Bigger engine, more power, scoops, and wings for Mustang Shelby GT500

On Monday morning, the second-worst secret in Detroit finally got its official reveal. I am of course referring to the newest, fastest, and biggest-grilled (that's a word) Ford Mustang ever, the Shelby GT500. (Number one is obviously the mid-engined Corvette C8.) Under its now-bulging hood is a supercharged version of the 5.2L "flat crank" V8 that sounded so good in the Shelby GT350. The addition of some forced air will give the GT500 "more than 700 horsepower" (522kW), according to the spec sheet—full figures will have to wait until closer to the car's showroom arrival later this year. To cope, it gets a new dual-clutch transmission from Tremec; sorry stick shift fans, there is no three-pedal option this time.

The rest of the car takes this same approach: start with the GT350 then turn everything up to 12 (because 11 is passe.) The scoops and vents are bigger, because the more powerful engine and stronger transmission need more cooling. So, too, do the brakes, similarly supersized—the front rotors now measure 16.5in (420mm) which is a hefty increase in thermal mass. It's the front that dominates the GT500's appearance. Ford says it has double the open area of the GT350—a stat we don't doubt—and that cooling airflow is 50 percent higher.

There's revised suspension geometry to cope with all this excess, and like the Mustang GT we tried driving last year, there's a full suite of track-biased electronic trickery on offer from the MagnaRide suspension and the powertrain. If you opt for the Handling Pack you get some additional goodies, including adjustable strut top mounts and a spoiler with a Gurney flap. Or you can go for the Carbon Fiber track package, which includes carbon fiber wheels (slightly wider at the rear), ultra-sticky Pilot Sport Cup 2 tires from Michelin, the adjustable wing and splitter from the GT4 Mustang race car, and no back seats.
