Two separate sources, a union official and a company insider, have told Automotive News that Chrysler will soon present a smaller displacement version of its 3.6-liter Pentastar V6 gasoline engine.

Bruce Baumhower, president of UAW (United Auto Workers) Local 12 in Toledo, Ohio, where the Liberty replacement (called Cherokee in markets outside the U.S.) will be assembled, told the news site that the SUV would be offered with a new V6 with a capacity of 3.2-liters.

The union official added that the smaller Pentastar V6 would be linked to the Chrysler Group’s new nine-speed automatic transmission, developed by ZF.

Chrysler-Fiat CEO Sergio Marchionne has already confirmed that the new Liberty will receive its world premiere at the 2013 Detroit Motor Show.

While a Chrysler spokesman told the website that it doesn’t “discuss future product or production plans,” an unnamed source from within the company verified Baumhower’s claims.
