Ever since the huge media spectacle at the G8 summit in Heiligendamm, climate change is on everyone’s lips. In the car industry, he is a bit longer a current issue. However, he also bears fruit only since the media on climate change and its potential readers became aware sind.Seither be made more climate protection measures. Thus, the federal government hopes to save by the year 2020 30 million tonnes of CO2 and set a CO2 limit for cars and a modification of the motor vehicle .Steuer is already completed. But the auto industry comes with ever newer environmentally friendly innovations. Ford has launched an advertising campaign in June for its bio-ethanol vehicles. For a short time since the Ford Ford Focus and Ford C-Max offers with bio-ethanol power, the combustion is nearly C02-neutral. Another alternative is the hybrid engines, which can completely do without gasoline, or fuel cells, which are still in development. Greenpeace has before at this year’s “Week of the Environment,” a Renault Twingo, as noted by the specially developed SMILE-principle(Small, Intelligent, Light, was built Efficient). The Twingo has only 3 liters per 100 km, and consumes only half as much CO2 as a conventional Renault Twingo. The SMILE principle, there are way since 1996. But as I said the media attention did not come on right now. The auto manufacturers are developing more and more her driving assistants, which will make it safe to drive, to coincide with them, but you can also save fuel and thus to achieve environmental protection. Such as the Active Cruise Control Active Cruise Control (ACC). This system determines the sufficient distance to the vehicle ahead, so that unnecessary braking and acceleration maneuvers can be avoided. Similarly, a cruise control can save fuel, because this unnecessary Beschleunigsarien and braking situations are avoided.
