Introduced in spring 2009, the all-new
2010 Toyota Prius has 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.
Credited with establishing hybrid technology as a foundation for
future vehicles, the three generations of the Prius model have
delivered superior fuel economy and ultra-low emissions for more than
1.3 million owners worldwide for more than 10 years.
The midsize third-generation 2010 Prius offers even better mileage
ratings, enhanced performance, and innovative design features. The
patented Hybrid Synergy Drive system in the 2010 Prius is 90-percent
newly developed, with significant improvements over previous models. The third-generation Prius is quieter and roomier than previous models,
as well. It is 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.
An Eco-Icon
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 hybrid car technology. At the
same time, the Prius helped boost public awareness for the automobile's
role in the environment, specifically putting a focus on improving fuel
efficiency and reducing carbon emissions. 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, nearly 700,000
Prius models have been sold in the U.S.
In designing the new, third-generation Prius, Toyota engineers
combined a careful refinement of existing systems with a leap in new
technology necessary for the future of automobiles. During the
development of the Prius, more than 1,000 patent applications were
filed worldwide.
Improved Fuel Economy, Power and Environmental Performance
The
new Prius is built using processes that reduce emissions in every stage
of the vehicle lifecycle, from production and driving, through to
eventual disposal and dismantling years down the road.
The 2010 Prius extends its record of continuous improvement in
fuel economy. The first-generation Prius was rated 41 EPA combined mpg,
and the second-generation model achieved EPA combined 46 mpg rating.
Using a combination of technologies, Toyota increased fuel efficiency
for the new Prius to an EPA estimated 51 mpg in city driving, 48 mpg
highway and a combined 50 mpg.
A larger and more powerful 1.8-liter Atkinson-cycle, four-cylinder
engine produces 98 horsepower at 5,200 rpm in the new Prius. Together
with its electric motor, the hybrid system generates a combined 134 net
horsepower, an improvement of 24 horsepower over the previous
generation.
The new, larger engine helps improve performance and also helps
improve highway mileage. The 2010 Prius can accelerate from zero to 60
mph in 9.8 seconds. By producing greater torque, the new engine can run
at lower average rpm on the highway, thereby using less fuel. Mileage
is especially improved in cold-start conditions and at higher speeds.
Use of an electric water pump and a new exhaust gas recirculation
(EGR) system also contributes to the engine's efficiency. The 1.8-liter
Prius engine is the first Toyota powerplant that requires no accessory
drive belts, helping enhance powertrain efficiency and also potentially
reducing maintenance costs.
Unlike many 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. With the
series-parallel Hybrid Synergy Drive system, Prius can operate on
electric power only and charge its batteries while running. Additional
hybrid performance improvements for the third-generation Prius include:
? The transaxle is lighter and reduces torque losses by as much as 20 percent compared to the previous model.
? The inverter, which converts direct current to alternating current, has a new direct cooling system to reduce size and weight.
? Taken together, the inverter, electric motor and transaxle are smaller and 20 percent lighter.
? A redeveloped electronically
controlled regenerative braking system has been adopted, with control
logic optimized to enhance regeneration.
The new Prius offers four driving modes ("Normal" plus three
more). The available 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. 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.
The new Prius is certified as a Super Ultra Low Emission Vehicle
(SULEV) and an Advanced Technology Partial Zero Emissions Vehicle
(AT-PZEV) in California, as well as those states adopting California
emission standards. The AT-PZEV certification requires the SULEV
exhaust standard linked with the ability to meet a
zero-fuel-evaporative standard, a 150,000-mile durability
demonstration, extended emissions system warranty, and technology
deemed by the California Air Resources Board (CARB) to advance future
fuel cell vehicles. In the rest of the country, Prius is certified as
Tier 2, Bin 3. The new Prius produces over 70 percent fewer
smog-forming emissions than the average new vehicle.
Striking New Yet Familiar Styling
In
designing the new Prius, aerodynamic performance was an important
factor, as was preserving brand recognition. The goal was to create a
striking yet still familiar silhouette, while not compromising
function. Designers preserved the dynamic triangle form of the current
model -- instantly recognizable as a Prius -- but made alterations to
the overall profile, pillar position and angle.
