The racing-proven LS7 7.0L V-8 powers the all-new 2014 Camaro Z/28 – the most track-focused production model in the car’s history. It’s matched with a TREMEC TR6060 six-speed manual transmission with unique gearing tailored to the LS7’s performance characteristics for optimal track performance.
The Z/28 engine is adapted from the LS7 used in the C6 Corvette Z06, which was developed in conjunction with Corvette Racing. It is rated at an estimated 500 horsepower (373 kW) and 470 lb.-ft. of torque (637 Nm) in the new Camaro Z/28, with a maximum engine speed of 7,100 rpm – a broad rpm range that contributes to higher power and allows the driver to hold gears longer between shifts on the track. That helps keep the engine at peak power for quicker lap times.
“The LS7 lives on in the all-new Z/28, extending a performance legacy while delivering great power density in a lightweight package to give this exciting new Camaro a great feeling of control and balance,” said John Rydzewski, assistant chief engineer for small-block engines. “It introduced exotic materials and racing-influenced solutions that keep it at the forefront of high-performance technology.”
