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 already teasing, testing next R18 e-tron quattro

You can't debate Audi's record in endurance racing. With 12 victories at the 24 Hours of Le Mans, it comes second only to Porsche in the history books of the famous endurance race - only in Audi's case, all of those victories have come in the last 14 years, losing only twice: once to its partner team Bentley in 2003 and once to rival Peugeot in 2009. It's won the FIA World Endurance Championship in both of the seasons it's run so far, and has won championships in the European and American Le Mans Series, too.
That's quite a record to defend, and defend it Audi will with an evolved LMP1 racer next year. Only a week after tying up its second consecutive world championship, the German outfit is already back at Sebring this weekend testing the successor to the all-conquering R18 e-tron Quattro. Unfortunately as the new United SportsCar Championship doesn't include LMP1s, the only chance we may have to see it competing here in the United States will be at the 6 Hours of the Circuit of the Americas in September.
Audi is keeping mum on the details for the time being, releasing only this one photo and promising to reveal further details before the end of the month, but we can already discern a more streamlined shape, revised aero and reprofiled headlamps among the changes from the outgoing R18. One way or another, with Toyota upping its game and Porsche returning to top-level competition next season, Audi may be in for its toughest challenge yet - but you can bet it won't take it lying down. Scope out the press release below and watch this space for more.

Felicity Ace sinks with thousands of VWs, Porsches, Lamborghinis

The stricken ship Felicity Ace sank overnight after a week of salvage efforts ultimately proved unsuccessful. The ship, which was carrying up to 4,000 VW Group cars, went to the bottom unexpectedly while a salvage team was attempting to tow it to shore, Bloomberg reports.  "Initial reports from the local salvage team state that the vessel had sunk at around 9AM local time having suffered a list to starboard," Mitsui O.S.K. Lines transportation company (MOL), which owns the Felicity Ace, said in a statement released early Tuesday.    "The last vessel position was around 220nm off the Azores," MOL said. "The salvage crafts will remain around the area to monitor the situation. Further information will be provided as it becomes available." The ship sank after being battered by waves and listing 45 degrees to starboard, the ship’s operator said. “The weather was pretty rough out there,” Pat Adamson, a spokesperson for MOL Ship Management (Singapore), a unit of Mitsui OSK Lines Ltd., said by phone. “And then she sank, which was a surprise.” VW, Porsche, Audi, Bentley and Lamborghini-branded models were aboard the ship, which was headed to Rhode Island from GermanyÂ’s Emden port when the fire broke out on Feb. 16.  Rough seas and ongoing fires fueled by the lithium-ion batteries of EVs onboard delayed the ship's salvage and recovery operations for the better part of a week. While the likelihood of salvaging the smoke and potentially fire- and water-damaged vehicles from Felicity Ace's hold was slim to none, some had held out hope that their special-ordered vehicles might survive the mishap.  The Panama-flagged Felicity Ace was safely evacuated of its 22 crew members by the Portuguese navy after a fire started in its hold more than a week ago. The ship can carry up to 4,000 cars. European carmakers declined to discuss how many vehicles and what models were on board, but it appears to have been transporting approximately 2,500 cars, including roughly 1,100 Porsches and an undetermined number of Volkswagens.  The cars aboard were on order. Porsche customers in the United States were being contacted by their dealers, the company said. “We are already working to replace every car affected by this incident and the first new cars will be built soon,” Angus Fitton, vice president of PR at Porsche Cars North America, Inc., told The Associated Press in an email. The ship sank in water nearly 10,000 feet deep, the Portuguese Navy said.
