Chrysler says it is considering investing up to $198 million in its Mack Engine Plant in Detroit to increase output of its 3.6L Pentastar V-6 powertrain.

The auto maker earlier announced it would be idling production of its 3.7L V-6 engine at Mack Engine and attempt to reassign more than 200 factory workers affected by that change.

The potential investment would bring up to 250 jobs, Chrysler says. The auto maker says it is seeking incentives from the State of Michigan and the City of Detroit to proceed.

Production of the 3.7L V-6 ends in August. Chrysler says it has produced about 2.9 million units during that engine’s lifetime.

The 3.6L Pentastar, which Chrysler says eventually will replace four V-6 engines in its lineup, is a 2012 Ward’s 10 Best Engines winner.
