Two electrified concepts, the Hyundai Tucson 48V Hybrid and Hyundai Tucson diesel plug-in hybrid, were displayed at the Korean company’s 2015 Geneva motor show stand.

The Hyundai Tuscon 48V Hybrid concept (above and below) features a mild-hybrid drivetrain consisting of a 100kW 2.0-litre turbo-diesel four-cylinder engine and a six-speed manual transmission.

A small 10kW electric motor, dubbed the hybrid starter generator, replaces the regular starter motor and is connected to a 48V lithium-ion battery. The electric motor is able to restart the diesel engine, as well as provide a small power boost as needed and recharge the car’s battery via regenerative braking.

Working in tandem, the drivetrain’s two engines are said to deliver a total of 110kW of power and 413Nm of torque. Fuel economy is said to be improved by 10 percent to 4.1L/100km, while weight is only 20kg more than a production Tucson featuring just the 2.0-litre turbo-diesel.

Also revealed in Geneva was a plug-in hybrid version of the next-generation Hyundai Tucson. The drivetrain of this car utilises a 85kW 1.7-litre turbo-diesel and a seven-speed dual-clutch transmission for the front axle — both of these components are employed in the Euro-market version of the new Tucson.

Power for the rear wheels is provided by a 50kW electric motor, which is fed by a 10.7kWh lithium-ion polymer battery. Depending on the driving mode, the plug-in Tucson can shift automatically or manually between front-, rear- and all-wheel drive.

Maximum power output from the Tucson’s diesel-electric drivetrain is 135kW of power and 474Nm of torque.

In all-electric mode, this Tucson can manage 50km of driving on fully charged battery. Hyundai believes that this car, if it made it into production, would return official fuel economy figures of 1.8L/100km or lower.
