All cars have been built to the same NGTC regulations. These technical regulations are designed to dramatically reduce the design, build and running costs of the cars and engines.
NGTC allows independent teams to compete on a level playing field against manufacturer-backed efforts by keeping costs down whilst at the same time rewarding precise engineering and all-important split-second strategy.
The foundation for NGTC is an emphasis on some common components – turbo, wastegate, intercoolers, ECU (engine control unit), instrumentation and dash, power management system, six-speed sequential gearbox, fuel tanks, differential, subframe, steering, brakes, clutch, wheels, dampers and suspension – which dramatically drives down costs for teams looking to compete in one of the world’s most attractive motor sport arenas.
Teams have the option of running either TOCA’s unbranded NGTC-spec engine or, whether privateer or full manufacturer-backed entries, developing their own powerplant to the regulations, as long as it is from the same ‘family’ as their chosen model of car – all are 350+bhp 2-litre turbo-charged engines
An overview of the Technical Specifications are below:
Engine:
- 350+bhp 2-litre turbo-charged direct-injection engine with ‘fly by wire’ throttle control
- Low cost to develop, build, buy and maintain – either by teams and/or race engine-builders developing their own, or through lease/purchase of the TOCA/M-Sport prepared engine
- Engine can be sourced from a manufacturer’s broad ‘family’ range, including subsidiary marques under their effective control
- Common Owen Developments turbocharger & wastegate and PWR intercooler to be used by all cars
Drivetrain:
- Xtrac 6 speed sequential-shift gearbox and differential
- AP Racing carbon clutch with steel cover
- Drive-train layout (i.e. front or rear wheel drive) as per base vehicle
- 4WD base car keeps engine orientation as production which defines driven wheels
Suspension:
- RML designed full front sub-frame incorporating suspension, brakes, transmission and engine location that attaches to specified roll cage locations. Multi-adjustable double wishbone suspension with GXC supplied Penske coil-over dampers
- RML designed rear sub-frame that attaches to specified roll cage locations. Multi-adjustable double wishbone suspension with GXC supplied Penske coil-over dampers
- Hydraulic Power Steering
Bodyshell:
- 2, 3, 4 or 5 door of a minimum 4.4m length (2 or 3 door cars must share the same basic body profile as the 4/5 door model)
- Equalised width of 1890mm
- Specified front aerodynamic device incorporating flat floor, apertures for radiator, brake cooling ducts, intercooler and side exits
- Specified rear wing profile
- Stylised front & rear wheel-arch extensions
- Increased driver protection
- Latest specification FIA Homologated seat
- Side exhaust permitted
- 80 litre ATL fuel tank
- Lifeline fire extinguisher system
- Base vehicle must be freely on sale in the UK through the manufacturer’s normal dealer network at time of homologation
- Equalised base vehicle weights, for front and rear-wheel drive – 1280 kilos
Wheels/Tyres:
- Specified DYN Automotive 18” centre-lock wheel
- Goodyear: Hard, Medium, Soft and Wet compounds
Brakes:
- AP Racing specified package
- AP Racing specified pedal-box
Electronics:
- The entire vehicle control system has been packaged into one unit. This means the control of all elements surrounding the internal combustion engine and all chassis elements, including the TOCA Turbo Boost (TTB), are managed by the Cosworth Antares 8 ECU (Electronics Control Unit)
- Common power management box, switch panels & firefly light panels
- Common Cosworth wiring loom design
- Judicial camera system to be run by all cars
Sustainable Fuel:
- From 2025 the BTCC will use 100% fossil-free sustainable fuel
