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.

Mazda 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

Watch this 1,500-hp Mazda MX-5 smoke a race track

In December 2014 we watched New Zealand drifter "Mad Mike" Whiddett assemble his RADBUL, an NC-series Mazda MX-5 Miata with a four-rotor engine aided by twin Garrett turbochargers. The Dr. Frankensteins at engine builders Pulse Performance expected their creation to be good for 1,500 horsepower. This year we get to watch Whiddett run the monster around Highlands Motorsports Park in New Zealand, brewing up enough tire smoke to set of fire alarms in the International Space Station. When the car was finished in February Pulse Performance put it on the dyno, toning down the boost because "the tires easily smoked the rollers." The result on the day was 1,032 horsepower from the 2.6-liter engine. When Whiddett campaigned it at the Forth Worth, TX round of this year's Formula Drift Pro Championship, he said tiny adjustments have a huge effect on the way the car behaves so they were still trying to find the right balance a few months into the season because of the testing limit outside of competition. Unsurprisingly, he also said the car "is so damn fast that I'm actually having trouble slowing down." RADBUL is the third in Whiddett's line of Mazda drift specials, after the RX-8 BADBUL and the RX-7 MADBUL.
