2017 GP3 Series

The 2017 GP3 Series will be the eighth season of the GP3 Series, a motor racing feeder series that runs in support of the 2017 FIA Formula One World Championship and sister series Formula 2. The series will introduce the use of the drag reduction system (DRS), an overtaking aid that cancels out aerodynamic drag and allowing drivers to achieve a higher top speed when within one second of the car in front at designated points on the circuit.

ART Grand Prix, who achieved their sixth teams' title in the first race at Monza in 2016, will start the season as the defending teams' champions.

On 27 January 2017, the full calendar was revealed with eight rounds taking place.
