That's my first post, I own an SLK200 R-171 and since new (8800km now) the computer shows 8.7 liters / 100km (about 11.5 km/l)
I've to say I am not using the car downtown, I live just about 20km from a major city and most of the times I use the car to go to the airport or to reach some cliffs where I go climbing, therefore the traffic doesn't bother me 80% of the times.
Actually I thought I would have had a better fuel consumption, since the SLK200 is not a real sport car, with a 1.8l engine and just 163hp. I got rid of a Boxster S, whose fuel consumption was around 7km per liter, but that was understandable on a 3.2l engine with 100hp MORE than the SLK200...
I heard the SLK200 restyling is less thirsty than my pre-restyling R-171, anybody here have had the chance to compare the two cars?
For city driving i get between 4.5-5 miles/litre. On highways it gets to 6 easily if the journeys are long. On a trip from Yorkshire to London and back i got 6.5 per litre but the journey was over 500 miles and steady driving with no passenger and nearly no luggage.
I rarely get a mixed consumption under 10 l/100km. If I really try to drive calmly I get it to about 9, but that don't impress the ladies...
Of course, on the Autobahn, I don't dare to even look
At first the consumptioned bothered me as well, but then I thought about it. After all it's about sound and feeling and g-force, not about economic driving and hugging trees. To quote SLK Rabbit: "Prius, hmm I think I'll drive the SLK " Now, I just give the car all the juice it want's, in large chunks...
I do have to say I use fuel whit octane 98 (from total fina). And I average a 8l/100km around town and I just did a drive of 120km which was High way and city mix whit drive up and down hill, right and twisting road. so a lil bit of everything and evenly balancet. And I got a average of 6.9l/100km. but moste of the time my consumtion is around 8 because I like to flor it at the red light. Don't forget every time you start the consumption go's up. If you fil here up and would start driving whitout stopping till you fuel tank is empty you schoulde easy drive more than 1100km.
