It's definitely confused me. According to ewrc it's certainly never rallied competitively before. Looking at the numberplate it's sort of between the '16 and '17 cars, so I wonder whether this was the initial mule car maybe when they started testing? It's got 2017 headlights and rear wing but not much else.