The overall height of the Prius is the same as the previous model,
but moving the peak 3.9 inches to the rear alters the roof profile.
This change maintains the wedge shape, and also allows for enhanced
rear headroom and improved aerodynamics.
The design of the new Prius' front and rear corners are sharp,
sporty and aerodynamic. Strong side character lines, rising from front
to rear, define the smooth, geometric shape. Viewed from the rear,
wider rear treads provide a solid, firmly rooted stance. The 106.3-inch
wheelbase is the same as the previous generation. Overall length is
slightly increased by 0.6 inches, in part by moving the front cowl
forward.
Super-Low Cd
The new 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 wheel face design, the designers
reduced 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.
Advanced Equipment for a New Era
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 helps keep the interior air temperature near
the outside ambient temperature, when parked directly in the sun.
Cool-down time is shorter when the driver returns to the vehicle, thus
reducing the use of air conditioning.
The new Prius also offers a remote air conditioning system. It is
the first system in the world to function on battery-power alone, and
allows remote operation so the driver can cool the interior temperature
for comfort before getting into 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.
Enhanced Vehicle Performance
The
third-generation Prius is built on a new platform that enables improved
handling control and quieter operation. The suspension employs front
struts and a rear intermediate beam design, as before, but smoother
handling is increased by improving the stabilizer layout, higher caster
angle and tuning the bushing characteristics. Four-wheel disc brakes
are standard, replacing the front disc/rear drum system of the previous
model.
Weight was saved through use of aluminum in the hood, rear hatch,
front stabilizer bar and brake calipers and by using super high-tensile
strength steel in the inner rocker panel, center pillar and roof
reinforcement.
Better-performing sound insulation, working with improved
vibration damping, has been installed in various locations to reduce
road noise.
Functional Interior Is Bigger on the Inside
The
cargo area of the new Prius was made 0.4 inches longer and 2.2 inches
wider by using a new and an improved layout for the battery cooling
unit. Rear seat legroom is enhanced by a new space-saving contoured
front-seat design.
Viewed from the cockpit, the center cluster smoothly flows from
the instrument panel to the console. Handy storage space has been added
under the shift lever by taking advantage of the shift-by-wire system.
Simple, fin-type air vents are consistent with the cabin's efficient
appearance. Judicious use of silver accents adds a finished, technical
feel.
A new available 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 display in the instrument panel. The ECO indicator on
the Multi-Informational Display (MID) provides driver feedback to
encourage more economical driving.
In pursuit of new technologies for sustainable mobility,
Toyota uses plant-derived, carbon-neutral plastics in the 2010 Prius.
Known as "ecological plastic," the new material is used in the seat
cushion foam, cowl side trim, inner and outer scuff plates, and deck
trim cover. Ecological plastic emits less CO2 during the production
process than conventional plastic; it also helps reduce petroleum use.
Safety Enhancements
The new Prius was designed
to comply with class-top level collision safety performance in each
global sales region, and to accommodate increasingly strict safety
requirements in the future. In addition to a driver and front passenger
Advanced Airbag System, front and rear side curtain airbags, driver and
passenger seat-mounted side airbags and driver's knee airbag are
standard equipment.
Active headrests are used in both front seats to help reduce
the possibility of whiplash injury in a rear collision. Anti-lock Brake
System (ABS), Electronic Brake Distribution (EBD), Brake Assist (BA),
traction control (TRAC) and enhanced Vehicle Stability Control (VSC)
are included with Toyota's standard Star Safety System?.
A Dynamic Radar Cruise Control system, using advanced
millimeter wave radar, is an available option. The system also enables
Lane Keep Assist, which helps the driver stay within the lane, and the
Pre-Collision System, which retracts seatbelts and applies the brakes
in certain conditions when a crash is unavoidable.
Third-generation Intelligent Parking Assist features
simplified settings to help guide the car into parking spaces. A backup
camera, 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,
emergency assistance button (SOS) and roadside assistance (1-year trial
subscription included).
