C350's Recent Highway Mileage
 

My C350 took its first road trip in a while - from Denver to Western Kansas. I thought the computer's mileage might be off when it read 29.1mpg. To my surprise, averaging both fill ups, I calculated 28.7mpg. Not bad. By the trip computer, I averaged 28.6 on the return trip. Admittedly, I didn't push it too hard (would you be in a hurry to get to that destination? :)). It was about 90 degrees on both days and no wind.

That's pretty good. ;)
I average ~27-28 when going 250 miles back and forth from the lakehouse.
Did you take any pics of the C on the roadtrip?

Awsome, only problem I see is that you are in "comfort" mode LOL.

I have 2009 C350 on order:D
Is there a difference in gas mileage between "Comfort & "Sport" mode?
29.1 MPG is much better than what the sticker says and is great.

First road trip here as well and also 28-29mpg. This included 3 adults, a baby, full trunk of luggage, and air conditioning on the whole time.

Highway trips is where this car really shines. Up until this point I only did congested daily commutes.

I have a C300, so it's a different engine, different car, but on highway trips from the SF Bay Area to Los Angeles (just did another over the 7/4 weekend), I get around 28.1~28.5 MPG. I must say I'm pretty impressed, as I don't drive very slowly, and I had A/C on the entire way to and from the destination.

I just took a small trip to Santa Ines total round trip 232 mls I average 26.3 mpg driving 75 to 80 mph a/c on all the time and a lot of hills.

Too funny - good observation!
