W203 Gas Mileage?

The Best of Mercedes & AMG
Only put it in C mode if I'm in an a downtown like area where I want to hear the engine a bit more and get a slower start.
Not sure if C will get better gas millage and put me to 22 for a long trip. Best I've seen is 21 when going from San Diego to San Jose.
Personally I think its all in how aggressive you are on the throttle.. some people in a VW TDI I think just set a record for most miles per tank. I'm sure how you accelerate and how fast you go are what really matter for your MPG's. Don't slam on it (like me) and don't go 80 on the fwy ( again like me).
So don't be like me and you'll get good MPG's. =)

This site is actually pretty spot on and shows I get about 20.. which is right. Put in premium and you may get up to 24. Also like others said. Check your tires make sure they are inflated to the right pressure. But for a 4matic I think you're about right.
I even had some fun with it going 90 + on the way home. I usually go 75-80 with the cruise on. I just use regular gas and my tires are at 40 lbs. (around there). c-ya

It will depend some on driving style, but you should get better gas mileage with the car in 'S' than 'W' or 'C'. 'S' mode will let you coast to the stop signs or while driving without trying to slow the car down. 'W' or 'C' mode tries to grab the car and slow it down, such as not rolling backwards down a hill (vs. 'S' mode lets you roll on down...). Using more gears HELPS with economy, it doesn't hurt it - will help the car stay more in it's 'efficient region' vs. having to mash the gas to get it to go. Remember all the gas saving commercials when the 7-speed tranny came out - the guy catching the drop of gas and putting it back in the tank?
I have checked this on numerous occasions, and I get a couple miles/gallon better when driving around town in 'S' vs. 'W'. I can do almost double that if I think about how far I can really coast before a stop sign/light without pissing other traffic off ('S' vs. 'W').
