Upon the conclusion of the Formula BMW season, van Asseldonk moved into another series; he joined the Prema Junior team in the newly renamed Formula Abarth championship, for the final three races of the 2010 season. He joined the series at Vallelunga, and qualified fourth for his opening race. Van Asseldonk hit form in the series straight away, and ultimately took the first victory of his career, ahead of drivers who had taken part in the full season up to that point; he followed this up with a fifth place in the reverse-grid second race, having failed to advance up the order, after starting in the same position.
