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.

Weekly Recap: Car-pedestrian crashes remained elevated in 2014

The death of American Horror Story: Freak Show star Ben Woolf served as a reminder this week that car crashes involving pedestrians remain a problem, and a new study issued on Thursday reinforced that the situation isn't really getting better. The Governors Highway Safety Association found a slight decline, 2.8 percent, in the number of pedestrian deaths in the first six months of 2014. Fatalities dropped from 2,141 to 2,125 compared with the same period in 2013, though the association says it's a statistical wash when factoring in undercounting. Deaths are still 15-percent higher than in 2009. "The number of deaths remains relatively high and is cause for concern," wrote Allan Williams, who compiled the report and is the former chief scientist at the Insurance Institute for Highway Safety. This is the first look at data from last year, and the National Highway Traffic Safety Administration will issue its full-year results later. The GHSA found some progress on the roadways, as 24 states and the District of Columbia reported drops in pedestrian deaths. In some states, the problem isn't even a problem at all: Nebraska and Wyoming reported one fatality apiece, though large population centers in urban areas are where most accidents occur. "This is a clearly a good news, bad news scenario," Jonathan Adkins, GHSA executive director, said in a statement. "While we're encouraged that pedestrian fatalities haven't increased over the past two years, progress has been slow." Other News & Notes Cadillac previews CT6 during Oscars Cadillac previewed its upcoming flagship sedan, the CT6, in commercials that aired Sunday during the Oscars. As expected, the creased sedan carries on Cadillac's recent design language, and the car in the commercial looks like a larger version of the CTS and ATS sedans. The CT6 will be revealed this spring at the New York Auto Show and launch late this year. It will be assembled at General Motors' Detroit-Hamtramck factory on a rear-wheel-drive chassis, and the CT6 is the first car to use Cadillac's revised alpha-numeric naming scheme. The commercials also kicked off Cadillac's "Dare Greatly" campaign, which is the first with its new advertising agency, Publicis Worldwide.

Audi mulling producing version of Quattro showcar, just not sure which one [w/poll]

Head of design for Audi, Wolfgang Egger, has told Auto Express that a reborn Quattro could enter production, but bosses for the company haven't yet decided whether to base it on the Sport Quattro concept that just debuted at this week's Frankfurt Motor Show or the smaller Quattro concept that was revealed at the 2010 Paris Motor Show.
While both draw their inspiration from the original Ur-Quattro of the 1980s, they vary wildly in both size and choice of powertrain. The 2010 Quattro concept was based on Volkswagen's MQB platform, shared with such vehicles as the Golf and Audi A3. The Sport Quattro, meanwhile, was built atop the company's larger MLB platform that's used almost exclusively for Audi models, including the A5, which is also a coupe.
Under their hoods, the 2010 Quattro concept simply employs a version of the same 2.5-liter engine used in the TT RS, tuned to deliver 408 horsepower, while the Sport Quattro goes nuclear with a twin-turbo V8 hybrid powertrain that develops 700 hp and 590 pound-feet of torque. Both, of course, employ quattro all-wheel drive just like their forebearer.
