Hello to everybody on the forum. I have a question: The prius sold in EU is rated at: extra urban 3.8/ urban 4.0/combined 4.0 (L/100km with 17" wheels) .. so how is the average calculated? it shuld be 3.9 right? Exemple: Toyota IQ EU engine 1.0l 5MT: extra urban 3.9/ urban 4.9/combined 4.3 (L/100km) how? European Urban cycle=4km; Extra-urban cycle=7km So... (4km x 4.0l/100km + 7km x 3.8km)/11km=3.8727/100km... ?? For the IQ: (4x3.9 + 7x4.9)/11=4.536.. witch is close to 4.3 combined but not quite. Any thoughts on this?
