Chief Engineer: Next Gen Prius Will Get Better Gas Mileage, Cost Less

Toyota's Satoshi Ogiso and Bob Carter address the global media gathered in Ypsilanti for Toyota's Hybrid World Tour press event The chief engineer for Toyota's Prius program, Satoshi Ogiso, who is also managing officer of Toyota Motor Corp, gave some hints about the next generation of Toyota's highest profile hybrid car at a presentation held as part of Toyota's Hybrid World Tour, a press event that gathered together all of Toyota's hybrid cars sold around the world for the first time in one place, in Ypsilanti, Michigan, not far from Toyota's large R&D center in Ann Arbor. Ogiso, who oversees product planning and chassis engineering for Toyota, said that while the company continues to work on fuel cell cars and expects to be selling 10,000 or more fuel cell cars a year by the 2020s, Toyota is committed to the concept of hybrid cars that combine electric motors and combustion engines. Due to refinements in Toyota's Hybrid Synergy Drive, the next Prius will get ""significantly better fuel economy in a more compact package that is lighter weight and lower cost, Ogiso said. "The performance of this next generation of powertrains will reflect significant advances in battery, electric motor and gas engine technologies," the Toyota engineer said. He also said that while hybrid components will get smaller, the footprint and interior dimensions of the Prius will remain the same. Comparing a 10% gain in fuel economy to sprinter Usain Bolt taking a second off his world record in the 100 meter dash, Osigo said that Toyota is aiming at 55 mpg for the next Prius, compared to 50 mpg for the current model. In response to a question about when that next Prius will arrive in showrooms, Osigo gave the standard 'can't comment on future product plans' response but then pointed out that the first three iterations of Toyota's flagship hybrid were spaced six years apart, hinting strongly that the new Prius will be launched in 2015. That car's traction batteries will have a higher energy density, and its electric motor, though smaller, will put out more power. Toyota is also aiming for a thermal efficiency of 40% for the gasoline fired combustion engine, which would be the world's most efficient. Future models of the Prius may also feature a wireless charging system that Toyota will being testing next year. Ogiso said that the next Prius will be the first Toyota to use the company's New Global Architecture platform and it will have a lower center of gravity and better structural rigidity. Ogiso also addressed other alternative energy developments at Toyota, including hydrogen fuel cells and supercapacitors. While Toyota is already planning production fuel cell cars within the next decade, supercapacitors, which are used in Toyota's TS030 LeMans racer, also on display at the event, are not yet ready for use in a street car. from The Truth About Cars http://www.thetruthaboutcars.com
