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.

2015 Audi TT picks up the style, pace with Xcar

With the original TT, Audi arguably valued style over substance. The equation reversed - at least to an extent - with the second-generation model. But with this latest MkIII version, the German automaker appears to have finally imbued its compact sports car with the performance to back up its runway looks.
That is, at least, what the team at Xcar has to say, having driven the latest Audi sports coupe on the rainy roads of Scotland - taking in its crisp lines, sharp handling, nippy performance and impressive technology along the way. But don't let us spoil it for you: Watch for yourself to see how the new TT measures up against its stylish forebears.

Audi Q7 testing gives us clearer view of new look

Audi just announced its intentions to build the Q1 in 2016. By that time, the company will already have introduced the opposing bookend to that subcompact utility vehicle, the fullsize Q7. The last time we saw the next-gen Audi Q7 out testing, our spy shots were very low quality and didn't reveal much about the luxury SUV. This time around we're able to make out a few key elements about the Q7.
For starters, the unfinished headlights have a stylish, wave-like lighting element with a three-dimensional appearance, while the rear of the Q7 will definitely get a similar wraparound liftgate as the current model. Overall, this prototype looks to be about the same size as the existing Q7, so it will be interesting to see how Audi squeezes almost 800 pounds from the SUV's curb weight. The diet will surely help improve efficiency, and we also hear that Audi is considering a plug-in hybrid model in addition to the standard gas and diesel variants.
Riding on a shared platform with the next-gen Volkswagen Touareg, Porsche Cayenne and the upcoming Bentley Falcon SUV, the next Audi Q7 is expected to bow in late 2014 for the 2015 model year.
