is used in vehicles like the Porsche Cayenne and VW Touareg -- for the R10, but decided that engine was too run-of-the-mill for a high-end sports car.
"It wouldn’t make sense to use anything but the R18′s racing engine in the Scorpion,” an inside source told Car and Driver.
Audi might develop a carbon fiber chassis specifically for the R10 in order to keep the weight as low as possible. ¬†If that route is written off as too expensive, the car might ride on the upcoming MSB platform that will underpin the next-gen R8, among other high-end Volkswagen products.
Platform aside, the R8 and the R10 will be completely different inside and out. ¬†The R10 will be what Audi quattro boss Franciscus Van Meel bills as "the absolute best¬†supercar" available, a no-compromise track-bred machine that will be able to take on the McLaren P1.¬†
The R10 is still at the embryonic stage and it has yet to be given the green light for production. ¬†Key members of Audi's top brass see potential in adding a halo car to the lineup, however.
"There is definitely room for a super sports car above the R8," said Wolfgang Durheimer, Audi's head of technical development, in an interview with Auto Express. ¬†"If we made this a diesel hybrid it could be a hot seller. ¬†What always sells is performance - if its quick, has low consumption and looks cool, I'm sure it would be a success."
If Audi moves ahead with the R10 its debut is at least five years away. ¬†
