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 hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

'Gran Turismo Sport' Super Bundle comes with a real Mazda Miata

"Gran Turismo Sport" is now on sale (stay tuned for a full review in the near future), and as with most video games now, there are basic versions and those that come with a few extras. For instance, in the United States there's a Limited Edition version that includes the full game, plus a metal box, several Group B rally cars and a couple of prototype cars unlocked, as well as 1,000,000 credits available at the start. It's a pretty meager special edition compared with the "Gran Turismo Sport" Super Bundle on offer in Taiwan, though. The Super Bundle lives up to its name primarily because it comes with a real, drivable Mazda MX-5 Miata. It comes in Soul Red and features custom Gran Turismo vinyl graphics. On top of that, the bundle comes with a Bravia 4K HDR OLED TV, a Playstation 4 Pro, Playstation VR, a year of Playstation Plus (the online multiplayer service), a Thrustmaster T-GT steering wheel controller, and an Apiga AP1 racing seat for playing the game. Oh, and of course it comes with a copy of the game. Funny enough, this isn't the first time a car has been offered as part of a video game bundle. When " Grid 2" launched a few years ago, the developer, Codemasters, partnered with BAC to sell a Mono edition. This special edition of the game came with a real life BAC Mono with "Grid 2" livery. There's no such thing as a free lunch, or a free car for that matter. At current exchange rates, the " Gran Turismo Sport" Super Bundle costs just shy of $46,300. Now that's a much more affordable proposition than the " Grid 2" BAC Mono package, which rang in at about $189,000, though the Miata is a much more affordable car with less performance. Americans shouldn't be disappointed the " Gran Turismo Sport" Super Bundle isn't available here, though. This is because the Super Bundle can be re-created here for much less money. Every item in the bundle plus a Miata Sport with a manual transmission and the Soul Red paint would come to a little under $32,000, a savings of over $14,000.
