Audi reveals updated RS7 Sportback in Europe

It was just a couple of weeks ago that Audi revealed a few mild updates to its A7. It even ported those changes over to the warmed-up S7 performance version. All that was missing was the full-steam RS7, and that's precisely what we have here.
Now before you get all excited, note that the new RS7 packs the same powertrain as the model it succeeds, but then again, the existing RS7 hardly lacked in the power department. The 4.0-liter twin-turbo V8 still churns out 560 horsepower and 516 pound-feet of torque, transmitted to all four wheels through an eight-speed automatic. Revealed initially for the European market (with US details presumably to follow), the 0-62 kilometers per hour time is quoted at 3.9 seconds, so the 0-60 mph time ought to match the 3.7 seconds of the preceding model.
What has changed are the subtle tweaks Audi has made to the exterior and equipment upgrades inside. The grille now features has a horizontal section at the bottom with the Quattro logo emblazoned across like all other recently revised RS models, flanked by new headlights (Matrix LED units for the European market). Inside the cabin the air-con vents and shift paddles have been reshaped, and the new MMI system ports over from the new A7 and S7 with 4G LTE connectivity and a Bang & Olufsen sound system.

The Volkswagen Group switches official language to English

The Volkswagen Group can't be fairly thought of as entirely German anymore, so the news that the company is switching its official language to English to help attract managers and executives is a rational, if surprising, decision. While many VW Group companies are still staidly German in character and culture, consider the other companies that it controls: Bentley (British), Bugatti (French), Ducati and Lamborghini (Italian), Skoda (Czech), Scania trucks (Swedish), and SEAT (Spanish). Not to mention the large Volkswagen Group of America operation, which constructs cars in Chattanooga, TN. Volkswagen's explicit motivation is to improve management recruitment – making sure the company isn't losing out on candidates for important positions because they can't speak German – and that's inherently sensible in a globalized economy. Particularly considering, like it or lump it, that English is the lingua franca of said global economy. It also should make it inherently easier to communicate between its world-wide subsidiaries and coordinate operations. It's hard to say for sure if this will have any impact on the consumer, although it's easy to see the benefits if, say, VW Group hires some American product planners or engineers and they push for features and designs that more closely suit American needs. After all, the US is a hugely important market for any manufacturer, and so the switch to English almost certainly has something to do with the outsized influence of the US in the global economy. And there doesn't seem to be a downside from a purely rational perspective, although it could mean that the Group's corporate culture becomes less German. Whether that's a good or a bad thing depends on your perspective.

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.
