Audi replaces Mercedes as official vehicle supplier to the IOC

The automotive sponsor of the International Olympic Committee for the past 22 years has been Daimler-Benz. No more, as Audi has just signed a four-year deal to be the official auto supplier to the folks who keep the torch alight and on the move. Audi will supply vehicles for the IOC's headquarters in Lausanne, Switzerland and the organization's international events.
In case you're remembering all the stories about BMW and the London Olympics last summer and wondering where Mercedes-Benz was in all of that, the answer lies in the numerous mouths at the Olympic trough. The IOC is the organization and oversight body of the Olympics - much like the way the FIA oversees world motorsport. BMW, though, sponsored the London Organizing Committee for the Olympic Games, so during the games IOC reps rode in Benzes, LOCOG and its guest dignitaries rode in BMWs.
The Volkswagen Group has other ties with the Olympics as well: The Group will be the official vehicle partner for the winter Olympics in Sochi, Russia in 2014, and Audi currently partners the national Olympic federations of Germany, Finland, Russia and Switzerland. The press release below announcing the partnership has all the official details.

VW recalls 220,000 Atlases, Atlas Cross Sports for airbag defect [Updated]

[Update: Audi of America has confirmed that no U.S. models are among the recall population for plug-in hybrid fire issue.] Volkswagen has issued yet another recall for its Atlas SUV, this time for side airbags that may not deploy correctly in an accident due to a problematic connection in one of the vehicle's wiring harnesses. The campaign covers 222,892 Atlas and Atlas Cross Sport models built for the 2019-2023 model years.  The issue stems from a connection with the wiring harness that runs from the A-pillar into the door. VW says that harnesses produced by one of its suppliers were not built with additional measures to prevent movement at the connection point. Small movements can cause abrasion of the metal contacts which could lead to a whole host of electronic misadventures, including the potential for airbag deployment to be delayed in a crash.  "Micro-movement of the wire harness (terminal A-Pillar to front door) can result in damage to the wire terminal surface. Damage to the surface can [result] in fretting corrosion which may cause sporadic interruption in the electrical connection to the components of the front door," VW said in its defect notice. "The airbag warning light may illuminate if a malfunction is detected. Other symptoms of a sporadic interruption of the affected electrical connection can be: inadvertent rolling down windows, inadvertent park brake engagement at low speeds (below approx. 3km/h or 1.8mph), warning regarding faulty door sensor," VW said.  Not every model built within the range defined above is subject to the recall; terminals from other suppliers were manufactured with the necessary safeguards in place. If you own a 2019-2023 Atlas or Atlas Cross Sport, keep your eyes peeled for a notification from VW regarding the campaign, likely some time in early-mid May.  PHEV problems Across the Atlantic, the VW Group mothership confirmed that it will recall more than 100,000 plug-in hybrid models worldwide to address a fire risk. The recall was launched in response to 16 reported incidents of fires stemming from insufficient insulation of the PHEV battery pack that allows the engine cover to make contact if it is not completely secure. If that happens, the heat from the battery can ignite the engine cover. The recall will cover PHEVs build by VW, Audi, Seat and Skoda, Reuters reports, including the VW Passat, Golf, Tiguan and Arteon — plug-in variants of which are not sold in the United States.

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.
