Is performance really better when shifting at lower revs? I rarely rev to red-line myself, but are we sure it does not offer better drag strip performance to do so? I know the torque will drop off at higher revs, but is the curve really so steep that rwtq above 6300 drops below that of lower revs in next gear and for all gears?
Little known facts about BMW: 1) The N54 is still in production and used in the current Z4 35i and 35is. 2) In a Z4 you can get sport+ steering combined with normal suspension etc by selecting DSC=off. (Update: DSC=off also offers sports steering in the M135i) 3) All Z4s with 19" wheels are still only offered with the worst performing OEM tires ever sold with a DCT equipped BMW (Potenza RE 050 RFT).
