Hello, who cares: the efficiency of the engine from IS 250 (2.5Ltr 6 Zyl., 208hp), in conjunction with the automatic, is m. E. exemplary! In 5 days of last week I cycled to Sweden and back 2,638 km, except for a few km only highways. After fuelling 472,9 Ltr Super were consumed: corresponds to 8,3Ltr/100km!!! A very good value, the consumption in the individual tank sections: 8,4-9,0-7,9-8,1-8,7!! Possibly doubtable, this was not a savings trip, for The distances are too large. Dangers were according to StVO, in case of lack of speed control 160-180 km/h. Regulation highway in Denmark: 130 km/h, Sweden 110 km/h. In case of performance, smooth running and economic efficiency, nothing remains with me. The above values are significantly better than with comparable German products. What more do you want? Greeting
