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 Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.

Audi builds 3-millionth A3

About a month after Volkswagen celebrated building its 30-millionth example of the Golf, Audi has announced that it has produced three million versions of its small hatchback, the closely related Audi A3. Probably more surprising than the fact that the A3 has moved in such big numbers since its global debut in 1996 is the fact that it has done so with relatively little support in the US, seeing marginal sales in the States since 2005.
The three-millionth A3 was a Sportback TDI model, but the lineup has grown this year to include a new sedan and S3 model, and the hybrid A3 E-tron is on the way. With these new models - especially the sedan in the US - we expect the A3 to continue to be a popular entrant in the premium small segment. Scroll down for Audi's official press release.
