Manufacturer’s specification test against the consumption of large consumption lie - Nissan Juke GTR

By Jan Kretzmann They also regularly fail to achieve in an attempt by the manufacturer promised average fuel consumption of your new car? For your honor rescue was told: It is not your driving skills. Rather, the consumption data, which lure car maker in its glossy brochures are far from any reality. This is demonstrated by the test scores of AUTO BILD. So, for example, according to the call/pubjumpi/10017/(themen/testberichte_story)/4459/M/[timestamp]/?” title=”"> VW Polo 1.2 TDI BlueMotion 87g Developer: with some startling results an average of 3.3 liters of diesel do. In the test, however, approved the Wolfsburg 4.8 liter – roughly 45 percent more usage than the factory specification. Even worse, the Audi A6 3.0 TDI multitronic. Rushed to the quoted 5.1 liters during the test drive, 7.8 liter fuel through the fuel injectors – almost 53 percent more than Audi promises. Your car uses too much? autobild.de shows up in the Gallery 100 vehicles in which the test consumption is at least 25 percent above the manufacturer’s instructions. As a basis for the list serve all of AUTO BILD vehicles tested from the years 2010 to 2012.

Overview: news and tests for all car brands

The main reason for the outrageous consumption differences: Car manufacturer calculate the consumption of the vehicles with a standardized measurement procedure on the dynamometer. This provides similar fuel economy – across manufacturers and national borders. With the reality of these values ​​but have little in common! tests AUTO BILD consumption: Each test car completed a test drive on a well-defined circuit. This is exactly 155 km long and consists of-town (40 kilometers), agriculture (61 kilometers), and sections of motorway (54 km). Driving is quickly but not sporty. Speed ​​limits are utilized, ie, in the city 50 km / h and on country 100 km / h run. On the highway is 20 km at full throttle, with the remaining 34 kilometers are a constant 120 km / h.. At the beginning and end of the measurement of each car is fueled to the brim. An exception in our survey, incidentally, is the Opel Ampera , 225 percent of consumption equal exceeded the manufacturer’s instructions. The explanation: The manufacturer specifies the consumption for the first 100 miles. Our test route but has 155 km of which unwinds the Ampera only about 40 with electrical supply. Thus, the Opel comes with us on an average consumption of 5.2 given in lieu of 1.6 liters.

thus measuring the manufacturer of its fuel consumption

.The standardized measuring process (Directive 80/1268/EEC and 101 ECE) of the manufacturer at a glance: completing Each car has a nearly 20-minute cycle on the dynamometer, including four city tours (each 195 seconds) and a cross-country cycle (400 seconds). The car sets well back eleven kilometers, reached an average speed of 33.6 km / h. Full throttle is off limits. The top speed of 50 km / h (city) is only twelve seconds, the 120 km / h. (extra urban), only ten seconds. Other criteria: Each vehicle must have at least 3000 miles on the odometer, the tank must be filled to 90 percent. The air temperature in the test chamber is between 20 and 30 degrees Celsius, atmospheric pressure and humidity are also prescribing them. After completion of the driving cycles to calculate the consumption of the examiners from the exhaust values ​​.*

Such high discrepancies between ECE standard and everyday consumption are not only annoying for the car buyer, but possibly also for the automaker. The Federal Court has already ruled in 1996 that an increased consumption of more than 13 percent is unacceptable for the specified use for the purchaser ( Az VIII ZR 52/96 ). The main reason the average of all three driving cycles (urban cycle, 90 km / h, 120 km / h). Thus measures the consumption of similar weight in the legislature, like other defects. Also, strong drafts, uncomfortable wind and engine noise can be remarkably annoying shortcomings that must not accept the buyer. If the defect is evidenced by an opinion, the customer can either reduce the purchase price or to convert the car – ie switch back to the dealerships and reclaim his money
