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 pushing DOT to allow its sequential LED turn signals [w/videos]

Still in the process of trying to get its trick LED Matrix Beam headlights legalized in the US, Audi is now trying to get its front and rear sequential LED turn signals approved by the National Highway Traffic Safety Administration. Just like its auto-dimming headlights, the sequentially illuminating turn signals don't meet NHTSA's Federal Motor Vehicle Safety Standard 108.
The problem, according to Automotive News, is that the individual lighting elements are too small to meet current US safety regulations. The rule states that each lamp should be 22 square centimeters (8.6 square inches) and the whole lighted combined area must be 50 square centimeters (19.6 square inches). In the individual sequence, Audi's lights are much smaller than that. As for the Ford Mustang, which has had sequential turn signals since 2010, this system is legal since the first lens is large enough to meet the required size, so the other two lights really aren't even necessary.
It sounds like it could be some time before we see these turn signals on Audis in the US, which is a shame because in addition to their styling bebefuts, we think they're more effective at signaling the vehicle's intended direction of travel, and they do a better job of grabbing the eye. Scroll down to watch a pair of videos showing the headlights in action on the redesigned A8/S8 as well as the recently updated R8.

VW recalling 2.64M vehicles worldwide over engine, light issues

Volkswagen is staging a massive, worldwide recall that's already grown from 1.68 million to 2.64 million vehicles and covers three different issues across a number of vehicles. We already reported on 61,000 Tiguans getting recalled over lighting issues - that was just in the US. Globally, however, VW will be recalling 800,000 Tiguans, according to Automotive News, with the focus on CUVs built between 2008 and 2011. The issue with the Tiguan relates to a simple fuse swap, so this is rather unremarkable, aside from the sheer number of vehicles being fixed. The real, troubling issues relate to gearboxes and pickups.
239,000 Amarok pickups (pictured right) are being recalled over fuel leaks, while 1.6 million vehicles are being recalled to swap the synthetic oil in dual-clutch transmissions with mineral oil. Now, the transmission issue is one for the global Volkswagen Group to address, not just the VW brand - vehicles from Audi, Škoda and Seat use the same seven-speed DSG and are covered under the recall, as well.
Why the switch from synthetic to mineral oil? Apparently, using the synthetic oil in a DSG and then subjecting it to stop-and-go conditions or heavy loads in a hot and humid climate can lead to electronic malfunctions, according to a Volkswagen press release. The switch, from the sounds of it, is largely a preventative measure.
