Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain

If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly. Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles – it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management – the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency. Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles. The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van. The Audi A7 Sportback h-tron quattro It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars. "The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e-quattro, its two electric motors drive all four wheels," explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "The h-tron concept car shows that we have mastered fuel cell technology.

Audi's next-gen "matrix beam lighting system" under threat from Washington

Automotive News reports Audi may have a hard road ahead of it when it comes to convincing federal regulators to allow the company's new matrix beam lighting. The system uses small cameras to detect other vehicles on the road and darkens specific elements of the high-beam pattern to provide maximum nighttime visibility without blinding other drivers. Audi has been displaying this technology on its concept cars for a couple of years now (including the Crosslane Coupe Concept shown above at its 2012 Paris Motor Show reveal). Audi hopes the technology will effectively do away with the industry's current high and low beam settings, but the National Highway Traffic Safety Administration doesn't allow such a system under its current laws. Federal Motor Vehicle Safety Standard 108 specifically says headlamps are not to shine in this dynamic of a way.
Audi has asked has asked NHTSA for more clarification to determine what, if any elements of the matrix beam lighting technology can legally be used on US-specification vehicles. But American buyers may have to settle for systems that automatically dim their high beams until the rules get a bit more clarification.

Audi reveals Prologue Allroad concept ahead of Shanghai

Audi kicked off the Prologue series of design studies with the coupe concept unveiled in LA, then followed up with the Prologue Avant wagon at the Geneva show. Now, we're seeing the third iteration in the form of the Prologue Allroad concept. Set to be unveiled next week at the 2015 Shanghai Motor Show, the Prologue Allroad picks up where the previous two left off, but takes it in a more rugged direction. At 16.8 feet, it's longer than both of the previous concepts, and stretches out to the same length as a standard-wheelbase A8. It also rides three inches higher than the Prologue Avant concept. Not only is it larger than the preceding showcars, it's also more powerful. Under the hood sits a hybrid powertrain that pairs a 4.0-liter twin-turbo V8 to an electric motor integrated into eight-speed automatic transmission. Together they produce a whopping 738 horsepower and 664 pound-feet of torque, driven to all four wheels to send the concept to 62 miles per hour in a scant 3.5 seconds – all the while returning a claimed equivalent of 98 miles per gallon. If that's not the best of both worlds, we don't know what is. Plus, the car packs an inductive charging system that Audi says it's developing for production. Massive 20-inch brake discs keep that performance in check, sitting inside 22-inch wheels, all mounted to an adaptive air suspension and four-wheel adaptive steering. Other exterior features include door lock sensors integrated into the window frame, Matrix laser headlights and LED taillights. Inside it's all angular yet elegant, swathed in dark blue, beige and brown. Display screens abound, stretching across the dashboard with a deployable OLED infotainment display in the center console. There's another OLED screen for the passengers in the pair of rear seats, who can also dock OLED tablets in the front seatbacks. A pop-up "sound spoiler" promises to envelop the cabin in music, and there's inductive charging for mobile devices as well. Together with its conceptual stablemates, the Prologue Allroad concept points towards a stylish and technologically advanced future for Ingolstadt, and we're looking forward to seeing this show car transition into production as the next A6 Allroad. In the meantime, you can scope out all the details in the press release below and view the concept from every angle, inside and out, in the slideshow above.
