I have an excellent Volvo 480 but it is 15 years old, and I am thinking of buying under the "scrappage" scheme a new "Volvo C30 DRIVe". However, advertising from Volvo proclaims: “It also uses our brand new Start/Stop technology to cut CO2 emissions by up to 5% and fuel costs by as much as 8%. Here's how it works: when you put the car into neutral and release the clutch, the engine switches off-while maintaining comfort settings such as air-conditioning and the stereo system. Then, the next time you press the clutch, the car starts again." I can accept engine cut out at traffic lights, but I can't see a positive when I am in a line of slow moving, stop/start traffic. I am sure that Start/Stop technology in those circumstances would use more fuel, run down the battery and annoy me considerably. What would your thoughts be?
