At a glance, this topless 1974 Ford Bronco looks every part the classic S.U.V. it is.

But pop the hood and discover a supercharged 700-horsepower Coyote V-8 engine, whose low, throaty rumble helped draw a crowd to the Bronco’s parking spot outside the New York Public Library on Fifth Avenue. The time warp continues inside, where contemporary creature comforts await. An infotainment system? Check. Fancy carpeting and heated seats? A six-speed automatic shifter? Yes to all that, and to its complete lack of drama.

Unlike some high-performance cars of the period, the Bronco doesn’t overheat or refuse to idle smoothly, and it handles and stops much better than any 1970s Ford product ever did. Climbing into a cab raised more than five inches was simple, thanks to running boards that slide out when the doors are opened. And 16 miles per gallon combined isn’t terrible, considering the power on tap.

The Bronco is a so-called restomod, a fast-growing category of autos built not just for gearheads who like to get under the hood but for families that simply like the look of old cars .
