The next Russian grand prix could be a night race.
According to the Dutch newspaper De Telegraaf, new F1 venue Sochi Autodrom’s contract with Bernie Ecclestone is for at least seven years.
On Sunday for the inaugural race, the start-time is at 3pm local.
But next year it could be much later.
"We want to start at dusk and finish in the dark," the newspaper quoted boss Richard Cregan as saying.
"The infrastructure for the lighting is already present, we are now waiting for the green light," he added.
Bernie Ecclestone is said to have already basically agreed to the proposal.
