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.

Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

2016 Technology of the Year Finalist: Audi Virtual Cockpit

The heart of most infotainment systems is a touchscreen in the center console. In many systems, some information can be sent to the gauge cluster in slightly redacted form – stripped-down navigation commands, basic audio info, that sort of thing. To get the full story, the driver has to take their eyes off the road and look to the middle of the dashboard. Audi's Virtual Cockpit, in essence, ditches the center screen and places all that information in the gauge cluster. The high-resolution TFT screen is just over a foot wide, and it has two main modes: Classic view, and Infotainment view. Classic looks like many other traditional TFT gauge clusters, with large traditional gauges and the ability to display a decent amount of information in the space in-between. Go into Infotainment view, and the gauges shrink and head to the lower corners, freeing up a much larger amount of real estate for, say, the nav system map. The gauges also get out of the way when utilizing the menu, entering a destination, or that sort of thing. The four main modes are standard stuff. Virtual Cockpit will show you navigation, media, phone, and trip computer information in large or small formats. You interact with Virtual Cockpit with a familiar MMI wheel-type controller in the center console, like in many other Audis, or with buttons and a scroll/push wheel on the left side of the steering wheel. Climate control functions are handed by physical controls cleverly integrated in the center three vents. It takes a lot of processing power to make all this work as well as it does, and that's handled by NVIDIA's Tegra 3 processor – a quad-core processor usually seen in tablets and smartphones. The system is quick and responsive, and we found the high-resolution screen to be impressively sharp. If there's a downside, it's that Virtual Cockpit doesn't leave an opportunity for a passenger to step in and, say, enter a destination or change the radio station without altering what's right in front of the driver. It could be inconvenient at best, distracting at worst, to have the nav system directions you're trying to follow suddenly be superseded by the audio menu. Adding a small secondary screen for the passenger could be one fix; a connected companion smartphone app another. In the meantime, it's an impressive implementation of a clever idea.
