    • Controversy: Is the SLS AMG faster than the 458 Italia stock for stock?

      A debate has been raging on the BenzBoost forums and we decided it was finally time to put together information on these two cars to help sort out the video below. There are three races and the SLS gets the jump in the first two. In the first race the SLS is lined up ahead and gets on the gas first pulling. In the second video a mix-up in the honks has the SLS jump again leading the 458 to have to run it down which it can not. The third race is the cleanest with the SLS still pulling away and rather quickly.


      Now, this has led to people from each side yelling and screaming at each other. Here is what we know, the SLS dyno's more on a dynojet stock. There are variables involved of course but based on the graphs we have thus far the 458 baselines around 450 wheel and the SLS around 488 wheel. Advantage, SLS.

      458:

      SLS:


      So power favors the SLS but what about the weight? Well, Road and Track weighed the 458 Italia at 3490 pounds. The SLS AMG comes in at 3795 pounds. 300 pounds in favor of the 458 Italia although this is mitigated more from a roll than from a stop.

      This may help explain why the 458 Italia gets a better elapsed time in the 1/4 mile versus the SLS stock for stock. It's rear engine launch is also a large factor helping it get off the line better. Going back to Road and Track, the numbers are 11.0@128.5 versus 11.6@124.3 for the Italia and SLS respectively. 0-120 numbers favor the Italia by 1.2 second stock for stock, not a small difference.

      Shift speed has been stated to favor the 458 with the SLS at 100ms to its 40ms. This disparity seems too large for the same technology from the same supplier, Getrag. As a matter of fact, they are basically the same unit. So is there really that large of a disparity here? We don't think so.

      So how do you explain the outcome of the video? The only explanation is that the SLS is not stock. Logically, this is the only conclusion one can reach to explain how the SLS leaves the 458 the way it does. The weight is not as large of a factor once the cars are moving but even so we should see the 458 slowly pull not the SLS jumping out and destroying the 458. A stock SLS simply is not capable of it based on the data presented here. The stock claims are likely misleading and for SLS owners to boast. This is why we prefer track numbers for support but even without them a video can still be broken down. If we are incorrect, someone do this same race with two stock cars and prove us wrong. One thing is certain, both are fast cars and examples of some of the best vehicles available today.

        SLS 563 hp @ 6,800 rpm; 479 ft lb of torque @ 4,750 rpm

        458 562 HP, 398 lb-ft of torque at 6,000 RPM with 80% torque coming in at 3,250 RPM

        458 Italia has one less HP yet it's torque comes in at a lower RPM than the SLS.


        Those are just the crank ratings.

It's not like the SLS is right there with the 458 in the quarter mile; it's almost a full second slower. And the argument about the SLS having more torque from a roll is baseless as we have seen so that argument is also worthless. So what are we left with ? Oh I know....someone is full of $#@! and this is the internet - BIG SURPRISE.
        I find it hard to believe that SLS is stock, I really don't know.

        I would like to see more races but with the interest this is generating I'm going to put together what I know for a front page article.

        True. But you can use the info to get 100-250 km/h time, right? 458 does that in 12.73 while it takes 15.34 seconds for SLS.

        I would like to see some 60-130 from SLS too.

        Lying is not going to get you anywhere. You mentioned in post #11 that you were testing your 458 between 60-130 and you got 7.9-8. Now suddenly you have a twin turbo on it. looool. look whos throwing BS around

        Get your "twin turbo 458", I have an SLS in mind that will have no problem runing against you in Abu-dhabi, oh and its not stock :-)

        I see no sense of humor in you. I was just joking around.

        But that's good to know that the SLS you have in my mind was stock, but now it is not stock! So what is it then? Stock or not Stock?

        Did you see the "I was just joking around" part? It's %100 stock ATM, Akrapovic exhaust and a possible Eurocharged tune will be done soon enough.

        And keep it civil or you will be on ignore list.

        You guys apparently take your cars with you when you do business trips to outside of your countries. I don't.

        BTW i don't see how you got involved in this conversation, i don't have anything against you sir so i don't take the imaginary 458 part
