The 2010 Toyota Prius is set to achieve a combined city/highway EPA estimated fuel efficiency rating of 50 miles-per-gallon, the highest ever for a consumer retail vehicle. The original Prius came in at 41 MPG, and the current model gets 46 MPG.

Although Honda is boasting [2] that its upcoming Insight hybrid will get over 65 MPG under ideal conditions, the 2010 Insight only gets about 41 MPG combined [3] (it has not yet been EPA tested).

Pricing on the 2010 Prius has not yet been announced, but it will go on sale in the spring.
