Though the championship remained faithful to its philosophy of making eligible production cards modified for racing, the changes – which will mainly affect the chassis and body – could lead to improvements of 1.5 seconds per kilometre.
The 1.6-litre engines, introduced three years ago, will continue to power the cars but larger restrictors will increase maximum output by more than 15 per cent.
The suspension scheme is no longer linked to the production’s model, but is specifically designed for racing while the aerodynamic package includes wider fenders, a proper front splitter, a flat bottom and a larger adjustable rear wing.
Larger 18” wheels, instead of the current set of 17”, cap a huge step forward that should signal a better racing look and a drastic increase in performance on the track.
The cars complying with the 2014 Technical Regulations have been classified as TC1, while the 1.6-litre machines that competed between 2011 and 2013 will form the TC2 class.
The older 2-litre normally aspirated cars will no longer be eligible.
