The new Volkswagen Jetta Stop/Start system

http://www.eurocarnews.com - Volkswagen AG - Stop/Start system: The driver approaches a red light, brakes the Jetta to a stop, shifts into neutral and takes the foot off the clutch (with DSG it is sufficient to press the brake pedal). This causes the engine to shut off momentarily. In the multifunction display the text "Start (A) Stop" appears. As soon as the traffic light turns green again, the driver depresses the clutch (or with DSG simply releases the brake), and the engine starts, the "Start (A) Stop" text is cleared, the driver engages a gear and resumes driving. Essentially, the driver does not need to perform any extra operating steps compared to a conventional car, yet saves up to 0.2 litres per 100 kilometres in the city using the Stop/Start system.
