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.

Audi highlights headlights on upcoming new R8

Audi is preparing to roll out an all-new R8... but it's not about to reveal the whole thing at once. So in the first in what promises to be a series of teasers, the German automaker is showing off the new supercar's headlights. (Or headlight, we should say, in the singular.) Not unlike the R8 LMX revealed in Paris, the second-generation Audi supercar will incorporate LED headlights with an optional laser high-beam module. Unfortunately since laser headlights are illegal in the United States, the option isn't likely to be offered here. That is, at least, until Audi succeeds in convincing federal regulators otherwise. Although the teaser image above, like the press release below, may shine the light (so to speak) principally on the headlights, the shrouded shape also gives us a (little) bit to chew on. Yes, it will be available in blue, but beyond that we can expect the new R8 to incorporate slightly more angular lines than the model it replaces, with a more pronounced trapezoidal grille up in an overall design similar to the new TT, only more so. But then we already knew that much and more from the undisguised image that leaked out a little over a week ago. Ingolstadt, 2015-02-16 Audi reveals laser headlights for the new R8 - New mid-engine sports car features high-tech headlights - Laser high-beam offers high light intensity and excellent range Audi is revealing the headlights of its new R8* as the first of a number of technology highlights of the top sports car. The R8 uses LED headlights which can be supplemented by a laser high beam lighting module as an option. The new R8 will set new standards among high-performance sports cars – including in its lighting technology. As an option, the latest car development by Audi can be equipped with a laser spot as the high-beam headlight. The special appeal of laser lighting is that it uses high-intensity laser diodes, which generate a lot of light energy from a very small component. Compared to LED high-beam headlights, laser high-beams attain nearly twice the lighting range. Each headlight contains one laser module that operates with four high-intensity laser diodes. This module bundles the four intense blue-light laser beams. Then a phosphor converter transforms the blue light into pure white light. An identifying characteristic of the laser headlights is their blue light signature. Standard equipment in the new R8 includes an LED headlight system.

Audi celebrates 25 years of TDI

Nope, the diesel engine never really did go out of style for Audi. Now, the German automaker has released a video reminding the world of its persistence with the oil-burners and is commemorating the Silver Anniversary of Audi's first commitment to turbodiesels in 1989. And, yes, there are some road racers shown in the clip, so some of those bad boys actually move pretty well. Audi engineers on camera admitted to some of the early TDI engines being "slow" but still valuable for their torque and, obviously, their fuel economy relative to gas-powered engines. A bunch of tinkering later, though, and Audi says its diesels can be a legitimate "part of a performance car" and has even overcome the issue of noisiness that's often associated with diesels. The automaker made some news in these parts a few years back when its Audi A3 TDI won the 2010 Green Car of the Year at the annual LA Auto Show in late 2009, and the model even succeeded a fellow diesel (the Volkswagen Jetta TDI) to boot. Granted, diesel sales aren't nearly as popular in the US as they are in Europe. Still, Audi last year boosted its diesel sales in the US by 40 percent to 10,076, which was about a tenth of what sister company Volkswagen sold in diesels last year in the States. And things have looked even rosier this year for Audi's TDI sales. Through June, Audi diesel sales have almost quadrupled from a year earlier to more than 8,100 units.
