HP/Torque Curves for 325i/330i (dyno chart)

Jason · 04-16-2005, 10:19 AM

Power curves show some nice torque down low in the RPM range, with max torque at just 2750 RPM for both 325 and 330.

Very nice #'s. It'll be interesting to see how many HP/TQ is lost through drivetrain loss and makes it to the wheels.

Is this the USA version 325i ?

The torque curve is ever so slightly different than the Euro 325i graph that came with the European press release, but very slight

E90Fleet · 04-17-2005, 09:20 AM

Here is the European 325i

Jason · 04-17-2005, 09:24 AM

Thanks E90Fleet. The first two graphs posted are US spec.

those torque curves are basicly flat !! woah, thats going to make for some really fun drives !

i love the e90

These are figures at the flywheel right? Anyone have #'s at the wheel? Thx.

Are these numbers understated by BMW? I would guess that BMW is about 90% at the wheels with these numbers while all the other auto companies are reporting a 70% at the wheels vs. their printed hp. BMW has always been understating their numbers. IE Look at the 0-60 times from BMW vs. what Car and Driver was able to do on a slightly slippery condition.

Could you please explain this charts?

I want to know how fast is the 330 vs 325?

How many seconds to 0-60 for the 330 and 325

Also I want to know if the difference in price between the 325 and 330 deserve to pay more for only 40 horse power?

evoq · 05-29-2005, 01:13 AM

Also I want to know if you drive a 325 or a 330 you feel the difference right away in normal city conditions?

In what situations you can feel more the 40 horse power of the 330?

Based upon the power curves, you will feel the extra urge from the 330i in every driving condition starting from idle all of the way through red-line.

Does anyone have power curves from the 320d?

Came across this old old thread, but just wanted to say it's nice to see the torque curve so flat, just like how the car feels in real life.
