Audi reveals R8 E-Tron Piloted Driving concept at CES Asia

Designed as they are to take the driver out of the equation, you might think that the idea of an autonomous vehicle would seem diametrically opposed to that of a supercar. But Audi disagrees. The German automaker has cooked up a series of "piloted driving" concepts that are increasingly focused on performance, and this could be the ultimate iteration yet. Audi's latest Piloted Driving demonstrator is based on the R8 E-Tron. It's altogether almost identical to the one we saw in Geneva, packing an electric powertrain to deliver 456 horsepower, 679 pound-feet of torque and a 0-62 time of 3.9 seconds. Only in this case, it can do it all on its own, without any driver intervention. To pull that off, Ingolstadt has fitted this show car with an array of sensors, including a new laser scanner, multiple video cameras, ultrasonic sensors and radar transmitters at both ends – all handled by a central "driver assistance control unit." It's the latest in a series of concept cars that has already included a version of the RS7 Sportback designed to lap the racetrack, and the Prologue concept that drove itself to CES. This concept was similarly unveiled at CES Asia, the Eastern counterpart to the tech expo we usually catch in Las Vegas. Just what the point is in engineering (or buying) one of the best-driving cars on the market and then handing over its operation to a computer, we don't quite get. But at least we can rest easy knowing that Audi is not giving up on performance as autonomous tech turns the driver into just another passenger.

The technology study is one of the highlights of CES Asia, and it brings together future technologies – which relate to lightweight design, high-performance drive systems and functions for piloted driving. The Audi R8 e-tron piloted driving concept car is based on the multimaterial Space Frame of the new production R8. A rear car body module made of carbon fiber reinforced polymer (CFRP) integrates the luggage compartment, which extends the frame structure. The walls of the luggage compartment shell are corrugated, so that they can absorb extreme amounts of energy with little material weight in case of a rear-end collision.

2015 24 Hours of Le Mans live race report

Check back regularly for more race updates every few hours. No, you don't need to stay up for the entire 24 Hours of Le Mans, but if you want to catch any of the action, Autoblog friend Reilly Brennan has a handy guide. And to keep you up to speed on the latest race events, we'll be posting live from Le Mans with regular race reports.Hour 1: Five laps in, Audi breaks up the three Porsches at the front, with the #19 919 Hybrid, driven by Nico Hulkenburg, passed by all three R18s. Hulkenburg eventually took back fifth position only to fall back again after the first pit stop. Meanwhile, clutch trouble kept the #23 Nissan GTR-LM in the pits until 15 minutes into the race. The other two Nissans were forced to start at the back of the grid after failing to the meet the 110 percent qualifying speed regulation. At the end of the first hour, just 7.5 seconds separated the first six cars. Then the factory team #92 Porsche GTE car caught fire, with the the #13 Rebellion P1 car taking frontal damage in the ensuing carnage. With the safety car out, the field is once again bunched up.Hour 2: The slugfest between Audi and Porsche continues, with neither side backing off. Halfway through the second hour the #7 R18 passes both leading Porsches for the top position. After another round of pits stops Porsche regains the lead until lap 30, when the Audi overtake once again and quickly pulls out a three-second gap. Nico Hulkenburg passes the other two Audis to join his Porsche teammates. At the beginning of the third hour it's Audi #7, Porsche #17, #18, and #19, followed by Audi #8 and #9. 33 seconds separates this group, with Toyota a minute back from the front car.Hour 3: On track the action refuses to stop. Although it's early, Audi is looking strong with the overall lead in the #7. What's more is that the Audis run four stints per set of tires, while the Porsche cars have to change rubber every third stop. But after a quick refueling, the lead R18 gets a tire puncture and comes back in 3 laps later, allowing Porsche to take over the top two spots. Then as the hour closes out a yellow flag causes traffic to bunch up and the #8 Audi gets stuck with nowhere to slow down. Driver Loic Duval dives for the side of the road but hits the guard rail and careens across the track, damaging the front and rear bodywork. The rest of the car is still intact, though, and once in the pits Audi replaces the entire front and rear of that in only three minutes.

Audi's Q8 Sport concept packs an electric supercharger

Audi's Q8 Sport concept doesn't wear S or RS badges, but it does have impressive performance that would qualify it for one of those monikers. Beneath the tangerine skin, Audi says there is a hybrid V6 displacing 3.0 liters, which isn't particularly interesting, but the forced induction system is. Rather than a conventional turbo or belt-driven supercharger, the V6 uses an electrically-powered supercharger. Audi doesn't provide any details on what kind of compressor it is, but it says the total output of the engine and motor combo is 476 horsepower and 516 lb-ft of torque. This is apparently good for a 4.7-second sprint to 62 mph. This also isn't the first time Audi has implemented an electric supercharger, having used it before on the SQ7 TDI. That orange shell also has updates to show that this Q8 Sport is the fast one. Most of the brushed aluminum trim of the normal Q8 concept has been swapped for gloss black versions. The regular Q8's grille with its chrome vertical bars is also gone in favor of a black honeycomb piece. The fenders have all been stretched by half an inch, and the exhaust tips are now large ovals that protrude from the rear bumper. Audi still hasn't said anything about when a production Q8 will reach the market. However, there's clearly one coming soon, as we've spotted prototypes running around that look similar to the concepts. Related Video:
