Summary

Over the past 3 years, Volkswagen has laid the foundation stone for the global success of small spark ignition engines with outstanding low-end torque and low consumption, in the form of the 1.4l 125kW TSI with its combination of twin turbocharging and direct injection. Now, with the 1.4l 90kW TSI engine that was launched last year, the company has achieved a superb breakthrough for TSI technology in the medium power range as well. Frugality and in-gear acceleration remain the success factors even given the tense issue of CO2 emissions, or indeed precisely because of it.
