The replacement for the aging Jeep Liberty is expected to debut at next January’s Detroit Auto Show, and when it does, a brand-new Pentastar powertrain will reportedly be spinning underhood. According to Automotive News, Chrysler will offer a downsized 3.2-liter V6 in the Liberty mated to a nine-speed automatic transmission sourced from ZF. The current Pentastar V6 displaces 3.6 liters and has been well-received by both critics and buyers in everything from the refreshed Dodge Journey to new Chrysler 300. Funk Flex
