The auto companies have not invested in efficiency because there's only a small market for it. The vast majority of people want size, horsepower, or both. This is why the Prius production numbers are kept small and there's a waiting like. The 70MPG cars rarely make it out of the computer because there's no market for them. Some of the technology does, but then it's sold as technological innovation not efficiency. For example BMW has a 12 Cyclinder engine that shuts off a bank at cruising speeds and many new MBs have dual fuel engines (petrol/ethanol). If you look at the new cars that are coming out it's size (Cadillac Escalade) or speed. There's a bunch of cars out now that are 300bhp+ out of the box (Subie WRX STi, Mitsu Evo 8, Chevy Corvette C, Cadillac STS-v, Dodge Magnum, etc.) and the supercars are super fast not super efficient (Chevy Corvette Z, Dodge Viper, Ford GT, etc.) The last time someone tried a super efficient car it bombed. The mid-ninties Geo Metro got near 70 MPG when driven right. Where are they now? The engine technology was there over a decade ago: "I have a 1991 Geo Metro, I have installed a cat back exhaust system, a K&N aircleaner, ram air, a performance camshaft, underdrive aluminum pulleys, MSD ignition coil, 8 degree advance cam sprocket, and a resistor for my AIT, I get an honest 53 mpg at over 70 miles per hour........I am installing headers next month,the car has 168,000 miles on it an has been overheated 12 times by my son,and I have ran out of oil completely a few times, this is an amazing little engine......I have a more powerful engine almost ready to go in as soon as this one dies, but I have been waiting a long time for this one to die." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Discover CFTicket - The leading ColdFusion Help Desk and Trouble Ticket application http://www.houseoffusion.com/banners/view.cfm?bannerid=48 Message: http://www.houseoffusion.com/lists.cfm/link=i:5:157095 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/5 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:5 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
