Are these stats accurate and if not do you know what the stats are for what I have listed below?

Year, 2000
Description, CLK 320

0 to 60 mph 6.9 sec
1/4 mile (E.T.) 15.2 sec

Final-drive ratio..........3.07:1

Wheelbase..........105.9 in
Track, F/R..........59.3/58.0 in
Length..........180.2 in
Width..........67.8 in
Height..........53.0 in

CdA = 6.4976
Frontal area..........21.4 sq ft
Drag Coefficient = 0.31
Curb weight..........3240

(F:0.9-2.0" / R:0.8-2.0")
Pitch Charachteristics =
Rolling Resistance =

Pitch = 2.0
Roll = 2.5
Drive Train Losses = 15.0
Rolling Resistance = 0.015

Min Speed RPM = 2000.0 @ 000 mph
Max Speed RPM = 5700.0 @ 000 mph

Min Speed =
Max Speed =

According to the aDyno Android application "Need Pitch Characteristics for accurate 0-60, quarter mile times."

My 0-60 currently reads 6.19sec

This run was from one stop light to the next. By the time I got to 60 it was time to slow it down.

No brilliance on my part, I just report what they tell me

Per the 2001 MB USA press kit (I tossed / can't find / lost the 2000 kit but they are the same), these are the differences:

• MB doesn't list quarter mile times.
• The height is listed at 54 inches (but they list that for the 320, 430, and 55)
• I don't know what CdA is, byt the aerodynamic drag (Cd) you listed is right.
• I don't know the frontal area.
• US models were rated at 3265 pounds for the CLK320 coupe, but they have 4 cats rather than your two. That might be 25 pounds.

I don't know pitch characteristics, rolling resistance, or drive train losses. They don't list that in the new press kits either.

I keep a lot of W208 stats here.

I do know your speed @ RPM numbers, but these are only good if the tires have the same diameter as the original Michelins (close on others though):

1st gear @ 6000 RPM 38.6 MPH
2nd gear @ 6000 RPM 63.4 MPH
3rd gear @ 6000 RPM 98.3 MPH
4th gear @ 6000 RPM 138.7 MPH
5th gear @ 4800 RPM 155 MPH (electronically limited)

I hope that helps.

Thanks Boss

Ok found the formula.. http://ecomodder.com/wiki/index.php/...t_of_Drag_List

CdA formula = Cd * Frontal Area (Duhh) lol

So CdA = 6.634 given the Frontal Area number is correct/accurate.

I visit your site often for reference and information.

My diameters of my 20's is pretty much the same as stock. Can't remember exactly but it was only off by just a few i.e. 0.02.

According to the aDyno app, to have a accurate 0-60 I need the following information:

[Pitch Characteristics 2.00 degrees/G - (pitch angel @1G acceleration)]

Hopefully the "Oracle" will have answers - GGLE

You takin' to me?

Williams707

Yes, show me your 0-60 times

dlbehrns

back in the day, when I had a black series motor, I couldn't afford the gas as the mileage was horrible so I sold it and settled for my good old 320. The 1/4 mile times I never bothered with. It was my daily driver. Hey, I have a great bridge in NYC I could sell yah if'n yer interested.

Pretty much got all my details dialed into this aDyno android application.
Just need the Rolling Resistance data which I emailed Nitto tires.

Did another 0-60 run today and clocked in at 6.174 secs

Is there a way to remove the speed limit?

dlbehrns

Yes. You have to take or send your ECU to a chip tuner that will reflash it for you.
