Heavier Pirelli tyres force F1 car weight increase 23 January, 2014 The mandatory minimum weight of Formula 1 cars will be raised by 1 kilogram for 2014, according to reports in Italy. That is because Pirelli, having controversially grappled with failures throughout last season, has advised that their new tyres need more reinforcing kevlar to cope with the higher torque of this year’s new turbo V6 engines. The report caused the rule tweak, raising the minimum weight to 691kg, to be promptly ratified by the World Motor Sport Council. Omnicorse also claims that Caterham has followed McLaren and Ferrari‘s lead in designing its 2014 car around innovative pull-rod front suspension. (GMM) Subbed by AJN.
