2015 Audi A6 spiffs up for Paris Motor Show duty

While the big names at the Audi booth might be dominated by the TT line, it's not the only product getting some attention from the German company. The A6, on sale in its present form since 2012, is getting its official mid-cycle refresh.
Featuring light exterior freshening, the new fascia wears a tweaked grille and slimmer, more expressive headlights. The rear end sees more substantial changes, with a freshened rear bumper that features rectangular exhaust outlets and more dramatically redone taillights.
Under hood, the 3.0-liter, supercharged V6 engine now produces 329 horsepower, while the 3.0-liter, turbodiesel V6s are available in 215- or 268-hp varieties, or in twin-turbocharged form, with 315 hp or 322 hp. The other big powertrain news surrounds the transmission. Audi has finally dropped the continuously variable transmission from the base, front-drive A6, slotting in a dual-clutch transmission in its place.

The skinny on Delphi's autonomous road trip across the United States [w/videos]

Rolling out of an S-shaped curve along Interstate 95, just past Philadelphia International Airport, the final obstacle between the autonomous car and its place in history appeared on the horizon. So far, the ordinary-looking SUV had traversed the United States without incident. It had gone through tunnels and under overpasses. It circled roundabouts and stopped for traffic lights. Now, on the last day of a scheduled nine-day journey, it was poised to become the first autonomous car ever to complete a coast-to-coast road trip. First, it needed to contend with the Girard Point Bridge. Riding in a rear seat, "I saw that bridge coming, and I thought, 'Oh my gosh, this is going to be a grab-the-wheel moment," said Kathy Winter, vice president of software at Delphi Automotive. The car, an unassuming Audi SQ5 nicknamed Roadrunner, had been well-tested. Back in January, a few inebriated pedestrians fell flat in front of the car during a demonstration in Las Vegas. It was the quintessential worst-case scenario, and the car admirably hit the brakes. More than drunken louts, bridges present a sophisticated challenge for the six radar sensors that feed data to the car's internal processors. Instead of sensing solid objects, radar sensors can read the alternating bursts of steel beams and empty space as conflicting information. "They're a radar engineer's worst nightmare," said Jeff Owens, Delphi's chief technology officer. Girard Point Bridge, a blue skeleton of girded steel that spans the Schuylkill River, might be a bigger challenge than most. Traveling across the lower level of its double decks, the autonomous car's radar sensors had to discern between two full sets of trusses. Cross the Schuylkill, and Delphi's engineers felt confident they'd reach their destination: the New York Auto Show. For now, the sternest test of the trip lay directly in front of them. A Data-Mining Adventure Until that point, the toughest part of the journey had been finding an open gas station in El Paso, TX. Trust in the technology had already been established. The main reason Delphi set out on the cross-country venture with a team of six certified drivers and two support vehicles was to capture reams of data. What better way to do that than dusting off the classic American road trip and dragging it into the 21st century? They did exactly that, capturing three terabytes worth of data across 3,400 miles and 15 states.

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.
