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.

2017 Mazda MX-5 Miata RF Quick Spin | Elevate yourself

It's unusually hot in Western Washington; the early August sun beams through skies rendered hazy by fires a few hundred miles to the north. If you're not moving, it gets a bit oppressive, since there's just enough humidity to feel it and not enough wind to relieve it. Instead of huddling inside, window shades drawn, fan blowing hot air around impotently – this is how most Washingtonians, 75 percent of whom don't have A/C, handle the heat – we're taking our fan on the road. The best way to beat the heat, it turns out, is to climb into the forests. For this adventure in body temperature regulation, we've got a Mazda MX-5 RF, the Miata's semi-targa-topped variant, and a few hours of time. And the Cascade Mountain's foothills, thickly coated with Douglas firs and, higher up, subalpine firs soaking up as much sun as they can in the short growing season. I've lived near the foothills nearly all my life, but there's a lot of the Cascades I haven't explored. One area is Chinook Pass, a mountain road that crests at 5,430 feet. Looming almost 9,000 feet above it is Mount Rainier, so close you can almost touch it. Just about 100 feet below the summit is Tipsoo Lake, startlingly clear and sporting enough wildflowers to make The Sound of Music look like a movie about Rommel's North Africa campaign. But that's jumping ahead a bit. Between me and the summit is about 90 minutes of driving, through the suburbs and into the Enumclaw Plateau, and then along the chalky White River and up into the mountains. Plenty of time to focus on nothing but the surroundings, and the quality of the cooling action provided by the little Mazda. A quick word about the car, and my own biases – I love Miatas, but I have a complicated relationship with the latest MX-5, having owned a much more visceral (and much slower) first-gen car for about six years. On paper, it's this perfect modern interpretation of the original. It's light, it's a momentum machine, the steering's just a tad overboosted, and it has a playful amount of body roll while maintaining a healthy amount of mechanical grip. It looks aggressive enough, too, a major complaint of many folks about the last-gen car's Joker smile. The interior is largely brilliant, amazingly simple and interesting for such a lithe car. And yet, I have never found the new car to be as charismatic as my old Miata, with all its flaws. This puts me in the minority; most MX-5 fanatics find the ND to be a great compromise.

Toyota Yaris iA, Mazda CX-3 sales show crossover formula isn't an automatic win

While 2017 was another watershed year for crossovers, in one interesting case, a crossover had its lunch eaten by its sedan counterpart. In the past year, Toyota sold nearly 36,000 Yaris iAs, a sedan that is identical to the foreign-market Mazda2 in everything but Toyota's ugly front bumper. In the same time frame, Mazda sold just over 16,000 CX-3s, a subcompact crossover based on the Mazda2. Not only that, but the Yaris iA saw an increase of around 8,000 units over 2016, and the CX-3 sold about 2,000 fewer units than in 2016. View 29 Photos There are a few reasons this is surprising. First of course is that the crossover market is surface-of-the-sun hot right now, so much so that primarily crossover-building brand Subaru saw its best sales year ever last year. Even Mazda's other crossovers, the CX-5 and CX-9 saw better sales in 2017 than in 2016. But on paper, the CX-3 has a number of advantages compared to the Yaris iA. The CX-3 has a larger 2.0-liter four-cylinder that makes about 40 more horsepower than the 1.5-liter engine in the Toyota. Also, while the cargo area behind the rear seats in the CX-3 is about one cubic foot smaller than the iA, it has the added flexibility of being a hatchback, and thus having more capability when it comes to large, bulky items. And of course, the CX-3 is quite a shapely machine compared with the awkward, angry-looking iA. That's not to say the iA doesn't have any of its own advantages. It gets 3 more mpg in the city and 6 more on the highway than the CX-3. It also costs roughly $3,000 to $4,000 less than a CX-3 and can be found at more dealers than the Mazda. But it's still surprising that a car, especially a sedan, can outsell a mechanically very similar crossover. Apparently the formula of adding more ground clearance and plastic fenders isn't foolproof. Then again, maybe it's not such a big deal to Mazda, since the CX-3's total sales were just over a tenth that of the Mazda CX-5. Related Video:
