20 Ways to Boost Fuel Efficiency
5/21/2014

Image 1 of 20      Next >

Theoretically, the plug-in hybrid can achieve extraordinary fuel-efficiency numbers, given the proper driving schedule. Volkswagen's proposed XL1 is one such vehicle, reaching 261 mpg, the automaker says. To accomplish that, the XL1 employs just about every imaginable fuel-efficiency technology, including a 47-HP turbo-diesel engine, a 27-HP electric motor, carbon fiber-reinforced plastics in its monocoque, body panels, and anti-roll bars. The brakes also use carbon fiber ceramics, while the engine crankcase, steering gear housing, dampers, and other suspension components are made from aluminum. Even the XL1's windows were designed with weight reduction in mind, all of them being made from polycarbonate.  (Source: Volkswagen)

Change the carburetor

Gas mileage will go up when they change how efficent the carburetor is.

Until that happens we will always have low mileage.

Poor efficiency carburetor= Poor mileage. And thats all there is period.

Why isn't anyone trying to improve the carburetor?????

The 'cylinder deactivation' is a pretty ingenious solution at increasing a vehicle MPG rating. It's even more surprising that it comes from GM, perhaps it will be something that's 'recalled' in the future.

Remember the old (and I do mean old!) V8-6-4?  I think that was ... late-70s Cadillacs, was it?

Or....you can just ride a vintage motorcycle!  I ride everyday and use about 3 gallons a week! 

Seems efficient to me.

i'd say there is lots of room to improve efficiency, but it means spending money.

 

1) Maximize aero.  put the least drag out there, play with noses, tails, covers,

 

2) hybrid electric, plug in hybrid EV,  that's a big deal.

 

3) Minimize weight, drop spare tires, go to aluminum, go to fibers, plastics

 

4) advanced engine cycles.

 

5) Minimize rolling resistance

 

6) Program routes, auto convoy,

Path, I have already optimized one of my routes to minimize our stop signs, which the city management loves stop signs, 4-way stops even more. Adding a few turns that require letting off of the gas is not so bad, avoiding about 8 stops in two miles is good. Adding a heavy tax on things that impede traffic flow, incresing both fuel consumption and pollution that results, might be a good idea. They may even be able to balance the budget with all thqat extra income.

The hills thing is an interesting concept, probably congress would vote it into law if it were presented. BUT some cities are so flat that it would not be possible. How many hills are there in Phoenix, Az?

This idea is quite fascinating. It will eventually increase the mileage that drivers cover with there vehicles. This idea will boost the economy and encourage more people to get there hands on vehicles. This has made the work of tax payers easier and efficient. It is amazing that the vehicles will be much lighter since they will have lighter body weight parts, there will be less wiring on the vehicles and the engine technology will be much more boosted. I am definitely looking forward to these innovations.

i think on average you end up with the same altitude per round trip  but

you could design a trip to minimize stop lights

Cabe, when I lived in Huntsville Alabama and went to Lee High school, I did have that option. One route was downhill most of the way to school, while another route was downhill most of the way home. Of course there was quite a height difference between where the two routes left the school grounds, but that doesn't count in this discussion. (Known as the method of selected data)

That idea is half-genius!  (Or is it that half of that idea is genius...?)

Get thee to a patent office!
