I would assume that being this is a sports car it has a high performance engine. Thus, yes it probably requires a higher octane gasoline. The best way to find out, is to look at the owner's manual. It will tell you there exactly what you need to use. If the owner's manual is unavailable call your local dealer. They will either have the answer, or will have access to an owner's manual. In response to other answers, lower octane gas will have negative effects on your engine if it calls for higher octane gas. High performance engines have higher compression ratios, and therefore needs a fuel that can withstand the higher pressure without igniting prematurely from this higher pressure.
