2018 ADAC Formula 4 Championship

The 2018 ADAC Formula 4 Championship was the fourth season of the ADAC Formula 4, an open-wheel motor racing series. It was a multi-event motor racing championship that featured drivers competing in 1.4 litre Tatuus-Abarth single seat race cars that conformed to the technical regulations for the championship. It began on 14 April at Oschersleben and finished on 23 September at Hockenheim after seven triple header rounds.

The championship was dominated by US Racing – CHRS driver Lirim Zendeli, who secured the title after race three at the Nürburgring. He extended his wins tally to ten with victory in the season finale at Hockenheim. His success was key for US Racing – CHRS teams' title. Van Amersfoort Racing driver Liam Lawson lost to Zendeli by 114 points with wins at Lausitzring and Spielberg. Prema Theodore Racing driver Enzo Fittipaldi was third with just one win, at Spielberg. Lawson's teammates Frederik Vesti and Charles Weerts were victorious at Hockenheim and Nürburgring, completing the top five in the standings. David Schumacher won the rookie title, defeating fellow German driver Niklas Krütten by 31 points.
