In the 2015 season all the teams once again will rely on the know-how of experienced Italian chassis manufacturer Dallara. The chassis used are the ones of the 2012 specification that have been homologated for Formula 3 up to and including 2017. With their stepped under-floor, a crash box at both the front and the rear 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 minimum weight of the vehicle – including the driver in full racing gear and all the fluids apart from the fuel – amounts to 565 kilograms. The car width including the tyres must not exceed 1,850 mm and the minimum wheelbase amounts to 2,000 mm.
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.
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.
