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.

Ruminations in winter | 2016 Mazda MX-5 Miata long-term update

Winter is an odd time for our 2016 Mazda MX-5 Miata Club long-term tester. In the summer, the track beckons. Fall and spring bring top-down adventures at sunset. But our Miata is a little out of its enthusiast element when the weather is harsh and our moods grow as gray as a January day in Michigan. Sure, there's the occasional snowstorm, and equipped with winter tires the Miata can be a fun toy. But what about when it's just cold and dreary? We had a lot of time to reflect on our MX-5 these past few months, and we still managed to find enjoyment in the little things - even though admittedly this is not the time of year when the Miata shines. For starters, we taught associate video producer Amr Sayour how to drive a stick shift with the Miata. With its agreeable clutch and short throws, the six-speed manual was the perfect learning instrument for Sayour. His teacher, Adam Morath, actually had to show him how to stall. Arguably, learning to drive a manual isn't a little thing, but it was these run-of-the-mill events that showcased the Miata could be more than tolerable in winter. Associate Editor Joel Stocksdale used it for a 500-mile roundtrip to pick up a new pet and found it was a little tight for dog and driver. Though Stocksdale still enjoyed the sports-car feel, he came to the conclusion that "Miata is always the answer, but not always the best one." We also quickly realized the MX-5 isn't a great commuter car, nor did we expect it to be. It's low to the ground. It's loud. The small cabin has a greenhouse effect, and the windows fog easily. "If you have a Miata, it will creak and rattle in the winter. A lot. Nothing out of the ordinary here - this is a convertible with a lot of flexy parts - but something the casual shopper might not be aware of," Editor-in-Chief Mike Austin noted. Still, he found ways to have fun. "On the upside, winter tires = low-speed power oversteer." We had a lot of time to reflect on our MX-5 these past few months, and we still managed to find enjoyment in the little things. Speaking of those snowshoes, Stocksdale said they made our Mazda a "perfectly acceptable winter ride." Keeping the traction control on, he navigated his neighborhood roads in packed snow with little trouble. Like Austin advised, be aware of the ground clearance; Stocksdale got hung up in deep snow while attempting to scale his driveway.

Sweating the small stuff | 2017 Mazda CX-5 First Drive

The 2017 Mazda CX-5's door handles got their own design study. They got their own graphs, maths, and a team of people scientifically analyzing how humans interact with them. There was a whole to-do. And yet, you look at them back-to-back with their predecessors, a Spockian eyebrow reaching to the stars, and wonder what all the fuss was about. But apparently they're better. They're also perfectly illustrative of the entire effort to re-engineer and improve Mazda's best-selling model. At first, the 2017 Mazda CX-5 seems like a sensible evolution of its well-loved predecessor – there's sexier styling, a more premium cabin, and additional features, but the dimensions and engine specs look awfully similar. It certainly looks like one of those "the old car's great, let's not overthink the new one" redesigns. Except it isn't. Dig deeper and you'll see just how much meticulous work – from the door handles to the throttle response – went into making the new CX-5 a crossover that thoroughly trounces the majority of its competition. Take the efforts to make it quieter. According to Mazda's internal measurements, the sound-quelling improvements made for the CX-5's 2016 refresh already made it one of the quietest compact SUVs on the market. That apparently wasn't good enough. To what seems like an absurd degree, Mazda's engineers obsessively examined every nook, cranny, corner, and crevice to sniff out noise and eliminate it. Gaps were filled, insulation was injected, seals were added, air was redirected, glass was double glazed, and carpet replaced plastic coverings. It would seem that the Society of Persnickety Engineers is well represented at Mazda HQ. "I'm not sure how they found some of these," said Mazda vehicle development engineer Dave Coleman with a shake of his head, almost amused by the obsession and dedication of his colleagues across the proverbial hall in the sound-deadening department. (He goes over many of their enhancements in the video below.) And it worked. The new CX-5 is indeed incredibly quiet, even on San Diego's notoriously loud corrugated concrete freeways. It is quiet for a Mazda – a brand previously known for the exact opposite – and the entire segment. Even the fairly quiet 2017 Honda CR-V we drove on the same freeways on the way to San Diego couldn't match it. Actually, much of the driving experience can't be matched by a competitor.
