3. ‘Shark fins’, which are aerodynamic devices extending rearwards from the airbox along the engine cover, improve how airflow is channelled.
4. The minimum weight of the car has increased by 20kg to 722kg to compensate for the heavier new tyres.
5. Brake discs will be up to 4mm thicker this year with braking torque increasing by 25% and a braking force of up to 6g predicted.
6. The maximum height of the rear diffuser has increased from 125mm to 175mm.
7. The rear wing is 150mm lower and 200mm wider than before, with inwardcurving endplates.
8. An increase in aerodynamic parts, and consequently downforce loads, will make the cars between 3sec and 5sec quicker per lap, depending on the circuit.
9. The fuel limit for each race has been increased by 5kg to 105kg, so the cars have larger tanks.
10. The overall track of the cars has increased from 1800mm to 2000mm.
11. Wheels are still 13in in diameter, but they’re 25% wider than last year’s. The front tyres are up from 245mm to 305mm and the rears have grown from 325mm to 405mm. The greater contact area increases grip.
12. The sustained lateral g-force that drivers experience could be up to 5.5g around corners such as Turn Three at the Catalunya circuit. Last year, that was about 3g. Cornering speed will increase by about 25mph.
