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.

Malaise Era All-Stars

A few weeks ago, we bid a fond happy 40th anniversary to the automotive dark ages of 1973-84 that have come to be known as "The Malaise Era" - the performance ice-age when 160 horsepower was a lot and a 0-60 time of under 10 seconds was remarkable. Like music in the 1980s, everything in automobiledom didn't suck, however. There were a few bright spots. Here are five of our favorites:

Audi teases 700-hp Quattro Sport E-Tron concept for Frankfurt

Audi's trump card for the 2013 Frankfurt Motor Show has just been unveiled, sort of. It's called the Quattro Sport E-Tron Concept. Set to debut in a few weeks, sketches have been uncovered that show a few of the car's details, albeit in rough form. The news of a big-name Audi concept at Frankfurt has been swirling since June, when we first reported on it.
From the sketches, we see a car that has the same basic shape as the Quattro Concept from the 2010 Paris Motor Show, only with subtle tweaks and evolutions to a few features. The news isn't so much about the looks, though. It's the reports coming from Auto Zeitung and Audi enthusiast site Fourtitude.
Horsepower on the concept is expected to be in the neighborhood of 700 ponies - about 50 more than we initially thought - and will be split between a gas engine and an electric motor. Yup, that "E-Tron" name isn't just there for show. While it's not clear what the exact split will be between gas and electric power, we do know the same twin-turbo 4.0-liter V8 found in the RS6 and RS7 will be sitting under the Quattro's hood, and that the bulk of the power will likely come from here. We may not have power figures on the hybrid system, but we do know this concept is capable of running for 21.7 miles on electric power alone.
