INTERLAGOS GRAND PRIX
Interlagos, the last race of the year and the end of an era.
From 2014 the technical regulations will be drastically changed with the introduction of new turbocharged engines that will replace the current normally-aspirated V8s. There will also be a reduction in aerodynamic downforce.
All these changes will have a definite effect on the tyres, which have to put down all the forces generated by the car under braking and acceleration, as well as through corners.
Lower downforce means that next year’s cars will have less force pushing them down into the ground than this year. As a result, the cars will have to rely more on mechanical grip from the tyres.
The turbo engines will produce torque in a completely different way to the current engines and the new ERS system will supply extra energy. The result will be a high torque curve transmitted to the tyres that will almost remain constant throughout the rev range.
All these factors mean that extra stress will be put on the tyres – especially the rears – with an increased risk of wheelspin and consequent overheating.
So a brand new challenge awaits Pirelli. For the final appearance of the normally aspirated engines, Pirelli will bring the P Zero Orange hard and P Zero White medium tyres to this particularly demanding track.
