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 SQ7 TDI would make a compelling option in the US

Intrigued by the prospect of the new Audi SQ7 TDI? We are. And promising though the signs may look, we'll likely still have to wait a while before Audi confirms whether it will bring the new performance diesel crossover to North America, much less announce pricing. But based on the sticker just attached in Europe, the SQ7 looks like a compelling choice – if a difficult one to compartmentalize. Audi has priced its new top-of-the-line crossover at 89,000 euros. Adjust for taxes and exchange rates, we'd likely be looking at an MSRP of roughly $86,000 in US showrooms, if and when it gets the green light from Ingolstadt to embark on the the transatlantic voyage. That places the SQ7 above any diesel crossovers we get in the US, but significantly undercuts the large, gasoline-powered performance SUVs we do get – like the BMW X5 M ($99k), the Mercedes-AMG GLS63 ($124k), and the Porsche Cayenne GTS ($95k) or Cayenne Turbo ($115k). The diesel performance version of the Q7 has more direct competition overseas in the forms of the Porsche Cayenne S Diesel and BMW X5 M50d – but the Audi offers a bigger bang for only a little more buck (or euro) than either. Where Porsche offers 385 horsepower and 627 pound-feet of torque for ˆ87.4k, and the BMW boasts 381 hp and 545 lb-ft for ˆ85.7k, the Audi trumps both with a prodigious 435 hp and a massive 664 lb-ft for only a little more cash. The SQ7 also outperforms both by a significant margin, reaching 62 miles per hour from a standstill in a scant 4.8 seconds, versus the 5.3 achieved by both the Cayenne S Diesel and X5 M50d. That places Audi's latest in something of a category of its own, leaving its similarly priced but less potent diesel competition in its wake. And with more torque but less power, it rapidly encroaches on the levels of performance offered by the top gasoline-powered performance crossovers – whose 0-62 sprints range from 4.2 seconds (in the X5 M) to 4.6 (in the GLS 63). The question on our minds is whether Audi will bring the new SQ7 TDI to these United States. Our sources tell us the chances are good, but far from confirmed. Our hopes were further raised by its appearance in the latest Captain America movie. But it's the SQ7's performance vis-a-vis the competition – difficult as it may be to categorize – that has whetted our appetites the most.

VW Group recalls 27k Touaregs, Audis and Porsches for fuel leak

The Volkswagen Group is one of the most expansive in the entire industry, and shares parts across more product lines than we could wrap our heads around. So when the German megalith finds a fault in one of its components, it has the capacity to spread like wildfire. The latest set of recall notices from the National Highway Traffic Safety Administration covers vehicles from the Volkswagen, Audi and Porsche divisions. The problem revolves around the fuel injection system, which could potentially leak and cause a fire. The recall affects – deep breath now – the 2012 VW Touareg Hybrid, the 2011-12 Porsche Cayenne S Hybrid and Panamera S Hybrid, 2011-12 Audi S4, S5 and Q7 and the 2012-13 Audi A7. All told, that amounts to 27,376 units, the owners of which can expect to hear from the manufacturer to have the fuel rails replaced, along with their corresponding seals (having nothing to do with marine mammals writing letters). RECALL Subject : Fuel Injection System Fuel Leak Report Receipt Date: JAN 20, 2015 NHTSA Campaign Number: 15V019000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 26,008 Manufacturer: Volkswagen Group of America, Inc.
