No, I have not driven an E320 CDI. I have seen dyno charts, hp and torque outputs, curb weight and other statistical figures.

1st gear, the E320 CDI is putting out a maximum of 3520 lb/ft at 1600 - 2600 rpm.

2nd gear the E320 CDI is putting a maximum of 2356 lb/ft.

3rd gear = 1379

4th gear = 978

The E420 picks up 90% of it's peak torque at 1500 rpm.

1st gear, the E420 is putting a maximum of 3244 lb/ft;

2nd gear the E420 is putting down a maximum of 2005 lb/ft.

3rd gear = 1173 lb/ft.

4th gear = 832 lb/ft.


The E420/E430 have VERY flat torque curves which enable them to achieve maximum torque values throughout the engine speed range. The diesel tapers off quite a bit after 2600.

Redlines are significantly higher than the diesel, so you need to multiply by 25% and add this value to the extra power the V8's really have.

I predict the E420/430 will start reeling in the CDI even before 60 mph(when 2nd gear ends on the CDI and 2nd gear continues on the M119/113). The torque peak is very narrowly spread out in the diesel. Even the 320 beats the CDI to 120 mph according to C&D(wait, not sure) by over 5 seconds.

Europe gets 0-100 km/h in an E320 CDI in 7.7 seconds. Albeit with slightly taller gears (2.47 diff versus 2.65). But the gearing should not make such a staggering difference in performance ability. I believe the euro tests are "foot to floor, and nothing else".

"Mercedes, by contrast, should have no trouble moving each and every E320 CDI it can bring in. Our example, in Euro trim without the added sound deadening we'll get, was the least dieselly-sounding and -acting of this bunch. It outperforms its gas cousin by a full second to 60 mph (6.4 seconds) and by 0.9 second and 3 mph in the quarter (14.9 at 93), and it makes 4 dBA less noise when running those tests. Stay on the throttle, though, and the acceleration curve flattens out quite a lot in top gear. The diesel will run to 149 mph, but the gas engine hits 120 mph 5.5 seconds sooner. But in all the driving most Americans do—scooting away from stoplights, passing on two-lane roads, and cruising the superslabs—the E320 CDI struck us as vastly superior to the base E320. We averaged 28 mpg overall, but on typical highway commutes we routinely topped 40 mpg driving at 75 to 80 mph. And check the European fuel-economy stats: 25 city, 44 highway—nearly the same as the four-cylinder PT Cruiser CRD, but with 82 more horsepower and 148 more pound-feet of torque. What's not to love? Priced right, perhaps midway between the E320 and E500, this car strikes us as a must-have."

 

here is my dyno of a 3 3rd gear pulls in my 430...don't pay atention to a/f it wasn't attached. the shop did a horrible job at the dyno and i only payed them 20 bucks for there time. its obvious my numbers are low...man i'm still made

but i still believe that u get the general idea of lines



my miles per tank average 250-280. i am very spirited though. i never have figured out what the mpg's are

 

Those are about the same #'s I got with my stock E430, however I had a bad cat, airbox was full of dirt and had snow tires on. I also filled my tank and got 260 miles before light came on, again I have on snow tires.

 

And another quote:

" “The E320 CDI here on my right side, which we introduce this April in the United States, is such an exciting product,” said Jürgen Hubbert, head of the Mercedes Car Group. “In its combined cycle, it has a fuel consumption of 35 mpg, a figure unmatched by gasoline engines with similar power and torque. On the other hand, it accelerates from zero to 60 mph in only 7.3 seconds,” Hubbert said. In comparison, the 2004 E320 with a gasoline-fired 221-horsepower, 3.2-liter V-6 gets a 19/27 mpg city/highway rating and hits 60 mph in 7.1 seconds."

 

750 miles. (Highway)

Usually get about 600. I am deliberately hard on it.

Drool on gasser boys.

can some one post the size of the 430 tank so i can do some math

 

NICE... can't beat that!! I'm averaging 21.7 p/gallon... 18-19 city, 23-24 hwy, all on very spirited driving.

 

I think it is 21 or 22 gallons. Should be the same as the E320 tank.

 

21.2 gallons... It's in the manual as well with a 2.6 gallon reserve

 

I've gotten as high as 26 MPG, but that is by driving very conservatively. "Normal" driving gets me about 22-23 MPG. ('02 - 430)

 

Hate to tell you guys, but driven carefully, the E320 yields outstanding gas mileage. Just made a 2011.9 mile roundtrip from Griffin, Ga to the Bronx, NY. I fueled four times, for a total 68.46 gallons. Started and finished at the same fuel pump, (for maximum accuracy.) The AVERAGE fuel consumption was 29.39 mpg, but adjusted for the over-size tires I'm using, you have to correct this by a factor of 1.04 = 30.57 mpg, in order to compensate for the actual distance covered. My trip also included more than an hour in delays during monumental traffic jams east of Allentown, PA, south of DC into Virginia and coming home during Friday evening's rush hour through Atlanta. (The return trip, door to door, took 15:25 hrs for over 900 miles.) My speed on the interstate highways never exceeded 80 mph. The car is a 1998 E320, presently with 89,000 miles on it. (I owned several Diesels before and am perfectly happy not to make jack-rabbit starts.) I hardly ever excede 2,000 RPM during accelleration, which may contribute more than anything else to my success in getting great fuel mileage. :-)

 

By the way, I ended up going all the way and I got an E55. I get 200 miles a tank now . LOL

 

I took some photos of my cluster showing around 400+ miles on a tankfull at the point when the low fuel warning light came on, so 450 miles on the reserve could easily be reached. This on a 430 running around 75% highway driving.

 

Just came back from a long trip and logged 651.9 on a tank, mostly highway. I'd estimate I still had at least 1.5 gallons of the 3 gallon reserve.

 

"gota love those diesels..."

 

Wow. It looks like you drive 100mph all time.
