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 to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

Audi reveals Prologue Allroad concept ahead of Shanghai

Audi kicked off the Prologue series of design studies with the coupe concept unveiled in LA, then followed up with the Prologue Avant wagon at the Geneva show. Now, we're seeing the third iteration in the form of the Prologue Allroad concept. Set to be unveiled next week at the 2015 Shanghai Motor Show, the Prologue Allroad picks up where the previous two left off, but takes it in a more rugged direction. At 16.8 feet, it's longer than both of the previous concepts, and stretches out to the same length as a standard-wheelbase A8. It also rides three inches higher than the Prologue Avant concept. Not only is it larger than the preceding showcars, it's also more powerful. Under the hood sits a hybrid powertrain that pairs a 4.0-liter twin-turbo V8 to an electric motor integrated into eight-speed automatic transmission. Together they produce a whopping 738 horsepower and 664 pound-feet of torque, driven to all four wheels to send the concept to 62 miles per hour in a scant 3.5 seconds – all the while returning a claimed equivalent of 98 miles per gallon. If that's not the best of both worlds, we don't know what is. Plus, the car packs an inductive charging system that Audi says it's developing for production. Massive 20-inch brake discs keep that performance in check, sitting inside 22-inch wheels, all mounted to an adaptive air suspension and four-wheel adaptive steering. Other exterior features include door lock sensors integrated into the window frame, Matrix laser headlights and LED taillights. Inside it's all angular yet elegant, swathed in dark blue, beige and brown. Display screens abound, stretching across the dashboard with a deployable OLED infotainment display in the center console. There's another OLED screen for the passengers in the pair of rear seats, who can also dock OLED tablets in the front seatbacks. A pop-up "sound spoiler" promises to envelop the cabin in music, and there's inductive charging for mobile devices as well. Together with its conceptual stablemates, the Prologue Allroad concept points towards a stylish and technologically advanced future for Ingolstadt, and we're looking forward to seeing this show car transition into production as the next A6 Allroad. In the meantime, you can scope out all the details in the press release below and view the concept from every angle, inside and out, in the slideshow above.
