Winterkorn vacates chairs on Audi, Truck & Bus boards

The last remaining vestiges of Martin Winterkorn's power within the Volkswagen Group are slowly melting away. The former chairman of the group's management board resigned as CEO nearly two months ago in the wake of the diesel emissions scandal. He held onto other roles within the group, but one by one he's been vacating those as well. Last month Winterkorn resigned from his role at Porsche SE – Volkswagen's largest shareholder. Now the latest development comes from Bloomberg, which reports that Winterkorn has stepped down from his role as chairman of the supervisory board at Audi. Prior to his promotion to run the entire group, Winterkorn served as chief executive of the Audi division, and prior to his resignation served continued to serve as its board chairman. No date was given for his resignation from that capacity, nor any successor named at this point. Repeated requests for clarification from Audi have gone unanswered. In correspondence with Autoblog, however, spokespeople for VW's commercial vehicle operations confirmed that Winterkorn has also stepped down as the chairman of the board at Truck & Bus GmbH. The newly established division encompasses truck manufacturers Man and Scania. Winterkorn also served as chairman of Scania's board, but requests for confirmation of his departure from that role also went unanswered. The Swedish truck manufacturer, however, named Henrik Henriksson as its a new chief executive only a few days ago.

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.

Audi reveals next-gen TT interior at CES

Audi has taken the somewhat unusual step of unveiling much of the interior of its upcoming TT Coupe at the 2014 Consumer Electronics Show in Las Vegas. That's unusual, because they haven't shown us the car yet. Perhaps we shouldn't be surprised - with the proliferation of technology in automobiles these days, it's probably time we start considering them as much electronic devices as transportation devices.
While Audi has long been recognized as a leader in interior design, this new TT features an instrument cluster that is wildly different from what we've become accustomed to from the Four-Ring brand. Audi is calling its fully digital system a "virtual cockpit," and with its 12.3-inch LCD screen situated directly in front of the driver, it does away with the company's traditional Multi-Media Interface (MMI) display in the center stack. Two modes are offered, one classic option with large gauges and another more oriented to infotainment.
Besides electronics, the actual hard parts of the interior also show plenty of new thinking. With the removal of the central screen, Audi has been able to streamline its instrument panel to resemble a wing of sorts, with jet-like HVAC vents that house their own controls. Two more points for controls are presented to the driver, with buttons on the flat-bottom steering wheel and another set on the center tunnel.
