Fuel consumption is determined in accordance with standardised test procedures (93/116/EU). It is by no means identical with the car's average consumption, which depends on a variety of factors such as driving style, load, road condition, traffic density and flow, the weather, tyre pressures etc. Engine power output and the car's performance are measured in accordance with condiions laid down in 80/1269/EU and DIN 70020 (with the car to standard specification). This standard also specifies the permitted tolerances. Additional equipment (optional extras) can have a significant effect on performance and consumption, since it usually increases the car's weight and causes the aerodynamic drag coefficient ( c ) to deteriorate (for instance roof racks, wider tyres, additional mirrors etc.).
