Mitch Evans produced a fine performance to claim his maiden victory in the GP3 Series at Barcelona. The 16-year-old New Zealander's win was also the first in the category for his MW Arden team.
Starting from pole, Evans held onto first place, with fellow front-row starter Andrea Caldarelli having to defend his position from Tech 1 teammate Aaro Vainio. James Calado took advantage of the pair's battle to move into second place, with Vainio also getting past Caldarelli.
Evans' lead remained a comfortable one for the whole of the race, crossing the finish line 1.885 seconds ahead of Calado. Caldarelli attempted to take third place back from Vainio but was not able to do so and had to settle for fourth behind the Finn.
Nico Muller finished just behind the pair in fifth, having passed Nigel Melker at the start of the race. Melker came across the line in sixth, with Dean Smith and Tamas Pal Kiss rounding out the top eighth. The Hungarian made it all three Tech 1 cars in the top eight and claimed pole position for Race 2 as well.
