Last week, Fiat Chrysler announced plans, along with a $4.5 billion investment, to expand its lineup of plug-in hybrids, including plans to build two new plug-in hybrid Jeeps in the U.S., including the Grand Cherokee and new versions of the Jeep Wagoneer and Grand Wagoneer planned to roll out in 2020.

Last June, at an investors' meeting, late Fiat Chrysler CEO Sergio Marchionne announced that the company is working on a plug in version of the Italian-made Jeep Renegade.

Now the company has revealed plans to build another Jeep heading up the plug-in mountain, the Compass.

The pair will share a powertrain that develops a combined 240 horsepower from an electric motor and a 1.3-liter, 4-cylinder gas engine.

The company says they will have 31 miles of electric range. Since the cars were unveiled at the Geneva auto show earlier this week, that likely means the range was measured on the European WLTP. test cycle, which is more optimistic than EPA estimates would be.

Being Jeeps, they need an all-wheel-drive system, and like most all-wheel drive plug-in hybrids, they'll use a separate electric motor on the rear axle to provide it.

Emissions are expected to be 47 percent lower than stringent European requirements.

Jeep also announced with the debut of the new Wrangler in 2017 that the most iconic Jeep will also be offered as a plug in hybrid, which was expected later in 2019.

At the June meeting the company promised an entire electrified Jeep lineup by 2022. With Wrangler, the Grand Cherokee, the Wagoneer, and Grand Wagoneer scheduled to debut as plug-in hybrids in the U.S., and now the Renegade and Compass in Europe, all by 2020, and the electric Grand Commander in China, the brand is making good on its promise early. The only holdout so far is the smaller Cherokee sold in the U.S.
