2015 Audi A8 rises to meet the challenge [w/video]

It's turnover time in the extra large premium sedan segment. With Mercedes having stuffed HAL 9000 in its new S-Class, other luxury marques are quickly updating their own super sleds to keep up with this persistent march of technology. While far from a full redesign, the Audi A8 has changed enough for 2015 in terms of styling, powertrains and new technology to keep it in the conversation.
For starters, the A8's exterior design has been redone, with the most noticeable changes happening up front. The trademark 'gaping maw' grille is a little less gaping, while the headlights now feature a straight lower edge of LEDs, excising the old model's droopy-eyed look. Speaking of headlights, Audi now offers optional Matrix LEDs, the latest in headlight tech, with 25 individual elements per side that can be turned on or off and dimmed as the situation demands. The rear of the A8 has also been resculpted and looks very much inspired by the derrière of the A7, with a single chrome strip connecting the new LED taillights.
The A8's full suite of powertrains has also been upgraded, with the supercharged 3.0-liter V6 now producing 310 horsepower (up 20 according to Audi, though down 23 compared to the US-spec 2013 model). The twin-turbo 4.0-liter V8 is now rated at 435 hp, a solid 20-horse increase that lowers the car's 0-62 time to just 4.5 seconds. That's within spitting distance of the 520-hp S8's time of 4.1 seconds. That aforementioned super sport sedan's engine remains unchanged, as does the 6.3-liter 12-cylinder powerplant in the A8 L W12, but Audi's two diesel engines have both improved, with the 3.0-liter V6 producing an extra eight horsepower (256 total) and the 4.2-liter V8 gaining an extra 34 hp (385 hp) to go along with its more-than-adequate, though unchanged, 626.93 foot-pounds of torque.

Audi outlasts rivals to win 13th Le Mans title

As is so often the case, the 2014 Le Mans was a war of attrition, and Audi managed to prevail once again after all 24 hours had been recorded in the history books, with its Audi R18 E-Tron Quattro claiming first and second places, followed by Toyota in third. Drivers Marcel Fassler, Andre Lotterer and Benoit Treluyer inherited the lead in their No. 2 Audi after the No. 7 Toyota, driven by pole-sitter Kazuki Nakajima, was forced to retire with electrical problems in the 15th hour.
The No. 2 Audi led the race until it was forced to the pits to replace a turbocharger in the 17th hour, allowing the No. 1 Audi, driven by Lucas di Grassi, Marc Gene (who was a last-minute replacement for Loic Duval, who crashed hard during practice) and defending champion Tom Kristensen, led the race until the 21st hour, when it too had to pit with turbocharger issues. This gave the No. 20 Porsche of Timo Bernhard, Brendon Hartley, and Mark Webber the lead until it was forced off the track with gearbox problems, eventually finishing in 38th position.
In LMP2, the Jota Sport Zytek Z11SN-Nissan driven by Simon Dolan, Harry Tincknell and Oliver Turvey claimed victory, the first five LMP2 finishers all powered by Nissan. Down a level in GTE-Pro, No. 51 AF Corse Ferrari 458 Italia GT2 driven by Gianmaria Bruni, Toni Vilander and Giancarlo Fisichella finished one lap ahead of the leading Corvette Racing C7.R. And finally, the No. 95 Aston Martin Racing Vantage GTE driven by Kristian Poulsen, David HeinemeierHansson and Nicki Thiim won the GTE-Am race two laps ahead of a Proton Porsche 911 GT3 RSR.

Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.
