Priced from $60,365, the Mustang Dark Horse remains one of the few traditional muscle cars still in production. For those seeking the ultimate track experience, Ford also offers the exclusive Dark Horse R, a purpose-built race variant that pushes the boundaries of Mustang performance even further. This enduring appeal solidifies the Dark Horse’s place as a modern icon in the muscle car pantheon.
Chevrolet Camaro Z/28 (Fifth-Generation) — 505 HP
The fifth-generation Chevrolet Camaro bid farewell with a formidable track-focused variant, the resurrected Z/28. Making its debut in 2014 and continuing through 2015, this iteration marked the return of a legendary nameplate not seen since 2002. While the fifth-gen ZL1 held the horsepower crown with 580 hp, the Z/28 carved its own niche as a driver’s car, boasting 505 horsepower and 481 lb-ft of torque from its naturally aspirated 7.0-liter LS7 engine—a member of the revered LS engine family.
Chevrolet’s objective with the Z/28 was not mere straight-line speed but rather track dominance. The engineers prioritized weight reduction through extensive use of lightweight materials, complemented by Multimatic Dynamic Suspensions Spool Valve dampers for superior handling. The car rode on ultra-wide Pirelli P Zero Trofeo R tires, providing exceptional grip, while Brembo carbon ceramic brakes delivered fade-free stopping power. An aggressive aerodynamic package generated significant downforce, further enhancing its track credentials.
The Z/28’s performance was nothing short of spectacular. MotorTrend clocked a 0-to-60 mph time of 4.0 seconds and a quarter-mile time of 12.3 seconds at 117.2 mph, figures that remain impressive even by 2024 standards. This blend of raw power and track refinement earned the Camaro Z/28 MotorTrend’s coveted Best Driver’s Car award in 2014, a testament to its exceptional handling dynamics and driver engagement. Tragically, Chevrolet opted not to resurrect the Z/28 nameplate for the sixth-generation Camaro, leaving this iteration as a sought-after collector’s item.
Chevrolet Camaro ZL1 (Sixth-Generation) — 650 HP
Within the annals of Chevrolet Camaro history, the ZL1 badge represents the pinnacle of performance. While the original 1969 COPO Camaro hinted at the nameplate’s potential, Chevrolet fully embraced the ZL1 moniker with the fifth and sixth-generation models, resulting in some of the most powerful Camaros ever produced.
The fifth-generation ZL1 introduced the automotive world to a supercharged 6.2-liter LSA V8 engine, generating an impressive 580 horsepower. However, Chevrolet’s engineers were undeterred in their pursuit of greater performance. In 2017, they unveiled the sixth-generation Camaro ZL1, equipped with a supercharged 6.2-liter LT4 V8—a powerplant derived from the Corvette Z06 and an evolution of the already potent LT1 engine found in the SS models. This new engine produced a formidable 650 horsepower and 650 lb-ft of torque.
Performance claims for the sixth-gen ZL1 were staggering: a 0-to-60 mph time of 3.5 seconds and a quarter-mile elapsed time of 11.4 seconds, crossing the finish line at a blistering 127 mph. But the ZL1 was far from a one-trick pony. Its sophisticated engineering included a Magnetic Ride suspension for adaptive damping, Goodyear Eagle F1 Supercar tires for optimal grip, an electronic limited-slip differential for enhanced traction, and high-performance Brembo brakes for authoritative stopping power. These attributes earned the ZL1 widespread acclaim from contemporary reviewers, who favorably compared it to high-end European sports cars from brands like BMW and Mercedes-Benz.
