2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.

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.

Audi re-illuminates Sport Quattro with Laserlight concept for CES

Automakers typically spend months working on a concept car, then unveil it at a car show and move on to the next. But Audi has demonstrated a propensity at refining the same concepts and bringing them back for more. Just look at how many time Audi iterated its E-Tron concept, and how many diesel R8s it toyed with. It brought the Italdesign Parcour out of retirement and rechristened it the Audi Nanuk, and it's been doing the same with the Quattro concept for the past several years. The German automaker rolled out the first Quattro concept back in 2010, and followed up with the reborn Sport Quattro concept less than a year ago. And now it's preparing to unveil yet another.
Called the Sport Quattro Laserlight concept, this time it's not as radical a departure from the Sport Quattro concept as that was from the first Quattro concept. In fact, there's really only one vital difference. That'd be the laser headlights "that leave all previous systems in the dark," according to the press release below. The system uses matrix LEDs around the outside of the element as low beams, and lasers on the inside for high beams. Measured in mere microns, the laser diodes are significantly smaller than LEDs, while lighting up the road ahead for nearly half a kilometers (1,640 feet), providing twice the lighting range and three times the brightness of LED high beams.
Otherwise the concept car you see here and which Audi will display at the Consumer Electronics Show in Las Vegas next week is essentially the same as the one it showed in Frankfurt this past September. It's got the same measurements, wearing the same CFRP bodywork, with the same interior and the same 700-horsepower hybrid powertrain, only the yellow exterior has been repainted Plasma Red and the black interior redone in a more low-key Slate Grey, as you can see from the high-res image gallery above.
