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 RX-3 restomod makes Leno scream, us cheer

The Mazda RX-3 Savanna was the rotary-engined version of the Mazda 808 Grand Familia. Sold in the US from 1971 to 1978, the little Japanese fastback earned a reputation as an excellent racecar, winning events all over the world. A racing connection is how a fantastic 1973 restomod example owned by Savant Young made its way to Jay Leno's Garage. Young said that when he was a boy his uncle used to street race an RX-3, and Young liked how the RX-3 sounded and the fact that a tiny import could go up against and beat big V8s of the time. Leno admitted that he has no connection to the RX-3, saying it's not the kind of car he typically likes. But he liked Young's custom update so much that when he saw the coupe sitting outside the Petersen Museum in Los Angeles, he waited for the owner to show up. Young's changes over the 15 years he's owned the car include dropping in the rotary engine and running gear from the second-generation Mazda RX-7, bridge-ported and methane injected. At 15 pounds of boost he says it's putting out about 400 horsepower. The rear end comes from a Toyota Hilux half-ton pickup, to help put all that power down in a car that weighs maybe 2,100 pounds. The color is taken from the Lamborghini palette. Disc brakes all around, 14-inchers up front, control the velocity. Nothing controls the gas mileage, said to be "maybe 12 mpg." And nothing could stop Leno from whooping it up during the driver. Check out the fun in the video above.

Mazda: Penn & Teller

Mazda turned to magic to highlight its refreshed CX-5, bringing in Las Vegas staples Penn and Teller to saw the CUV in half. The glitzy spot has a very Sin City feel to it, although considering some of the ads we've seen tonight, it's short on shock value, humor and heart-tugging imagery. Have a look, though, and let us know what you think.
