British Touring Car Championship organisers TOCA has awarded a five-year contract to supply new NGTC-specification engines to Swindon Engines, beating eight other entrants from the initial application.

Since the introduction of the NGTC regulations in 2011, it is required that a cost competitive engine is available to all teams in BTCC, which had been supplied by Swindon Engines for the past four seasons. The initial agreement runs until next year and the new contract announced will maintain the manufacturer's involvement up to 2021.

The latest tender was scheduled as part of mid-term review on the NGTC regulations. RML Group had recently been announced as BTCC's new technical partner after taking over from GPRM from 2016 onwards.

TOCA has revealed nine engine manufacturers entered the tender process which ended in a clear majority decision made by a Review Panel - consisting of TOCA and nine BTCC teams - to award the new contract to Swindon Engines.

The new specification engine will continue through a final development programme ahead of its introduction in 2017.

"I would like to congratulate Swindon Engines on the award of this new contract to supply the new 'TOCA' engine until 2021," BTCC series director Alan Gow said. "Swindon Engines tender and presentation was of the highest calibre.

"Swindon Engines has the proven record of supplying engines on a wide scale in the BTCC, having successfully supplied the 'TOCA' engine to the Championship since the outset of the NGTC regulations.

"Over the last five years TOCA, Swindon Engines and the BTCC teams have worked closely together on developing what was already a very impressive product, and we look forward to continuing with this philosophy into the next decade."

Raphael Caille, Swindon Engines managing director says his company is delighted to secure its working partnership with the BTCC and is hoping to continue the developments made from the first four years.

"We are extremely proud to be able to continue our long-standing partnership with the BTCC, the UK's highest profile motor sport series," Caille said. "We have continued to develop our one-fits-all product over the last five years and provide a high performing, reliable and consistent unit, which benefits teams throughout the grid.

"Our engine remains cost efficient whilst not compromising on performance, as proven so often by the numerous race winners in the BTCC."
