Thats no concept; I mean it can be a conceptual form of a body-kit for the Volvo P1800 from some Auto-Body shop. You can't compare it to the Furai!!
Probably this car would enter production like Callaway, Gemballa, Alpina, etc...its an after-market modification to the original P1800!! Whereas the Furai is 'new' concept platform or Design language for future Mazda vehicles.
