2013 Aston Martin DB9 arrives to confuse you further

What you see here is the new 2013 Aston Martin DB9, a V-12 powered coupe and convertible with 510 hp than can hit 60 mph in 4.6 seconds. No, it's not the Aston Martin Virage -- that one only had 490 hp, although it could hit 60 in 4.6 seconds too. And it's not the V-12 version of the Vanquish, which is slightly ligher and can hit 60 mph in 4.1 seconds using the same engine. If you think Aston Martins have started to look a little simliar, you're not alone.

Despite its role as seller of high-end sports cars to the world's elite, Aston Martin occupies a precarious slot in the auto industry's food chain -- it's a small, currently independent company that doesn't have the resources of a global conglomerate to draw from. That forces a certain amount of remixing, but as of late Aston Martin's desire to fill out its showrooms has left it with a fleet of cars with different names on similar bodywork.

We're all about getting things de-confused, so here's a handy guide the next time you wonder "What Aston Martin model am I thinking of?"

This is the Vantage S V-8. Remember -- no 12-cylinder engine here.

This is the Rapide. It's the easiest to notice -- it's the only four-door model Aston Martin sells.
