According to what, other than you? The guidelines say nothing about adding the word "concept".
Please stop mini-modding everyone's threads too, if a mod spots an error in the title, they'll correct it. It's becoming extremely tiresome. Concentrate instead on the numerous errors you often make in your own threads.
I think "vision" pretty much means concept in many cases with cars, so I see nothing wrong with this. Anyway it's a weird looking thing, like if a nissan IDX and a bmw m4 mated with a SLR Stirling moss
