Next Audi A7 redesign will include more traditional rear end

A report in Automobile says that Audi is rethinking the design of the next A7. Audi told Car and Driver that owners "have trouble with the radical tail of the A7," so its model-defining rear end will give way to something more traditional. Automobile is light on specifics of the redesign, but the general direction is "a lower, wider, and more expressive shape." The philosophy behind the dimensions and styling is a "C/D shift," meaning Audi wants to give its C-segment hatchback the bearing, gravitas, and visual delight of a D-segment vehicle. That would help the A7 stand out from its in-house competition, and could make for higher transaction prices. Having heard about different design directions from Audi for years without much in the showroom to back it up, we could define what we'd love to see in two words: more Prologue. This is Audi, so you know the next A7 will be packed with tech. We expect an emphasis on touchscreen interfaces, a digital dash cluster a la the TT that moves with the steering column, a HUD with night vision, and an MMI system a few more steps down the evolutionary trail. Engines will see some upgrades like the addition of a plug-in hybrid, the excellent 2.0-liter, turbocharged four-cylinder getting a 74-horsepower e-boost assist to 326 horsepower, the 3.0-liter V6 slated for the S7 rising to 500 hp, and the 4.0-liter V8 in the RS7 pumping out 575 hp.

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 Q8 E-Tron could have 370-mile range

Audi technical boss Ulrich Hackenberg has a huge job ahead of him if he's going to add more electrified models his employer's portfolio. Currently, the German company's electrified offerings amount to just the Q5 Hybrid in the US and the A3 E-Tron in Europe, but British auto mag Autocar is claiming that Hackenberg wants to add a Tesla Model X-rivaling electric version of the company's long-rumored Q8 utility vehicle to the plans. That E-Tron model, said to be a high-riding crossover with coupe-like lines, is expected to be Ingolstadt's CUV flagship, positioned just above the Q7 (pictured above).
Autocar further maintains that Q8 E-Tron will borrow its front- and rear-mounted electric motors (good for around 375 horsepower) from the recently revived R8 E-Tron, and the model could be ready as soon as 2017. This sporty CUV is expected to have a much greater range than the two-door electric sports car, however. Figure on about 370 miles thanks to room for extra batteries.
The still-not-confirmed Q8 range is expected to be offered with gasoline, diesel and plug-in hybrid powertrains, and will ride on the same platform as the Q7, albeit fitted with sleeker styling. Like all of Audi's upper-end offerings, it will make extensive use of aluminum for the body and chassis to keep weight down.
