I just copy/pasted from TamiyaUSA.com, but looks like a hopped up F104W with all the bells and whistles. Pretty much what people were speculating.
The standard F104W chassis is equipped with F103 front suspension arms to allow it to accurately replicate the dimensions of classic F1 race cars of the 1980�s and early 1990�s. This limited edition F104W GP Edition chassis features many additional race-spec parts to enhance the performance of this variant even further.
