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 to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

Updated Audi R8 GT caught testing

When Audi introduced the refreshed 2014 R8, one of the first things we noticed was that the new R8 V10 Plus offers identical output to the outgoing R8 GT, suggesting that this limited-production model was either due to be cancelled or poised for a serious power increase. Fortunately, these spy shots have us suspecting that the latter is more likely.
Like the previous R8 GT, this new model will likely hit the gym, dropping some weight and packing more punch, but while that's all speculative, we do see that better handling is definitely in the cards. Aside from the aero-improving chin spoiler, fascia winglets and fixed rear wing, this R8 also has upgraded brakes with bigger calipers and what appear to be cross-drilled ceramic rotors. We hear output could be increased from the current 560 horsepower up closer to the 600-hp range, and laid to the pavement via Audi's Quattro all-wheel-drive system. It also very likely that Audi will keep production numbers for a 2014 R8 GT rather low, with the outgoing model limited to just 333 units globally.
