VW says it has sold over 100,000 TDI diesels in America this year

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here - perhaps not surprising when the two brands offer a total of 12 diesel models.
What might be surprising is that the number of diesels isn't far off the estimated sales of 90,000 battery electric vehicles and PHEVs, with 15,000 of those accounted for by the Tesla Model S, another 12,000 or so being the Toyota Prius PHEV.
VW's keen to play up the ease of making diesel part of your life, stressing that it doesn't need any change to the refueling infrastructure and that "this is a technology delivering real answers to society's concerns about fuel consumption and greenhouse gas emissions without compromises."

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

Watch the Chevy Corvette dismiss its Euro rivals at the hands of a Brit magazine

European auto writers, especially the British, have a bit of a reputation for favoring their own domestic cars over foreign rivals in comparison tests. Just think about how many times you've heard Jeremy Clarkson deify the latest product of UK loins while denigrating an American rival as a hopeless "Yank Tank." However, we have to tip our hats to the folks at Autocar because in its latest video comparing the 2014 Corvette Stingray to the Porsche 911, Jaguar F-Type V8 S and Audi R8, it's actually given the Vette a fair shake.
Autocar has put the Stingray through a battery of tests against what it considers to be the three best sports cars on sale in Europe today. And while the tests that it has chosen are somewhat random and subjective, it has concluded that the C7 can stand up against its rivals, even irrespective of its price. It's one thing to hear about how great the Stingray is from American writers, but it's great to know that not all Brits think we've gone crazy for calling the new Chevrolet "exquisite."
