What is your 0 - 60 time on each diesel you own? - Page 20 - PeachParts Mercedes-Benz Forum

my 1995 W124 E300 Diesel, first timed 0-60. looks to me about 14-15 seconds. here's the video. flat surface. 63 degrees. about 1500ft above sea level

30 to 60 seconds, depending on traffic. But my Beetle gets 40 mpg as a result.

My 280Z has gone 0-60 in 3.9 seconds.

Just ran mine the past two days in the low 80's temp, 0-60 was 13 seconds the four runs I did.

Wow....so a 617 turbo W126 is faster than a 1995 N/A E300. I never imagined that would be the case!

My 300SD can pull a slight uphill 0-60 in about 12.8 seconds with two people and junk in the car and a nearly full tank of fuel.

I need to re-test on flat dry ground with 1 person and no fuel/junk. I bet I can get an 11something time.

Either way, my gasser can kill any of our diesels...it can do a 0-60 in around 8 seconds flat....I have not extensively tested/timed it, but based on how fast it is compared to the diesels, I am sure its right around that!

It's not the case. Factory spec on the 126 is about 15 seconds 0-60, spec on the 1995 E300 is about 13 seconds.

That is waaay better than stock performance. Either your engine is making a bunch more power than stock, or the test method is flawed (need to test on level surface, verify speedo accuracy with GPS, use stopwatch, etc.)

That would be truly impressive from any 126 with a 617.

Yep... my 500 has clocked many sub-six-second runs. Factory spec on the early 90's 300E is right at 8.5 seconds.

0-100kph (0-62.4 mph). In the mid-80's, when the USA still had that silly 55mph speed limit, the brochures had the 55mph specs. Later on they reverted back to 60mph. Across the pond they use 100kph, and this is also the spec used in the TDM (Tech Data Manual).

Thanks for clarifying this. I have immense respect for your knowledge and friendly demeanor, but I was beginning to wonder how the TDM 0-60 times were arrived at.

I'd about decided these must be minimums, that if you fall below (takes longer) it's an indication you definitely need service.

0-62.4 can be quite a bit different than 0-60. Sometimes it can mean an extra shift. In a moderately slow car it can be a full second or more. (In a 240D about 3-4 seconds.

)

After reviewing that excel spread sheet, I've concluded that those are still rather conservative 0-60 figures. In the Motorweek video of the 300D 2.5 you can see that they spool up the turbo before releasing the brakes. Resulting in a 10.6 s 0-60 time.

There are so many variables, I'm not going to quibble about small variations, but 4 s or more on a 0-60 is substantial.

Mine has always been that quick. Just recently I did a 0-60 with my wife doing the stop watch. I had to pull out onto a road to do it, there was 2 people, a ton of apples in the back seat (

), 1/2 tank fuel, and a bunch of junk in the trunk. I had her with stop watch, I said "Go!" and she hit the clock right when I slammed the go pedal, I turned out onto the road, and said "Stop!" right when it hit 60. Time was 12.89 seconds. Not bad considering I had to make a 90 degree turn and had quite a load in the car. I'll make a video soon to prove it if I have to.

My fancy radio head unit also has a stopwatch function like the iphones, using gyros.....it will do a 0-60 clocking as well, it begins when it senses forward movement on takeoff, and will stop when it senses you let off the go pedal when you hit 60, or if you manually click stop) Pretty sweet.

The TDM says in a footnote (paraphrased) :

"Load = 2 persons; time = ±7%. The 7% range covers not only variations which are due to the permissible engine output tolerance, but also the permissible deviations which may be vaused by the tires."

They don't mention fuel load, though. But without a passenger, and on the better side of the 7%, that could easily translate into performance a second or so quicker than spec (if your car is running well).

Absolutely correct. On some cars it's a tiny difference, on others it can be significant if a gearshift is involved.

I always power-brake before launch. It doesn't build much (if any) boost pressure, though... I've got a boost gauge and never see it do much until the car starts moving. I discussed this with a fellow in SoCal who drag races his E420, he had not been power braking. He started power braking for grins, and found there was a sliiiight improvement in takeoff, but we're talking a tenth or two at best... there's no smoking gun here that will shave a full second (or more) just by different launch technique.

Definitely! In general, if your car is more than 1-2 seconds slower than the factory spec, and you're not well above sea level (like, 4000' or higher)... something is wrong.

Have you used a hand-held GPS to verify speedo accuracy at 60mph? I've seen them be several MPH off, which can translate into a pretty big change in the stopwatch readout.

Ooooo, that does sound cool. What brand / model / etc? Have you tried it out?

I downloaded an app called dynolicious that runs onan iPhone or iPod Touch.

This little app will give you your 0-60, 1/4 mile times plus engine HP and a bunch of other stuff. It does not use teh car's speeedo (which are often wrong). the iPod/phone has an accelerometer built in.

http://www.nextautos.com/iphone-app-puts-a-dyno-in-your-pocket

I just tested my '85 300D turbo. Up to temperature but only just. Flattish rd, not much wind.

0-60mph 15.7sec
1/4 mile 20.7 (68mph)
max bhp 89 (assuming 20% transmission loss)
I have tried this before with stopwatch and speedo reading, but this is a much better way!

PS: Did same run with our '72 SL and it just beats the published data. (9sec 0-60 and 17.2 1/4 mile)

That can't be right. No way you can do 15.7 s with only 89hp. I think the transmission loss is less.

I've calculated my car against other car's speedo's while driving, and it was dead on. It also matches those radar things, and I've gone 60 on the highway and timed a mile.....exactly 60 seconds. So it is quite accurate.

My head unit is of the Kenwood Excelon series. Fancy.

It's the other way actually. If I hadn't entered the 20% loss, it would have come up with 71.2HP at wheels. If transmission loss was say 25%, then engine net bhp would be about 95.

The plot shows peak HP achieved after about 4 sec after which it is steady for 7 sec then starts to drop off as I guess momentum takes over?

Anyone know where we find transmission losses?

The advantage of the iPod/iPhone dynolicious app, is that you don't have to time it at all. It figures out the time and speed based on the accelerometers in the unit.

You just hit the start button. When it turns green, you floor it and keep it that way until unit beeps to say the run is over. Doesn't use external timer or car speedo and no gps required. Besides that is costs just $12.95 IF you already have an iPhone or iPod Touch.

I have been using it on same section of flat road. Best to go both ways to take out influence of slope or wind. Also need to actually GO when unit says GO!

BTW - My '85 300D is stock. But the speedo reads high by about 5kph. Suspect modern tires may be different diameter from originals.

They proved on 5th gear in the UK that the Dynolicious app is at best only within 10-15% of the actual time.....and often is way off.
