Notice that key word SHOULD, also what are they antisipating the life of
the vehicle? I expect at least 150,000 out of a vehicle with MINOR
repairs.

Gee there is that SHOULD word again. You might want to look at many
vehicles that have had CVT transmissions and you will discover that they
no longer do, because they don't last in the real world.

With normal oil changes this little item has been shown to be a non
issue in todays vehicles. Also if they are using a different pump to
build oil pressure that is one more item to fail that a conventional
engine doesn't have.

Well we made it from Should to Could. Oh and FYI NOBODY drives that
carefully. The other minor thing is that the brakes DO engange at every
stop they have to since they are the same as the brakes used on 99
percent of Toyotas autos. The difference is when you slow down some of
the energy is returned to the battery pack by the wheel motor.

No just constant starting and stopping of the engine depending on how
you are moving the throttle. Real poor trade off there.

Since most gas engine provide enough torque to move a vehicle at idle
speed I'd love to know where the "few thousands" comes in. 99 percent of
vehicles out there don't even turn a "few thousands" at redline.

Sounds like double talk to me. The Prius and the Escape are BOTH assist
hybrids. And they DO have the exact same problems as a "regular" car
since they have the same drivetrain, they just add extra crap on to make
it a hybrid.

Topic: Reality check- hybrids, fuel efficiency
Well, some people think hybrids are the greatest thing since sliced
bread. And maybe they have a point . But let's get something straight.
When you are driving a hybrid, you are not "saving the planet".
In Europe they have much higher fuel economy than the US on average. The
average German car gets 40 miles per gallon. Yet they don't have many
hybrids over there . The Prius has sold very poorly in Europe. So how do
they get the good economy, then?
1) Smaller cars appropriate to their needs. Europeans don't buy a pickup
just to drive to work. I lived in the UK in the late 80's and the only
people with pickups lived in rural areas, and they never drove them for
commuting. SUV's were nonexistant, except for some Land Rovers that a
few people in rural areas or workers used (to actually haul things). Now
days its pretty much the same.
A car about the same size as a Honda Civic is considered a "midsize" car
in Europe. In the US, it's considered small, but in Europe it would be
considered a family car. Cars the size of a Honda Insight are very
common.
2) More efficient engines. Lean burn gasoline and diesel engines. And
lots of turbochargers. Turbochargers aren't just for performance cars,
they capture waste energy from the engine and enhance the efficiency.
It's far more cost effective to build a turborcharged engine than to
build a hybrid.
Also, it should be pointed out that riding a bus is far more energy
efficient than driving a hybrid ever will be. Sure, not everybody wants
to ride a bus, but you are saving more fuel and emiting less greenhouse
gasses than driving around even in a hybrid.
So what's my point? Toyota has the Prius. It's got alot of technical gee
whiz stuff. But if they were serious about "saving the planet", every
car they built would be a hybrid. Instead, Toyota and other automakers
want to use hybrids to raise their CAFE average so they can sell more
gas guzzlers at a profit (Toyota even tried to petition CARB in
California to let them offset Prius sales with more Land Cruiser and
large SUV and truck sales- but they failed). Or they want to apply the
HSD technology to gas guzzlers, and make them only a little less gas
guzzling so they can meet CAFE standards while continuing to sell
oversized, overweight, ill-handling SUV's to the public.
Prius is a big marketting plus for Toyota. It attracts customers to
dealerships and gives Toyota a good image with the public, enhancing the
prestige for every single car they sell. When they don't have a Prius on
hand, they can always try to sell them something else, too. Again, if
they were serious about selling cars with the HSD and inccreasing the
fuel economy, they would be making lots of small hybrid cars, not SUV's.
Instead, only a small fraction of all cars they make are hybrids. Their
next planned hybrid is a large SUV that will consume more gas than many
smaller cars or station wagons. Ford's first hybrid was a small SUV that
barely gets the gas mileage of a small station wagon like the Toyota
Matrix. Dodge's first "hybrids" were large trucks with very poor fuel
economy. SUV's and trucks every where, but this is hardly energy
efficiency. One guy driving to work in an overweight, overpowered hybrid
car or SUV is not saving the planet.

I thought this thread is about "battery life" including Lead Calcium Alloy,
Lead Antimony Alloy, Hybrid Lead Calcium - Lead Antimony Alloy, and
Low Antimonial Lead Alloy B A T T E R I E S.
99% of the ACDelco Freedom Batteries for domestic US-Canadian cars
are Lead Calcium Alloy.
Who cares about non GM Electric Hybrid Cars when the Battery cost per
KG outweighs the benefit to the ecology.

The reason for the should word is easy
They have only recently started to be produced
They have an excelent track record so far
They should be able to last a long long time and get high resale value
Those that have been resold have in many cases been higher than new
prices
Thing is it is a long que for these hybrid cars and it is difficult to
get one
There is no need to advertise because the demand is way higher than
supply
The producers are very careful of not producing many because they want
production to grow slowly while they gain experience with these hybrid
cars at customers
Everything looks like this is a huge success
Many who do not get a hybrid are not too happy otherwise it is fine
The repair men are not too excited because it will mean a lot less for
them to do
Everyone want to know how they age
What you should do is wait
Ageing takes time
