You know that there's a lot of interest in a model when independent designers begin to imagine different versions and body styles of a car that has not yet entered production. Case in point the Alfa Romeo 4C mid-engined sports car that remains in show car form for now but is slated to reach dealerships around the world –including North America- as early as 2013. 
The artists over at Teamspeed created their vision of what an open-top Spider version of 4C would look like. We think that the rendering is pretty much spot on and would make for a very interesting addition to the Alfa 4C's lineup. As for the question to what kind of top would be suitable for a car like the 4C Spider, the answer could be either a simple cloth top or more interestingly, a rotating roof panel similar to the one used on the Ferrari 575 Superamerica and more recently, on the Renault Wind.
Understandably, the 4C Spider would keep the same hardware as the coupe including the 1.75-liter turbocharged four-cylinder petrol engine delivering 200 or more horses to the rear wheels through a twin clutch transmission.
Have a look at the two renderings below and tell us what you think in the comments section.
