The fuel economy of the 2023 Camaro is dependent on the vehicle's engine capacity. For example, V8 and V6 engine versions of the Camaro won’t have as good fuel economy as the 2L turbo engines.
Another factor to consider is whether the car’s use is mainly in the city or on the highway. Highway driving will have better fuel economy than city driving, whereby the vehicle has to stop and start many times, leading to bad fuel economy.
