Sebastien Loeb Racing has bolstered its entries for the 2016 World Touring Car Championship to become a three car attack as Gregoire Demoustier joins the already announced Mehdi Bennani.

The French driver endured a steep learning curve in his rookie year in WTCC after finishing 20th in the overall standings and seventh in the Yokohama Independent Drivers' Trophy for Craft Bamboo in the unfancied Chevrolet RML Cruze TC1.

Demoustier will contest the full 2016 WTCC season alongside Moroccan driver Bennani for Sebastien Loeb Racing, while Loeb himself has recently split from the factory Citroen squad which had initially thrown his commitment in the championship into doubt.

SLR has since confirmed it will still line-up on the grid as an independent entry with Citroen C-Elysee WTCC machines but Loeb's level of participation is still unknown, with the nine-time WRC champion set to take on the Dakar Rally with Peugeot next year.

Demoustier, who switched from GT Racing to WTCC at the start of 2015, says he is thrilled to secure a drive with SLR and Citroen.

"I'm glad to be joining S?bastien Loeb Racing, actually I couldn't have hoped for a better team to recruit me," Demoustier said. "I'm happy to compete with a French squad especially with the operational expertise they've been showing with the Citro?n C-Elys?e. Mehdi Bennani had an excellent season and there's no secret to it: that certainly wasn't down to luck but rather to great work.

"I've learned a lot during this first year whether in terms of my skills on board a front-wheel drive or as regards to the championship itself. My goals will be different next year. I'll be more ambitious and I hope to achieve some great results in the independent drivers' classification. The C-Elys?e is a very competitive car and I'm curious to drive it and see how it behaves. I'm quite confident and hopeful."
