Launch Control......

I came across this article from 2010, thought it was interesting. I would think my 135 would have similar numbers to the M3 listed here. I have no idea if anyone posted this before......

Ah, well it is the same transmission, however the M3 has different software and much more settings/modes.

I'd imagine it'd be pretty close though. My car with the PPK is rated at 4.6 0-60

Motortrend or whomever managed a 4.7 for a stock 135i with a DCT. But stock for stock. A M3 is going to have a faster 0-60 time than a 135i.

The MotorTrend article I saw rated the 135 at 4.7 seconds, but made no mention of Launch Control.

It was some car reviewer since I said it was Motor Trend or someone and the time was a guess. It was around that 4.7....maybe 4.6 or 4.5.

The S65 makes roughly the same torque as the N55, but it has to rev 2,700 more RPM than the N55 to hit that peak. There's not much between a stock E9X M3 and a stock 135i in a straight line. With mild tuning, the gap shrinks to almost nothing.

To me the best thing about the S65 is that sound!

I like the rod bearings

The S65 hits peak torque at 3900... But basically it's flat from about 2800 on. So it has the same torque but considerably more horsepower due to being able to rev higher and hold torque to nearly it's 8400 rpm redline. Due to the high rpm nature it is geared more aggregate so the actual torque at the wheels (acceleration force) is higher even with the same engine torque rating.

I've owned both cars (e90m3 and 135i). You are kidding yourself if you think the 135i is the same in a straight line. Stock for stock the M3 is unquestionably faster even in a straight line. This is what the paper numbers say, what dynos say, drag strips say, my butt dyno says, reviews say, etc.

However being a FI engine it is super easy to extract extra power from the N5x engine assuming you are willing to spend a little bit to modify. Once you put a few dollars into the N5x you can certainly match a stock or lightly modified E9x M3 in a straight line.

Yeah, 1,200 (where the N55 torque plateau begins) + 2,700 = 3,900 (the torque peak of the S65).

I also never said the 135i is as fast as an E9X M3 in a straight line. BMW would never allow such a thing in their vehicle lineup.

But yes, a few dollars spent for mild tuning and the high strung nature of the S65 isn't enough to keep the high torque, directed injected forced induction motors at bay until you hit the track and get heat soak.

The S65 "torque plateau" starts much earlier than its peak. It's within striking distance of peak torque far before 3900.

You make it sound like you need to rev the S65 to the moon to get it to move. It's simply not the case. The S65 has one of the most flat torque curves I've ever seen. Then you add on the fact that it is geared higher (numerically) to take advantage of the extra rpm and yes it makes more true torque to the wheels than the N5x... I think we agree there.

I think we also agree it's easier to extract a bunch of power from the N5x. Like I said I have owned them both , in fact currently own the 135 and not the M, but just telling it how it is.
