I just find it a bit sad that mileage doesn't seem to have improved. I've got a '97 Hyundai Elantra GLS that gets around 35mpg highway. Some of the hybrids available today don't even match that, and the more efficient gas-powered cars I found are still right around there.
14 years have gone by since my car was made. Where are the improvements in efficiency?
I imagine it's close to as efficient as it'll get. You can cut weight, displacement, and improve aerodynamics, but you're still squirting gas into a hole, and igniting it. You could lean out the mixture, but then it would overheat. You could then increase heat tolerance, but that would add weight, so you're back to where you were. Most people wouldn't buy the funny looking cars it would take to get better mileage.
