Felix Baumgartner parachutes into racing at N?rburgring 24

There are plenty of commonalities to be found between astronauts and racing drivers. Both are daredevils by definition (if not by trade), both subject themselves to unfathomable G forces and both face very real risks when strapped into machinery that makes the very best use of advanced propulsion, aerodynamics and composite construction technologies. Yet you don't find much crossover between the two. There was talk of Niki Lauda, himself an experienced pilot, training to go into space with Virgin Galactic (which itself was sister to an F1 team for a while in Richard Branson's empire), but that didn't seem to materialize. Now we're receiving news that Felix Baumgartner will contest the Nürburgring 24 Hours this year.
Felix Whomgartner, you ask? Felix Baumgartner. He's more of a skydiver than an astronaut, but he made history in 2012 when he jumped out of a space capsule and set the record for the highest altitude in a manned balloon, the parachute jump from the highest altitude, and the highest velocity freefall as part of the Red Bull Stratos initiative. In other words, he may as well be an astronaut, because he fell down to the earth's surface from the stratosphere.
For his next challenge, Baumgartner will be climbing into an Audi R8 LMS Ultra in an attempt to tackle the Nürburgring. Having contested a handful of spec races under the VW Group umbrella, he'll undertake several test sessions and practice races before the main event in June, in which he'll alternate behind the wheel with professional racing drivers Frank Biela, Marco Werner and Pierre Kaffer. The initiative is part of the Audi race experience program that allows gentleman racers to team up with seasoned pros to take part in real races. Baumgartner will undoubtedly prove its highest-profile participant.

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.

Audi TT Offroad concept packs 408 hybrid horsepower, yet returns 123 mpg

Audi took the wraps of its TT Offroad Concept at the Beijing Motor Show, after teasing us with sketches earlier this month. "The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family," says Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development. "It combines the sporty genes of the TT with the strengths of a compact Audi SUV."
The latest in Audi's eTron show cars reminds us an awful lot of the the Audi Allroad Shooting Brake concept that debuted a few months ago at the Detroit Auto Show. In addition to very similar physical appearances, the two share the same plug-in hybrid propulsion systems (the "plug-in" part is a bit misleading, as the concept simply needs to be parked over an inductive pad to take advantage of Audi Wireless Charging technology).
Proving that hybrid power never has to be a compromise, the TT Offroad Concept packs a 292 horsepower turbocharged 2.0-liter four-cylinder under the hood. The combustion engine is assisted by two electric motors (rated at 40 kW at the front and 85 kW at the rear) to provide a total system output of 408 horsepower and nearly 480 pound-feet of torque. With all-wheel drive, the concept hits 60 mph in 5.2 seconds and tops out at 155 mph - while returning a provisional fuel efficiency of 123 miles per gallon equivalent.
