R320 CDI Mpg?

What are people getting for their fuel economy on the '07 R320 CDI? I was thinking about getting one of these versus getting another E-Class because of the great value for money, they don't seem to be selling very well and dealers seem to be flexible on them.

Take good care of your car and it will take good care of you.

I've had my R320 for 6 weeks now and love it. Tons of room and unbeleivable milage for a vehicle this big.
I've been averaging about 9.6 l/100km (24mpg us, 29 mpg imp.) and that is mostly city driving. I can get it down to 8.0 (29 mpg us, 35 mpg imp.) crusing at 110km/hr on the highway. And to top it off Diesel is .06 / litre cheeper than regular gas here in Canada and about .16 cheeper than premium.
Saving a ton of money on fuel!!!

Be Prepared for Lower Window Sticker Fuel Milege Figures on 2008 Models

Starting with 2008-model vehicles, the Environmental Protection Agency is revising its tests to better reflect real-world driving conditions. Kiplinger has developed a tool to provide an estimate of what the new EPA fuel economy numbers will be for about a thousand 2007 models under the new tests.

City mpg will be reduced by 12%, on average, and highway mileage will shrink by 8%, according to EPA estimates. Gas-electric hybrids and some other high fuel economy vehicles could see even bigger reductions.

Current standards were developed back in the 1970's, when cars and driving styles were far simpler. The new standards factor in higher speeds, stop-and-go driving, more aggressive acceleration, use of air-conditioning and driving in colder temperatures.

The new standards will more accurately reflect "real world" fuel mileage instead of the inflated figures that most vehicles never achieve. While the new testing methods provide more realistic figures, many will be in for a shock when they see the lower fuel mileage figures. For example, when comparing the current 2007 model year fuel mileage figures to the 2008 model year, the EPA fuel mileage figures on the window sticker for the R Class will now be (No CDI Figures Yet):

I have an R320 since the first week of March with about 1,500 miles driven.

My average MPG is around 24 miles/gallon, which is 60% city and 40% highway. The AC or Heat are always on, settings for all three zones around 68-70-72. A month ago diesel price was $0.05 more than premium unleaded (91 oct). Now diesel is $0.05 below regular unleaded (87 oct) and almost $0.30 below premium unleaded (91 oct). Miles between fillups are well over 500 miles / tank.

Real Sweet.

Depends a lot on your driving style

Recently, I averaged 24.1 mpg in my R350 on a 310 mile round trip from New Jersey to Maryland on the interstate highway. My average speed was 62 mph and I had the airconditioning set at 72deg F, the outside temp was 82 deg F.

I found that accelerating steadily, as opposed to stepping on the gas unnecessarily and keeping in the middle or right lane with cruise control set at a steady 70mph and slowing down (instead of coming real close to the vehicle in front and braking) when there was traffic ahead, went a long way in getting this rather impressive figure for such a heavy vehicle. I did however, do some short stretches at 80mph and even tried 95mph for a few minutes - the 24.1 mpg figure includes these short high speed runs too.

8.4L/100km or 28 US mpg on highway ... sweet!

Getting about 11.4L/100km or 20 in the city. Not so great. But where I live, there's lots of stop-and-go driving.

Ultra-low sulfur diesel here in western Canada is considerably cheaper than Unleaded, usually about 15% less.

Very happy with the engine & transmission on this car. Beautiful piece of engineering, IMHO.
