DETROIT — The most powerful street-legal Ford Mustang ever built will go on sale this fall.

A 5.2-liter supercharged V8 will crank out 760 horsepower in the 2020 Shelby GT500.

The new version has a beefed-up suspension and brakes. It also has a seven-speed automatic transmission that Ford promises will shift smoothly on commutes and quickly on the track. The engine is hand-built at a Michigan factory and comes with unique pistons and other parts. It can crank out 625 foot-pounds of torque, a measure of rotational force.

The Shelby GT500 can go from zero to 60 mph in around 3.5 seconds, although Ford didn’t release a precise number. That’s slightly slower than the midengine 2020 Chevrolet Corvette, which General Motors says will do it in under 3 seconds.

The car starts at $73,995 including shipping and a $2,600 gas-guzzler tax.
