fourth generation toyota prius production delayed six months

Once set for production in the spring of 2015, the fourth generation of Toyota’s Prius will instead enter production beginning in December of said year.

Automotive News Europe reports the delay is due to engineers wanting to massage as much fuel economy as possible, along with adjustments to the chassis and body. The confirmation model of the new hybrid is expected in November 2014, 12 months before production is set to begin; the plug-in variant will follow in October 2016.

Though Toyota declined to clarify the reasons behind the delay, managing officer for product planning Satoshi Ogiso said the new hybrid will serve as a test bed for the automaker’s modular Toyota New Global Architecture and a new hybrid system that will be more compact and lighter than the current system while delivering a thermal efficiency rate above 40 percent. The system will also support a wider range of engines and vehicles beyond the Prius and Camry hybrids.

    Toyota, having the technical supremacy for many years with their HSD system, most certainly has been scared with Honda's "Earth Dreams" serial hybrid system.

      @RogerB34 Dr. Kenneth Noisewater: "Volt’s crummy off-the-shelf lump is indeed not an Atkinson cycle motor (A14LUU)" Too true. Given that GM spent all that money on developing the Volt, it has always amazed me that they settled for such a mediocre engine.

    Because GM is....well.....GM? Now speaking seriously, there is a difference. The Honda "regular" hybrid is not designed to be a plug-in hybrid, which the Volt is. A better comparison would be the Accord "plug in" version.

    Delayed six months? Bummer. I know the Prius gets a bad rap, but I actually think it's kind of cool and am curious to see what the fourth-gen will look like (hopefully nothing like that dreadful fuel-cell vehicle) and what it will bring in order to defend the hybrid crown.

    "...engineers wanting to massage as much fuel economy as possible, along with adjustments to the chassis and body." - as an engineer, this statement makes me smile. If you are going to delay production, its because you want to make a better product. Not because of marketing, suppliers, bad aluminum, or forgetting to properly program your transmission. Kudos for management for not pushing out a product for the sake of meeting deadlines.
