Probably because of the dimension requirements of the OEM battery.. Optima has been releasing a few vehicle-specific battery models as of late, so keep your eyes peeled for an exact accplication.
You can use any optima red top 12v that will fit in your car, as they all exceed the OEM cold cranking amp rating and are in every way superior to an OEM battery.
My advice is find a shop that sells them and have them try one for fitment in your engine bay. The standard Optima red top(800U iirc) should fit with a little lovin and tweakin of the battery tray.
