Overnight action from the 24 Hours of Le Mans

We won't go into a recap here, but there are still leading positions being fought for in all classes - it's so close that leads are changing when a car goes into the pits. We'll let the recap wait until the end of the race, so for now enjoy some shots from last night's action at the 24 Hours of Le Mans.

2014 Audi RS7 priced from $104,900* in the US [w/video]

Audi has officially priced the svelte 2014 RS7 from $104,900 (*not including $825 for destination), undercutting its sole competitor, the BMW M6 Gran Coupe, by $8100. Even when we're talking about six-figure super sedans, that's not a small amount of money. And soon, this class of sleek stormers will be joined by the updated Mercedes-Benz CLS63 AMG 4Matic.
With its combination of a twin-turbocharged, 4.0-liter, 560-horsepower V8 engine and Audi's excellent Quattro all-wheel drive, the RS7 is expected to hit 60 miles per hour in just 3.7 seconds, 0.4 seconds faster than the manufacturer estimate for the M6 Gran Coupe.
We've already given the RS7 a thorough shakedown in Europe, and we came away quite impressed with just how stunning this Audi is, both to drive and to look at. Now that we've got a price to go along with the performance and style, this Audi is even more appealing - in our high-dollar dreams, anyway. Take a look at a short video from Audi, as well as the official press blast, below.

2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.
