The initial design development for the PowerTech V6 and V8 engine family was done by American Motors Corporation (AMC) and debuted in 1998 with credit to Chrysler. This was the first new V8 engine for Chrysler since the 1960s. The companion V6 was basically the V8 with two fewer cylinders, another concept that originated at AMC before the company joined Chrysler. These new engines had nothing in common with the Chrysler LA engine V8s, nor the Jeep 4.0 L "PowerTech" I6 engine. A 4.7 L V8 came first, available in the Jeep Grand Cherokee, and a 3.7 L V6 version debuted in 2002 for the Jeep Liberty. The PowerTech V6 and V8 were direct replacements for Chrysler's Magnum series in the early 2000s, and were also used in the Dodge Ram and started in the 2000 Dodge Durango. They were not used in any cars, but were reserved for truck and SUV use. They are also known as Next Generation Magnum in Dodge applications. The PowerTech V6 and V8 engines were produced at the Mack Avenue Engine Complex in Detroit, Michigan. E85 compatible versions of some PowerTech engines were developed and used in numerous Chrysler vehicles. On April 9, 2013, the last 4.7 L engine was built; ending 15 years of production with over 3 million units built.
