The Global Medium Engine (GME for short) is a family of engines created by a joint venture between the powertrain divisions of Alfa Romeo, Chrysler, Dodge, and Jeep of Fiat Chrysler Automobiles. It has been in production since 2016. The GME family is composed by two new series of engine: one created by Alfa Romeo (code project Giorgio) for Alfa Romeo Giulia and Stelvio, and the second (code project Hurricane4) by FCA US for American vehicles made by Chrysler, Dodge, and Jeep. Both are produced in Termoli, Italy at the Termoli Powertrain Plant. The first vehicle to use the GME T4 engine is the 2016 Alfa Romeo Giulia introduced in April 2016, followed by the Alfa Romeo Stelvio. The first American Hurricane was adopted by the new Jeep Wrangler (JL) in 2018 followed by the facelift 2019 Jeep Cherokee (KL) and the Chinese Jeep Grand Commander. It is currently available only in 2.0L capacities, with different tunings. The 2.0L GME-T4 received an update in 2025 dubbed Hurricane 4 EVO and is expected to debut in the 2026 Jeep Grand Cherokee WL mid-cycle refresh. This variant of the engine uses the Miller combustion cycle and will ultimately replace the Pentastar V6 engine as the main corporate engine for Stellantis North America in compact and mid-size applications.
