Stupid question
Just curious, I searched for this question and got lots of threads but no real answer. Regarding the GS400 vs. SC400, how is it that a 10hp/10tq difference make the SC400 a full second faster to 60mph? It must be some sort of "magic horsepower", or marketing.

magic hp in the exhaust design etc.

Still wasn't answered exactly in that thread. I've wondered this too, what makes the GS400 so much faster than a SC, clearly a 10hp/10tq difference can't make a huge gap in times like that now can it?

Other than likely different ratios, other aspects of our transmissions could be making a difference, though; things like the smooth shift deal of ours that a lot of people like to disable.
I mean, remember, our SC's aren't race cars and weren't designed for all-out performance. It's similar to the criticism the BMW 850 gets. These are grand touring cars, made for swift and comfortable speed with a bit 'o style. Not that the GS is a race car, either, but it was designed more as a luxury performance car. I put it more in line with the faster of the BMW 5 series of the time, though not M5 level.

Yes, there's lots more to 0-60 than just power to weight ratios. I think that's the take-away from these exercises.

So, (possibly) lower gearing, more torque and HP, better aerodynamics... Those sound like perfectly reasonable factors in a better 0-60 time.

I would be interested in knowing what the gearing difference is, if there is any difference. I was under the assumption that the GS400 and the SC400 had the exact same drivetrain; same engine, same 5 speed auto (A650e). Perhaps one was tested with traction control off vs. on? Has anyone run both side by side? Perhaps the tires hook up better on the GS? I drove a GS400 and wasn't exactly impressed by how quick it was, perhaps these numbers are an "estimate" for marketing purposes?
As far as I know, aside from the exhaust manifolds and y-pipe being different, the cars are identical. I mean, 10hp/10tq is not enough to give you 0.6 seconds difference, if so then I don't understand power to weight ratios
I guess what I am hoping is that the SC400 can match the GS400 with very little, OEM mods, like changing to the newer exhaust manifolds, as I am planning on picking one up really soon. 5.7 is exactly where I want to be as a daily driver, 6.3 is kinda slow Any aftermarket ECU's available or decent (though relatively quiet) headers that can get the SC400 there? Can't believe I have to write this, I mean the fact that these cars aren't identical in real world performance is beyond me.

Pffst...no VVTI, not enough power :-D Pre-98 models would almost need a supercharger to compete :-( Plus, the pre-98 intake manifold is just too 1980's for me, single length runners, booooo! Sorry, just having fun
