My tentative calculations for my 1994 E420 come out to about 16 city/25 highway.

Hardly hybrid numbers ...but does that sound about right for these engines?

What are you getting?

but my 84 500c
sec will do 19 on the highway at 65 mph and i doubt that the 420 will do all that much better. i guess 15% better.

I drive my 96 S500 Coupe M119 about 130 miles every day (about 65 miles each way to work). Parts of the commute are 70 mph and parts are bumper to bumper at a crawl. Takes me easily 4 hours a day on the road. Gotta love this Washington DC traffic!
My gas mileage is 21 mpg combined... every time.
I've gotten mid to upper 20's on a long trip.

Not bad for a heavy car with over 300 hp.

I got 25 highway from a recent trip down to orlando from atlanta. no traffic, flat road and I was using cruise control for hours. I got like 340 miles off a tank...and I was refilling somewhere in the 14-15 gallon range....so like 340/14 = 24.2, or maybe 340/15=22.67 at the worst

...so sue me for my significant figures but its in the ballpark. I just figured the city the other day and it was like exactly 16.0...kinda funny.

Your numbers are spot-on for a W124 400E/E420 - my all time high was 26.9MPG on the highway and typical figures were 24-26MPG.

Same numbers with my .034 E420 during the weekly commute. Unless the driving conditions vary a lot (not likely), fuel economy is spot on whenever I refuel. Highway trips turn around 27-28mpg where the distance is at least 100 miles.

Like you said, not bad at all

I just averaged 26-27MPG on a 600 mile trip in my '95 E420. Better economy than my old '82 240D!

This is for an all-city driving, with lots of cold starts, stop and go, short trips.

17mpg. When I do 50% highway driving (the rest are short trips in the city), I get about 21mpg and best was 25mpg (75% high speed highway driving)

Not bad I think..

Can't beat my 85hp Ford Escort though. 80mph blast to NYC and I average 44mpg! It sure felt SCARY at 80mph though.
