Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

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.

Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:
