Are 95 grams per kilometre even feasible?

Bergisch Gladbach, 14 February 2017

The CO2 emissions of passenger cars in Germany to sink, but slowly. So slowly that it is unclear whether all car manufacturers can reach the aspired target of 95 grams per kilometre 2021 in the year. A new study of the "car"Professor Stefan Bratzel of the center of automotive management (CAM).

SUVs consume more than comparable cars

According to investigation the CO2 emissions of the German cars from 2011 to 2016 dropped significantly: from about 146 to about 127 grams. But while the values declined annually in recent years to around three percent, it was only 1.1 percent in 2016. As a reason for the slowdown Bangara indicates the increase in the number of SUVs and the declining rate of diesel. The market share of SUVs rose according to study since 2007 from seven to 21 percent, and SUVs have higher CO2 emissions than comparable cars. There, Bangara is right: A VW Tiguan 2.0 TDI with 150 Horsepower and four-wheel drive emitted according to the data sheet 146 g / km, an equal to motorized Passat variant only 123 grams. Also, the diesel rate in Germany fell in the year 2016 by 48% to 45.9%. Even in the diesel land France, the ratio declined sharply from 57 to 51 percent.

Peugeot top, Porsche flop

The individual manufacturers cut very different balance of CO2. Renault/Dacia, Toyota/Lexus, and particularly Peugeot are best when the volume manufacturers, also VW is still above average. Bad marks get, however, Fiat, KIA, Hyundai and Ford and Opel. High CO2 levels by Fiat (138 g / km) are concluded, inter alia through the Ducato. Since badly truncates also Jeep (177 grams), Bangara feared that the FCA group missed the limit of 95 grams if the efforts are not stepped up. During the season, Volvo reached the best value with 127 grams. BMW/mini achieved rounded the same value, followed by Mercedes/smart (132 grams) and Audi (133 grams). Jaguar cut its emissions significantly, but with 149 grams is still far above the numbers of the competition. The latter applies also to Land Rover. Porsche is even worse with 194 grams, but because the values are offset with the other brands of the VW Group, which is not so bad for the sports car manufacturer.

Has its zenith already crossed the diesel?

Total sobering CO2 balance is also attributable 'lack of acceptance and technological maturity of Electromobility' according to Bangara. And the diesel especially when private individuals has been discredited by the scandal of diesel. Because petrol engines emit more CO2 to 15 to 20 percent, which leads to higher emissions. The authorities also eye the diesel now with suspicion. Appropriate flue gas cleaning but also stringent NOx limits can comply with the diesel, so the car Professor. But this, increase the acquisition cost according to Bangara to around 500 to 800 euros, making the diesel in particular at small cars less attractive. The new exhaust gas tests (meaning the RDE measurements in normal road traffic are probably) and are likely to continue more stringent NOx limits the diesel will make it hard. So Bangara believes: "The high point of the diesel motors as drive technology seems already passed on a global scale." (sl)
