Hey folks, looking at a C300 or C350 in RWD or 4matic, could anyone post what they typically get for gas consumption ( combined )? - in litres per 100 kms. Thanks!

(but you can see relatively small differences in mileage)

Fuel consumption 2.5 City: 11.8 L/100 km (24 mpg Imp)
Hwy: 7.4 L/100 km (38 mpg Imp)
Fuel consumption 2.5 4MATIC City: 11.9 L/100 km (24 mpg Imp)
Hwy: 7.9 L/100 km (36 mpg Imp)

Fuel consumption 3.0 City: 11.7 L/100 km (24 mpg Imp)
Hwy: 7.7 L/100 km (37 mpg Imp)
Fuel consumption 3.0 4MATIC City: 12.0 L/100 km (24 mpg Imp)
Hwy: 8.0 L/100 km (35 mpg Imp)

Fuel consumption 3.5 City: 12.2 L/100 km (23 mpg Imp)
Hwy: 7.9 L/100 km (36 mpg Imp)
Fuel consumption 3.5 4MATIC City: 12.5 L/100 km (23 mpg Imp)

I had a brand new loaner 300 for a couple of days and wasn't really impressed at the mileage - 22 displayed average over a 90mile commute. I posted my impressions at http://www.benzworld.org/forums/w204-c-class/1375552-my-impressions-new-08-c300.html?highlight=speedometer

I hope when properly broken in, these cars do a lot better! Right now I don't care much about other data, but compared with my wifes 03 320i, the 08 C's 22-24 average MPG is really really really bad!!! The old Bimmer easily gets 28-30. In town the 300 was in the 17mpg range, just a tad better than my 05 ML500!

Our car is a C300 Lux, which means the std USA 17" non-staggered wheels/tires.

At 10 months and 8300 miles, we generally get 20-21 mpg in suburban grocery-getting mode [12-20 miles round-trip, some surface, some freeway], and 27-30 mpg on long trips with pure freeway driving.

A recent leg from Central Calif back to Portland [Vancouver WA] was 500 miles, with 28 mpg and the AC running full blast the whole way. [This involves gaining and losing 4500 feet of altitude along the way, average speeds 70-75 mph, dry roads.]

Because of the more relaxed differential gearing, the C350 rwd car won't vary that much from these kinds of numbers. Deduct 1-2 mpg for AWD cars.

Translation: the 2008 EPA figures are not that far off; you can do a bit better, esp on the highway, but the numbers on the sticker are pretty close.

I've got a C300 with the 18" whiles, rear drive. I've noticed an overall combined average of 22mpg. Could be better. I can get an average of 27-29mpg if i take it easy on the gas pedal and maintain an RPM of 2100rpm or below.

Just turned over 10,000 km om my C300 4matic since it was delivered in late November. Avg consumption is sitting at 10.8 litres per 100 km for 70% city mileage / 30% highway. Typical daily commute from Misissauga to downtown Toronto averages 10.2. Best I have seen is around 8 l/100 km on a drive to Ottawa. Mileage is improving with warmer weather and engine getting broken in.

My C300 can go up to 480km until the "fill up signal" (not the reserve gas warning) comes up. And I fill up 58L. Mostly drive on hwy...

C300 averaged 21mpg over last 2800 miles of mixed driving, which is in-line with US EPA gas mileage ratings.

My normal driving week (mix of town/highway), I average about 22. On strait highway runs, I average between 27.5 and 28.5 depending if I am doing 75 or 80.

My car is RWD with the 18in AMG's.

I have 12k miles on the car as of this morning and according to the computer, I have average 22mpg for those 12k miles. I wish it was a little better around town, but I am not complaining.

I don't blame the OP for not relying on EPA estimates or whatever the sticker says. My car (C300 Sport) gets me 28 highway (8.4 l/100 km) going 65 mph (104 km/h) or 26 mpg (9.0 l/100 km) going 75 mph (120 km/h). City, I get roughly 24 mpg (9.8 l/100 km) and that is going VERY easy on the gas.

My Audi A4 1.8T showed 22/29 (10.7/8) but I was consistently able to get 36 (6.5). My Isuzu Trooper showed 15/19 (15.6/12.3), but the very best I ever got was 14.7 mpg (16) doing 55 mph (88 km/h). I'm a very gentle driver!
