Changan CS75 is equipped with the Blue Whale engine. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, which then expands the gas and pushes the piston to perform work. Taking the 2021 Changan CS75 as an example, its body structure is a 5-door, 5-seat SUV with dimensions of 4650mm in length, 1850mm in width, 1715mm in height, and a wheelbase of 2700mm. The fuel tank capacity is 58 liters. The 2021 Changan CS75 features a front MacPherson independent suspension and a rear multi-link independent suspension. It is powered by a 1.5T turbocharged engine with a maximum horsepower of 178 PS, a maximum power of 131 kW, and a maximum torque of 265 Nm, paired with a 6-speed manual transmission.

The Changan CS75 currently mainly uses the Blue Whale 1.5T turbocharged engine, model JL476ZQCP, with a displacement of 1.5 liters, delivering a maximum power of 178 horsepower and a peak torque of 265 Nm, paired with a 7-speed wet dual-clutch transmission. It employs direct fuel injection and advanced turbo technology, offering high fuel efficiency, with an official fuel consumption of around 7 liters per 100 km.
