'NEXT GENERATION TOURING CAR' GEARS UP FOR 2011

The organisers of the Dunlop MSA British Touring Car Championship, the UK's premier motor racing series, have confirmed more details covering the introduction of new, low-cost technical regulations for 2011 and beyond.

Last year TOCA announced the introduction of the Next Generation Touring Car (NGTC) featuring the use of some common components such as electronics, brakes, gearboxes and suspension to make significant savings to both development and running costs. A new budget-conscious turbo-charged two-litre engine specification was also announced and has already made an excellent competition debut.

Cars conforming to the NGTC specification will be eligible for the BTCC from the start of next season - there will be performance parity with the current S2000 cars until 2013, after which time the performance level of the NGTC car will be further increased.

TOCA has now confirmed that both front and rear wheel drive formats will be permitted under the 2011+ NGTC technical regulations - in accordance with the drivetrain used on the model on which the race car is based. TOCA has also confirmed that the regulations will adopt the use of front and rear sub-frames with double wishbone suspension all-round, as originally envisaged.

GPR Motorsport* has been commissioned to carry out the design, validation, prototype manufacture and testing programme for the new subframe/suspension assemblies. GPR will be the nominated supplier of those suspension subframes and associated assembly components, while TOCA has also appointed the following major control component suppliers as its Technical Partners: Xtrac, AP Racing and Cosworth Electronics.

A full detailed design for both FWD and RWD drivetrain layouts will be carried out using CAD (Computer Aided Design) technology supported by a physical vehicle buck, to validate the component designs and system packaging. A technical working group comprising representatives of the teams, suppliers, GPR and TOCA will regularly meet to provide input throughout the design process.

A prototype NGTC car will be built and undergo a comprehensive track-testing programme to validate and demonstrate the reliability, integrity and performance of the design and assemblies. This car will also take part in the official BTCC practice sessions at the Brands Hatch final round.

At the conclusion of this development/testing process, early October 2010, teams planning to build NGTC for the 2011 BTCC will be provided with all the drawings and data for the mandated component assemblies - thus enabling teams to more easily and effectively design and build their own cars to incorporate those specified components.

Thereafter GPR will be providing on-going technical assistance and will support competitors at all future BTCC rounds and official test days, providing sufficient stock of the suspension components, sub-frames and assemblies - further reducing the need for teams to tie-up their own capital in major parts stock.

"Tremendous progress has been made and we are right on schedule. Its genuinely exciting to see how the car is developing - it will be a fantastic piece of kit!" said Alan Gow, BTCC Series Director.

"At the culmination of the design & development program, our teams will have a comprehensive package of component assemblies around which they can more easily build, individualise and develop their own chosen car. And at around £100k, plus engine, they will then have a better car - which is easier to maintain and has greater performance potential - at about half the cost of a current one. It's a win-win situation for everyone."

"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. Having now had those discussions, I'm confident that there is and so we have now included it."

"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."

Based on the established dimensions and specifications, attached are renditions of a car designed to the BTCC-NGTC regulations.

NGTC - OUTLINE TECHNICAL SPECIFICATION

* Rear sub-frame that attaches to specified roll cage locations. Multi-adjustable double wishbone suspension with coil-over dampers.

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 1875mm
* 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

Target Price:
Complete car, less engine: £100,000*
Engine: £25,000

* 5-10% price-shift possible, depending on final components used by each team

Introduction:

Eligible from 2011. Performance parity will be maintained with current S2000 cars until 2013, after which time the performance level of the NGTC car will be increased.
