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.

Is Audi getting complacent and suffering from brain drain?

The argument is made in a Reuters article: Audi is falling behind other luxury brands, such as Mercedes-Benz and BMW, due to a lack of research-and-development spending and "brain drain," or the migration of top executives and R&D chiefs to other parts of the Volkswagen Group. Reuters notes that Audi's current R&D chief is the third in 16 months.
Audi, which contributed to 40 percent of VW Group's $11.6 billion in profit the first nine months of the year, is delivering cars at a record pace: 1.31 million were delivered from January to October 2013 versus BMW's 1.35 million. Yet Audi, Reuters reports, doesn't have a halo car akin to BMW's new electrified i3 and i8 or an answer to Mercedes' plug-in-hybrid S-Class, and the R&D spending at Audi is less than BMW and Mercedes by a fair margin. It's noted in the article, however, that Audi benefits from other R&D spending within VW Group.
Reuters mentions that BMW "trumpets its new 'i' series" and the new Mercedes CLA and GLA ranges are winning "rave reviews" as part of its argument that Audi's recent lack of technological innovation could hurt future sales. Those cars do pack tons of new technology, some of which are firsts for mainstream production cars. But last time we checked, the i3 could be causing BMW's stock to slide, the CLA isn't receiving the rave reviews that Reuters would have you believe and the GLA hasn't been reviewed yet.

The 2017 Audi A6 is the great luxury sedan we forgot about

The current Audi A6 is getting old. This generation was first sold as a 2012, got a mild facelift for 2016, and is likely to be replaced for 2018 or 2019. So 2017 may be its last year, but it's still my favorite mid-size Germano luxury thing. I just had to be reminded of its existence. BMW and Mercedes-Benz have been making big noises in this segment recently, with a new 5 Series on the way and the recently launched E-Class, and that apparently distracted me enough from the A6. There's also the fact the Audi is starting to look a bit anonymous on the road. It's still handsome, sure, but it doesn't stand out like the related A7. The 2016 refresh did just enough to keep it looking contemporary, though, and for 2017 all A6s come standard with the S Line appearance package. That helps. What struck me about the A6 was that it doesn't feel dated inside. Everything is laid out nicely, it's just comfortable, and you can see out of it. The one I drove had the beautiful layered walnut trim – it looks like pin-striped wood. (And no, it wasn't painted this bright blue, although you can get that on a special-order car if you pay $3,900 for Exclusive paint.) There are no huge screens inside, and the A6 won't get Audi's Virtual Cockpit until the next generation, but I didn't miss any of that. All of the excitement of Virtual Cockpit's beautiful reconfigurable screens, and I had forgotten that the display between the gauges it replaces had a perfectly pleasant Google Maps view already. It's the same basic functionality as Virtual Cockpit here, you just can't press a button to minimize the real-life gauges. And I'm fine having actual gauges. I was somewhat surprised, however, to see Apple CarPlay pop up when I plugged in my phone. (It's included for 2017 as part of the Audi smartphone interface, which comes with the Premium Plus trim and above.) Using CarPlay is a bit weird without a touchscreen, just like it is on other Audis and Mercedes products, but the nice thing about CarPlay is that you really don't need to interact with it much, since there isn't much to interact with. Oddly, the touchpad on the center console doesn't work to navigate from CarPlay tile to tile. I got over that pretty quickly and just turned the dial when necessary. There's also a feeling that nothing's missing when you drive it, that Audi couldn't really add much to improve the experience. The car is incredibly smooth and comfortable going down the road.
