Lewis Williamson fills final GP3 seat at Bamboo

Williamson has tested for the squad, which replaced Atech CRS in the series when it expanded into single-seaters alongside its World Touring Car Championship programme, throughout the winter and been a regular pacesetter.

"I've been involved in testing with Bamboo for all the sessions both in and out of the car and am relieved to be on the grid this season, plus it's exciting signing at the last minute," said Williamson.

The 23-year-old Scot was a GP3 frontrunner with MW Arden in 2011.

He moved up to the team's Formula Renault 3.5 arm with Red Bull support the following year, but lost his place on the drinks firm's young driver scheme halfway through the season.

Williamson subsequently returned to GP3 with Status.

Bamboo team boss Richard Coleman expects Williamson to prove his squad is a match for its more established rivals.

"It will be great to see Lewis show the true potential of the Bamboo Engineering GP3 car and put us up there in our first season," said Coleman.

Williamson joins Carmen Jorda and Melville McKee in the Bamboo line-up.
