My wife is looking to buy a car. We have test driven an A3 1.4 COD Stronic. The stop/start was very smooth. Engine restarts were almost instant and hardly noticeable. We are also looking at a Golf 1.6 TDI DSG. Every time the engine restarted it sounded just the same as an ordinary car starting. Not smooth at all. Is stop/start better in a petrol? Has anyone tested an A3 1.6 TDI Stronic? What is stop/start like in an A3 2.0 TDI Stronic? Yes, I know stop/start can be disabled, but this has to be done every journey.
