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 offers to buy back new diesels if bans introduced

By Maria Sheahan FRANKFURT, Germany — Volkswagen will buy back new diesel cars if German cities ban them, it said on Thursday, seeking to reassure potential buyers and stem a plunge in sales of diesel vehicles. Europe's biggest automaker also said it would extend incentives for buyers of new diesel cars. The moves come after a German court ruled last month that cities in the country could ban the most polluting diesel vehicles from their streets. Many German cities exceed European Union limits on atmospheric nitrogen oxide, known to cause respiratory diseases. Fears of bans have led to a plunge in demand for diesel vehicles, which are also key to carmakers' attempts to meet new EU rules on carbon dioxide (CO2) emissions. While diesel cars are heavily criticized for emitting nitrogen oxide, they spew out less CO2 than gasoline equivalents. Diesel car sales plunged 19 percent in Germany last month. At its core VW brand, Volkswagen said its buyback offer applied to new diesels bought between April 1 and the end of 2018 and would kick in if the city in which the buyer lived or worked banned diesels within three years of the purchase. It said its dealerships would buy back diesel vehicles affected by bans at their current value if their owners at the same time bought a new vehicle that was not affected by cities' driving restrictions. At Czech brand Skoda, the guarantee applies to cars bought between April 1 and the end of June, but will cover bans introduced within four years of the purchase date. At premium brand Audi, the offer only covers leased vehicles. Volkswagen also said it was extending to the end of June incentives for customers trading in older diesels for new ones. Fellow German carmaker BMW said earlier this month it would offer to take back leased vehicles if diesels were banned within 100 kilometers (62 miles) of the operator's home or place of work. There has been a global backlash against diesel-engine cars since Volkswagen admitted in 2015 to cheating U.S. exhaust tests. But Germany's government is seeking to avoid widespread bans on heavily polluting diesel vehicles, which companies say could cut the resale value of up to 15 million vehicles in Europe's biggest car market. In Germany, where motorists expect to drive powerful cars on motorways with no speed limits, any restrictions will be unpopular.

Ferdinand Piech (1937-2019): The man who made VW global

Towering among his peers, a giant of the auto industry died Sunday night in Rosenheim/Upper Bavaria, Germany. Ferdinand Piech, a grandson of Ferdinand Porsche, who conceived the original Volkswagen in the 1930s, was the most polarizing automotive executive of our times. And one who brought automotive technology further than anyone else. Ferdinand Porsche had a son, Ferdinand (called "Ferry"), and a daughter, Louise, who married the Viennese lawyer Anton Piech. They gave birth to Ferdinand Piech, and his proximity to two Alfa Romeo sports cars — Porsche had done some work for the Italians — and the "Berlin-Rome-Berlin" race car, developed by Porsche himself, gave birth to Piech's interest in cars. After his teachers in Salzburg told his mother he was "too stupid" to attend school there, Piech, who was open about his dyslexia, was sent to a boarding school in Switzerland. He subsequently moved on to Porsche, where he fixed issues with the 904 race car and did major work on the 911. But his greatest project was the Le Mans-winning 917 race car, developed at breathtaking financial cost. It annihilated the competition, but the family had had enough: Amid growing tension among the four cousins working at Porsche and Piech's uncle Ferry, the family decided to pull every family member, except for Ferry, out of their management positions. Piech started his own consultancy business, where he designed the famous five-cylinder diesel for Mercedes-Benz, but quickly moved on to Audi, first as an engineer and then as CEO, where he set out to transform the dull brand into a technology leader. Piech killed the Wankel engine and hammered out a number of ambitious and sophisticated technologies. Among them: The five-cylinder gasoline engine; Quattro all-wheel drive and Audi's fantastic rally successes; and turbocharging, developed with Fritz Indra, whom Piech recruited from Alpina. The Audi 100/200/5000 became the world's fastest production sedan, thanks to their superior aerodynamics. Piech also launched zinc-coated bodies for longevity — and gave diesel technology a decisive boost with the advent of the fast and ultra-efficient TDI engines. Less known: Piech also decided to put larger gas tanks into cars. Customers loved it. Piech's first-generation Audi V8 was met with derision by competitors; it was too obviously based on the 200/5000.
