TechDrive Garage| Test Drive The 2014 Audi R18 E-Tron
Audi just completed the design of its R18 e-tron quattro race car around the 2014 season’s new regulations, and it features more advanced technologies. Valued at $30 million and packing a diesel-hybrid powertrain, the all-new R18 is the ultimate embodiment of Audi’s racing experience and know-how.
And there are some things about the R18 you need to know, according to Audi Sport Head Dr. Wolfgang Ulrich:
#1: The laser headlights were designed based on satellite’s instructions
Audi’s racers experienced that adaptive headlights affect their actual capability, especially when linked directly to the steering angle. That’s why the R18’s new laser high-beams’ swiveling action is GPS-linked and programmed for each track, giving the racers the best support for each next turn.
#2: The laser headlights aren’t always on
In order to avoid blinding everyone in the pit lane, these headlights will be automatically shut off at lower speeds (below 55 MPH).
#3: The tires are narrower than before
Since the 2014 World Endurance Championship rules has changed, the R18’s tires are actually narrower than previous years. This change gives the car a more agile feeling, but also reduces the sensation of stability.
#4: It’s very efficient!
The R18 uses diesel-hybrid engines, which converts thermal energy from the exhaust gas flow into electricity that’s directed to the flywheel storage. The flywheel’s reserve can be sent to either the front axle motor or to the electric turbocharger to enhance acceleration.
#5: The fuel-injection pressure really high
That figure is an astounding 34,800 psi thanks to a cleaner burn-and-boost power system.
#6: It’s louder than before
The noticeably increased volume is attributed to the rerouted exhaust, which now exits out of the car’s rear instead of under the floor.
