VW L1 Concept

German carmaker Volkswagen developed the L1 concept. Under the hood it hides a small TDI with minimal fuel consumption and maximum range. The 0.8-liter TDI is the smallest diesel engine intended for production applications ever built by Volkswagen. The TDI, E-motor and the 7-speed DSG are located at the rear and gathered forces to create the most fuel efficient road-legal car hybrid drive in the world. The fuel consumption indicates 1.38-liters / 100 km and the CO2 emissions reach 36 g/km. It is a completely redeveloped two-cylinder turbo-diesel with common rail direct injection. The TDI develops 27 PS and 100 Nm of torque. The new VW L1 concept has a Start / Stop system that, automatically shuts down the engine when the vehicle has stopped and restarts when the accelerator or E-pedal is pressed. The hybrid module has been integrated into the housing of the 7-speed DSG and it produces 14 PS with its electric motor and clutch. The E-motor is supplied with energy from a lithium-ion battery located at the front of the car. In normal operation the electric motor can support the TDI engine in conditions such as by electric load point shifting and in acceleration. In braking phases, the E-motor operates as a generator to charge the lithium-ion battery by recovering braking energy. The engine controller regulates all energy flow and drive management tasks taking into account the moment by moment demands for power made by the driver. The cooling system of the L1 also contributes to the high efficiency of the car. Its external water pump is controlled by engine management do that cooling is only activated while engine operating conditions require it. The thermal management also contributes to reduced fuel consumption. The model is equipped with ABS and ESP and it is capable of reaching a top speed of 160 km/h.
