Audi A5 and S5 freshen up for 2017

UPDATE: A previous version of this story mischaracterized the 2017 S5's engine configuration. The article has been updated. Well, here's the new Audi A5 and S5. They look a lot like the old ones, but just a tiny bit better. In other words, the redesigned coupes received the same treatment as their four-door counterparts, the A4 and S4. While the German press materials mention both gas and diesel engines, we expect the A5 to carry on in the US with petrol power only. Like the current A5, a 2.0-liter, turbocharged four-cylinder will serve as the base engine, but will probably get a similar power bump as the A4 – Audi hasn't released official figures yet. The four-door had its base output bumped from 220 horsepower and 258 pound-feet of torque to 252 hp and 273 lb-ft of torque. The S5 is a more interesting proposition than the S4. Where the old S5's 3.0-liter, supercharged V6 produced 333 hp and 325 lb-ft of torque, the new, turbocharged, 3.0-liter six-cylinder pumps out 354 ponies, according to the global press materials. That figure, fans of the old 4.2-liter V8-powered S5 will note, is identical to the original S5 that came out for model-year 2008. Torque figures aren't available yet, but we'd bet on at least a small increase in torque. Still, the increase in power is good for a 4.7-second run to 62 miles per hour, a 0.2-second improvement over the current car's 0-60 time. Audi claims it will offer the A5 with both six-speed manuals and seven-speed dual-clutch transmissions, but we wouldn't be so sure about that stick here in the US. The only available gearbox on the A4 is a seven-speed S-Tronic – coupes are inherently more sporting than sedans, but we aren't sure that's justification for Audi to offer a manual-trans A5 here in the US. Audi only mentions an eight-speed automatic for the S5. So no, the German press materials aren't a good indicator of the US-market A5. What we can rely on, of course, are the official images. The original A5/S5 was a handsome car, but Audi's designers have done a swell job styling the 2017 model. It looks good, and is somehow even more refined than last year's car. Audi's new corporate grille works well on a coupe body, although the powerful creases in the hood might be a little too powerful. The tail is lovely, like a prettier A3. The bodies are better looking, but they're also lighter and more aerodynamic, too. The A5's coefficient of drag is down to a slippery 0.25, while Audi's engineers lipo'd 132 pounds of fat.

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 Sport Quattro Concept speaks softly, carries a 700-hp stick

As promised, Audi has unveiled its Sport Quattro Concept here at the Frankfurt Motor Show, which takes inspiration from the 2010 Paris Motor Show debut known simply as the Quattro Concept. Both cars clearly seek to draw upon the company's legendary 1980 Ur-Quattro and its closely related Sport Quattro short-wheelbase rally special, yet this concept car looks more production-minded than the 2010 starlet.
Despite its more conservative duds, this handsome and muscular coupe actually packs significantly more power than the 2010 Paris showcar. In fact, it musters 700 horsepower and 590 pound-feet of torque from its plug-in hybrid powertrain, versus the Quattro Concept's more historically appropriate 2.5-liter five-cylinder turbo with 408 hp and 354 lb-ft. We're not going to complain about a twin-turbo 4.0-liter V8 plus an electric motor, nor will we grouse about its 3.7-second 0-62 mph dash, 190-mph top speed or 2.5 liters of fuel per 100 kilometers on the Euro cycle (roughly 94 miles per gallon US).
Stubborn rumors abound that Audi will offer a limited-edition version of this four-place coupe for sale, but for now, the company isn't talking. If such a model is offered, it's expected to cost significantly more than the R8 supercar, which might be a tough sell considering that vehicle's similar performance and more voluptuous - if less practical - shape.
