Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

Audi re-illuminates Sport Quattro with Laserlight concept for CES

Automakers typically spend months working on a concept car, then unveil it at a car show and move on to the next. But Audi has demonstrated a propensity at refining the same concepts and bringing them back for more. Just look at how many time Audi iterated its E-Tron concept, and how many diesel R8s it toyed with. It brought the Italdesign Parcour out of retirement and rechristened it the Audi Nanuk, and it's been doing the same with the Quattro concept for the past several years. The German automaker rolled out the first Quattro concept back in 2010, and followed up with the reborn Sport Quattro concept less than a year ago. And now it's preparing to unveil yet another.
Called the Sport Quattro Laserlight concept, this time it's not as radical a departure from the Sport Quattro concept as that was from the first Quattro concept. In fact, there's really only one vital difference. That'd be the laser headlights "that leave all previous systems in the dark," according to the press release below. The system uses matrix LEDs around the outside of the element as low beams, and lasers on the inside for high beams. Measured in mere microns, the laser diodes are significantly smaller than LEDs, while lighting up the road ahead for nearly half a kilometers (1,640 feet), providing twice the lighting range and three times the brightness of LED high beams.
Otherwise the concept car you see here and which Audi will display at the Consumer Electronics Show in Las Vegas next week is essentially the same as the one it showed in Frankfurt this past September. It's got the same measurements, wearing the same CFRP bodywork, with the same interior and the same 700-horsepower hybrid powertrain, only the yellow exterior has been repainted Plasma Red and the black interior redone in a more low-key Slate Grey, as you can see from the high-res image gallery above.

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.
