The LS7 engine, a race-bred V8 known for its durability and high-revving nature, was mated to a six-speed manual transmission, ensuring complete driver control. The suspension featured Multimatic Dynamic Suspensions Spool Valve dampers, providing adaptive damping that could adjust to track conditions in real-time.
The Z/28’s performance credentials are nothing short of stunning. MotorTrend clocked a 0-60 mph time of 4.0 seconds and a quarter-mile run of 12.3 seconds at 117.2 mph. These figures rivaled the most powerful straight-line performers of its day. Yet, where the Z/28 truly excelled was in its cornering abilities. The combination of extra-wide Pirelli PZero Trofeo R tires, massive Brembo carbon ceramic brakes, and an aggressive aero package generated immense grip and stopping power. The result was a car that could carry incredible speed through turns, inspiring confidence in even the most seasoned drivers.
The fifth-generation Camaro Z/28 earned MotorTrend’s Best Driver’s Car award in 2014, a testament to its balanced performance and driver-focused nature. It represented a return to the Z/28’s roots as a homologation special for road racing, proving that track capability could coexist with muscle car DNA.
