After gaining valuable experience in 2017 with debut performances in both series Olli graduated to a dual ADAC and Italian F4 campaign for 2018.
Rising to the challenge, Olli juggled his GCSEs, along with a jam packed racing calendar. Teaming up with PREMA, Olli took a victory and 4 podiums in the ADAC series, including gracing the podium in front of the watching eye of the Formula 1 paddock, as part of the support series for the German GP.
Tackling the Italian F4 championship, Olli scored 4 victories, 11 podiums and 3 pole positions, to take third in the standings. The highlight of the season came when he claimed a clean sweep at Vallelunga, taking pole position, victory in each race and topped it off with a fastest lap too.
