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.

1,682 miles in a 2014 Audi A8 L TDI - Part 2

Interruptions like the Canadian Grand Prix, Le Mans, Pikes Peak, that ridiculous Porsche 911 GT3 and the really good, really outrageous Jeep Cherokee, are among the distractions that delayed the conclusion of this tale. If you'll remember, in Part 1 we started off in a parking lot in Sebring with an Audi A8, headed anywhere that would empty our tank, and after five days in Miami and Ft. Lauderdale and Pompano Beach we bolted in the middle of the night for a breakfast date at an IHOP a couple hundred miles away.
We last left proceedings at a Chevron pump beside the West Florida Turnpike, somewhere around midnight in the humid wilds, having done 660 miles and spent $89.40 to put 20.992 gallons in the great white whale. We had done average speed of 31 miles per hour at an average rate of 27.5 miles per gallon. Those kinds of numbers, as we demonstrated, are good enough to put you in the fuel economy orbit of the Toyota Corolla - to be precise, it only cost $6.40 more to cover that 660 miles in the A8 TDI than it would in the Japanese compact. That led us to conclude that there were just a couple of Starbucks Venti lattes between the A8 and the Corolla, assuming we conveniently ignore the two cars' purchase prices. Turns out we were wrong: it didn't take long for a commenter named "mike" to set us straight when he wrote, "It's clear you weren't lying about not frequenting Starbucks...no way could you get two venti lattes for $6.40." Mike, we salute you - our ignorance of terrible coffee has served the higher purpose of emphasizing the strong case made by the diesel Audi.
But that A8... well, the wheels were still on the damn thing and we had to drive them off. That meant five more days of pilot duty to get us from wherever the hell we were to Wildwood and Daytona Beach, FL, then Brunswick, Macon and Atlanta, GA, then Birmingham, AL, and back to Atlanta.

Audi UK in hot water over dealer safety claims

Car salesmen don't exactly have a reputation for being in the most truthful profession, and it appears that several Audi showrooms in the UK are playing into that stereotype. A BBC investigation found that multiple dealers told buyers that the company's models scored well in Euro NCAP crash tests. No big deal, right? The problem was that the vehicles were never actually evaluated.
The report began after an R8 buyer sent in a tip that his UK dealer claimed the sports car had received top Euro NCAP scores. However, it has never been tested by the organization. The BBC called 10 dealers inquiring about the A5 (pictured above), which also wasn't assessed. Nine said the coupe had been checked out, and six claimed it had a five-star rating - the best available.
Euro NCAP is funded by governments and motoring bodies, like the ADAC in Germany and the FIA. According to its website, the organization selects some of the most popular new models each year to crash test, and, the BBC claims, automakers can also pay to evaluate their cars. The last Audi tested was the A3 in 2012. The A6, Q3, A1, A4 and Q5 have also been tested since 2009, and they all received five-star ratings. However, the A5, A7, A8 and R8 have not been tested.
