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 waxes poetic about Le Mans

Audi did it again this year at Le Mans, but it wasn't arguably a harder job than it's been in the past few years. The Four Rings has put together a five-minute recap of the 24 hours in the wet and the dry at La Sarthe, showing a lot of the low points and the one high point that makes them all worth it.
Perhaps even better than the footage are the driver interviews. Audi has owned Le Mans for more than a decade, but none of the drivers take it for granted - team driver Marc Gene said, "I also think that Le Mans picks the winner... At some point, he just decides which car and which drivers are going to win that race."
You can check it out in the video below. And be sure to hang around for the tribute at the end.

VW to pay $1B in settlement with US government over V6 diesels

Volkswagen and the US government have come to a settlement for the civil claims against the automaker's 3.0-liter, diesel V6s. Over 83,000 V6 TDI-powered models are currently prowling US roads in violation of emissions laws. The settlement allows VW to recall over 75 percent of its cheating V6 diesels – about 63,000 units – and bring them into compliance. These represent newer VW Touaregs, Audi A6, A7, A8, Q5, and Q7s, and Porsche Cayennes built between 2013 and 2016. According to the company, the recall will bring these so-called Generation Two engines up to emissions specs, provided the EPA and CARB okay the modifications. Should the regulators say no to VW's tweaks, the company will buy back or terminate leases with the affected owners. For older V6 TDIs built between 2009 and 2012, Volkswagen will do broadly the same thing, only in reverse. It will lead with buy backs of older Touaregs and Q7s – the only vehicles the company sold with the earlier engines – but could offer fixes if EPA/CARB give the okay. As part of its agreement over the emissions-cheating V6s, Volkswagen will contribute $225 million to the "environmental remediation trust" it established as part of its settlement over cheating 2.0-liter TDIs. VW is also on the hook for $25 million with CARB, bringing the total for the six-cylinder part of its emissions cheating scandal to around $1 billion, Automotive News reports. This initial agreement still needs approval from US District Court Judge Charles Breyer. Related Video:
