The 2017 season ended with Formula 1's two support series crowning dominant winners. But a glance at the results sheets won't provide the full picture of a year of ups-and-downs, thrills and spills, and two entertaining Formula 2 and GP3 championships.
In F2, Ferrari junior Charles Leclerc ignited an astonishing run to a rookie title (the first in the Pirelli era) with a charge through the field in the Bahrain sprint race, which set the tone for his dramatic year. He capped it with a Sauber F1 seat and another sprint race surge in Abu Dhabi that left Lewis Hamilton wondering why F1 can't produce racing as good as the support categories.
George Russell swapped the European Formula 3 championship for GP3 ahead of 2017, and the Mercedes-backed driver headed another season of domination for ART Grand Prix, which filled positions 1-2-3-4 in the championship. Russell, Jack Aitken, Nirei Fukuzumi and Anthoine Hubert slugged it out on track without falling out and gave the French squad a seventh GP3 title in eight seasons.
