Mercedes C250 4MATIC Slow and Sluggish
Hi forum members. I recently purchased a pre-owned C250 4MATIC with the V6 engine. I enjoy driving the car and everything but I feel like the car is so slow and underpowered. I realized that there is the C300 and C350 but I just want to know if 0-100 KMH (0-60MPH) is too high for my car. I timed it and it was just below 11 seconds. Overall this car feels really slow. What can I do to increase the power of my car. ECU tune or something of that nature?

Whats the overall condition of the car mechanically? Mileage? When was the last time the air intake filters were replaced?
Look up how to clean your MAF sensor. My C250 felt sluggish and shifted poorly in comparison to my father's (same model, lower mileage) until I cleaned the MAF fully. This seemed to restore some feeling of power, but mostly made it shift much more smoothly. Also, be sure you're running 91 octane fuel, perhaps run a bottle of techron through the tank (ONLY techron. other fuel additives aren't approved) as well. The only other thing that I think you could try is to reset the TCU, look that up on these forums.
Typically I see 0-60 time within 8.5-9.2 seconds. It isn't a very fast car, but it handles nicely.
ps. Use S mode, C feels sluggish as hell.

The condition of the car is actually great. Only has 30,000 miles on it currently. I always drive in S and always run 91 Octane fuel with no Ethanol. I will look into cleaning my MAF sensor and perhaps replacing my air filters as I don't know when they were last replaced. Will update. It isn't fast but just disappointing that 0-100 is 11 seconds. Love the car great handling
