The Glorious Future
2012 should be 2020
“I used to have a 1966 GTO with a 6.5 liter (389 CID) V8 and a carburetor, and it got this kind of mileage or better. What gives?”
Several things:
1) We put more accessories on our cars now than we did back then. Power steering, power brakes, automatic transmissions, bigger alternators to power more electrical stuff.. all use energy.
2) Many people don’t know it, (I didn’t until I worked with some performance engineers that educated me) but pollution reduction strategies often compromise mileage.
I had a car with a small V8 (220 CI) that routinely got 26 mpg on the highway. This car was made in 1961. Manual transmission, no power steering or power brakes, but it sipped gas.
Were/are you the one driving a Yugo, because it was inexpensive and got good gas mileage? Meanwhile, all the hot chicks were riding in the Camaros and Firebirds and pickups.
If life were only about what was "practical", we'd all end up being Jimmy Carter.
Sorry. This is total B.S.
Rear wheel drive makes very little difference in fuel mileage. 1-3%, tops.
GM continues to ship pretty much every car it builds with an automatic transmission. That hurts their corporate average fuel economy much more than a switch to rear wheel drive would.
Those are the new, improved EPA fuel economy numbers. They are unrealistically low.
if any of these car companies had any balls, they would band together and “JUST SAY NO” we will no longer produce or ship any Vehicles of any kind in or to the US. Beginning today all new vehicles coming off of production lines are for export only.
Or they could just close their doors sell off everything and divvy it up amongst the employees as severance.
All it would take is them announcing this Publicly and the game would be over, Every City and State in the US has New Car Sales as their largest source of Sales Tax Revenue. Every Politician would be voted out tomorrow if not outright lynched in the public square.
I only wish they had the GUTS to Stand up and do the right thing, because I would If I were in their shoes, Starting with California. within 2 weeks the economy would be in a MAJOR Depression and the Politicians would be begging for forgiveness or in hiding.
Eyeamok
So what should they do instead, prove they know better than the customer by building stickshifts nobody wants to buy?
In most causes an automatic does better on the EPA treadmill test than the manual.
I’m glad I got my GTO when I did.
I can afford the gas.
God Bless America!
A torque converter is always going to be less efficient. That’s just physics.
If the government really wanted to encourage more efficient cars, it would promote the use of manual transmissions, among other things.
My point is that the “we can’t build rear wheel drive cars because of CAFE” whine is bull.
Ah, smog and bicycles. Gotta love it.
here’s a rather dumb question...
why doesn’t GM bring back a new version of the 53mpg 1993 Geo Metro xfi? that ought to go a long way towards having a fleet-wide average greater than 35mpg...
All else being equal, yes an unlocked torque converter wastes energy and the hydraulics to work the clutches waste more energy. But a computer controlled transmission working with a computer controlled engine can do things a stickshift can’t. For a known operating schedule like the EPA treadmill test, this can be gamed into a higher score by 1-2 mpg.
Rear wheel drive doesn’t give up a great deal of mileage. But in an environment where urban hippies are demanding the manufacturers build clowncars their customers dosn’t want to buy, they can’t afford to give up anything. That means RWD - and body panels you can lean on without denting, and side mirrors big enough to see out of, and trunks low enough to see over, etc - are getting the axe.
Because the same government that demands clowncar fleet mileage is simultaneously demanding cars be built with huge, heavy crash frames to let you walk away from driving into a brick wall at 40 mph.
GM can’t legally sell you that 2000 lb 50 mpg Geo any more, and when they finished putting 800 pounds of new safety equipment in it you’d be left with a 30ish mpg car like the Aveo they’ll already sell you.
The torque converter of an automatic is inherently loses more energy than the clutch of a manual. In the rare cases the auto version of a model does equivalent or better mileage than a manual in economy because of other compromises the manufacturer has made. Anytime the auto version gets better mileage than the manual on the same model you know the auto has at least one of two performance disadvantages: the gearing is taller or the engine is less powerful.
Another disadvantage of automatics is they require more maintenance, are less reliable, and cost more to repair.
As for customers, we don’t like automatics and the last time we bought a car I had to do a lot of research before I found a model that fit our needs and had a manual transmission available. Now we are in the market again, this time for a minivan, and would buy a manual if they made one. Unfortunately, the Mazda5 is the only minivan model with a manual option and it is too small for our needs. Even in trucks where manuals were the norm is is getting difficult to find one.

Then the Republicans will jump in and save us all by suggesting that we not make the rickshaws mandatory until 2028.
Those of us that try to resist will be told, "You can't win by loosing."
LOL...that’s about right.
