How platform problems are delaying next-gen Prius

Short-term pain for longer-term gain? That may be the prognosis for the next-generation Toyota Prius, the world's best-selling hybrid. But, hey, the new version might get holiday season debut, now. Toyota is upgrading some of its most popular models and trying to cut long-term costs with components that can be used on multiple models on the new Toyota New Global Architecture platform, Automotive News says. That means more parts that can be used for the Camry, Avalon (not big stretch, since the Avalon is basically a rich man's Camry) and Corolla in addition to the Prius. The downside, of course, is that this takes a bit more engineering and certainly more time. In the case of the Prius, that means pushing back the start of production from next summer to December 2015. But Automotive News also says the Prius may have an all-wheel-drive option. Happy Holidays. The report is in update from Automotive News Europe, which cited folks familiar with the process who were not identified and said late last month that the production of the fourth-gen Prius would be pushed back by about six months as engineers continue to tweak the hybrid powertrain for maximum efficiency. The goal is around a 10 percent improvement in fuel-efficiency thanks to an upgraded powertrain and lower vehicle weight. Toyota spokeswoman Amanda Rice told AutoblogGreen in an email that the company doesn't comment on future products, so we'll just have to keep an eye out.

The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.

Scion rules out roadster, turbo versions of FR-S

Ever since Toyota and Subaru released the sports car alternatively known as the GT86, 86, BRZ and Scion FR-S a couple of years ago, rumors have circulated that even more exciting variants could be in store. But at least as far as Scion is concerned, those rumors are apparently nothing more than wishful thinking. Speaking with WardsAuto at the LA Auto Show last week, Scion chief Doug Murtha said that the prospect of an FR-S roadster has been taken off the table entirely. Apparently Scion lobbied parent company Toyota to produce just such a model, but after failing to find other markets interested enough in the model to put it into production, corporate HQ said no. "I think we were pretty aggressive on our (submitted plan), but we looked at what we would have conceivably lost on the product and said, 'We're not going to even push it further,'" Murtha said, going on to note, "Nobody was more disappointed than we were." Murtha further shot down the idea of a turbo version of the FR-S, dismissing it as a prospect the blogosphere (that's us) wanted to happen but "that's not something that's coming." Either variant might have helped Scion and Toyota boost sales of the model (which are predictably dropping after their first two years on the market), but the investment also might not have paid off their development, tooling and marketing costs. Of course, Murtha can only speak for Toyota, but we'd be surprised to see Subaru go it alone on either model, as costs would be that much more prohibitive without a partner. Bummer.
