Looks like more power than a stock N54

i just saw it too... best run was 293hp and 296tq on the N55 135i DCT.
so assuming a 15% drivetrain loss, thats about 345hp and 350tq... that is also assuming the DCT transmission isnt more or less inefficient than the 6AT or 6MT. this is very good news for the new N55!!! if this is true, then the N54 335is must be seriously underrated as well if its gonna stay ahead of the standard N55 335i. |

It looks that the power up top is higher (8-9hp more than the N54), but the torque is lower (-10 Nm).
I am comparing these graphs which I suppose are done on the exact same dyno (used by BMS). However, the N54 has an automatic gearbox, higher losses compared to the DCT.

and you can see from the dyno that the torque curve peaks quicker, and is a lot flatter .. thats what you feel in the car.. its power delivery is a good bit different than the N54... it reaches the its peak torque in a shorter time and smoother delivery... no?

I wanted to believe your review just didn't want to have my hope dashed later Yep the N55 is trickling down to west coast as we speak, I have a vert with auto to test at my dealer. So I need to drive my 535i in sport mode often now and reset adaptaion on the way to dealer. I'll let you know my impression. |

On 91 octane, the N54 graph begins at 2000RPM, with 290lb-ft at 2200RPM, while the N55 has 290lb-ft from 2700RPM but it begun too late at 2500RPM so you have no way of knowing what's below that.

Terry from BMS said that "the engine is softer down-low", "there is increased turbo-lag compared to N54" and "overall it is a downgrade from N54". So how can we believe your "the car has an afterburner" review ?

Hard to say cause the dynos is from different days, I'll say N55 is about the same as N54 with more lag. I am glad I'll have 6-sp on my N55. |
