You're comparing a car that is almost 50 years newer.
The emissions era really only served to strangle power output and destroy any classical romance in the American car market. Efficiency gains didn't really show up in American markets until some 30 years later in the late 90s at the earliest, until then everything was underpowered and anemic to satisfy EPA constraints.
Look no further than the 5.7L V8 C3 Corvette from the 70s way into the mid nineties when the LT1/LT4 were finally introduced. Until then you had 5.7 liter small blocks barely making 200hp because of emissions regulations.

I call it the "Era of Suck", and date it to the passage of the Clean Air Act of 1970, was thrown into full effect by the oil shocks around '74, and ended around '93, the last year you could buy a new car in the US with a carburetor.
Not to diminish the gains made by safety and environmental regulations, but more to point out that these regulations have side effects that may not be visible or significant to those buyers only interested in a transportation appliance, except for the mysteriously increasing purchase price.

What's equally self-evidently true is that we wouldn't have developed our current tech if it wasn't for regulations, and even with them we're too little too late.
