Jaguar Land Rover's Range Rover Sport will be the automaker's first plug-in hybrid.
The P400e version of the luxury SUV goes on sale immediately, kick-starting JLR's electrification push.
The company said last month it plans to offer a hybrid or full-electric version of every new model launched starting in 2020.
The plug-in hybrid Range Rover Sport combines a 300-hp 2.0-liter turbocharged gasoline engine with a 114-hp electric motor. A 13.1 kWh lithium ion battery is positioned under the floor of the trunk and can be charged in 45 minutes using a 32-amp wallbox-style charger or seven and a half hours with a standard household plug.
The car can travel 50 km (31 miles) on electric power alone and emits 64 grams of carbon dioxide per kilometer, according the European NEDC rating.
The car's default mode combines gasoline and electric driving, but it can switch to EV mode to drive on electricity only.
The SUV's starting price in its UK home market is 70,800 pounds ($94,000), which is nearly 8,000 pounds more expensive than the non-electrified version with the same gasoline engine.
U.S. sales for the P400e start in next summer, with prices starting at $78,300.
Rivals for the new car with similar plug-in hybrid technology include the BMW X5, Volvo XC90, Porsche Cayenne and Mercedes GLE. The Audi Q7 e-tron plug-in hybrid differs from the rest in using a diesel rather than a gasoline engine.
Car buyers in western Europe bought 84,168 plug-in hybrids during the first eight months of 2016, according to Swedish analyst firm AID. The top three sellers among the new Range Rover Sport's rivals during the time period were the plug-in hybrid versions of the XC90 (3,856 units), BMW X5 (2,922) and Q7 (1,709).
In the UK, which is the largest European market for plug-in hybrids with 18,512 units through eight months, the best-seller is the Mitsubishi Outlander PHEV.
The plug-in version of the Range Rover Sport is one of a series of updates for the model, which was first launched in 2013.
The car has a redesigned grille complete with hidden charge flap for the plug-in version. Inside, the infotainment system is upgraded to the latest version of JLR’s InTouch Pro Duo system with a 12-inch screen, which the company says is more intuitive and engaging to use.
Another update includes the Active Key wristband that first debuted on the Jaguar F-Pace. This allows owners to lock the standard key in the car if they are worried it will get wet or damaged during outdoor activities.
