You are right in the thinking of using less gas and that's exactly what the purpose was to have the start/stop feature. The main goal of doing it (at least here in the States) is for zero fuel consumption/zero emissions while the engine is stopped. This provides for better overall fuel consumption numbers to meet what the EPA has mandated for companies to stay in compliance with regulations. Considering what the government mandates, zero RPM will always produce zero emissions and have less fuel consumption than will 100RPM ... it all adds up. WRT the start/stop causing wear/tear on the starter/battery which would otherwise not be there, you are accurate in thinking so. The manufacturer can do two things to help mitigate this that I can think of (whether they do them is another story): They can design in a more robust starting/battery system in the vehicle. They can (and do) engineer the engine so it stops just short of firing a cylinder. When the engine goes to start again, it fires th
