Bentley approached Polar Manufacturing in May 2013 to develop two carbon fibre inner door card concepts for the Continental GTR 3 development project, to assess the use of composite materials.

The project brief was to have one of the door cards produced as a standard door but made using as few individual components as possible. Our brief for the second door was to produce a one piece solution, with both variations maintaining and incorporating the Bentley trademark leather interior. Polar Manufacturing placed a design engineer with Bentley to design both the doors and retrospective tooling. The design and tooling phase took three weeks with parts being fitted to doors in a total of nine weeks.

As a result of the success of the development project in April 2014 Bentley incorporated this carbon fibre standard door card and arm rest into the new Continental GTR 3. In addition Polar manufactured the parcel shelf, rear quarter panels, B-pillars, tread plates, lower lining, rear wing and front splitter for the development, verification and show car which was launched at the Goodwood Festival of Speed in June 2014.
