British SUV manufacturer Land Rover may be late to the hybrid party, but they are making up for it as they prepare to unveil their first plug-in hybrid (PHEV) models. At the moment, they do offer conventional hybrids in the form of the Range Rover Hybrid and Range Rover Sport but with Jaguar-Land Rover's (JLR) commitment towards electric vehicles, Land Rover is keen to expand their alternative power vehicle range.

Speaking to Autocar UK, JLR CEO Ralph Speth that the PHEV versions of the Range Rover and Range Rover Sport will be launched within the year. Spy shots from our sources appear to confirm Speth's target date of launch. In their batch of photos, the plug-in Range Rover Sport showed slight cosmetic alterations, namely to the bumpers, headlights, tail lights and trimmings.

Exterior changes may be minor but it's the powertrain that sees a revolution within the luxury marque. There are two likely powertrains to power the Range Rover PHEV and Range Rover Sport PHEV. Autocar UK reports that the internal combustion engine is poised to be the 2.0-liter, four-cylinder turbocharged mill with 300 PS and 400 Nm of torque. The electric motor meanwhile packs 201 PS and 450 Nm of torque.

However, given that the hybridized Range Rover and Range Rover Sport use a V6 turbodiesel, the electric motor may be paired to that particular engine as well. Dubbed the TDV6, it produces 258 PS and 600 Nm of torque. If Land Rover decides to pair it with the diesel instead of the turbocharged gas engine, we might just see world's first plug-in hybrid diesel vehicle to hit the market.
