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:

Toyota previews next Lexus RX with Tokyo-bound JDM Harrier

The Lexus RX shares much with the Toyota Highlander, but its more direct counterpart is the Toyota Harrrier. Never heard of it? That's because Toyota only sells it at home in Japan, and now it's revealed a new one. So if the Harrier is essentially a Toyota-badged version of the RX, then what's the big deal, you ask? The big deal is that the new Harrier which leaked in July, set to debut at the Tokyo Motor Show next week and which you see here isn't quite the same as the Lexus, and those differences could (and in most cases likely will) make their way over to the RX as well.
For starters, the styling is different. Granted that the Lexus version will almost certainly get a spindle-shaped grille, but even so, the Harrier's nose seems to protrude further than the RX's and the headlamps are a notably different shape. The greenhouse is also a different shape, coming to a sharper point at the back, and the mirrors are fixed to the A-pillar not to the door panel. The taillamps are revised, the tailgate has a new profile and there's a pseudo-diffuser at the bottom of the rear bumper. Subtle changes, to be sure, but then Toyota and Lexus are known for their evolutionary approach to styling. The interior has apparently undergone some updates as well, with a more dynamically styled dashboard, a more symmetrical center stack and different seats, steering wheel, door panels... the works. The infotainment display screen has also moved further down from its position in the current RX.
Toyota will offer the new Harrier with a 2.0-liter four mated to a CVT and driving either the front wheels or all four, and a hybrid setup with a 2.5-liter married to a 140-hp electric motor. The RX is offered here with a 3.5-liter V6 either on its own or with an electric assist. We wouldn't expect Lexus to go swapping the larger engines for the smaller ones, at least not for the US market. There's plenty more to the Harrier, of course, than the similarities and differences to the Lexus RX, and if you're buying a premium crossover in Japan, you can delve into the full details in the press release below, together with the images in the gallery above.

Toyota's future fuel cell vehicle lineup revealed?

Being an Olympic sponsor from 2017 through 2024 puts Toyota in the international limelight, and the company is preparing a fleet of efficient, cutting-edge vehicles just in time for the Tokyo games in 2020. At least eight new models could be on the way, according to Automotive News citing Best Car from Japan. Three of those might make use of the hydrogen fuel-cell powertrain developed for the Mirai. While many of these fuel cells are going into Japan-only vehicles, one of them could come here. Reiterating earlier rumors, Automotive News reports a hydrogen-powered Lexus LS is set for 2018. It could be even lighter than the current hybrid model, too. A similar version of the Toyota Crown would launch there in 2019 and possibly an FCEV Estima minivan, too. Beyond fuel cells, Toyota also intends to put the JPN Taxi Concept from the 2013 Tokyo Motor Show into production in time for the games, according to Automotive News. For 2017, the brand's flagship Century is also expected to adopt a hybrid V8 to replace the current V12, as well. Plus, many of its Japanese-market vans are also due for updates. All of this is certainly a massive undertaking to be ready in time, but Tokyo want to use the games as a chance to show the city as an innovative, international destination. Automotive News predicts Toyota could supply thousands of vehicles to haul all of the athletes and dignitaries around. In addition, the Japanese government wants 6,000 fuel cell vehicles on the road and 35 refueling stations up an running for the games. Related Video:
