Did you ever notice any influence of weather to the fuel-efficiency?

You might remember when direct injection was quite a rocket-science feature. Then, either resorting to a large-capacity intercooler (or water injection) or to enrich the air/fuel ratio was a requirement to prevent knock. Remember when Hyundai introduced the 1.0 turbo to the previous-generation HB20 retaining the port-injection and was plagued with excessive fuel consumption? No wonder it has turned to direct injection for the current generation, the same way it had been with any other overseas Kia or Hyundai with the 1.0 turbo engine before its introduction to Brazil.
