In the 2017 season all teams once again will rely on the know-how of the experienced Italian chassis manufacturer Dallara. The minimum weight of the vehicle including the driver in full racing gear and all the fluids apart from the fuel – amounts to 580 kilograms. The car’s width including the tyres must not exceed 1,850 mm and the minimum wheelbase amounts to 2,000 mm.
For 2017, the proven F312 chassis receive significant upgrades to enhance performance and safety as well as expand their homologation until the end of 2019. The nose has been lowered and the impact structures have been updated in accordance with FIA safety standards. Additional Zylon panels will protect the survival cell from side impacts and wheel tethers sustain 50% more force. At the same time, new, three-dimensional front wing endplates, an updated rear wing profile and a larger diffusor will boost aerodynamic grip of the cars this season, making them very likely the fastest ever Formula 3 racecars.
With their stepped under-floor, a crash box at both ends as well as two roll-structures, the vehicles are extremely safe. In addition, they have had to pass the strict FIA crash tests for homologation. Still, the drivers should not overdo it: Even in the case of a crash resulting in a massively damaged chassis, replacing the chassis during the course of an event is prohibited.
The gear shifts are executed with a longitudinally mounted sequential six-speed gearbox. Shifting events are electropneumatically controlled and activated by paddles on the steering wheel.
Only the use of RAVENOL F3 Gear premium oil is permitted.
After 2014 marked the beginning of a new era for Formula 3, four-cylinder engines with a maximum cubic capacity of 2,000 cc and direct fuel injection may be used again this year. Series production is not stipulated. Engines must be normally aspirated. The horsepower output is limited by a 28 mm air restrictor (26 mm until 2013).
The FIA Formula 3 European Championship single-seaters are exclusively shod with Hankook Ventus tyres (180/550 R13 front, 240/570 R13 rear).
The safety tanks made of rubber solely are fuelled with 102-octane fuel. Re-fuelling is prohibited during both the practice sessions and the races. ARAL will provide the fuel for all DTM events.
For 2017 the car has been updated with advanced aerodynamics consisting of a more efficient rear wing profile, a larger diffusor and wider front wing and 3D shaped front wing end plates.
Improved safety features with a lowered nose and an updated front impact structure.
