The concept plug-in-hybrid is also based on the all-new Tucson platform and is equipped with a 1.7-liter diesel engine and a seven-speed dual-clutch transmission. The engine generates 113 hp (85 kW) and is accompanied by a 67 hp (50 kW) electric motor and a 10.7 kWh lithium-ion polymer battery, which delivers an all-electric range of more than 50 km (31 mi). Combined system output is a maximum of 180 hp (135 kW) with 474 N·m (350 lb-ft) of torque, with estimated CO 2 emissions of less than 48 g/km.[44]
