50 MPG with Additional Horsepower, New and Innovative Technology, Improved Aerodynamics, More Head and Legroom

The all-new 2010 Toyota Prius will once again set new standards for innovative hybrid design and technology, raising its level of convenience features and performance to new heights, including a combined EPA estimated fuel efficiency rating of 50 miles-per-gallon.

Celebrated as the benchmark for cars of the future, the Prius has delivered superior fuel economy and ultra-low emissions to more than 1.2 million owners worldwide for more than 10 years.

The midsize third-generation 2010 Prius will offer even better mileage ratings, enhanced performance, and innovative design features. It will be quieter, roomier, and equipped with advanced standard and available features such as a moonroof with solar panels, four driving modes, Intelligent Parking Assist (IPA) and steering wheel touch controls that display on the instrument panel.

Prius entered the market in 1997 as the world’s first mass-produced hybrid.

The name Prius, “to go before” in Latin, became symbolic of a car that was launched even before environmental awareness had become a mainstream social issue.

From the beginning, Toyota’s full-hybrid system was developed almost entirely in-house and has become a driving force behind advanced vehicle technology. The company’s exclusive Hybrid Synergy Drive System was introduced in 2004 on the second-generation Prius. Since then, more than 700,000 have been sold in the U.S.

The new Prius will be built using processes that reduce pollution in every stage of vehicle life, from production and driving, through to disposal.

The third-generation Prius extends its record of continuous improvement in fuel economy. The first-generation Prius, which was rated 41 EPA combined mpg, was replaced by the current model, which is EPA rated at 46 miles per gallon (mpg), combined city/highway.

Using a combination of technologies, fuel efficiency was increased to an EPA estimated city/highway mpg rating of 51 in the city, 48 on the highway and a combined 50 mpg for the new Prius.

A multi-information display panel that monitors fuel and energy consumption is standard. It provides feedback on the Prius’ efficiency using three different displays to help the driver acquire economical driving habits.

Unlike most other hybrid vehicles available, Prius has been an uncompromised “full” hybrid since introduction. This allows it to run on engine alone, battery alone, or a combination of both. The system blends the best of parallel hybrid and series hybrid designs to achieve the ability to operate on the electric mode alone, and to charge the batteries while the car is running.

The new Prius will offer three alternative driving modes. EV Mode allows driving on battery power alone at low speeds for about a mile, if conditions permit. There is also a Power Mode, which increases sensitivity to throttle input for a sportier feel, and an Eco Mode, which helps drivers achieve their best mileage.

The third-generation Prius received more wind tunnel hours of testing than any other Toyota in history, resulting in one of the cleanest aerodynamic profiles of any mass-produced vehicle in the world.

By focusing on the shape of the body, underfloor, wheelhouse liner and shape of the wheels, the designers of the new Prius were able to reduce the coefficient of drag (Cd) value to 0.25, compared to 0.26 for the previous model. The airflow under the car was studied extensively. Engineers made changes to the shape of the fender liner, front surface of the underfloor, and added a fin at the rear floor cover to increase linear stability.

An available sliding glass moonroof is packaged with solar panels, located over the rear seating area, that power a new ventilation system. This solar powered ventilation system uses an electrically powered air circulation fan that does not require engine assist. The system prevents the interior air temperature from rising while the vehicle is parked, making the cool-down time shorter when the driver returns to the vehicle, thus reducing the use of air conditioning.

The new Prius also offers a remote airconditioning system. It is the first system in the world to function on battery-power alone, and allows remote operation so the driver can adjust the interior temperature for comfort before getting in the car.

LEDs (light emitting diodes), optional in low beam headlamps and standard in tail and stop lamps, help reduce the vehicle’s power consumption. Air conditioning, a major energy drain, has been re-engineered to increase efficiency and cool-down performance.

In addition, an exhaust heat recirculation system reduces heat waste by warming engine coolant during cold startup, for improved performance. It also heats up the passenger cabin more efficiently.

The next-generation Prius is built on a new platform, which enables improved handling stability, quieter operation, and collision safety. The suspension consists of front struts and a rear intermediate beam design, as before, but handling stability is advanced by improving the stabilizer layout, a higher caster angle and tuning the bushing characteristics. Disc brakes are now used on all four corners, replacing the front disc/rear drum brakes in the current model.

Proving that small changes add up to big gains, the cargo area of the new Prius was expanded 0.4 inches in length and 2.2 inches in width by using a new and an improved layout of the battery cooling unit.

Rear seat legroom is enhanced by a new space-saving contoured front-seat design.

A new Touch Tracer Display features touch sensors on the steering wheel switches that are designed to reduce driver eye movement for better concentration on the road. When the driver touches the audio or info switch located on the steering wheel, a duplicate image is displayed on the instrument panel, directly in front of the driver. Touch Tracer is the first display system in the world to allow steering wheel controls to read out on the instrument panel.

In pursuit of developing various advanced technologies aimed at realizing sustainable mobility, Toyota will use plantderived, carbon-neutral plastics in the 2010 Prius. The newly-developed plastics, known as “ecological plastic,” will be used in the seat cushion foam, cowl side trim, inner and outer scuff plates, and deck trim cover. Ecological plastic emits less CO2 during a product lifecycle (from manufacturing to disposal) than plastic made solely from petroleum; it also helps reduce petroleum use.

The new Prius was designed to comply with class-top level collision safety performance in each global region of sale, and to accommodate increasingly strict safety requirements in the future.

In addition to advanced driver and front passenger Supplemental Restraint System (SRS) airbags, front and rear side curtain airbags, driver and passenger seat-mounted side airbags and driver’s knee airbag are standard equipment.

An available option is a Dynamic Radar Cruise Control system, using advanced millimeter wave radar. The system also enables Lane Keep Assist, which helps the driver stay safely within the lane, and the Pre-Collision System, which retracts seatbelts and applies the brakes in certain conditions when a crash is unavoidable.

A backup monitor, which provides a view of rear obstacles when reverse is engaged, is available with an optional voice-activated navigation system. Safety Connect, Toyota’s first safety and security service, includes automatic collision notification, stolen vehicle locator and an SOS call button. Safety Connect will be available a few months after launch.

The Prius will be available in seven exterior colors including Blizzard Pearl, Sandy Beach Metallic, Blue Ribbon Metallic, Winter Gray Metallic, Classic Silver Metallic, Barcelona Red Metallic and Black. They will be mated to three interior colors that include Misty Gray, Dark Gray and Bisque. All three interior colors will be available in both fabric and leather.
