Next Audi R8 caught on the 'Ring

Now that we're kinda-sorta-maybe-slowly thawing out from this horrible winter, automakers are moving away from the harsh extremes of winter testing and taking their new wares for laps around the infamous Nürburgring. What better way to kick off the sports car testing season than some fresh shots of the next-generation Audi R8 supercar?
Despite the slick coupe's shape not changing too much, details under that camouflage reveal styling elements that are more squared off and angular - similar to what Audi has done with its 2015 TT coupe. Don't be fooled by those square taillamp holes in the camo out back, either - look closely and you'll see a stylish LED lamp design.
Expect some 100 to 200 pounds to be shaved off the next R8's curb weight.

Ten of the greatest Super Bowl car commercials of all time

With an average of over 100 million viewers each year, the Super Bowl always has advertisers bringing out the big guns. And for those among us who don't know the difference between a safety and a touchback, those commercials can be one of the most compelling aspects of the annual ritual. Car companies, in particular, have a long history of making the most of the huge Super Bowl audience by debuting some of the most memorable advertisements that have ever aired on television. So, in preparation for the new batch we'll be seeing this coming Sunday, here's a collection of our favorites from the past. 10. Audi – The Godfather When Audi created this homage to the quintessential gangster movie to promote its newest sports car, the company managed to make a commercial that was simultaneously funny, a little bit disturbing, and most importantly memorable. 9. Maserati – Strike This one might start out slow, but it delivers not only with the wicked sound of the third-generation Ghibli's engine, but with an interesting message about hubris in the auto industry as well. 8. Nissan 300ZX Twin-Turbo – Dream Directed by none other than Ridley Scott (Blade Runner, Alien), this dystopian spot has centers around a narrator who explains that in his dream the bad guys are unable to catch him despite their best efforts by way of street bikes, race cars, and supersonic jets. While the twin-turbocharged 300ZX car was certainly a performance powerhouse to be reckoned with in its day, the concept and execution of this one does come off a little bit campy now – but in a good way. Then again, it is a dream, after all. 7. General Motors – Robot This one is unique in that it's genuinely depressing on a profound level. Who would've thought that the simulated suicide of a lovable, anthropomorphic car-building robot who has fallen on hard times could be such a downer? 6. Nissan – With Dad Although the debut season of its new LMP1 racer didn't exactly turn out how the team hoped it would, there's no denying that Nissan's depiction of a strained father-and-son relationship that eventually leads to redemption (and the introduction of the 2016 Maxima) tugs at the heartstrings. 5. Volkswagen – Big Day A surprisingly poignant advert, this one might be low on dialogue but it certainly gets its message across. And just as the dramatic soundtrack begins to lull the viewer into a sense of security, our expectations are upended. 4.

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.
