Hulkenberg gets grid penalty in Baku

The German driver sat out the final quarter of Saturday's practice session after reporting a problem.

Renault immediately decided to change the gearbox ahead of qualifying, which means the component has not lasted the six consecutive grands prix required by the regulations.

Hulkenberg, who has started the last six races from seventh place, will therefore take a five-place grid penalty.

His early exit from FP3 left him 17th in the times, one place behind team-mate Carlos Sainz Jr.

It continues a tricky start to the Baku weekend for Hulkenberg, who missed out on FP2 running while Renault changed the plank under his floor and also suffered minor brake problems.

"In FP2 I generally wasn't happy with how they felt or how they performed but that can happen sometimes," he said.

"They were also used brakes, which probably explains the biggest part of it."
