Do The Figures
Add Up?
Hybrid cars are the new environmentally
aware way to drive. They are very fashionable among the young
professional classes at the moment, and a great way of
displaying your green credentials to the world.
Although the ecological advantage may be the main factor in
your wish to buy a hybrid car the cost implications are
important and it is worth having a look at the main points and
how the costs ad up.
Until now, many that might otherwise have purchased a hybrid
car have been unsure as to the cost benefits of this new breed
of automobile. While the environmental advantages have always
been clear, the cost advantages have not. The average hybrid
cars can produce anything between 20-90 pre cent less emissions
than its gas guzzling counterpart. The 90 per cent being
achieved while primarily using the electric motor at low speeds
around town. There has always been an uncertain cost analysis
as to whether buying a hybrid car saved you money in the long
run, or actually added to your motoring costs.
Hybrid cars have always maintained a price premium compared
to their more conventional counterparts due to the cost of the
extra, and much more complicated technology involved. This is
not only due to the separate electric motor that is needed to
power the car but also to the need for seamless integration of
the two power sources when switching from one to the other.
And also there aware other expensive features in hybrid cars
such as weight reduction, generating capacity to top up the
batteries and regenerative braking that all add to the higher
cost of hybrid cars. This is used when the car is braking,
instead of the brakes being applied to slow the car the
electric motor is engaged without power and so runs backwards.
The drag from this assists the braking motion and at the same
time generates electricity for the batteries. This effectively
saves power that would otherwise be lost
All of these systems on hybrid cars are expensive to produce
and thus the cost of a hybrid cars is usually well above that
of a similar, traditionally powered model. The argument over
this has always been that you recoup these initial outlays in
the lower running costs. This became an especially valid
argument after the recent, dramatic rises in fuel costs, a
trend that looks set to continue for the foreseeable
future.
But does it all ads up? Is the fuel cost saving with hybrid
cars enough to offset the original cost outlay? Or is running a
hybrid car just an expensive way of helping the environment
while leaving you poorer, despite the considerable saving in
fuel costs?
