The 2010 Toyota Prius offers better mileage with enhanced performance in comparison to its previous models.

The electric motor is called a permanent magnet synchronous motor which can out put 80 horsepower with a 153 lb-ft torque. The Hybrid system net outputs 134 horsepower. The hybrid battery pack is nickel-metal hydride.

Environmental Friendly and Fuel Economy

The 2010 Toyota Prius has a combined mileage rating of 50 miles per gallon. It comes with a 1.8-liter Atkinson-cycle engine which will power the new Prius Hybrid with four-cylinders. The automobile makes use of an electric water pump and a new exhaust gas recirculation (EGR) system which contributes to the engine’s efficiency.

The vehicle also requires no belts under the hood for better fuel economy and less potential maintenance. This is one of the reasons why this is an eco-friendly car. The driver can also receive feedback, from the multi-information display panel, which can provide help to acquire economical driving habits.

Hybrid Synergy Drive System

Prius has been a full hybrid since its first introduction over 10 years ago. This allows the automobile to run on engine alone, battery alone, or a combination of both. This system blends the best of parallel hybrid to achieve the ability to operate on the electric mode alone, and to charge the batteries while the car is running.

The Hybrid Synergy Drive system in the 2010 Prius is 90 percent newly-developed with significant improvements over previous models. The transaxle is lighter in weight and reduces torque losses by as much as 20 percent in comparison to the previous model. The inverter, which converts direct current to alternating current, has a new direct cooling system to reduce size and weight.

The car has adopted a new electronic controlled braking system with control logic optimized to enhance regeneration. The Prius offers three alternatives for driving which include EV-Drive Mode, Power Mode, and an Eco Mode.
