Any Idea Which Detroit Motor Show Debut is Teased Here?

After last night's pop quiz, the guessing game on which Detroit Motor Show debut is previewed through an unnamed picture continues with the cropped shot you see above.

Once again, it comes to us from spy shooter Chris Doane, who won't share the name of the world premiere, leaving us to find out which one it could be.

The chrome trim accent on the lower portion of the bumper eliminates any sport or regular sedan entry, while the fog lights look like what you expect to see on a production car.

If you want us to be more specific, we're thinking it's an SUV or a pickup truck, but go ahead and tell us what you believe it is in the comments area.

Pop Quiz: Which Detroit Motor Show Debut is Hidden Behind this New Teaser Photo?

While we've done our best to keep you fully updated and…visually informed about all the world premieres (and the North American debuts, but those don't really matter, do they now) set to take place at the Detroit motor show on Monday, some production cars and concepts have eluded us.

That doesn't mean they will all remain hidden from plain sight until Monday, or at least not in their entirety, as this cropped teaser photo that was just released by automotive spy Chris Doane proves.

We're guessing that the rear diffuser shot comes from a surprise premiere or a car that has been announced but not shown yet, and we have plenty of those, including the Corvette Stingray Z06, Ford F-150, GMC Canyon, Acura TLX and the Toyota Mirai sports concept.

So, what do you think it is?

Scoop: Which New Renault Model is Hidden Under This Test Mule?

One of the best ways for automakers to conceal upcoming products during testing on public roads is to use so-called development or test mules that hide a new or modified chassis and drivetrain components under a fake body shell, typically sourced from a model currently in production.

This is the case with a new Renault prototype captured by our spy photographers this week in Northern Europe undergoing cold weather testing.

The modified body shell is borrowed from the facelifted Renault Fluence, but it's evident from the photos that the car is sitting on a longer wheelbase and wider platform. It also rides on a taller suspension.

At this point, however, we are not aware if the French brand is working on a new SUV / Crossover or a sedan / station wagon model, but the upcoming Geneva Motor Show in March of 2014 may provide some answers to what's concealed under the sheetmetal.
