Edit: Was looking through the concet #6 video, and found something that might or might not be a thing. There is a shot of that new Megane Racing thing, which is one of the cars that is "Base model" as well.
In the clip, you see 2 racing close, with what at first looks like different paint jobs, but if you look closer...

In image number 1 (yellow car) we see 'elf' logo stickers on both left and right side, as highlighted, some form up sticker on the front spoiler, highlighted, and a racing stripe down the bonnet, highlighted.
On image number 2 (greyish car) both elf stickers are not on the car, and can't see a sticker on the spoiler (although kinda bad angle). Also can't see evidence of a racing stripe, and clearly on the bonnet we now have a big "renault sport" badge, as well as a RM style number sticker slapped on the top.
Are these just differences between the 3 models of this car? Body kit wise they are identical, so I presumed it was the same car.
