Ford Escape Hybrid
In June 2005, the City of Pickering
purchased a Ford Escape Hybrid. Based on the success of this
initiative the City has purchased an additional 4 hybrid vehicles. The Ford Escape Hybrid can be
powered by either the gasoline engine or the electric motor, or by both
working together.
The operation of the vehicle can be
separated into four stages:
- As you slow to a stop, the gas engine
turns off to save fuel, but the engine continues in the electric
position.
- The electric motor will power the
vehicle up to 40 km/hr; therefore as you travel through subdivisions,
are in heavy traffic or are stopped you are not burning fossil fuels.
It is important to note that more greenhouse gases are produced during
slow or stop & go driving and this is typically when traditional
gasoline engines are least efficient.
- As you increase the vehicle speed past
40km/hr, the vehicle automatically and smoothly transitions into using
the gas engine. The gasoline engine of the hybrid is used when the
vehicle is at a higher speed where it can operate with the least
amount of harmful greenhouse gas emissions being produced.
- As you come to a stop, the electric
motor and regenerative braking system capture the energy that would
normally be wasted; when the brakes are activated, the electric motor
converts the vehicle's momentum into electric energy. This energy is
then stored in the battery for later use.

Something to Consider
A traditional combustion engine with a
battery-electric component gives the hybrid the driving range and rapid
refuelling option of a conventional vehicle, together with energy and
environmental benefits.
In general, the hybrid-electric vehicle
will produce 28 percent less emissions than a conventional gasoline
vehicle and reduce fuel consumption by 50 percent!
