Audi Sport is actually a thing, and it's set to fight BMW M, Mercedes-AMG 

"Essentially, the name Audi Sport positions an enterprise already used to become better-recognized by the public and sets itself up to grow as a result." BMW has its M performance subsidiary. Mercedes-Benz has AMG. So what does Audi have? Some would say "nothing," a few would answer "Quattro," while many others would respond to that by saying, "Don't be stupid, Quattro's their all-wheel drive system." Well, it is, but Quattro GmbH is also the name of the company that has been tasked with creating Audi's highest performance cars, plus special-order customization, customer racing, and the Audi Collection of merchandise. Trouble is, nobody really knew that, as it was in no way a public-facing brand. That all changes with the entity now rechristened as Audi Sport. It doesn't stop there. "We wanted to have recognition for the R8 and RS models on a broad level," said Filip Brabec, vice president of product development. Audi Sport allows those models to be more easily identified as something different and special, much as AMG models are. "It's not just a piece of marketing material, but it'll also be recognized at a dealership." Around half of Audi dealers in the United States have signed up to be Audi Sport dealers, granting them unique training, access to track events and signage. The dealer buildings themselves will have special areas devoted to Audi Sport. So essentially, the name Audi Sport positions an enterprise already in use to become better-recognized by the public and sets itself up to grow as a result. But be it called Quattro GmbH or Audi Sport, what is it that they exactly do? Besides the R8, which it completely developed and manufactures, all its RS models are done in concert with Audi AG. Yet, that "done in concert" process has changed a bit over the years and head of Audi Sport product development Stefan Reil has been there from the RS cars' beginning 19 years ago. "When we started, our cars were launched in the last one or two years of the base Audi cars," Reil said. "We started development when the base cars were already in development or on the road. Now we have a much closer interaction with the people at Audi AG. Even when they start the concept work for the new car, we are right there in that process."

TRANSLOGIC 147: CES 2014 Autonomous Vehicles

We head back to CES in Las Vegas to check on the progress of autonomous vehicles in 2014. We go hands-free on the highway with Audi, narrowly avoid a collision with Ford and hear all about BMW's drifting driverless car. But first we take a ride on Induct's self-driving Navia shuttle.

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.
