Tested 640D xDrive today. I am in love with this beautiful car. The engine fits very well and has a beautiful sound. I have the same engine in my 535d xDrive, but there have bmw muffled sound. Engine sound is more aggressive in the 640D which suits the car well. The momentum and energy in huge quantities. This will be my next car in about 2 years. 0-100 km / h in 5.2 sec. compared with 5.5 in the 535d xDrive. 640D is firmer in suspension in g minor comfortable chairs but it is well for it to be sportier. I say this is the best Bmw I've driven.
