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's next R8 snapped running the 'Ring nearly naked

Following the debut of the Lamborghini Huracán, work is now well well under way on its cousin. That, of course, would be the next-generation Audi R8, the followup to the model that put Ingolstadt on the supercar map in 2006 and has been on the market ever since. That's an eight-year lifespan, though to be fair, for 2014 it has gotten a pretty meaningful update. Still, that's a long lifecycle, even if the Gallardo with which it shares its underpinnings was around even longer. In other words, it's about due for replacement.
Fortunately, that's just what Audi has in the cards. We've seen prototypes wearing heavy camouflage lapping the Nürburgring a couple of times over the past few weeks, but now it's been snapped nearly completely undisguised, with largely bare black bodywork giving us an even better look at what to anticipate.
So what are we looking at here? A sharper-looking take on the existing design, for starters, so onlookers and customers alike shouldn't have any trouble identifying this as an R8 - but a newer one at that. It seems to take some cues from the new TT, particularly around the headlights, with more squared-off elements throughout. There's an adaptive rear wing poking out the back and more pronounced side-blade intakes between the doors and the rear wheels, which themselves are wearing ultra low-profile rubber.

Audi recalls 2013-2014 S6 and S7 models over fuel line leak

If you've been driving a late model Audi S6 or S7, first of all, good for you. Secondly, you should be expecting a call from your local dealer as the Volkswagen Group and the National Highway Traffic Safety Administration have issued a recall.
The problem apparently involves a potential leak in the fuel line, which, as any mechanic or McGuyver fan could tell you, is not such a good thing. As NHTSA points out, it "may result in a fire."
The recall involves 3,594 vehicles in these United States, specifically model-year 2013 and 2014 Audi S6 and S7 models equipped with the 4.0-liter twin-turbo V8. (It does not, however, seem to affect the S8 or any of the Bentleys that are powered by the same engine.) Owners of said cars can expect to be contacted regarding how the problem will be fixed. In the meantime you can read the official notice below.
