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 A3 outselling Mercedes CLA 2 to 1 in its first 3 months on sale

The Audi A3 is on fire in US showrooms. Not literally of course, that would be horrible, and the situation we're referring to is a good thing indeed, as the Four Rings has a serious hit on its hands with the compact luxury sedan. Looking at just its first three months on the market, the entry-level model is outselling the Mercedes-Benz CLA-Class by nearly two to one.
The CLA was one of the hottest new cars of last year. Mercedes even called it the company's best launch in 20 years, but it sees as if that early sales performance has not been sustainable. According to Bloomberg, the CLA has seen its sales drop year-over-year in seven of the last eight months, and the new A3 came at just the right time to fill that void.
In June, Mercedes shifted 1,658 CLAs in the US, compared to 2,452 for the A3. The Merc has sold more units so far this year but only because the Audi sedan has only been on sale for three full months. With the two cars being relatively comparable as compact, front-wheel-drive, German luxury sedans, it appears buyers prefer the Four Rings over the Mercedes star, so far at least.

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.
