The opening day of competition at Lousada dramatically reshaped the picture across all four European categories. Johan Kristoffersson and Armin Raag took major steps towards the RX1 and RX5 titles, while Filip Melon completely reignited the RX4 championship battle. In RX3, the elimination of both Julien Meunier and Rytis Gurklys ensured the title fight will go down to Sunday.
