At last: the 2010 Toyota Prius, making its world debut at the 2009 North American International Auto Show.

Here’s the skinny from Toyota’s Group VP Bob Carter, who introduced the car at the Detroit auto show:

• 50 mpg combined — the highest-mileage car sold in the U.S.
• Most aerodynamic production vehicle in the world, with a drag coefficient of .25
• Three driving modes: EV, economy, and power
• 0-60 in about 9 seconds (a noticeable improvement)
• Solar sun roof powers an interior cooling fan while the car is parked
• Sales start in late spring 2009 in the U.S. and Japan
