General Motors says its Flint Engine Operations will serve as the manufacturing site for the new Duramax 3.0L turbo-diesel for the 2019 Silverado.

In 2015, GM announced a US$263m investment in Flint Engine Operations for a new engine line.

The 2019 Silverado will be available with six engine/transmission combinations. One of these choices will be the new Flint-built 3.0L inline-six turbo-diesel.

The new turbo-diesel will be paired with a Hydra-Matic 10-speed automatic transmission and is expected to be an efficiency leader in the Silverado lineup.

"The next-generation Silverado builds on the success of our current models, many of which are produced here in Flint," said Flint Engine Operations plant manager, John Urbanic.

With diesel offerings on Equinox, Cruze, Colorado, Express, Silverado 1500 and Silverado HD, GM maintains no other brand offers more diesel models or diesels in more segments than Chevrolet.

Flint Engine currently produces 1.4L engines used in the Chevrolet Cruze, Equinox and Volt.
