Hey - all this is related to green politics - I just heard one of the scientists who was involved in the Intergovernmental Panel on Climate Change which Gore and all greenheads alike will reference admit that they are all wrong. Even if all of Kyoto was implemented on 7/100 of a percent in warming would be affected - its too small to measure. Maybe we should just ease off the green politics including CAFE cause it's all based on goofy evidence.

These had lousy emissions because of needing to mix oil and gas, but these new systems could make this a much more precise operation.

Add one additional overdrive gear to every car currently sold. Something that is only useful at speeds of 55MPH or higher, and watch fuel economy soar. I can't tell you the number of cars I've driven that are turning 3000RPM or more at 70MPH. It has nothing to do with a small engine with low torque... and everything to do with gear ratio. Put in another gear... drop those revs down to two grand and ride on. I was going to say. Add one additional overdrive gear to every car currently sold.

By making cars safer, they've also made them much heavier. Add all of the modern day comforts and amenities to all that safety and the problem gets even worse. You want an extremely fuel efficient car? Take out all of the strengthening beams, airbags, electronic traction/stability wizardry, emissions equipment, air conditioning (does anyone realize how much a condenser weighs!?!), heated and powered seats, power-everything, the 10-jigawatt stereos, automatic transmissions, etc... and we could have plenty of cars on the road hitting 70+ mpg.

Replace side-view mirrors with small cameras embedded in the front fender, with displays in the dash. I can't believe this isn't common practice nowadays, given how large mirrors are in the profile of the vehicle. Here is a quick Aerodynamic improvement.

The average vehicle has been gaining pounds on just about the same pace as most of our population. Therein lies the problem: it's easy to say you're going to have everything riding around on bicycle tires in the name of fuel economy, but most fat f*cks these days carry a way bigger spare tire than the one in the trunk.

I ride my bike to work on nice days. I'm not a hardcore cyclist who rides everyday, everywhere... just to work and back on sunny days. I fill my S-10 up about once a month. I probably get about 25 mpg, but one tank will last me several weeks. Makes the $60 fill ups less painful, when you can't remember the last time you did it. Deanster, good call.

Walk to the corner store, or bike to your friend's house if it's close enough. No reason to drive all the time. How about driving less in general?

How about dropping the mechanical fan on the the full-size trucks? Start/stop is coming this year, BMW is going to electric water pumps as well. Parasitic losses should be a no brainer.
