Audi S3 Sedan boasts SAE 296 hp, 0-60 in 4.7 seconds

The (technically speaking) 2015 Audi S3 sedan should start at right near $39,000.
The last time Audi gifted the world with a small sport sedan was way back when the A4 wasn't an entry-luxury executive car costing relative gads of dough, so maybe since the mid-1990s. In a company decision reversal, we're now officially getting the new A3 Sportback starting later this year, but that's a five-door hatch and not a big volume attraction for markets like the United States. And there's no guarantee we'll get the S3 Sportback version yet. So, what to do?

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.

2015 Audi RS7 Dynamic Edition is a pretty car for a pretty penny

Making its world debut at the New York Auto Show, and commanding a $40,250 premium over the base RS7, is Audi's new 2015 RS7 Dynamic Edition that arrives with an MSRP of $146,045 (including destination and delivery). The range-topping hatchback is designed to showcase Audi's exclusive program, which allows customers to choose choose from the automaker's long list of options and then take the customization one step further with bespoke paintwork, upholstery, bodywork and wheels.
The interior features Black Valcona leather seats with Crimson Red honeycomb stitching, and matching Crimson Red seat belts. The contrasting color is carried through to the stitching on the dashboard, center armrest, door panels, shift boot and center console. Carbon fiber inlays provide additional contrast. The exterior is offering in four colors (Ibis White, Suzuka Gray metallic, Daytona Gray pearl and Phantom Black pearl), with each arriving with performance-oriented DRC suspension (with three-stage adjustable dampers), 21-inch Gloss Black wheels, Tornado Red painted brake calipers and sport exhaust. A carbon fiber front splitter, rear diffuser and carbon fiber engine cover complete the package.
Like the standard RS7, the Dynamic Edition arrives with a twin-turbocharged 4.0-liter V8 rated at 560 horsepower and 516 pound-feet of torque. With an eight-speed automatic transmission, running through Audi's Quattro permanent all-wheel drive and a sport differential, the four-passenger vehicle will crack the 60 mph acceleration benchmark in a reported 3.7 seconds - and, thanks to cylinder-on-demand technology, it avoids a gas-guzzler tax. The RS7 Dynamic Edition arrives at dealerships in early summer.
