Ford pulled the wraps off its 2013 Shelby GT500 coupe at November’s Los Angeles Auto Show, and the big news was that the uber-Mustang would pack a 650 horsepower V-8 beneath its hood.

That’s more grunt than the Camaro ZL1, the Corvette ZR-1 or even the last generation Dodge Viper, which tells us that Ford wants customers to look at the GT500 in a whole new light. We’ll reserve gushing praise for when we get to drive the car, but color us impressed with its specifications, at least on paper.

Missing from the Los Angeles Auto Show was a topless version of the upcoming GT500. It seems like a must-build for Ford, since Chevy already showed a Camaro ZL1 convertible and it seems logical to expect a drop-top next-generation Viper, too.

If Topspeed is correct, we’ll see the 2013 Ford Mustang Shelby GT500 convertible make its debut at next month’s Detroit Auto Show. Expect the same design themes applied to the coupe to carry over, including new wheels and a restyled front end.

There’s no word yet on pricing or availability, but expect the launch of the convertible to follow the launch of the coupe. We’ll keep you updated on the 2013 Ford Mustang Shelby GT500 convertible as part of our comprehensive 2012 Detroit Auto Show coverage.
