More images of Aston Martin’s upcoming four-door Rapide saloon have surfaced, this time depicting the car as it undergoes some cold weather testing. Not much is known about the car apart from the fact that it will be based on Aston’s familiar VH architecture and share similar specifications to the current DB9. This means it will get a 6.0L V12 engine with around 480hp and there could possibly be an entry-level model as well with the 4.3L V8 engine from the Vantage.

Key differences between the production version and the concept include the thicker side mirrors, now mounted on the A-pillar, standard non-LED side indicators, and the conventional door handles. We’ll have to wait until the final production version arrives, late next year, to see how it all pans out.

By the time the new Rapide does arrive, the premium four-door coupe market will be starting to get a little crowded. Some of the cars it will have to compete with include the BMW GT, Porsche Panamera, Audi A7 and the car that started it all, the Mercedes-Benz CLS class.
