Sanırım otomobil kullanıcıları arasında en sık tartışılan konu tüketim mevzusudur. Herkesin güzergahı, trafik durumu, sürüş stili vb. unsurlar değişken olduğu için tüketim hesaplamasında uluslararası ölçütler koymak gereklidir. Bu ölçütler bizi araç alırken her daim baktığımız katalog verilerine götürür. Peki bu katalog değerleri nasıl hesaplanıyor. Açıklaması aşağıda:
"Urban cycle
The urban test cycle is carried out in a laboratory at an ambient temperature of 20°C to 30°C on a rolling road from a cold start where the engine has not run for several hours. The cycle consists of a series of accelerations, steady speeds, decelerations and idling. Maximum speed is 31 mph (50 km/h), average speed 12 mph (19 km/h) and the distance covered is 2.5 miles (4 km). The cycle is shown as Part One in the diagram below.
Extra-urban cycle
This cycle is conducted immediately following the urban cycle and consists of roughly half steady-speed driving and the remainder accelerations, decelerations, and some idling. Maximum speed is 75 mph (120 km/h), average speed is 39 mph (63 km/h) and the distance covered is 4.3 miles (7 km). The cycle is shown as Part Two in the diagram below.
Combined Fuel Consumption Figure
The combined figure presented is for the urban and the extra-urban cycle together. It is therefore an average of the two parts of the test, weighted by the distances covered in each part."
