Volvo Car Group on May 13 began production of its new four-cylinder engine family that includes gasoline and diesel variants on a platform known as the Volvo Environmental Architecture (VEA). The company invested about 2 billion kronor (about U.S. $303.7 million) to expand its plant in Skövde by 4500 m² (48,000 ft²) for the new engine line, preparations for which began two years ago. The company said in a press release that "the strategy of four-cylinder petrol and diesel engines and driveline electrification is the path that Volvo Cars has chosen for the future. With total control over the development and production of engines and drivelines and by reducing the number of engine variants, the result is increased flexibility and greater ability to influence quality." The new VEA family, developed in-house and to include three-cylinder variants, is optimized to deliver better performance than the incumbent five- and six-cylinder units while offering lower fuel consumption than Volvo's current generation four-cylinder units. Together with driveline electrification, VEA replaces the previous eight engine architectures on three different platforms. The new engines will be introduced between 2013 and 2015. Almost 20,000 engines will be produced in 2013, and by the end of the year the production rate will be 2000 units per week. The first VEA engines will be fitted to the Volvo S60, V60, XC60, V70, XC70, and S80 in autumn 2013.
