British Touring Car supremo Alan Gow believes the new NGTC regulations have made it possible for MG to return to the series.
MG has announced it is returning to the category with a works assault run by ex-Vauxhall factory team Triple Eight Race Engineering, with double champion Jason Plato and Andy Neate on the driving strength.
Gow introduced the NGTC rules ahead of the 2011 season in an effort to cut costs and attract more teams to the BTCC. He believes NGTC was key in MG's decision.
"There's no doubt that MG wouldn't have been able to do this with the previous [S2000] regs and expensive homologation," said Gow.
"It's great news for the series. To have the MG marque in the BTCC is fantastic for us, and the BTCC will help MG's marketing and promotion.
"It's a win-win situation. It underlines not only the value of the series, but also the value of the regulations and media coverage."
Gow also welcomed the move back towards a factory programme for Triple Eight, which has run as an independent since the termination of Vauxhall's effort at the end of 2009.
"Triple Eight have been an important part of the fabric of the championship," he added. "It's great to see them here with a new challenge."
