You would think there would be buyers lined up. The problem: Oil companies are making too much money under the current conditions. Why invest money when you don't have to?
 
That would be logical if the only potential investors were oil companies. But maybe the unbiased experts that other investors have had look at this, aren't as positive as you? There are all sorts of financial investors that would invest if the science is sound. There can't really be any oil company conspiracy, when the funds could be readily available from investment bankers in Hong Kong or Tokyo, or ...

Aftermarket Engines by kernick

So let me ask this. Say a company like Ford with a product mix heavily towards trucks and pickups, stays the same as 2020 approaches. Now physics being what it is, they can't quite get to 35mpg for their fleet, while still selling their full and mid-size trucks.
 
What is to prevent them from putting very small engines in them for the initial sale, have the customer take delivery, drive it home and then bring it back for an "aftermarket" Ford V-8 the next day. The truck would be manufactured with the engine mounts and such would all be ready for the V-8. The small engine would be sold back, and go from the dealer to Ford and then stuck in a Focus.
 
I just think there would be a lot of loopholes in this law, that will make the aftermarket thrive. I could also see a lot of sports-car being built with smaller engines tuned electronically for economy, and then you bring the car back in, get the supercharger strapped on, and then the ECU reprogrammed for performance.
 
I think people will still end up driving what they want, and can afford.

The day after the clean air nazis realize what's going on, they'll get a law passed limiting engine modifications to the original displacement and/or emissions footprint, which is more or less the case in Europe today.
 
Physics doesn't say that trucks can't get 35 mpg. Physics says that trucks with the aero of a brick, engines with pitiful power-displacement ratios, and the footprint of a handicapped school bus can't get 35 mpg.

You have something against clean air?
 
(we have asthma inhalers around this household, and I sort of like the idea of keeping the particulates down to a manageable level).
 
That said, I like the 35mph fleet idea more for the hope that I'll have more buying options that will still save me gas money. I'm too cheap to buy a car that doesn't get at least 20ish around town.

Well if the engineers at any of the auto manufacturers could do that, don't you think their company would want that design? If Chevy could make a truck with 35 mpg that had truck-capabilities don't you think that would give GM the whole market? and GM wouldn't do that?
 
Maybe you'd like to design that for them? You could probably make a few billion $'s!

I'm sure they could, but before now it wasn't a priority for them.
 
Anyway, start with a Holden Ute, bring the drag coefficient down to 0.275, install the 6-speed 2-mode hybrid with a 0.5 overdrive, and debore the 2.9 V6 diesel in the Euro CTS down to 2.5L for the mileage bump.

The new GM hybrid is not going to be worth much as a towing vehicle. It gives up about 25% of the towing capability of the smaller engined versions. Fine for soccer moms, not so good if you want to tow much of a trailer. I am all for a smaller V6 diesel engine in an SUV. I do not need to have a 0-60 MPH under 7 seconds.

I'm still trying to figure out how they managed to put two electric motors in the transmission and get it to tow less than the regular slushbox. It should be able to tow 25% more with the addition of the motors. The only thing I can figure is some cooling issue with the motor windings during extended use?
 
Also, the impending release of SAE towing standards is going to knock a lot of the puffery out of the current tow "ratings" anyway.

It is the same with the RX400h and Highlander Hybrid. The motors will probably over heat under heavy loads. Not much good off road in heavy snow or mud either.

Since this is about the best of any car, are you suggesting the truck will have a similar body to a Corvette?
 
As for the rest, yes you will see more diesels in trucks (and cars), but I don't think that powertrain you're envisioning is going to work well in sub-zero weather, snowplowing, or pulling trailers uphills. You need an adequate engine in trucks, for those times when the hybrid batteries are depleted, or just several years old and not recharging fully (like new).
