Toyotas third-generation petrol-electric Prius hybrid is expected to make its world debut at the Detroit Auto Show in January next year before going on sale in Japan and the U.S. in April. The changes planned for the new model will be minimal, as these latest spy images of a near-production-ready prototype reveal.
Key differences compared to the current model will be a slightly larger body, a more spacious interior and a more upmarket feel. The car will sport a distinct nose and tail design, and both its wheelbase and track will be increased. Designers are determined to ensure the new model will be instantly recognizable as a Prius.
The Hybrid Synergy Drive system will carry over largely unchanged but the current 1.5L engine will be replaced with a more powerful 1.6L unit. Power will be increased but fuel-economy will better the current models EPA rating of 48mpg in the city (4.9L/100km) and 45mpg (5.22L/100km) on the highway.
Despite being bigger and more powerful fuel consumption will be improved. Toyota will do this by installing a more efficient powertrain with improved batteries for longer electric-only driving plus a lighter body thanks to extensive use of advanced composites in its construction.
A new battery factory being constructed in Japan will ensure there are no delays in the supply of nickel-metal hydride batteries for the new Prius, and will suffice until a lithium-ion plug-in version is released in 2010. Other updates include the possible addition of solar roof panels to help power the cars auxiliary items such as the air-conditioning and electronic steering system.
Pricing is expected to fall slightly above the current cars $22,160 base price in the U.S. but any increase will be modest. Toyota is also expected to launch a new family of Prius models so there could be a wagon variant and possibly even a convertible further down the track.
With Toyotas Mississippi plant now confirmed to start building the Prius in 2010, production numbers for the new model will reportedly be increased by as much as 70% - up to 480,000 units annually to help meet soaring demand.
