Toyota has set a Geneva debut for the new Toyota Prius. The green machine will also go on sale in the U.K. later this year.

The third-generation Toyota Prius will finally hit the European stage next week in Geneva. Rated at 50 mpg in the U.S. (about 60 miles per Imperial gallons), the car should be quite a hit.

Do not let the "official" fuel economy figures fool you. Some publications have tested this car under real world scenarios, and gotten up to an astounding 65 mpg, or 78 mpg in the U.K. This car is not simply a revision of the second Prius. Over 90% of the car's parts are new, with improvements coming from a new engine, revised powertrain, and modifications to the car's shape. Rear passengers get more headroom from the peak of the car being pulled backwards. In the end, the car's drag coefficient was improved to .25 from .26.

On top of being more lightweight, it also gets more power. The new beltless 1.8-liter four cylinder gets 98 hp and 105 ft-lb of torque, a nice step up from the 70 hp and 82 ft-lb produced by the old 1.5-liter four cylinder engine. Despite the better power, the overhauled powertrain has helped to reduce CO2 emissions to 89 grams/kilometer. The driver will also enjoy a new heads-up display, solar-powered airco, and parking assist.

In the U.K., the new Toyota Prius will hit showrooms this July.
