Hello dear Motortalker, I am looking for a second car to my A6 2.4l Avant. I will mostly use the car on the motorway at 130km/h on long distances. From time to time also faster, but rather rare. Combi is not necessary, but very good comfort to be still fit after 1000km in one day, as with my A6. A gasoline is more appropriate. Automatic is a must. 6 resp. 8 cylinders would be great, but consumption is more important. I would like a BMW, since I always thought, B MW represents the more efficient cars: E46/E39 or e38. Are of course not the same classes, but what is important to me is a travel car with a fuel consumption of up to 8-9liter at 130 on the highway. I suspect that an E46 is not so the long-haul machine and that the e38 does not come under 10l (738i maybe?) Does a 520 at 130 consume less than a 523 or 528? I made myself smart on spritmotor.de, but the consumption is also very dependent on the driving behaviour n. Are there some of us here who are travelling comfortably on the highway with E38 or e39 and have measured their consumption times? Who can give me one, please? Many greetings Ludwik
