I agree, this figure is meaningless unless we know what part of production this means. It certainly won't be the full cost of producing the car, as implied, let alone supplying it. They have to pay back the R&D, the cost of building the factory, parts, labour, energy, shipping, import taxes, the costs of running the dealer, comission to the dealer, advertising, customer services and warranty costs.
the fact that the raw materials and labour might come to less than 800 doesn't by any stretch mean they will make a profit on every car. Although if they keep the other costs in line then they probably will.
