Petrol cars, of course, far from the platform for a greener operation (stress-it is in use, ecological production will leave behind the scenes). But cars with conventional internal combustion engines are becoming gradually more and more "friendly nature". One example is the Renault Clio Expression Eco. This model, with 89-horsepower diesel engine, when you install a so-called eco-package costing about $ 400 (the system "start-stop" aèrodinamičnye 15-inch wheels and tires with low rolling resistance tires) provides CO2 content in the exhaust gases of just 94 g per kilometre. Fuel consumption of just 3.6 liters per 100 km. Thus, in the fully charged tank car is able to run nearly 1500 km. Indeed, indicators of efficiency and ecology at Renault are close to those of competitors-Ford Fiesta Econetic and VW Polo BlueMotion TDI. However, the Frenchman is a lower price, which in Europe is about 20 thousand dollars.
