Starting sometime next year the engine and transmission will be built in Nissan's Smyrna, Tenn., plant.

The company recently shifted much of its production from cars to trucks in its Smyrna, Tenn., assembly plant.

Up to 40,000 per year will be built at Nissan's Smyrna plant.

The Smyrna plant is expected to produce up to 150,000 vehicles and 200,000 battery packs annually.

The Smyrna plant began producing lithium-ion cells in December 2012.

The workmanship, typical of the Smyrna plant, is first-rate; every button and hinge seems likely to last.

The increase reflected Nissan's decision last fall to shift production capacity at its Smyrna, Tenn., plant from cars to trucks.

The Smyrna plant is to continue building the Sentra car and a light pickup truck at current production levels.

Nissan's Smyrna plant is not unionized.

The Smyrna plant produced 220,000 vehicles in 1987, or about 83 percent of its 265,000-unit capacity.
