Volvo is sharply increasing production of its V60 Plug-in Hybrid for the 2014 model year.

Volvo is ramping up production of its V60 Plug-in Hybrid after a successful first year of sales. The V60 Plug-in Hybrid is built alongside standard versions of the V60 at Volvo's production facility in Gothenburg, Sweden.

Volvo announced on Monday that it is planning a 4,000-6,000 unit production run of the V60 Plug-in Hybrid for the 2014 model year. Volvo adjusted volume for the 2014 model year after completely selling out of the 2013 V60 Plug-in Hybrid before the car even arrived in showrooms.

"The V60 Plug-in Hybrid is a unique car, a historic step, not only for Volvo Car Corporation but for the entire car industry. The first year's 1,000-car batch was sold out even before the car reached the showrooms and the order books for next year's cars are already filling up," Peter Mertens, Senior Vice President Research and Development at Volvo, said.

Touted as the "world's first diesel plug-in hybrid," the V60 Plug-in Hybrid uses a 2.4L diesel engine paired with an electric motor. Backed by an 11.2 kWh lithium-ion battery pack, the system combines to deliver 285 horsepower and 467 lb-ft. of torque, with power going to all four wheels. Volvo says the V60 Plug-in Hybrid boasts a total range of 746 miles - 31 of which can be covered on pure electric power.

The 2014 V60 Plug-in Hybrid will continue to be built alongside conventionally-powered versions of the V60 at Volvo's Torslanda plant in Gothenburg. The plug-in version of the wagon requires more than 300 additional parts, but the V60 Plug-in Hybrid has been fully integrated into Volvo's normal production flow.
