Mitsubishi said the next Outlander hybrid will have a more powerful electric motor and larger battery capacity — delivering more robust road performance.
It will also have an electric driving range that is higher than the current vehicle's 24-mile EPA rating.
The packaging of the new platform allows for third-row seating, giving the hybrid the same seven-passenger capacity as the nonhybrid, Mitsubishi said.
The Outlander and Nissan Rogue now share the same platform, but it's unclear whether the Rogue will also add a plug-in-hybrid variant. The two models also share the same powertrain.
Other companies have added plug-in hybrid crossovers recently, notably the Toyota RAV4 and Ford Escape.
The fourth-generation Outlander went on sale in April, with second-quarter U.S. sales rising 130 percent.
Mitsubishi aims to reduce carbon dioxide emissions from its new vehicles by 40 percent by 2030 through electrification, with plug-in hybrids as the centerpiece of the strategy.
