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.

An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.

Recharge Wrap-up: Toyota HQ goes solar, CARB fights methane

Opel denies allegations about illegal emissions software as the German transport ministry begins its review. Opel has turned documents over to German authorities, and promises to hold a "constructive dialogue" while answering any lingering questions, says the automaker. Opel says that "the allegations reflect a wrong understanding of how diesel engines work." As German magazine Der Spiegel renewed questions about a cheat device similar to those used by Volkswagen, Opel reiterates, "We do not have any software that recognizes whether a vehicle is undergoing an exhaust emissions test."

French industrial gases company Air Liquide manufactures liquid hydrogen, while Korean automaker Hyundai has already deployed its Tucson Fuel Cell crossover in select markets around the world. The two companies have signed a deal to cooperate on hydrogen technology. President Park visited an Air Liquide research center during a trip to Europe, where she said that a partnership between Hyundai and Air Liquide can help their countries stay ahead in the fuel cell vehicle market.

The system, treatment, operation, and device standards would apply to onshore and offshore oil and gas production, storage, processing, and transmission facilities, covering procedures for leak detection and repair, equipment replacement, record keeping, and data reporting. "Methane emissions from the oil and gas industry contribute to California's [greenhouse gas] emissions and cost-effective reduction opportunities already exist and are available for use in the sector," CARB says. "In addition, reducing methane emissions from this sector will help slow the rate of climate change in the near-term and have an immediate beneficial impact on climate change." A hearing is scheduled for July 21 to discuss the proposal. Read more from SNL. Toyota's new Plano, Texas campus will get 25 percent of its energy from the sun. As Toyota plans to move into its new North American headquarters next year, it is building a 7.75-megawatt solar system to provide renewable energy for its operations. The solar arrays will be built atop three parking structures by the end of 2017.
