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.

2015 Audi A8 rises to meet the challenge [w/video]

It's turnover time in the extra large premium sedan segment. With Mercedes having stuffed HAL 9000 in its new S-Class, other luxury marques are quickly updating their own super sleds to keep up with this persistent march of technology. While far from a full redesign, the Audi A8 has changed enough for 2015 in terms of styling, powertrains and new technology to keep it in the conversation.
For starters, the A8's exterior design has been redone, with the most noticeable changes happening up front. The trademark 'gaping maw' grille is a little less gaping, while the headlights now feature a straight lower edge of LEDs, excising the old model's droopy-eyed look. Speaking of headlights, Audi now offers optional Matrix LEDs, the latest in headlight tech, with 25 individual elements per side that can be turned on or off and dimmed as the situation demands. The rear of the A8 has also been resculpted and looks very much inspired by the derrière of the A7, with a single chrome strip connecting the new LED taillights.
The A8's full suite of powertrains has also been upgraded, with the supercharged 3.0-liter V6 now producing 310 horsepower (up 20 according to Audi, though down 23 compared to the US-spec 2013 model). The twin-turbo 4.0-liter V8 is now rated at 435 hp, a solid 20-horse increase that lowers the car's 0-62 time to just 4.5 seconds. That's within spitting distance of the 520-hp S8's time of 4.1 seconds. That aforementioned super sport sedan's engine remains unchanged, as does the 6.3-liter 12-cylinder powerplant in the A8 L W12, but Audi's two diesel engines have both improved, with the 3.0-liter V6 producing an extra eight horsepower (256 total) and the 4.2-liter V8 gaining an extra 34 hp (385 hp) to go along with its more-than-adequate, though unchanged, 626.93 foot-pounds of torque.

German prosecutors have recorded calls between VW bigwigs talking dieselgate

It's barely possible to believe how poorly Volkswagen continues to handle dieselgate. Depending on which day you catch the news, the German carmaker embodies the corporate venality of "Michael Clayton," the comic blundering of the Coen Brothers' "Burn After Reading," and the every-man-for-himself vengeance of "Reservoir Dogs." Today is Tarantino day, with news that German prosecutors have recordings of phone calls between former Audi and Porsche development boss Wolfgang Hatz, ex-Volkswagen Group executive Matthias Muller, and current Porsche executives Oliver Blume and Michael Steiner. Hatz made the calls to the trio in November 2015, two months after Volkswagen admitted its diesel-particulate sins to the U.S. Environmental Protection Agency. Hatz was still employed at the time, and in his company car. Who recorded the calls? His wife. Hatz and his missus apparently saw the storm coming and started stacking defenses early. Hatz's wife, who can be heard encouraging Hatz during at least one call, sent the recordings to Hatz's attorney from her mobile phone. According to a Google translation of the German newspaper Handelsblatt's report, she included the note, "Here is a very long, but quite informative conversation on the current situation with useful formulations." The report in Handelsblatt said that in Germany it is generally "not allowed" to record a conversation and pass it on to a third party. We don't know how the authorities will handle this matter, since prosecutors found the recordings in e-mail attachments on Mrs. Hatz's mobile phone. Remember, when the diesel scandal broke, VW spent months saying that only a small number of low-level personnel were behind it, and all of the higher-ups had been blindsided. Ex-CEO Martin Winterkorn claimed to be "stunned that misconduct on such a scale was possible in the Volkswagen Group." Winterkorn successor Matthias Muller said, "according to current information, a few developers interfered in the engine management." Former VW USA honcho Michael Horn told a congressional committee that "a couple of software engineers" programmed the software for reasons no one could understand. In the recorded conversations, Hatz apparently called Muller to find out how VW planned to treat him.
