Audi prices 2014 A8L TDI from $82,500*

During the Los Angeles Auto Show last November, Audi told us that it would be bringing four new diesel-powered models to the United States this year. The first to arrive is the 2014 A8L TDI you see here, and we've now learned that the big oil-sipper will be priced from $82,500, (*excluding $895 for destination).
The whole new range of diesel models will be powered by Audi's 3.0-liter TDI V6, good for 240 horsepower and 406 pound-feet of torque in this application. Of course, Quattro all-wheel drive is standard, and even in the big A8, the diesel grunt will be enough to propel the long-wheelbase flagship to 60 miles per hour in 6.4 seconds (almost a full second slower than the A8 3.0T we reviewed last fall). That said, the A8 TDI should still be a pretty engaging steer, and considering the fact that this thing will reportedly return fuel economy figures of up to 36 miles per gallon on the highway (24 in the city), a slightly slower launch time is well worth it. (The A8 3.0T tops out at 28 mpg highway.)
Elsewhere in the segment, Mercedes-Benz offers a diesel version of its S-Class flagship, retailing for $93,000 and good for fuel economy figures of 21/31 mpg city/highway. By comparison, the A8 TDI seems like a steal, and we'll be interested to see where the forthcoming BMW 7 Series diesel falls into the class of huge oil-burning barges.

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.

2016 Audi S6 Quick Spin [w/video]

Back in my salad days, when I was rocking a the greatest Civic Si of all time, the occasional pair of leather pants, and a yen for malt liquor and grass (both of which quickly put an end to the leather pants), a car like the 2016 Audi S6 would've made my head explode. "What's that?" I might have asked. "A roomy four-seat Audi with more than 400 horsepower and all-wheel drive, that looks like it was sculpted by Ralph McQuarrie? Pushing 30 mpg and under five seconds to 60 miles per hour? The hell you say." And that's even before Future Me showed Skinny Me an interior full of carbon fiber and aluminum, God's own quilted-leather sport buckets, and a 'radio' that would've made my Dreamcast look like an Atari 6400. (If you haven't picked up on the vibe yet, I was kind of a weird nerd in the late '90s.) Gentlemen, we live in the future; I just drove a mid-cycle-refresh Audi that proves it. Driving Notes The 4.0-liter, turbocharged V8 is tailor-made for smoothly pulling around anything less-well-endowed than the M5/E63/CTS-V set. Now up to 450 horsepower and 406 pound-feet of torque (versus the 420 hp and 406 lb-ft of last year's model), there's enough pull in the easily accessible powerband to satisfy all but lunatic drivers. It doesn't feel staggeringly fast, but that's only because 500 horsepower has become so commonplace in the new uber sedan game. It's quick enough. Remember when 250 hp was a crazy number? The car sounds like it has a V8, too. That may seem obvious, but in Generation Direct Injection things tend to get a bit clattery. You'll get some of that if you open the hood with the engine running (as I did in one of the Short Cuts above), but none where it counts: behind the wheel, windows up, stereo down, foot to the floor. That recipe delivers a hushed, baritone-sung song about understatement. Less subtle is the braking force when used at or near the top of its ability. After a moment of surprise and delight while decelerating in normal traffic, I went back-road hunting to test a few pseudo panic stops. Vented 15.7-inch front discs, with 14-inchers in the rear, provided a fast and steady haul-down from 70 miles per hour. Remember when wheels were 15 inches? I mean, you need those big brakes and potent engines to move and stop a car this hefty. With a base weight of 4,486 pounds – no doubt heavier still in my loaded, Dutchman-driven example – it still kind of blows my mind to see the 27-miles-per-gallon highway number.
