After teasing us for months with photos of switches and boot up screens, followed by a leak of the whole car, Toyota finally dropped the third generation 2010 Prius today in Detroit. We already heard many of the mechanical details over the past year or so, but today it was confirmed that the Prius will get a combined EPA rating of 50 mpg. That's 50 mpg under the new tighter EPA testing method, mind you. The engine has been up-sized to 1.8L with an output of 98 hp and the total net output of the hybrid drive system is 134 hp.

The basic design is still instantly recognizable as a Prius, but the body does have a bit more character than before. Nonetheless the shape is smoother with a drag coefficient of just 0.25. The peak of the roof has now been moved back 4 inches giving the car a slightly less egg-shaped profile and increasing rear headroom. Aside from optional extras like LED headlights and lane departure prevention, the most interesting new option is the solar roof. A roof-mounted photo-voltaic panel will power the air recirculation system when the car sits in the sun, reducing the internal temps and the subsequent load on the air conditioning system. The Prius goes on sale later this spring but pricing hasn't been announced yet. Hit the jump to view video of the live press conference.
