One of the vehicles being heralded as the way
to go is the Toyota Prius. This is Toyota’s dual powered
vehicle. It is a hybrid with both internal combustion and
electric power. These were shown at the Bangkok International
Motor Show in 2001, and our Down-under correspondent, John
Weinthal has just spent some time with one. Here are the Words
from Weinthal.
“This week we have tasted what could be the
future of motoring. I approached Toyota’s minimum-emissions,
maximum-economy, dual power-source Prius in a decidedly
sceptical mood. My “Green” credentials are only marginally
better than those of the Environment Ministers, Lord Mayors and
others who cruise our streets in their V8 limos, while spouting
on about the end of the world if the rest of us don’t mend our
ways.

“In reality, the Prius matched just about
all that Toyota claims for it - and they make some impressive
claims, believe me. This is - let’s be diplomatic here - a
distinctively styled conventional four-door, five-seater sedan.
In fact few cars have attracted more ‘love it/hate it’
comments on their looks. But the buyer will decide what he
thinks before purchase.
“Toyota’s asserts that its alternative
energy vehicles must drive like normal cars - or better. Prius
comes mighty close to that.
“Toyota makes impressive claims about big
reductions in all major noxious exhaust emissions. We don’t
have the scientific equipment to check that out, but others do,
so it is certain they would not exaggerate on that score.
“Toyota says Prius should use up to 50
percent less petrol than a similar-sized car like their own
Corolla. Presto; the test car averaged over no-tricks, normal
everyday city and highway cruising just 5.1 litres of petrol per
100km. That’s around 60mpg in the old money.
“Prius has two power sources. There’s a
conventional but advanced 53 kW, twin cam 1.5 litre, four
cylinder which does most of the work in moving this 1250kg
sedan. The really clever bit is the electric motor which
imperceptibly takes over when power demand is lower. When using
the air-con, as we did over most of our week and 550 km, the car
runs on petrol. However, when braking or coasting, the petrol
engine recharges the electric motor’s 274 kW nickel metal
hydrate battery by what is known as regenerative braking. The
petrol engine automatically switches off when the car is
stationary for more than a few seconds, restarting the moment
you press the accelerator. That’s just one of the initially
eerie but ultimately appealing features of the car.
“There is no conventional transmission,
hence no engine braking. An artificial, apparent engine braking
can be introduced by moving the driving wand. We used this
occasionally when approaching a roundabout for instance.
“Prius can be extremely quiet, especially
on start-up and reversing which is always performed using the
electric motor. At one stage on a freeway run we noted that the
digital speedo was pointing some way above the limit. I didn’t
expect a speeding ticket in Prius, but it would not be
impossible. Around town the car stays with and ahead of the
general melee and often I forgot that I was driving something
‘different’.
“The ride can be a fraction harsh on bad
surfaces at low speeds thanks to the low profile, low rolling
resistance tyres and handling has a distinct touch of understeer.
Neither is a big issue at any time.
“Standard equipment includes two air bags,
climate control air conditioning, ABS anti-lock brakes, power
windows and mirrors, a quartet of cup holders, electric power
steering and a six-stack in-dash CD player. The test car had an
optional combination touch-screen audio and satellite navigation
centre similar to Lexus we have driven recently.
“So, Prius proved to be a more than
satisfactory everyday car. At AUD 40,000, initial buyers will be
mainly government and others who wish to flag their Green
credentials, and private buyers who like to be first with the
latest. Neither is likely to be disappointed.
“Prius carries a normal three year/100,00km
warranty plus six years for the no-maintenance battery which
Toyota says should last the lifetime of the car. That’s a good
thing as a replacement would currently cost around $6000!
“The only major warning is not to run out
of petrol then try getting home under electric power. You
won’t, and you will destroy your six grand battery.
“On some levels Prius offers genuinely
appealing advantages in everyday use, quite apart from its
economy and any feel-good factor you may garner from believing
you are helping keep our planet spinning.
“Toyota themselves declare that this is the
new beginning. It’s a more than satisfactory start, believe
me. We will see - and buy - many more hybrids of this ilk within
a decade.”
