I'd heard years ago from a friend of mine who'd worked as a mechanic in the Army that US car manufacturers have known for years how to design an engine to get 45-50 mpg or more, but didn't make them for political reasons.
Of course they know how to design an engine that gets 45 MPG -- it's called small and less powerful than the 200+ HP beasts that grace a lot of vehicles these days. If you'd like to try one, buy a decade-old Honda CRX or a new VW Jetta TDI.
Of course, car companies could also build a much bigger car (an SUV or full-sized sedan) that got somewhat better gas mileage than the current ones do, but they don't, because
surprise, surprise most people these days (certainly the ones who drive SUVs) prefer power to fuel efficiency, even with gas in the US approaching $3/gallon (where I live, anyway). They also don't want to bother spending the money on R&D if the government isn't going to force them to with stricter standards--why bother, if it's not a big selling point compared to even more power?
I really find the ongoing urban legends about the miracle 100MPG car that was never built because the oil companies wouldn't want it amusing; why would a car maker care one way or the other what the oil companies think? It's not like if you make Texaco angry they're going to stop selling gas for your cars, and if somebody compares your 20MPG SUV to a competitor's 50MPG SUV, which one do you think they'll buy?
Even if it were a US government conspiracy (again, I don't quite see why they'd bother--people still seem to use more than enough fuel), then why aren't these miracle engines available in Europe, Japan, or Korea? Because they don't exist.
You can buy a fairly efficient car right now, it's just going to be a lot smaller and less powerful than what most US consumers seem willing to put up with. Wonder if that'll change when gas hits $5/gallon.
