For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.

2016 Audi A4 is larger, lighter [w/video]

The 2016 Audi A4 arrives with a bang, but no surprises. We say that because the formula for creating the new A4 is one we know all too well. Make it larger, add a bunch of content, reduce weight, and improve both power and efficiency. It's a recipe for success, and this fifth-generation A4 looks to be a solid contender against its chief rivals, the BMW 3 Series and Mercedes-Benz C-Class. The shape hasn't changed; it's immediately recognizable as an A4. Instead, this new model updates that familiar design with sharper lines, similar to what we've seen on the new Q7, or even the R8. The big story here is that the 2016 A4 is up to 264 pounds lighter than its predecessor, depending on trim and engine. Additionally, the A4 is the most aerodynamic car in its class, boasting a drag coefficient of just 0.23. A fresh, modern cabin lies within that lighter shell – one that looks decidedly more upscale than the last A4. Many elements are reminiscent of the Audi Prologue concept that we first saw (and drove) in Los Angeles last year – specifically, the steering wheel, and the new MMI controls. In fact, Audi has positioned its infotainment controls closer to the center console – in front of the gear selector. This reminds us of the current A8, where Audi specifically designed its shifter to act as a sort of wrist rest. You can rest your arm on the gear lever and still access all of the MMI functionality. Speaking of which, that's the latest generation of Audi's MMI interface, packing navigation, touch capability, LTE connectivity, and WiFi in the 8.3-inch color display. Audi isn't saying which engines will come to the United States right now, but when the new A4 launches, it'll be offered with three gasoline and four diesel engines in Europe. Our best guess is that the US-spec car will come with the latest 2.0-liter TSFI turbocharged inline-four with 272 horsepower, as well as Audi's tried-and-true 2.0-liter TDI diesel four. Front- and all-wheel drive will be available, and for the first time, two-wheel-drive models will get a proper dual-clutch transmission – no more CVT. There's a whole lot more to lean about the A4 in the press release, posted after the reveal video. You can also see the 2016 A4 in sedan and Avant forms in the galleries above and below – it's unclear if the wagon will make its way to the US. The A4 Avant has been sold here before, but currently, Audi only offers that more functional bodystyle in Allroad spec.

Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:
