About the Prius V
The Prius V wagon joins the PRIUS, CAMRY hybrid and HIGHLANDER hybrid as a
hybrid model for Toyota.
Hybrid Synergy Drive means that the vehicle contains a
gasoline engine and an electric motor for power. The two hybrid power sources are
stored on board the vehicle:
1. Gasoline stored in the fuel tank for the gasoline engine.
2. Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack for the
electric motor.
The result of combining these two power sources is improved fuel economy and
reduced emissions. The gasoline engine also powers an electric generator to recharge
the battery pack; unlike a pure all electric vehicle, the Prius V never needs to be
recharged from an external electric power source.
Depending on the driving conditions one or both sources are used to power the vehicle.
The following illustration demonstrates how the Prius V operates in various driving
modes.
n
During light acceleration at low speeds, the vehicle is powered by the electric motor.
The gasoline engine is shut off.
o
During normal driving, the vehicle is powered mainly by the gasoline engine. The
gasoline engine also powers the generator to recharge the battery pack.
p
During full acceleration, such as climbing a hill, both the gasoline engine and the
electric motor power the vehicle.
q
During deceleration, such as when braking, the vehicle regenerates the kinetic
energy from the wheels to produce electricity that recharges the battery pack.
r
While the vehicle is stopped, the gasoline engine and electric motor are off, however
the vehicle remains on and operational.
