Audi considering other variants, turbo V6 for R8

More details from the Audi R8 event at Spain's Ascari circuit have met the Internet, and they provide more intel on the supercoupe will evolve over the second generation. First, they note some small differences in stance with this new car, being wider than the current car and sitting 30 millimeters (1.18 inches) lower. Compared to its Lamborghini Huracan brother, it gets three extra centimeters in the wheelbase. Filling out the power numbers, the 'entry-level' V10 engine at launch rolls out 540 horsepower and 399 pound-feet of torque, does the 0-60 mile per hour dash in 3.5 seconds, and hits a top speed of 200 mph. The V10 Plus model rocks 620 hp and 412 lb-ft, which slices 0.3 seconds off that acceleration time and adds five more mph to the top speed. They'll transfer their power through a seven-speed S-tronic that shifts faster than before, and it will in turn send power through an electronically-controlled clutch at the front axle and a constantly variable limited-slip differential at the rear axle. The power split is said to default to 42/58 front-to-rear, but 100 percent of the torque can be sent fore or aft. Benchmarked against the 991-series Porsche 911, driving sensations travel through an electromechanical steering setup that can be had with a variable rack if preferred, leading to standard 19-inch wheels with the option of 20-inchers and tires developed specifically for this car. A Performance setting offers dry, wet, and snow modes; that first setting turns the ESC off except for situations of impending doom, and Audi racer and test driver Frank Stippler told Top Gear that understeer is reduced, to which TG added "it oversteers at will." Stippler said it's "a lot closer to the GT3 race car than ever before," and even though it's "a lot" less intense than the Huracan, it's just as fast on the track. His estimate is that the new R8 will lap the Nurburgring between ten and 15 seconds faster than the current car. R8 technical lead Roland Schala said the new chassis opens up new avenues of development because "there's no problem to change it," mentioning models like a Clubsport or Superleggera as no longer forbidden. Differentiation could come from a wider engine mix, too. Markets like China need smaller displacements, so Audi's twin-turbo V8 is expected to join the line-up at some point, bringing 500 horsepower.

Audi on Demand pilot program launches in San Francisco

Customers eager to drive a new Audi but unwilling or unable to plunk down the purchase price for one will be intrigued by the launch of the new Audi on Demand program. Initially being rolled out in San Francisco, Audi on Demand is based around an iPhone app that allows clients to order up a new Audi of their choosing on a day-by-day basis for up to 28 days in a row. Order an Audi through the app and a "personal concierge" will deliver the car anywhere in the city – curbside, driveway, parking lot, office building... pretty much anywhere the customer chooses. The concierge will even help set up the audio and navigation systems to the customer's preferences. And if the customer isn't there to receive the vehicle in person, he or she can simply unlock it through the app, start it up and drive off. The service is being made available on a broad range of Audi models, from the A4 all the way up to the R8. Customers can even specify a child seat or (on an Allroad or Q5) a ski or bike rack, and are guaranteed that the vehicle they select will be the one they get, right down to the color and trim. Though being launched at first only in San Francisco, Audi says it will roll out the program in other American cities "in the coming years." In announcing the program, Audi also revealed that it's planning to launch Audi at Home as well, a "micro-sharing" service that will allow residents of select condo complexes to share a fleet of Audis as well. These, of course, are just the latest smartphone-enabled conveniences being introduced by the German automaker, following its collaboration with Amazon and DHL for in-trunk delivery.

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.
