At the international motor symposium in Vienna, Volkswagen presented three new powerplants: a 48-volt hybrid system, a natural gas turbo engine and a hybrid two-liter diesel engine. With their help, by 2020 the German manufacturer intends to reduce the average level of harmful emissions in the model range to 95 grams per kilometer.
The main novelty was a moderate hybrid system with a starter-generator, powered by a 48-volt battery. It provides additional power during acceleration and is capable of completely shutting down the engine when coasting, which saves up to 0.3 liters of fuel per 100 kilometers of track. The first “soft” hybrid installation will receive the Golf of the eighth generation.
The 1.5 TGI Evo engine, powered by natural gas or its synthetic analogue e-gas, is equipped with direct injection and a turbocharger with variable impeller geometry. The power of the unit is 130 horsepower and 200 Nm of torque. The consumption of such an engine on the Golf of the current generation is 3.5 kilograms of gas per 100 kilometers. The power reserve is 490 kilometers.
The structure of the diesel-electric power plant with the EA288 Evo index included a two-liter engine, a 12-volt starter generator with belt drive and a block of lithium-ion batteries. The total output of the system is from 136 to 204 horsepower. At first it will only be for Audi models.
