Dekra is the agency responsible for carrying out the equivalent to our ITV in Germany, but his work is not limited to reviewing vehicles. From the data obtained in these reviews, develop a comprehensive reliability ranking.
They use the so-called DFI (Dekra falut Index, or failure rate of Dekra), which compares the faults present in a vehicle with the average segment. Thus get some backed by a wealth of information results obtained from none other than 15 million analyzes in more than 500 models. For added reliability, do not give statistical significance to a model if it has been reviewed at least 1,000 times.
Inspections carried out are listed in three intervals of mileage: 0 to 50,000 km, 50,000 to 100,000 km and 100,000 to 150,000. And for the first time this year have created a section launched on the market in the last three years cars, in which only it takes into account the first interval mileage. There is also a classic car section, in which cars over 30 years are valued most popular, and one for regular cars in the used market which they have been discontinued.
Through this methodology, Dekra has concluded that the model with fewer defects is the Audi A6, in all three mileage intervals. The rest of the ranking, by segment, as detailed below:
