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and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation.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.

Evo blasts around in a Spa 24H-winning Mazda RX-7

Think of the Mazda RX-7 today, and your thoughts likely turn to the turbocharged third-generation version of the '90s that's an icon among the tuning and drifting communities. Many years before that swoopy coupe was hanging the tail out, the first model of RX-7 was also quite a track star, though. Evo's Richard Meaden has gotten ahold of a race-prepped version that counts a victory in the 1981 Spa 24 Hours to its name – the first Japanese car to claim that honor – for a fantastic video. With 225 horsepower and weighing around 1,984 pounds, this RX-7 doesn't look like a giant killer on paper. However as Meaden illustrates, the coupe puts those rotary-powered ponies to very good use. Driving it requires constantly keeping things on the boil because the muscle is essentially absent below 7,000 rpm. Once in the sweet spot, things start progressing quickly, though. As a wonderful cap to the wall of noise from the engine, little licks of flame also shoot out of the exhaust on downshifts. Thankfully, Evo's video team captures all of the mechanical noises quite well, and the clip is a treat for those with a good pair of headphones. Despite the race-winning pedigree, Meaden has no problem grabbing the little coupe by the scruff of the neck. He chucks it through the corners to get the tail loose, and the little wisps of smoke from the rear tires prove the original RX-7 knows how to drift too. These early cars definitely worth being remembered in the pantheon of Mazda performance.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
