The SEAT Leon Ecomotive was a Leon that had been picked over and removed of many inefficiencies in order to deliver a frugal 3.7 liters/100 kilometers (63 miles-per-gallon) as well as lower CO2 emissions. The SEAT Twin Drive Leon Prototype takes that idea a giant leap further by making the car a plug-in hybrid, adding a 35kW electric engine to the car that handles all of the motivation on the urban cycle.
Almost all of the car's running gear was massaged in the drive to become a hybrid. A lithium-ion battery pack powers the electric motor, and it is said to propel the car to a range of 50 km and a maximum speed of 100 km (62 miles-per-hour). For the moment, the 1.9-liter TDI engine remains to handle extra-urban duties. However, SEAT is looking at completely phasing out the internal combustion engine on future Ecomotive models.
