Volvo Cars has a long reputation as a maker of inline (or straight) engines. This list of Volvo engines gives an overview of available internal combustion engines. When Volvo started in 1927, they ordered their engines from the engine manufacturer Penta in Skövde. The first engine was the inline four-cylinder side-valve 28 horsepower (21 kW; 28 PS) Type DA. In 1931, Volvo acquired a majority of the Penta stock, and in 1935, Penta became a subsidiary of Volvo. For the engines used by Volvo Trucks, see List of Volvo Trucks engines.
