Kia Optima Specs, Engines & Dimensions (2003–2005) — First Generation Restyling
The facelifted first-generation Kia Optima offers a traditional sedan layout. If you’re choosing a used example, start with its condition and service history, then consider which engine and transmission combination best suits your daily driving.
Among the Kia Optima engine options, the gasoline 1.8 MT and 1.8 AT let you choose between manual control and fewer demands in stop-start traffic. The 2.5 AT combines a larger gasoline engine with an automatic transmission. All three examples send power to the front wheels.
