Audi TT Quattro Sport Concept takes the next-gen to the extreme

There's little doubt that the new Audi TTS and its 310-horsepower, 2.0-liter, turbocharged four-cylinder will be very quick when released to the general public. As a means of reminding us that Audi can do much more with the little TT, though, the German manufacturer has presented this, the TT Quattro Sport Concept, alongside its litter of new sports cars.
Complete with a 420-horsepower, 2.0-liter, turbocharged engine - yes, it really puts out 210 horsepower per liter - the TT Quattro Sport can snap to 62 miles per hour in just 3.7 seconds. 331 pound-feet of torque is also on offer, meaning this one-off TT outguns the TTS by 110 horsepower and 51 pound-feet of torque.
An S-Tronic transmission shuffles the power about, while the car itself rides on a lowered and stiffened suspension. 20-inch alloys are featured with centrally locking, racing-style hubs. Those racy wheels are housed in wells that have had their arches stretched an additional 1.18 inches, which, along with the lowered suspension, contribute to the TT's aggressive looks.

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.

Feds allege widespread Volkswagen cheating on clean-air rules

Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the federal government charged Friday. The Environmental Protection Agency issued a notice of violation to the German automaker, saying the company's software broke the law by violating two provisions in the Clean Air Act. Circumventing the standards meant affected cars emitted as much as 40 times the allowable level of certain pollutants. Both the EPA and California Air Resources Board have launched investigations. In its notice of violations, the EPA said Volkswagen officials admitted to installing and concealing what they call a "defeat device," which was designed to detect when the cars were undergoing official emissions tests – and only turn on emissions controls during that time. "Our goal now is to ensure that the affected cars are brought into compliance, to dig more deeply into the extent and implications of Volkswagen's efforts to cheat on clean air rules, and to take appropriate further action," said Richard Corey, executive officer of CARB. The allegations cover approximately 482,000 vehicles sold in the United States over the past seven years. Cars involved include diesel versions of the Jetta, Beetle, Audi A3 and Golf manufactured between the 2009 and 2015 model years. Passats manufactured for the 2014 and 2015 model years are also included. Federal officials note there is no safety danger to motorists, but the cars will be recalled for repairs. If true, Volkswagen faces a fine that could run in the hundreds of millions of dollars -- likely higher than the $300 million charge the EPA levied last November at Hyundai and Kia for exaggerating the fuel-economy in several models. The charges also put a tremendous dent into the company's plans to increase sales of its "Clean Diesel" vehicles in North America. In a written statement, Volkswagen Group of America acknowledged it had received the notices from the EPA and CARB. "VW is cooperating with the investigation; we are unable to comment further at this time," it said. Federal officials said the defeat-device software was uncovered during an independent analysis by researchers at West Virginia University, who in working with the International Council on Clean Transportation, a non-governmental organization, raised questions about emissions levels.
