It is said that 25% of fuel savings depend on the driver’s right foot, but one thing is for certain, when idling at a stop light or sitting in traffic, all cars get zero miles per gallon. That is why the German luxury car builder Mercedes Benz is planning on incorporating the fuel saving start/stop technology in their E200 CGI model by the middle of 2010. The E200 already has an economic four cylinder gas engine, but without wasting gas while standing still, the vehicle’s fuel efficiency is that much greater.
According to Christoph Spengel, head of engine development for Mercedes, the start/stop technology will be standard in every model. In a recent interview with AutoCar Spengel said: "I won’t name a year when we will achieve this goal, but it is a priority for Mercedes. We are pushing hard, and there is the possibility to jump ahead of BMW."
