Summary

Volkswagen is expanding its engine portfolio and thus rounding off the bottom end of its line-up of efficient downsized drives. The maximum flexibility of the EA211 engine range offers the best possible starting point for environmentally friendly CNG derivatives in all displacement classes. A new 1.0 l CNG engine with an output of 66 kW (90 hp) and 160 Nm of torque has been developed on the basis of the 3-cylinder TSI for use in the new MQB-A0 platform. Its first application will be in the new Polo TGI in 2017. The bivalent drive in the new Polo TGI offers customers the optimum combination of running on either CNG or petrol. The low fuel consumption (CO₂ emissions of 87 g/km NEDC) and the clean combustion of CNG enable environmentally friendly and cost-effective operation. However, if CNG should be unavailable, customers still have a fully-fledged, conventional TSI at their disposal. CNG represents an important element of Volkswagen’s engine strategy now and in the future and, in combination with electric drives, can reduce CO₂ emissions on a sustainable basis. Particular attention is afforded to the biogenic, renewable generation of the energy carrier.
