America’s Cars Are Suddenly Getting Faster and More Efficient
Half of today’s vehicles blow away the baddest rides of the 1970s. But the reasons are more complicated than you might think.

Sometime in the next couple of months, the Dodge Challenger SRT Demon and its 808 horsepower will show up in dealership windows like some kind of tiny, red, tire-melting factory. Yes, 808 horsepower. There’s no typo.
Teenage boys will lose their minds. Some older ones, too. But beyond the Vin Diesel fan club, it’s actually not such a big deal anymore. Last year, U.S. drivers on the hunt for more than 600 horsepower had 18 models to choose from, including a Cadillac sedan that looks more swanky than angry. Meanwhile, even boring commuter sedans are posting power specifications that would have been unheard of during the Ford Administration.
