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:

Next-gen Toyota Tacoma to debut at Detroit Auto Show

Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups. The next generation of the Toyota Tacoma pickup truck will be revealed in January at the Detroit Auto Show, a top executive confirmed Thursday. Bob Carter, senior vice president of automotive operations for Toyota, offered no other details, but the new version of the pickup is expected to have significant upgrades compared with the aging model on sale now. Our spy shooters caught a prototype testing this summer, and rumors of the new generation have been swirling for months. We've also previously reported that Toyota is planning to ramp up production next April at a factory in Mexico that builds the Tacoma. Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups, the Chevrolet Colorado and GMC Canyon, which have garnered awards, positive reviews and solid sales since they arrived in showrooms this fall. It's unclear how large the new Tacoma will be, especially considering that the Canyon and Colorado flirt with fullsize territory. The Tacoma was last updated in 2012, and the segment has changed dramatically since then with the addition of the GM trucks. Another Tacoma competitor, Honda's aging Ridgeline, is also expected to re-launch in 2015, which would leave the Nissan Frontier as the oldest truck in the field. Tacoma sales have slipped 4.1 percent to 140,757 units this year, though they posted a 3.3-percent gain in November. Meanwhile, Carter also said Lexus will reveal two performance vehicles, though he didn't elaborate. "I'll leave it at that, but I promise you'll enjoy it," he said coyly. Lexus just showed the LF-C2 convertible concept at the Los Angeles Auto Show.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.
