TOCA reveals final NGTC specifications
BTCC organiser TOCA has revealed the final version of the NGTC (Next Generation Touring Car) regulations. The major change is that rear wheel driven cars are permitted.
“After we released details of the NGTC program last year, I stated that we would revisit the question of incorporating rear-wheel drive in the regulations if there was enough interest or commitment from teams and manufacturers of rear-wheel drive cars to support it,” said BTCC boss Alan Gow.
“Having now had those discussions, I’m confident that there is and so we have now included it.”
A prototype version of the NGTC car is going to be developed during the later stages of this year and will be showed during the season finale at Brands Hatch.
“Tremendous progress has been made and we are right on schedule. It is genuinely exciting to see how the car is developing – it will be a fantastic piece of kit!” Gow added.
A complete car, excluding engine, is going to cost about 114 000 € and GPR Motorsport has been appointed to design and manufacture the prototype front and rear subframes. Xtrac and Cosworth are going to provide the gearboxes and electronics while AP will supply the brakes.
All of these unit type parts are going to be introduced to reduce the costs compared to the cars of today.
“As these NGTC technical regulations provide a much more cost-effective opportunity for teams to compete in Britain’s biggest motor-racing championship, I’ve no doubt that the BTCC ambitions of many new drivers and teams will now be realised,” said Gow.
The prototype car is going to take part in the practice sessions of the BTCC finale at Brands Hatch later this year.
