I swear I've haven't clipped a curb in decades. And yet there I was, cutting in front of a line of traffic in the great Rhode Island tradition, when I heard the muffled whump of the 645Ci's rear tire cresting concrete. It's not the kind of sound you want to hear when piloting a $70k "Ultimate Driving Machine"-- if only because it makes you seem a lot less than the ultimate driver. Not guilty. I blame mechanical foul play.
Firstly, the 645Ci is a hard charger. The moment your right foot touches the go pedal, every one of the coupe's 325 horses stampedes towards the horizon. That may not sound like enough horsepower to make you lose your bearings, but by God, it is. Thanks to a stepless intake manifold, double VANOS variable valve timing and other Bavarian black arts, the 3781lbs. luxobarge steams to sixty in a scarcely credible 5.5 seconds. More importantly, it strains to do so at every possible opportunity, to the point where the traction control idiot light sends out a steady stream of Morse Code.
