The FIA has released its latest driver gradings for the 2016 season which features several adjustments.

The system, used by a number of international series and events, grades drivers into four classes Platinum, Gold, Silver and Bronze.

Drivers are evaluated by the FIA before being issued with a grading which is determined by a series of criteria based upon career results.

Among the changes for this year sees V8 Supercar drivers Lee Holdsworth and Chaz Mostert receive gradings having been placed under evaluation when the FIA issued its previous update in December.

The pair have been issued with a silver driver rating which would make them extremely valuable unseeded drivers for teams competing in February’s Bathurst 12 Hour.

Holdsworth is keen to contest this year’s race but says his options are fast running out.

“I wanted to be in something worthwhile and I only really want to go into the race if it something that has a chance of winning,” Holdsworth told Speedcafe.com.

“I’ve had a couple of options but nothing that I am really looking for.

“Most of the best drives are taken and probably all of them to be honest.

“There is one team in particular that is still deciding if it will race or not and if I do it then it would be with them. If not then there is a good chance I will be sitting out this one and I’ll look for something the following year.

“I probably got onto the FIA driver ranking too late but it is good to be rated silver.”

Australian GT drivers Hayden Cooper and Glen Wood have also been issued with a silver grading in the latest update from the FIA.
