Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

Audi prices 2014 A8L TDI from $82,500*

During the Los Angeles Auto Show last November, Audi told us that it would be bringing four new diesel-powered models to the United States this year. The first to arrive is the 2014 A8L TDI you see here, and we've now learned that the big oil-sipper will be priced from $82,500, (*excluding $895 for destination).
The whole new range of diesel models will be powered by Audi's 3.0-liter TDI V6, good for 240 horsepower and 406 pound-feet of torque in this application. Of course, Quattro all-wheel drive is standard, and even in the big A8, the diesel grunt will be enough to propel the long-wheelbase flagship to 60 miles per hour in 6.4 seconds (almost a full second slower than the A8 3.0T we reviewed last fall). That said, the A8 TDI should still be a pretty engaging steer, and considering the fact that this thing will reportedly return fuel economy figures of up to 36 miles per gallon on the highway (24 in the city), a slightly slower launch time is well worth it. (The A8 3.0T tops out at 28 mpg highway.)
Elsewhere in the segment, Mercedes-Benz offers a diesel version of its S-Class flagship, retailing for $93,000 and good for fuel economy figures of 21/31 mpg city/highway. By comparison, the A8 TDI seems like a steal, and we'll be interested to see where the forthcoming BMW 7 Series diesel falls into the class of huge oil-burning barges.

Audi RS6 Avant and Mercedes-AMG E63 S drag race for Top Gear

Sometimes the kids are late for school, and you need a wagon to get them there in a hurry. In its latest drag race, Top Gear finds out which is the quicker high-performance family hauler: the Audi RS6 Avant or the Mercedes-AMG E63 S. The specs suggest this race should be quite close at the finish line. The RS6 has a 4.0-liter twin-turbo V8 with 552 horsepower, but the E63 S is a little more powerful with 577 hp from a 5.5-liter twin-turbo V8. However, the Audi has a traction advantage from the all-wheel drive system, whereas the Mercedes only spins its rear wheels. Pick your favorite, and then watch the video to see if the similar numbers translate to a photo finish in the real world. Related Video:
