there's a saying among automotive enthusiasts which goes " there's no replacement for displacement"
no doubt 1.6k maybe a bit tooooooo bloody high to pay for such rubbish piece of road that our stupid government is giving us, but the sheer enjoyment of driving a 2.8, 3.0 3.5 v8 or even a 540i with a 4.4 v8 is just incomparable. the 5series being a heavy car is just a tad underpowered with the 2.5 and below engine.
the availability of all the torque on demand, just bring a smile to your face every time you take it for a sprint. be it just a short drive around your neighbourhood or a drive on the crapy highway with idiots hogging the fast lane. at times like this is where you find the enjoyment of having a bigger displacement engine, with all the torque in hand, all you need to do is just give the pedal a slight push and you are off smiling away...
