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.

2016 Mazda CX-3 scores 29/35 mpg EPA ratings

Looking for a subcompact crossover that won't cost you too much at the pumps? Your best bet is now the new Mazda CX-3, according to fuel economy figures released by the EPA. Mazda's new baby crossover has been rated by the US government agency at 29 miles per gallon in the city, 35 on the highway, and 31 on the combined cycle. That's in front-drive spec, giving the CX-3 better fuel economy than anything else in its class (at least, that is, with an automatic transmission.) Option it with all-wheel drive and you'll take a slight penalty at 27 mpg in the city, 32 on the highway, and 29 combined. According to Mazda that still "makes it among the most fuel-efficient all-wheel-drive vehicles available in the US." Whichever drivetrain option you go for, the CX-3 packs a 2.0-liter inline-four with direct injection (Skyactiv-G in Mazda-speak) good for 146 horsepower and just as much torque, mated to a six-speed automatic transmission. The first examples will begin reaching American showrooms later this summer.

As Mazda's first foray into the quickly burgeoning subcompact crossover class of vehicles, CX-3 provides those seeking a purposeful, stylish and sporty vehicle option that bucks convention. CX-3 offers standard keyless ignition and backup camera, and is available with features that are unrivalled in its class like Mazda Radar Cruise Control, adaptive LED headlights and Mazda's signature driving experience. Front-wheel-drive models have EPA-estimated fuel economy of 29 mpg city/35 mpg highway/31 mpg combined, while models equipped with Mazda's predictive i-ACTIV AWD have EPA-estimated fuel economy of 27 mpg city/32 mpg highway/29 mpg combined. That makes it among the most-efficient all-wheel-drive vehicles available in the U.S. "SKYACTIV Technology means we don't have to compromise when it comes to performance, efficiency and fun-to-drive dynamics," said Jim O'Sullivan, president and CEO, Mazda North American Operations.

Mazda won't build new Mazdaspeed3 or 6 based on current models

It's sad news but not entirely unexpected: According to a Motoring interview, Mazda doesn't intend to build high-performance versions of the latest Mazda3 and Mazda6. Instead, it will wait for the next generations of those cars to arrive before applying the Mazdaspeed treatment. When the future performance models do eventually arrive, expect them to take a step upmarket compared to the last ones. In the meantime, the Japanese brand will focus its engineering resources on the next-generation Skyactiv engine family, according to Mazda's North American operations president and CEO Masahiro Moro. "Our research and development department is 100 percent focused on delivering Skyactiv generation two and if we don't have this we don't have any other derivatives," Moro told Motoring. Once the new engines arrive around 2017, Mazda's engineers can start to develop performance versions. "MPS or performance model or a sort of iconic model of the future will be a little bit later at this stage," Moro said. Moro is already thinking about the direction for the future performance vehicles. He calls the previous Mazdaspeed3 "childish" and thinks it's time to go a different way. "Mazda brand has become more mature, more upscale, more sophisticated, and we have a new transition of the brand to relate that direction," he said. Rumors last year suggested that Mazda might introduce a new Mazdaspeed3 (speculative rendering above) as a concept at the 2015 Frankfurt Motor Show. It would have reportedly used the CX-9's 2.5-liter turbocharged four-cylinder tuned to 295 horsepower and an all-wheel-drive powertrain. The vehicle never appeared, though. The current Mazda3 and Mazda6 arrived in 2014, so a new generation of each wouldn't arrive until around 2020. That would put Mazdaspeed derivatives at 2021 or later. In short, it will be a while. For customers that have the Driving Matters attitude now, Mazda still offers the award-winning MX-5 Miata as a convertible and soon with an impressive folding hardtop. Plus, Fiat will sell its own versions of the car with 160 hp. We wouldn't mind if Mazda turned up the heat a little by introducing something like the Racing concept from last year's Tokyo Auto Salon, though. Related Video:
