E46 330i = 155bhp/tonne
E92 335d = 171bhp/tonne

16bhp/tonne is very little and you'dneed monsterous amounts of power to leave someone behind completely, like i imagine you were expecting?

Don't forget, as cars get newer, their engines may churn out 15% more power, but then they always end up weighing 10% more than the previous model! The F30 i think has broken this mold a bit as it is very similar in weight to the E90.

Compare the 1/4 mile times (about 2 seconds difference?) and you will only have a few car lengths from 0-100. Given you are probably at 70-80 when you nail it you are unlikely to obliterate them in just 3-5 seconds of wide open throttle.

Depending upon how close they were following, you can also consider the reduction in drag as a result of being in your wake - drafting. To avoid this I nail the throttle and pull over to even things up.
