specification

‘Parc ferme’ is a rule that effectively specifies a time beyond which the set-up and specification of the car are fixed.

Russell is using an older specification because he damaged his new parts with his qualifying crash.

The specification was created by the Green Software Foundation, whose more than 60 members include Microsoft, Intel and Google.

Russell recovered to sixth place in the race after starting from the pit lane driving a car rebuilt to a previous specification.

"The contractors, it seems, felt that they couldn't deliver the building to the specification for the money that was available. That's our interpretation of what happened," he said.
