Toyota is developing a range of Priuses that will include a small pickup based on the 2008 A-BAT concept and a sporty, 2+2 coupe to compete with Honda's upcoming CRZ hybrid coupe. The Prius coupe will have a lower roofline than that of the all-new 2010 Prius hatchback sedan launching this year and will share its powertrain.The 2010 Prius sedan's battery technology is carried over from the 2004-2009 model, but its 1.5-liter engine may get a small bump in displacement or power output with no penalty in fuel economy. Since the 2+2 coupe will be significantly lighter than the hatchback sedan, having the same powertrain means it will be quicker and faster. Think 1984 Honda CRX with a standard Civic four-cylinder.
