I have a problem with them too. They're so ineffective as to render themselves unnessessary.
Just by lowering the drag coefficients of todays cars from .32 to .20, we could increase combined fuel economy by roughly 25%, with no engine, transmission, or tire modifications and no weight reduction. Adressing aerodynamics would add very little to the cost of a vehicle and if done right would not affect the vehicle's practicality. Hybrid drive trains, CVTs, LRR tires, diesel engines, and other advances would allow for even more gains.
One only needs to look at cars that have been built as prototypes to understand what is and isn't possible.
You may want to google search the following:
*Opel Eco Speedster(diesel), 94 mpg combined fuel economy, 160 mph top speed(electronically limited), 0-60 mph in 8.9 seconds, sports car
*GM Ultralite(gasoline), 88 mpg, 135 mph, 0-60 in 7.8 secs, compact
*Loremo LS(diesel), 157 mpg, 100 mph, 0-60 in 19 secs, sub-compact
*Loremo GT(diesel), 88 mpg, 138 mph, 0-60 in 9 secs, sub-compact
*VW 1 Litre(diesel), 235 mpg, 78 mph, sub-compact
*Jetcar 2.5(diesel), 87 mpg, 100 mph, sub-compact
*VW Lupo 3L(diesel), 79 mpg, 102 mph, 0-60 in 12.7 secs, compact
*Mercedes Bionic(diesel), 55 mpg, 118 mph, 0-60 in 7.9 secs, compact
*Ford Prodigy(diesel-electric), 72 mpg, 80 mph(lim), 0-60 in 12 secs, midsize
*GM Precept(diesel-electric), 80 mpg, 85 mph(lim), 0-60 in 11.5 secs, midsize
*Dodge Intrepid ESX3(diesel-electric), 72 mpg, 90 mph(lim), 0-60 in 11 secs, midsize
*VW Ecoracer(diesel), 69 mpg, 143 mph, 0-60 in 6.3 secs, sports car
*Audi A2 3L(diesel), 78 mpg, 105 mph, 0-60 in 13 secs, compact
*Renault Twingo SmILE(gasoline), 71 mpg, 93 mph, 0-60 in 14 secs, subcompact
*VW Wundercar II(diesel), 118 mpg, 112 mph, 0-60 in 12 secs, subcompact
*Vapor Fuel Technologies Alé(gasoline), 92 mpg, 140 mph, 0-60 in 5 secs, single person commuter
*Opel Astra ECO4(diesel), 54 mpg, 109 mpg, 0-60 in 13.5 secs, compact
*Mitsubishi i(gasoline), 62 mpg, 115 mph, 0-60 in 10.6 secs, sub-compact
The typical American midsize sedan accelerates 0-60 mph 10 seconds, tops 115 mph, and gets ~27 mpg on gasoline. Considering the above, isn't that embarassing?
Basically, we could have had since the 1990s 70 mpg midsize cars that do 0-60 mph in 11 seconds, 90+ mpg sports cars that top 160 mph, 80 mpg compact cars that perform adequately on the highway, and 150 mpg fuel misers. All with today's off the shelf technology. Even as far back as the 70s, by addressing aerodynamics, we could have had 30+ mpg V8 musclecars.
I'm not a big fan of regulations, but if they are to exist, at least make them effective. Either scrap the CAFE standard altogether, or make it an immediate 60+ mpg fleet average.
