The Ford Taurus SHO is back, and here's further proof. These photos show the 2010 Ford Taurus SHO, which we expect to see revealed next month in Chicago, doing some humid weather testing in Florida.

We have to thank TampaRon for snagging these photos of this pair of mostly uncovered SHO prototypes taking a breather at a Florida rest stop. According to Ron, the testy test engineers wouldn't let him close enough to snag some shots of the interior but he managed to get close enough to see the SHO badge (a la this shot) on this ecoboosted Taurus.

The undisguised exterior doesn't leave much to the imagination — especially since we've already seen the 2010 Ford Taurus live and in person. In fact, the only difference in design between the SHO and non-SHO Taurus appears to be the badge on the back and the separated double pipes.

We've already seen the Taurus SHO interior, so the only question is pricing, availability and what's under the hood. Oh wait, we know what's under the hood. Based on what we learned from the leaked Taurus ordering guide and other sources, the new SHO will likely get the EcoBoost V6 engine, which is good for 355 HP and 350 lb-ft of torque in its 2010 Lincoln MKS platform-mate.
