I was talking to my neighbor the other night, an older guy, who has a carrera 4S. We were just chit chatting. I was asking him about his porsche. He mentioned he loved the rims on the jeep. I don't think he had any idea what an SRT8 was, he was happy talking about his car, so I just let it be.

Anyway, here is my question. We all know that the jeep launches like a rocket. Talking 0-60 times. Is it possible that another car could get to 60 before the jeep, but the jeep is still out in front due to the great launch?

Don't compare the carrera 4S to the jeep for this comparison, I know they launch great as well. Say...maybe a rear wheel car that will be slower off the line, but will make up time quickly.

I hope my question makes sense. I'm just not smart enough to figure it out in my own head. HELP! :D

Yes, it's possible. Lets look at ¼ mile results. A vehicle in lane one can take the win because they got out of the hole quicker, but a vehicle in lane two has a higher trap speed at the end of the ¼ because they are starting to catch the vehicle in lane one. They just haven't passed them by the ¼ mile.

I think I follow you and I would answer, yes, and here is why.

Many of us have seen the ML63 V GCSRT8 vids on YouTube where the Jeep gets an incredible hole shot (like 1 1/2 - 2 cars). Many have stated that the ML driver must have launched late because the Jeep is only .1 sec faster to 60, but it clearly isn't the case. If you watch the videos you can see that at about 4.5 secs the Jeep stops pulling on the ML. This is the point at which both reach approximately 60mph. At this point the ML starts to pull and is nearly even by 1/4 (approximately 13-14 secs into the vid.

Here is one of the vids for you to review.

yep it can happen..though its a fairly tough concept to understand..houston hit the nail on the head...its easier if you think of it in different terms..0-60 is not a really good example...take for example your in your jeep racing an srt4 with a huge turbo...you get a good hole shot and lets say your 5 cars ahead...you will be ahead but then his turbo will spool and he will start "going" faster than you and say by an 1/8 of a mile you are going um i dono 80 mph and he is going 88mph...see he beat you to 88 mph but since you have a much better hole shot your still ahead by a car lets say...since hes going faster he will eventually catch and pass you...its the basic concept of why our jeeps are hard to beat...yes they're fast but they get such a good hole shot that when we race "faster" cars they have to play catch up...i hope that helps you...and that was all theoretical haha i just pulled those numbers from i my a**

You guys have pretty much written out some of the notions that I had in my head. Weird concept, and probably pretty hard to convince people in a sportscar.

it all boils down to acceleration, a change in velocity over time.


So if you broke down the 0-60 MPH into moments of time, say 1/10 SEC increments, you would see that one of the vehicles is out accelerating the other during each of these time increments. My guess would be for about the first 3 seconds the jeep is accelerating faster, then the ML63 shows an advantage.

Mathematically, the ML63s acceleration advantage after overcoming the Jeeps acceleration would have to be enough to over come the velocity and related speed advantage of the Jeep before it reached 60 MPH.

The distance traveled would be the sum of each of the time increments distance traveled, and that formula hurts my head, so you could have a car with higher velocity (or speed) needing a shorter distance to get there.

It's been a while since school, so don't be too harsh on me if I'm wrong
