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.

2015 Audi TT's digital gauge cluster to spread throughout lineup

File this one under: "makes sense to us." According to Car and Driver, the slick new gauge cluster found in the 2015 Audi TT will expand to other models in the automaker's lineup. In the near term, expect the tech to make its way into the next R8 supercar (with a special performance display for that model), as well as the upcoming, all-new versions of the A4 sedan and Q7 crossover.
Audi's new customizable gauges first debuted at this year's CES - it uses a 12.3-inch TFT display, and, while similar to the systems found in the Cadillac CTS, XTS and Mercedes-Benz S-Class, this system has the ability to show full-screen, three-dimensional maps. We had a chance to check out the new display in-person at CES, and found it to be impressive, though we're curious to see how distracting it is while driving.
Car and Driver says the system is still undergoing small tweaks before Audi officially launches it in the TT later this year. From there, the display will be standard in the R8, but Audi is unsure about whether or not to offer it as a standalone option in the higher-volume A4 and Q7 models.

Autoblog gets ready for Le Mans with an R8 road trip and Allan McNish

This car is the master link between what Audi does on the race track and sells on the road.
We're attending the 24 Hours of Le Mans with Audi and we figured we'd make the world's biggest endurance race even more interesting by driving from Munich to Le Mans in an R8. We've also had a brief chat with Audi driver Allan McNish, and if you haven't already, check out all the multimedia ways to enjoy the next four days from the Circuit de la Sarthe, then read on.
