Audi confirms S8 Plus for US to debut in LA

Audi has confirmed that the new S8 Plus will indeed be coming to North America. The more potent version of the German automaker's flagship sedan was first revealed in August, and Audi will bring it to the upcoming Los Angeles auto show. The Plus model packs the same 4.0-liter twin-turbo V8 as the existing S8 (and the Bentley Continental for that matter), but increases output from 520 horsepower to 605 hp and torque from 481 pound-feet to 516 lb-ft (or 553 on overboost). The result is a 0-62 time quoted at 3.8 seconds to give the likes of the Mercedes-AMG S63, Jaguar XJR, and Maserati Quattroporte a run for their money. Audi of America has not announced US pricing for the S8 Plus or final specifications for the American market. Look for an MSRP in the neighborhood of $140k. The Audi S8 Plus will debut in LA alongside the new RS7 Performance and the second-generation R8, which will be making its US auto show debut at the SoCal expo. TRIO OF AUDI SPORT® AND PERFORMANCE MODELS TO MAKE US DEBUT AT LA AUTO SHOW – AUDI R8, RS 7 PERFORMANCE AND S8 PLUS - The second generation of the R8 high-performance halo car makes its U.S. auto show debut - Auto show debut of new RS 7 performance enhances brand's dynamic profile - S8 plus strengthens Audi's position in premium sedan segment November 10, 2015 | HERNDON, Virginia -- Reinforcing the brand's success from road to track, Audi will showcase a trio of new performance vehicles – including the all-new R8, RS 7 performance and S8 plus – at the Los Angeles Auto Show. "The Audi Sport® and performance models have always been an essential part of our brand's character," said Filip Brabec, Director of Product Management for Audi of America. "The Audi R8, RS 7 performance and S8 plus represent the maximum of Audi performance, premium design and technology for our customers." 2017 Audi R8 The fastest and most powerful Audi of all time, the 2017 R8 represents the pinnacle of performance for any model with the four rings. Thanks to the close cooperation between Audi Sport® engineers, race drivers and developers, the Audi R8 and R8 LMS racecar were co-developed and share approximately 50 percent of the same parts, including the V10 engine. The R8 launches with two powertrain variants: the 5.2L V10 with 540 hp, an increase of 15 hp from the previous R8 model or the R8 V10 Plus, boasting a powerful 610 hp, an increase of 60 hp, making it faster, more powerful and more dynamic than its predecessor.

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 to lap Hockenheim in driverless RS7

An automaker like Audi will always have a number of different research and development projects going at the same time, and some of them might take on very different approaches. At one end, you'll have its racing programs, and at what you'd assume would be the other, self-driving prototypes. But Ingolstadt is preparing to bridge that gap by running an autonomous prototype at racing speed around the famed Hockenheimring.
Set to take place on Sunday, October 19, during the DTM season finale at Hockenheim, the driverless RS7 will motor at speeds up to 150 miles per hour, right up "to its physical limits with millimeter precision."
Audi anticipates that "the world's sportiest piloted driving car" will run a lap time of just over two minutes, at which the RS7 would stand not only to be the fastest driverless car ever to lap the circuit, but also potentially the fastest four-door - if it can beat the 2:02.71 lap time set by a BMW M3 sedan in 2007.
