Mazda MX-5 breeds upgraded Roadster RS in Japan

Fans of the new Mazda MX-5 Miata looking for something a little more performance-focused may be enticed by the new RS model. Unfortunately they'll have to go all the way to Japan to get it. Because Mazda will only be offering this particular version back home. The new RS version of the Mazda Roadster (as it's known in Japan) features a number of performance upgrades, although none of them specifically affect the engine or its output. The Roadster RS features Bilstein dampers and front suspension tower brace for better handling, along with bigger brakes for added stopping power, a retuned steering rack for sharper turn-in, and upgraded exhaust for a better sound. Inside it's also been treated to heated Recaro seats with Nappa leather and Alcantara trim and a nine-speaker Bose audio system. It also comes equipped with adaptive front lighting and high-beam control as well as lane-departure and blind-spot warning systems. Feeling left out yet? Don't be too disappointed, or book that ticket to Tokyo's Natita International Airport just yet. The Mazda Roadster RS only comes with the smaller 1.5-liter engine that produces 129 horsepower, which is significantly less than the 2.0L we get here at 155 hp. It does, however, come with the six-speed manual instead of the automatic. So while this may not be the most powerful version of the Miata, it may be the enthusiast favorite – at least in the JDM.

Mazda details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

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.
