I had my camera today, decided to do a take a quick video on a nice wide open straight away.

SL600 0-110

Too bad it was a rolling start-- you're speedometer said 6 MPH, so you're time to 60 was slower than from a 0 start, but nonetheless, awesome video. Now, time for me to go and replicate that action in my SL6.

wow!! very fast, sounds great

blueSL

Very quick car, all we need now is someone with an SL55/65 to do the same! Looks to me to confirm sub 5 seconds to 60 and sub 10 seconds to 100 and I doubt there are many cars where you could do the same with so little drama.

This video shows how the gear ratios of the 5 speed are spaced out compared to the 7 speed on the SL500 where the revs drop less when it changes.

StephenK

This was the hardest I ever drove this car, it was a blast, the power is amazing, the control is amazing, it definately feels like there is plenty more power to go well past 110.

carlosfernandez

nice job and wih your comments I feel that you enjoy that ride.

NOTKTS

I believe the car is capable of 180+ but yet it only has a 160MPH gauge... thats my only pet peeve about the car.

StephenK

This car probably is capable of it, but since it is electronically limited at 155 it would take some modifications to find out. Some of the performance upgrades offered on the market raise the limited speed up from 155. Maybe someone with Renntech would know the true speed the car is capable of.

NOTKTS

In their package they raise it to a 196

StephenK

196, that would be scary.

I wish my town had some sort of auto track where individuals like myself could go out and really test the performance of their automobiles, but so far I have not been able to come across anything.

I notice you hit 110 pmh in third gear.

Not that there is direct similarity with a R230 SL600 and my R129 SL SL500 ... however here is my story.

I was out roaring arround in my R129 SL500 a few weeks ago. I had shifted into 4th gear for "sporty driving" ... then proceeded to sprint up to 135 mph for a short period of time.

Since I don't spend too much time studying the instrument cluster at that speed ... it was later in my drive that I was still in 4th gear!

I realized I had done 135 mph in 4th gear. I guess 4th gear does get you up there in speed.

I don't recall hearing any excessive reving ... and I guess the rev limiter would have intervened.

NOTKTS

Thats why we (I) end up having to do it on public roads.... Dont flame me, you can argure that there are tracks in the area, but nothing for 190MPH. Except if we were allowed on the Daytona Speedway... cough cough fat chance. I dont remeber the last time it was open to the public aside from group events. So we end up heading out to the highways to get it done at 3am. If any cops moniter this board my evil twin brother went 192Mph on the 417 exit to I-4. He made sure that there was no other cars on the road. Its just a reality. Agian dont please dont flame me its just my .02 cents.

**** thats quick be safe!!!

NOTKTS

"He" had to let off because it felt like the front was lifting up and he didnt want to die that night.

Lexani

I want to race you. I cant wait. :v

NOTKTS

Bwahahaha! I cant wait either, tell you what well go from 150! HAHA you only have 5mph more. I think that it will be a very close race. Just got the latest dyno numbers from John… :v :v :v :v! Trying to figure out why acceleration drops at 150, he's doing some road testing tomorrow for the latest performance figures. Ill be sure to let you know !

ChrisB

I took my R129 out yesterday and did the same thing. I set up 2 lap tops running side by sided. I have done several runs against you and as expected you always win!

Pausing both clips as the tacks are sweeping toward 1,00 rpm, then hitting play simultaneously sets off a nice race. It was fun.

SL 600 hits 100 mph ... R129 SL 500 is at 82 mph.

It is impresive how quickly the SL 600 continues to accelerate at high speeds.

SL 600 0 to 60 mph in just under 5 seconds
R129 SL 500 0 to 60 in just over 6 seconds.

SL 600 0 to 100 mph in 10 seconds
R129 SL 500 0 to 60 in 14 seconds.

Any one know their physics formulas well enough to determine the SL 600's lead in feet at the 10 second mark?

I don't know how to post links to video clips .

I'm going now to race the R230 SL 500. This will be a bit more even !

StephenK

If you want I can host the file for you, just email me if you want me to do that for you.

SL600s are much quicker than just under 5 seconds. I have a 355 and an M3 that do it in 4.5 and the SL600 is much quicker. I think they are also faster than my friends GT2 and the Gallardo. I definately believe Road and Track's sub 4 second 0-60 times.

ChrisB

I found a post that contains a graph of the gears of the 5 speed R129 transmission. Both 4th and 5th gears go to high speeds without hitting 6,000 rpm. Thats why I did not detect unusually high revs.

The R129 5 speed transmission shfiting and acceleration pattern for compairison:

Will be posted later. Sorry!

I can not wait to drive the R230 SL 600!

R129 1999 SL 500 performance run

For compairison purposes.

Mmmm

Very quick, really pulling hard, no fuss at all

Neither an M3 cab nor an F355 cab will hit 60 in 4.5. M3 cabs are in the low 5's, and the F355 Spyders were tested from 4.9 (Motor Trend) to 5.3 (Road & Track) 0-60.

RENNtech-er

velocity (v) = acceleration (a) multiplied (x) by time (t)
hence, a = v/t
For the R230 SL600 at 100 mph (which = 146.7 feet per second), we have
a = 146.7 fps/10 seconds = 14.67 ft/sec. squared

Now, distance (d) = a/2 x t squared

For the SL600, d at 100 mph = 14.67/2 x 10 squared = 733 feet

For the R129, a at 82 mph = 120 fps/10 sec = 12 ft/sec. squared

d at 82 mph = 12/2 x 10 squared = 600 feet

The R230 SL600 is (733 - 600) feet ahead of the R129 at the end of 10 seconds = 133 feet

I think! My BS in Physics was 37 years ago.
