Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

Evo blasts around in a Spa 24H-winning Mazda RX-7

Think of the Mazda RX-7 today, and your thoughts likely turn to the turbocharged third-generation version of the '90s that's an icon among the tuning and drifting communities. Many years before that swoopy coupe was hanging the tail out, the first model of RX-7 was also quite a track star, though. Evo's Richard Meaden has gotten ahold of a race-prepped version that counts a victory in the 1981 Spa 24 Hours to its name – the first Japanese car to claim that honor – for a fantastic video. With 225 horsepower and weighing around 1,984 pounds, this RX-7 doesn't look like a giant killer on paper. However as Meaden illustrates, the coupe puts those rotary-powered ponies to very good use. Driving it requires constantly keeping things on the boil because the muscle is essentially absent below 7,000 rpm. Once in the sweet spot, things start progressing quickly, though. As a wonderful cap to the wall of noise from the engine, little licks of flame also shoot out of the exhaust on downshifts. Thankfully, Evo's video team captures all of the mechanical noises quite well, and the clip is a treat for those with a good pair of headphones. Despite the race-winning pedigree, Meaden has no problem grabbing the little coupe by the scruff of the neck. He chucks it through the corners to get the tail loose, and the little wisps of smoke from the rear tires prove the original RX-7 knows how to drift too. These early cars definitely worth being remembered in the pantheon of Mazda performance.

Mazda CX-3 details come to light

Mazda may be working on a new CUV, according to Auto Express. Reportedly called the CX-3, the small crossover will be engineered to take on the likes of the Ford EcoSport and Nissan Juke, but with a focus on fuel efficiency and engaging driving characteristics.
The report names no sources, but says the CX-3 will benefit from a new small-displacement diesel engine. The 1.6-liter oil burner will be joined by a 1.3-liter gasoline engine when the vehicle debuts in 2014. Auto Express reports the model may bow as a front-wheel drive offering only, with no all-wheel-drive option.
And what will it look like? Word has it Mazda will continue to leverage the face we've seen on the current CX-5 (pictured). That means the company's shield grille will make the jump, but with more plastic lower body cladding. Inside, Auto Express says the CX-3 will offer buyers fold-flat rear seating for extra cargo capacity.
