History

The Dallara GP3/16 chassis was designed to replace the GP3/13 chassis in the 2016 season. Dallara began the development, design and construction of the GP3/16 chassis in mid-2014. The first chassis began assembly in July 2015, and was completed in September.

Design

Chassis

The Dallara GP3/16 car has a more radical design with the all-new F1-style lower nose, original rear wing, air ventilation in both sidepods and also engine cover. The "shark fin" engine cover was replaced by a more conventional design. The rear wing of all Dallara GP3/16 cars were slightly updated for the 2017 season due to the introduction of the Drag Reduction System (DRS) used in Formula One and Formula 2.[3]

Engine package

The GP3/16 used a 3.4 L (207 cu in) V6 naturally-aspirated direct-injected fuel-efficient engine developed by Mecachrome Motorsport, replacing the P57 engine developed by Advanced Engine Research (AER) that was used in its predecessor, the GP3/13.
