Next Toyota Prius coming in 60-mpg 'Eco Grade' version?

There's some mystery surrounding the fuel economy level of the next-generation Toyota Prius. The closest we've had to an official number is 55 miles per gallon, which was hinted at by Toyota Motor Corporation's managing officer, Satoshi Ogiso, last year. That number wasn't an official target, but the company even provided a graphic (above) showing how each next generation Prius beat the previous one by four or five mpg. Since the current, third-gen model gets 50, well, we have been left to guess that 55 is the next logical target. But, according to a new report in Automotive News, the new, fourth-generation Prius that's due next year will come in two versions, with one having a bigger ego – sorry, eco – than the other. AN says that the model will arrive with a standard nickel-metal hydride battery pack in a version that gets "about 55 mpg" and then a new "eco grade" version with a li-ion battery that "will be rated at more than 60 mpg." AN says this information came from company executives who were speaking at an August meeting with Toyota dealers. Our sources within Toyota say that they haven't heard anything about two high-efficiency models, so we'll take this with the requisite grain of salt. The current version of the Prius Plug-In Hybrid does use lithium-ion batteries, but this is the non-plug model the dealers are talking about. We think. The dual-battery strategy is certainly a rumor we've heard before. We had thought that the li-ion pack would be for an extended EV range (the current Prius has a barely noticeable EV-only range), but such a pack would be lighter and could boost efficiency, too. In other words, we look forward to hearing more during the upcoming auto show season.

Lexus LX to get diesel engine?

Australian consumers appear poised to get another diesel-burning luxury SUV in the near future, and word is it's coming from Lexus, of all automakers. Sean Hanley, chief executive of the company's branch in Oz, recently told Aussie website Drive that he's "pretty confident" that the new engine for the LX is getting the green light.
Like in the US, the LX in Australia is currently only offered with a 5.7-liter, gasoline-burning V8. However, sales of the big SUV are presently minuscule Down Under, with Drive reporting just 153 LX570s sold in all of Oz last year. Hanley is negotiating with Japan to get the new diesel in hopes of boosting flagging sales. If his efforts are successful, it would be the first diesel engine offered in a Lexus there. Hanley didn't specify exactly which mill the SUV would get. However, given the LX's close relationship with Toyota Land Cruiser, the diesel 4.5-liter twin-turbo V8 already available in the Toyota in markets outside of North America seems like a natural choice.
Don't expect the variant to be hopping across the Pacific, though. Lexus spokesperson Allison Takahashi tells Autoblog she has heard "nothing" about an oil-burning LX coming to the US. That's not a huge surprise, though, because neither Toyota nor Lexus offer any diesels in their lineups today. Also, Lexus has only sold 1,981 LX570s through June, which only placed it ahead of the LFA supercar in the brand's sales. It's probably just not worth certifying the engine for such a low-volume model.

Ex-Toyota Bill Reinert still in favor of hybrids, against EVs

Former Toyota executive Bill Reinert is so unsold on electric vehicles as a viable advanced-powertrain option for future transportation that he has praised – gasp – Ford, for its downsized internal combustion engines. Reinert was a key player in developing Toyota's original Prius hybrid and, in an interview published in Yale University's Environment 360 blog, said a hybrid that gets 60 miles per gallon is superior to an electric vehicle. "And that is why you will be seeing more fuel cells in the future." – Bill Reinert Reinert went on to praise the advances that automakers have made in improving fuel economy of fossil fuel vehicles, specifically namechecking Ford and its three-cylinder Ecoboost engine. He also has good things to say about both hydrogen fuel-cell electric technology as well as natural gas vehicles, but admits that limited fueling infrastructure will keep those types of vehicles in the margins for the near future. He also says that hydrogen vehicles aren't that great yet but that, "When most [manufacturers] investigate the two technologies [H2 and EVs], they see that FVCs offer more room for performance improvement and cost reduction potential. And that is why you will be seeing more fuel cells in the future." As far as pure electric, Reinert says lithium-ion batteries have "tremendous shortcomings" and talks about battery degradation, substandard performance in hot weather and, of course, limited single-charge driving range. He also says that people need to factor in the environmental impact of producing electricity for the grid to fully gauge how environmentally beneficial EVs can be. We'd like to take him and Tesla Motors Chief Elon Musk to what we think would be a spirited lunch. You can read the whole interview with Reinert here.
