CAR Magazine reports that this is the genuine article, and that despite a few detail differences, this image reveals that the production version remains mostly faithful to the original concept car.
It loses a few intake vents on the front bumper, and there's a new crease-line from the front guards back, however even the seats remain the same (if you look very closely!). A glass roof also features.
With a 373kW and 570Nm 6.0-litre V12 at the front (essentially the engine from the DBS), the Rapide's estimated two tonnes shouldn't be a problem. ZF's creamy six-speed auto should also promote smooth travelling.
More images will be coming in the next few months, so stay tuned to see the battle between the Aston Martin Rapide and the Porsche Panamera.
