Actually that is a Rallycross Fiesta, which yes, is even further from our rides than the actual WRC Fiestas are, since the WRC cars, even the Rally 1 versions (when they still used them and not the current Puma platform) must be by the rules, and ARE based on the base Fiesta factory platform.
The rules of Rallycross allow them to use (and they DO use) a north-south engine layout in the engine bay, whereas the WRC cars MUST use our east-west layout.
The WRC cars (in ALL classes) must have a steel roof, HOOD (believe it or not!), and maybe the rear hatch, all other body panels can be crunchy carbon fiber/kevlar composites.
But YES, regardless of WRC Rally 1 class, or Rallycross, their suspensions/drivetrains/suspension geometries are radically different than our cars.
