Dodge Challenger

The 2021 Dodge Challenger SRT Hellcat has mastered Darwin's theory of evolution, transforming into a more fascinating machine year after year. Although a supercharged 6.2-liter V-8 is still at the heart of this big-bodied Dodge coupe, the Hellcat engine now comes in three eye-popping potencies: 717, 797, and 807 horsepower. 

The two-door Hellcat obviously has a personality disorder, and its available widebody kit, various appearance packages, and predilection for smoky burnouts have made it a YouTube star. Sure, its interior quality doesn't match the lineup's lofty price tags, but the 2021 Challenger SRT Hellcat's visual presence and powerhouse engines do: it's one of the most powerful machines in the world—and looks it.

For 2021, there's a new Challenger Super Stock model that's essentially a detuned version of the drag-race-ready SRT Demon that was limited to a one-year production run. The Challenger Super Stock boasts an 807-hp version of the enhanced Hellcat engine that powers the Redeye. Every SS features a widebody kit, a revised powertrain calibration, and a specially tuned suspension that optimizes quarter-mile performance. It also has lightweight equipment that includes all-aluminum Brembo brake calipers and downsized 14.2-inch rotors as well as 18-inch-by-11-inch wheels wrapped with Nitto drag radials that measure 315/40R-18 at all four corners. The SS also inherits components that were found on the Demon, such as a line-lock feature for heating up the rear tires and a "Race Cooldown" system that ensures the engine stays at an optimum operating temperature.

The Widebody version both handles better and looks cooler, so that's the one we'd choose. Despite the fact that the SRT Hellcat is all about excess, we wouldn't opt for the Redeye model that increases power to nearly 800 horses. In fact, during our testing, the Redeye wasn't quicker than the standard Hellcat because its tires couldn't put the extra grunt to the ground.
