Astonishing performance, economical and CO2 emissions that can moisten the eyes of a Green Peace warrior. Is the BMW 640d too good to be true?

Being a GT, it's not as sharp or dramatic a sportscar, but comes pretty close. There are several driving modes to choose from that can be selected by a couple of buttons conveniently located near the gear stick. At a push of a button you can change the entire driving characteristics of the car and the selected mode can be easily spotted on the instrument control screen.
