Simon Gregg of the seemingly always-on-the-ball-when-it-comes-to-Aston-Martin Car Magazine stumbled upon this production model of the all-new Aston Martin Rapide sport sedan sunning itself in a parking lot without a single trace of camouflage.

The test car you see here is likely one of the final prototype models of the four-door Aston scheduled to be officially revealed to the public at the Frankfurt Motor Show this upcoming September. The undisguised prototype is finished in a menacing black color with a contrasting red interior.

Poised to take on other strangely rear-ended sport sedans such as the Porsche Panamera, the Rapide will be powered by a a 6.0-liter V12 doling out 470 HP and 442 lb-ft of torque.

This Magna Steyr-produced Aston Martin's expected to hit showrooms around the world in early 2010 with a price point expected upwards of $200K.
