Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Audi takes cars that park themselves to a whole new level

Autonomous cars are impressive displays of in-car technology, but what exactly would the benefit of such systems be for the average driver? Audi has answered that question by showing off its Piloted Parking system for the Audi Connect at CES 2013.
Installed on this Audi A7, Piloted Parking allows a driver to drop themselves off and have the car autonomously drive away on its own and find its own parking spot. The car can then later be retrieved by "calling" it back with a specially designed smartphone app. We'd be lying if we said this didn't bring back memories of Michael Knight summoning KITT with his wristwatch. The most impressive part of this car might be the fact that the car is fully autonomous but doesn't have any obvious sensors or monitors on the exterior of the car like many other self-driving cars have.
