The undisguised Aston Martin’s flagship DB9 was spied at Silverstone last Sunday. The 530bhp supercoupe gives us the best look yet at the DBS’s rear end. Check out the detailed aerodynamics, with an F1-style diffuser and subtle boot spoiler to sucker the coupe to the road. Those tarnished exhausts aren’t the beautifully milled, finished article but otherwise the flagship DB9’s rear end is complete. The new, deeper side sills, which add real muscularity to the design, are also clearly visible.
