Ahead of this weekend's final F1 Grand Prix of the 2013 season Brazil, which will feature the last appearance of Pirelli's current generation of P Zero Orange hard and P Zero White medium tyres to the notoriously demanding Sao Paulo track, the tyre manufacturer has produced a new video briefing discussing the challenges facing them ahead of next year's overhaul of the sport's technical specifications.
The briefing, hosted by Pirelli's racing manager Mario Isola, focuses on the introduction of new turbocharged engines for 2014 that will replace the current normally-aspirated V8s, along with a reduction in aerodynamic downforce. All these changes will inevitably have a knock-on 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. And with turbo engines producing torque in a completely different way to the current engines and the new ERS system supplying energy, the result will be a high torque curve transmitted to the tyres that will almost remain constant throughout the rev range.
See Pirelli explain how 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 that should make the 2014 one of the most wildly unpredictable seasons of F1 in a decade...
