Reigning Yokohama Independent Trophy champion James Nash and his 2013 teammate Alex MacDowall will not return for the 2014 World Touring Car Championship season.
The pair are understood to be on the verge of announcing separate moves to the FIA World Endurance Championship.
Twenty-eight-year-old Nash secured the Yokohama championship crown driving for the Bamboo Engineering stable in just his second season of WTCC competition, with the highlight being two outright victories in Austria and Portugal.
Teammate MacDowall, 23, finished runner-up to Nash in his sophomore WTCC season.
This year will see Bamboo Engineering enter a pair of new-spec RML-built Chevrolet Cruzes, and the British outfit is expected to announce its 2014 plans shortly.
While an independently operated outfit, the bamboo squad won’t be eligible to compete for Yokohama honours in 2014, as the trophy class is now strictly reserved for the less competitive older-spec entries being run in the TC2 category.
Bamboo’s cars will be pitted against four other RML-built Cruzes (being run by ROAL Motorsport and Campos Racing), as well as the newer-spec designs from Honda, LADA and Citroën, in addition to an as-yet-unconfirmed manufacturer being fielded alongside the Onyx Race Engineering team.
