Facts are facts...It is true that the 4pot valvy runs out of steam from early 4th to 5th due to the gearing ratios...So what I tested was on 1st, 2nd, 3rd to 4th. And that;s where I was able to capitalise the power window of the valvetronic.Also, I think all BMW cars coming from UK are underpowered due to the very strict emission control requirements. So eg, if the 525i comes with 192Bhp on paper, BMW cars in UK would experience a power degradation of -10BHp or so....(i think); and this coupled with the taller ratios in the 5er, it simply couldnt keep up.. IF we were to test it on the highway, I would have been creamed big time  :beaten:</blockquote>
