Mercedes to make engine decision on Friday

Mercedes will make their decision on whether to introduce their new-spec upgraded engine at the French Grand Prix on Friday.

The original plan for the world champions was to showcase the engine at the Canadian Grand Prix.

However, late reliability issues meant Mercedes had to delay the introduction until this weekend.

Valtteri Bottas revealed to the media, that a final decision on the engine would be made on Friday.

"We need to take some kind of new engine, because the other one is alreadu seven races old," Bottas said.

"We are very much wanting to run the new spec, but we need to confirm tomorrow if we can or not.

"I trust that things have been improved since two weeks ago, and if we decide to run it, it's because we've got full confidence we can run it.

"It is extremely close between the top three teams in every race weekend, so any gain we can make will be very important if we want to win the title.

"For sure we're looking forward to having the new one and that's our plan, so let's hope we can use it."
