Yeah, I'm still getting 47MPG with my '92 GEO METRO!!!No
air,1625 lbs with 1/2 tank fuel, 3 cyl, 5 speed. Such progress
we've been making :)
Dan F
Yup, you have to love progress. 1970 Mazda 1200 Coupe' got 40 MPG.
Same body as a R100 but a piston engine with carb. R100 had some
braces to stiffen it, so it was about 100# heavier. 1200 Coupe'
was about 1700#. Went like stink with a RX2 engine.
Dale Davies
Same goes for my RX2. Weight was 2300 pounds while my RX8 is over
3000 pounds with essentially the same weight engine. There was
more interior room in the RX2.
Perhaps we are letting the wrong people make decisions.
When first introduced, the Volt carried a $41,000 sticker, though
it qualified for a $7,500 federal tax credit. Is this the GM EV
allover again? Why are we, the taxpayers, having to subsidize
these unpopular cars?
Paul Lamar
Yeah but ..... did your RX-2 have door guard beams and crash
worthy,energy absorbing bumpers, catalytic converter and other
smog paraphernalia and a plethora of air bags plus air
conditioning, power windows, remote locking, seat belts and crash
worthy seats ... even cup holders? That and dozens of other
mandated features have driven car weight upwards and made engines
less efficient.
It is easy to carp about car design but difficult to do in
practice in todays regulatory environment.

My point exactly. My RX2 had air as I recall and seat belts.

In Russia/Ukraine they have an expression; smart people, stupid
machine. In the western world we have to make the machine smart to
protect stupid people.I worked with a fellow whose expression is;
stupidity is God's way of controlling population growth.In about
'74 the RX2/3 cars gained 300 to 400 pounds due to impact bumpers.
Dale Davies
My point exactly. "Detroit" is not full of stupid engineers. They
are doing their best but when you have to meet all the government
mandates for door guard beams and 5 MPH bumpers and crush spaces
and safe gas tanks and airbags and seats that are completely crash worthy
and doors that will still open and close after various barrier
crashes at 30 MPH and up and catalytic converters and fuel fume traps
... plus all the amenities that the market demands today like dual
DVD players and on and on!
It used to be that there were plenty of cars on the market that
weighed less than a ton .... nowadays it is almost impossible to find
anything weighing less than 3000 pounds ... a 50% increase. Yet,
when I was a child, 15 highway MPG was considered good and now we see
lots of cars that can make 30+ MPG on the highway.
I think the engineering skill is there but the market is entirely
different as is the regulatory climate. Remember that old Toyota
ad slogan that went something like "you asked for it, you got it!"
There are lots of really good, clever people at the various car
companies ..... and they are giving us what we have asked for, both
in the showrooms and the halls of government. Does anyone want to
blame Ralph Nader?
SD
How about the EPA and the congress.

My note did say "have to build" implying regulations. No insult
intended to the engineers. It is the general public that is not so
brilliant. We all have moments where we have a lapse.
Dale Davies
Most days I'd like a car that weighs less, eliminating some of the
safety features.. But once in a while, a car that I'm sharing the
road with does something really stupid, and then I'm happy with the
extra stuff I haul around every day...
I don't drive a big car - a Subaru Outback. Then to I have a '66
F100. The Outback has all its metal on the inside - the body skin
is very light, and easily dented. The F100 has all the metal on
the outside - seems tougher, but I'm sure it's much less
crashworthy. They are within about 100lbs of the same weight.
If I were always on the road by myself, I'd probably drive
something a lot lighter..
Matt-
The F100 is a Ford pick up truck for those that may not know.
Thinner, higher strength steel (may be heat treated after forming.
Expensive!) would help.
Another possibility to reduce the weight is foam certain cavities.
Mazda already does that in the RX8.
Paul Lamar
Right.. Here's mine:
Matt
You ought to put a 3 rotor in there Matt :)
Paul Lamar
Hi Matt,
That looks good. I am an old car guy also.
My father worked for the provincial government. One of the lawyers in the
office went to the government auction and bought an old Bronco, the first
series. It had been in the Forest Service Dept. and bounced off trees and
rocks. The 5 gallon gerry can on the back like you see in the WW2 movies might
have held one gallon. It looked like hell, but was mechanically in good shape.
Dad said when you drove with him, the traffic parted around him like the Red
Sea for the Hebrew people with Moses.
If you drive what looks like beater that survived a demo derby, nobody wants
to take a chance being close. I want to find an old Mack Model B. Tough as
granite and bigger than most citizen vehicles on the road so even in the event
of a tangle your chances are good.
