Took my car for its first long run yesterday. Ok relatively speaking 53 miles isn't exactly long, but with an annual mileage of under 5k it's long for my cars. The journey is one I know well and is mainly motorway/duel carriageway with a short amount of urban at either end, and is approx. 106 miles round trip measured door to door. It was my first chance to see what the average fuel consumption is on my car over a longer distance, and the result surprised and impressed me. Ok I wasnt in a hurry and for the most part had cruise set to 58mph, but sometimes it's just nice to relax and watch all the other cars whizzing past....it's less stressful and you still arrive at your destination not far behind somebody who puts their foot down. Oh and I still had to overtake a few other cars even travelling at this low speed. Taking the above into account I think an almost 60mpg avearage is very good for a 224 PS engine, and it actually broke this barrier on the return journey. The return journey was in the dark and it was interesting to watch the Multibeam LED headlamps do their thing. Only downside of the journey was that I have not yet figured out my seating position that doesnt result in a pain in my lower back. Boofle ready for his road trip. He was previously loyal to Audi but he's really enjoying this new Mercedes.
