In November 2010, General Motors began investing million at its engine operations plant in Flint, Michigan, to support increased production of the Ecotec 1.4 L engine that is used in the Chevrolet Cruze, the upcoming 2012 Chevrolet Sonic, and the variant used in the Chevrolet Volt. The Flint plant was expected to start production of 400 engines a day in early 2011, ramp up daily production to 800 engines in late 2011, and to increase its capacity to 1,200 a day by late 2012. In May 2011, General Motors decided to invest an additional at the Flint plant to further increase 1.4 L engine production capacity. In 2010, General Motors planned an initial production for calendar year 2011 of 10,000 Volts and 45,000 units for 2012, up from the 30,000 units initially announced. In May 2011, the carmaker again raised its production targets, as Volt and Ampera production capacity was increased to 16,000 units in 2011, including 3,500 units for exports and 2,500 demonstration units destined to U.S. dealerships, and the rest for U.S. sales. However, in November 2011 GM's sales chief announced that they would not meet its sales goal of 10,000 vehicles in 2011. Out of the 2012 production, General Motors expected to produce 10,000 Amperas for sale in Europe, 6,000 destined for Opel and 4,000 for Vauxhall in the UK. In addition, 2,000 Volts were available for the region. By early 2012 GM abandoned its sales target to deliver 45,000 Volts in the U.S and instead announced that production in 2012 would depend on demand. By March 2012 the Volt plant has a global production capacity of 60,000 vehicles per year. The Volt's battery cells are produced by LG Chem in South Korea and then shipped to the US, where the battery packs are assembled at a purpose-built facility in Brownstown Charter Township, Michigan, owned and operated by General Motors. Compact Power, the North American subsidiary of LG Chem, is building a battery plant in Holland, Michigan, to manufacture the advanced battery cells for the Volt and other carmakers, with capacity to produce enough cells for 50,000 to 200,000 battery packs per year. The million Holland plant was funded by 50% U.S. Department of Energy matching stimulus funds and is planned to open by mid-2012. The 2011 Chevrolet Volt was officially launched on November 30, 2010, at a ceremony at the Hamtramck plant, where the first production
