Upcoming Chrysler, Dodge, Ram, and Jeep Powertrain: Engines and Transmissions
Four cylinder engines
With thanks to “FGA Cheerleader” for gathering specs and updating information.
We started talking about these new engines back in 2014; they ended up as the GME (Gasoline Medium Engine) series. The
Hurricane turbo four, officially called GME T4, is part of this new group. ...
GME and Hurricane (turbocharged 2.0) engines
Jointly developed by USA-based and Italy-based FCA groups, and borrowing from the World Gas Engine, Fiat Twin-Air, and Pentastar V6, the GME will replace all current 2.0 to 2.4 liter engines used by FCA worldwide.
The
Hurricane 2.0 shows up in the Jeep Wrangler, but not wearing that name; it’s hooked up to a mild-hybrid setup to stay responsive despite the Wrangler’s formidable weight.

“MJAB” wrote that Alfa Romeo may use an electric supercharger combined with a traditional turbocharger, for faster reaction times, in the predicted 350-horsepower Alfa Romeo GME engine.

What sources have told us about the Hurricane Four
The engine is part of the GME (Global Medium Engine) family; Alfa Romeo’s version is already out, and produces 276 horsepower using MultiAir and two turbochargers. It has a flat torque curve of 295 lb.-ft. of torque between 2,250 – 4,500 rpm, and the turbocharger gathers exhaust from pairs of cylinders in an alternating sequence.
Alfa Romeo’s Hurricane is very different from the Chrysler version — made in a different foundry, with a closed deck versus the Mopar’s use an open deck. Chrysler tested two-stage turbocharging (illustration on right) in a Department of Energy project. Insiders say that cost will replace this system with a single twin-scroll turbocharger, small but with a high rotation speed.
