Here's how to follow this weekend's 24 Hours of Le Mans

In the pantheon of motorsports, the 24 Hours of Le Mans stands as one of the great endurance challenges to man and machine. This year's event in France already looks to be one for the ages with Porsche setting record-breaking times in practice and the competition debut of Nissan's front-engine, hybrid racer. Thankfully, there's a massive list of ways to follow this automotive attraction. Reilly Brennan, the Executive Director of the Revs Automotive Research Program at Stanford University, and a friend of Autoblog, has once again assembled a helpful couch-kit to organize many of the options. Unfortunately, the old-school way of just turning on the television might be the most frustrating way to watch Le Mans this year. Fox Sports 1 and 2 are carrying about half the race, but the coverage bounces between them seemingly at random. The broadcast begins on Fox Sports 2 at 8:30 AM Eastern ahead of the 9:00 AM start and lasts there until 12:00 PM. Things don't pick up again until 7:00 PM Eastern on Fox Sports 1 for an hour, and the channels swap back and forth more from there. The Fox Sports Go streaming app offers more, but even it stops showing the race a few times. Thankfully, streaming Le Mans is easy. If you can't dedicate 24-hours on the couch, Radio Le Mans lets you listen to audio commentary anywhere with some of the best announcers in the biz. The Automobile Club de l'Ouest, the governing body for the race, also offers an official video stream in an app for $9.99. For a really low-tech solution, the official Twitter is another choice. Brennan is keeping his list updated with coverage changes. You can also check out and download the spotter's guide (from Nissan) in the gallery above. Enjoy this year's race. If you miss anything, don't worry; expect a full report from Autoblog. In fact, editor-in-chief Mike Austin is attending Le Mans this year, so follow him on Twitter for on-the-fly impressions.

Audi planning A7 powered by fuel cell?

Back in March, Volkswagen AG CEO Martin Winterkorn voiced his doubts about the cost and infrastructure associated with building hydrogen fuel cell vehicles, but according to Autocar, that isn't stopping Audi from developing a fuel-cell version of the Audi A7. While we're inclined to take this report with a grain of salt, this wouldn't be the first time a VW executive has made seemingly damning statements about electric powertrains that later proved to be incorrect.
After speaking with Audi technical chief Wolfgang Dürheimer, Autocar reports that Audi is building a fuel cell A7 that is expected to be ready for testing by August. Like the electric E-Tron and natural-gas-powered G-Tron models, the hydrogen fuel cell Audis could, if produced, carry their own "tron" nomenclature.

Watch this Audi RS6 go 208 mph... on ice

In and effort to promote the high-speed grip of its new Hakkapeliitta 8 winter tire, Nokian threw a set of its new rubber on a race-prepped Audi RS6 and got moving - very, very quickly. In fact, on March 9 on top of the very frozen Gulf of Bothinia near Oulu, Finland, Nokian's test driver Janne Laitinen set a new world record for the fastest speed recorded driving on ice. If you'll recall, this isn't the first time that Audi and Nokian have played this game, either.
Using the guidelines set forth by the Guinness Book of World Records for such things, Laitinen averaged 208.602 miles per hour (335.713 kilometers per hour) over the course of two runs on natural, untreated ice. Another constraint is that the ice speed record must be done using commercial available tires, which is obviously great PR for the new Hakkapeliitas. The press release doesn't make any mention of how the RS6 was prepared to reach such high velocities, but the images of the car make it clear that this is no stock machine. Scroll on below to see the impressive video evidence of the Audi's record run.
