Less torque will not allow you to control the car better ...
Well, that was an extreme example to show that power is what makes the work get done. Of course for all practicality, we can't ask for an engine that produces 414hp at 2174328rpm because it has 1 ft-lb torque.

And yes, too much torque will make the car harder to control (think of coming out of a tight bend in low gear).

I am very sure you wont hear drivers say:

"it has too much torque, the car just simply can't be handled, should've got the M3"

Have you seen a C63 AMG or pretty much any other AMG?

I wonder if this is a press car "tune." I understand underrated numbers but I'm a bit skeptical here.

Well, then you shouldn't make comments about too much torque like in your previous post ...

tq = acceleration, hp = top speed. simple enough... figuratively.

The engine has different tune then a 135i, and it is also possible that they used that overboost feature during the dyno. So, this could mean that there may not be too much to gain with a cheap after market tune, if BMW is already pushing hard.

if that were simply the case, then turbo diesels and trucks would be walking all over cars like the gtr.

naw, thats why i said figuratively, technicality a loose example, but a good one for non technical discussions. of course gearing, weight, and numerous other factors are involved in said trucks.... but for likewise vehicles, it holds weight.

No, because given the much lower max RPM of a diesel, they need longer gearing...

MD Automotive dynos always read mad high for some odd reason....let's see some stock N54 dynos from there.

^I don't think this is accurate at all.

HP=acceleration, and the higher the HP, the higher top speed that can be reached (holding other variables constant).

Is it reasonable to believe with tuning this car could achieve 400HP/400lbs of torque?

HP is what you want, period. A lot of peak crank torque vs a smaller amount only dictates the characteristics of the engine.

If you take two hypothetical engines outputting 500 HP, one with 250 ft/lb peak torque and the other with 450 ft/lbs, the one with more torque would be lower revving. If they both had the same redline, they wouldn't be making identical power anymore.

It's absolutely amazing how many people have no idea what they are talking about. Torque is, practically speaking, a component of what defines horsepower. If you have more torque but less horsepower, the reason you don't make more horsepower is because you don't rev as high. Since you can't rev as high, you have taller gears and therefore less torque multiplication.

It's not rocket science, there is a reason the best general measure of how fast a car will be is called power-to-weight ratio.


Torque is good if you want to be lazy and not downshift, or if you want to have a car that is harder to control out of corners and while launching. You'll have higher resolution of control in putting the power to the ground in a GT3 or M3 than a 911 Turbo or 1M.

A car's acceleration rate directly follows it's torque curve. Daniel is right, he just didn't want to thread-crap, so he kept it simple. There is nothing to argue & if you don't understand, then spend a few years educating yourself, so you can wrap your head around what torque actually is.



As for diesel engines and high torque..? And..? What about rally cars and 700lbs-ft of torque..? 0-100mph in 3.1 seconds, etc.. (gearing is a whole other topic!)
OT: but can i just say, i have read a few of ur posts and i like ur style!!!

I wonder how much power it'd put down with some heat soak

By what many said so far after track visits; heat soak is very uncommon due to BMW equipping them with more than enough cooling.

While I appreciate a good jab it does appear that the particular dyno reads high and having to shift at 5k rpm is pretty weaksauce. All this wrapped up in a low volume car only made to fill a narrow gap in BMW's lineup and you got a snoozefest.
