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.

VW internal investigation finds 'no evidence' against suspended engineers

Volkswagen is still working out the chain of events that led to emissions-evading software being installed in 11 million diesel vehicles worldwide and deciding who was responsible for the treachery. So far, the German automotive giant's internal investigation hasn't publicly named many suspects, and three suspended executive-level engineers have been found not to be culpable in the wrongdoing, according to an anonymous insider speaking to Reuters. VW knows that the software began being installed in the EA 189 engine in 2008. The internal investigation has found that the emissions-evading tech was created because the powerplant was found to fail US standards. Plus, the diesel mill wasn't meeting cost targets, according to Reuters. The automaker responded by suspending over 10 employees, but three top engineers among them might not have been involved. Those put on leave include Heinz-Jakob Neusser from VW, Ulrich Hackenberg from Audi, and Wolfgang Hatz who led Porsche's research and group-wide engine development. The internal detective work hasn't turned up any evidence against these three men. In addition to VW's own inquires, government investigators in both the US and Germany are taking a serious look into the company's actions, too. So far, the automaker is setting aside about $7.3 billion to pay to fix the vehicles with the evasive software. Depending on what authorities find, the costs could grow quickly. Beyond the financial implications, the scandal has led to a serious shakeup in VW's corporate structure. Related Video:

2014 Audi SQ5 ditches diesel, still packs a punch

Over in Europe-land, the Audi SQ5 is a diesel-powered monster capable of sending a whopping 479 pound-feet of torque to its wheels. Naturally, this beast isn't coming to the States, but that doesn't mean we're missing out on the whole SQ5 experience altogether. At the Detroit Auto Show this week, Audi is debuting a new gasoline-powered version of the hot crossover, and while it's not quite the oil-burning dreamboat we've lusted after from afar, we certainly wouldn't kick it out of bed.
Instead of a diesel, we get a boosted version of Audi's supercharged 3.0-liter V6, good for 354 horsepower and 346 pound-feet of torque. Running through an eight-speed automatic transmission, the SQ5 will reportedly be able to fire off 0-60 times in the low-five-second range and will top out at an electronically limited 155 miles per hour. Suspension upgrades are on hand to improve road-going prowess, but also lower the Q5's stance a bit, too.
Because this is an S model, there are plenty of visual upgrades on hand, including a more aggressive front fascia, 20-inch wheels and some pretty new colors including Estoril Blue and Panther Black. Interior upgrades like Alcantara trim and aluminum brightwork add to some sportiness from the cockpit view, as well.
