Audi reveals even more efficient 2015 R18 E-Tron Quattro

We've seen two of this year's LMP1 manufacturer challengers – Porsche's updated 919 Hybrid and Nissan's GT-R LM Nismo. Audi has finished cooking up the successor to its Le Mans champion and unveiled the fifth-generation R18 E-Tron Quattro, even better than before. The bodywork monocoque is carried over, but the body around it has been reshaped to improve airflow from front to rear with a new hood, front fenders and wheel arches, and radiator configuration. The engine cover behind the cockpit is shrunk more closely around the engine, and there are new headlights. The hybrid system can expend double the energy per lap this year, putting Audi in the four-megajoule class under the energy-use regulations. That extra energy will come from 17-percent more capacity built into the flywheel storage system and an electric motor good for 272 horsepower. The revisions haven't increased the weight of the car, pegged to the minimum allowed at 870 kilograms. They have, however, forced changes to the TDI engine, which has to use 2.5-percent less fuel per lap to offset the increased hybrid output. The 558-hp V6 has been optimized such that it "managed to more than compensate for the loss" of fuel allowed, and Audi expects "significantly" lower lap times this year and less fuel used. We're still waiting to see what Toyota has done to its World Endurance Championship-winning racer, but we're already looking forward to this year's Le Mans. It's going to be cracking. You'll find a press release below the videos with more info on the Audi.

In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season's pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class. A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. "The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used.

Audi promises next A8 on sale by year's end, LED Matrix lamps to be available [w/video]

Audi has just released details about its new Matrix LED headlamps, but just as illuminating as the new lighting technology is confirmation that the next A8 will appear "on the market at the end of 2013." While Audi is calling the model new, expectations - and the spy shots above - suggest more of a traditional mid-cycle refresh.
Audi says that its new A8 Matrix lights are comprised of 25 high-beam LEDs, clustered in groups of five paired with reflectors. Unlike traditional automatic high-beam setups, the Matrix array is so precise that it "blanks out light that would shine directly onto oncoming and preceding vehicles" while continuing to use full high-beam power on other sections of the road and shoulder not occupied by other vehicles. Further, the camera- and electronic brain-governed system can dim or extinguish LEDs as necessary to deal with traffic. The active system also differs from today's adaptive headlamps by not requiring servo motors to direct light, yet they can still function as cornering headlamps - ones that can predict a road's trajectory because they are linked with the car's GPS system. Interestingly, the system also works with Audi's optional night vision system. When the latter detects a pedestrian in the dark, it automatically flashes a batch of LEDs to put both the driver and pedestrian on notice about each others' presence.
Only one problem in all of this trick lighting business: they aren't legal here in the US, at least not yet. Audi and other automakers are currently petitioning the National Highway Traffic Safety Administration, trying to sell the government agency on the technology's safety benefits. For the moment, Matrix headlamps are likely to remain forbidden fruit, but you can check them out and see what you might be missing in the video below. As for the 2015 A8, we're guessing it'll surface at the Frankfurt Motor Show in September.

Bentley doubles down on diesels with a triple-charged Bentayga

Volkswagen Group isn't totally giving up on diesels. While its flagship VW brand is clearly tarnished, the ultra-luxury Bentley division just revealed plans for its first oil-burner, a triple-charged 4.0-liter V8 that produces 429 horsepower and 664 pound-feet of torque. If the powertrain sounds familiar, that's because it's the same one found in the Audi SQ7 TDI. It's a clever system capable of giving what Bentley claims as the world's fastest diesel SUV a top speed of 168 miles per hour and a zero-to-62 mph time of 4.8 seconds. The SQ7 TDI can get to 62 mph in the same time, but is electronically limited to 155 mph, because it wouldn't make sense if the cheaper SUV could outperform the much more expensive one. The Bentayga also emits the lowest CO2 output of any Bentley and has a range of over 621 miles on one tank. Despite having a curb weight of 5,269 pounds, Bentley claims the Bentayga can get a combined rating of 35.8 mpg on the European cycle. The Bentayga Diesel may not be as powerful or as fast as the W12-powered model, but it's a lot more fuel efficient as the latter achieves a combined rating of 21.6 mpg on the European cycle. Other than the new engine, the Bentayga diesel is nearly identical to its gasoline-powered twin except for some discreet "V8 Diesel" badges on the front doors, a new exhaust outlet design, and a black grille. A Bentley spokesperson confirmed that the Bentayga diesel would not be sold in the US. And since Bentley won't be at this year's Paris Motor Show, don't get your hopes up on spotting the vehicle there. The diesel-powered SUV will go on sale in Europe early next year, which will be followed by its release in Russia, South Africa, Australia, New Zealand, and Taiwan. Pricing for the SUV has not been announced yet.
