Chrysler PowerTech engine

The Chrysler PowerTech engines are a family of 90 degree single overhead camshaft V8 and V6 petrol engines that Chrysler built at the Mack Avenue Engine Complex in Detroit from 1999 until April 2013. The design began at American Motors and debuted under the Chrysler name, as the first new V8 for the company since the 1960s. A 4.7 litre V8 came first, in the 1999 Jeep Grand Cherokee, and a 3.7 litre V6 followed in 2002 for the Jeep Liberty. The engines had nothing in common with the older Chrysler LA V8 or with the Jeep 4.0 litre six, replaced the Magnum series, and were reserved for trucks and sport utility vehicles such as the Dodge Ram, Dakota and Durango. E85 compatible versions were built. The last 4.7 litre engine was assembled on 9 April 2013, ending 15 years and more than three million units.
