F1: Lotus confirms Mercedes engine switch

The Lotus Formula 1 team has confirmed it will drop Renault power to run Mercedes engines next season.

The squad agreed a long-term engine deal with Mercedes in July, but had to finalize details of its split from Renault before confirming the switch. Renault is planning to focus more on its works partnership with Red Bull for 2015, after a disappointing first season under the new V6 hybrid turbo regulations.

Lotus will replace McLaren as Mercedes' third customer team next season, as that team enters a new works partnership with Honda.

Lotus will also use Petronas fuel – dropping Total – and lubricants as part of the deal, but will continue to manufacturer its own gearboxes.

Lotus CEO Matthew Carter said he hoped the move would return his team back to the front of the grid, after a difficult 2014 campaign.

"It is our desire that the E23 Hybrid, powered by Mercedes, heralds a new era of success for Enstone," he said. "At this juncture we would also like to thank Renault, who have been so closely associated with the team over its history and for the joint success we have achieved together."

Mercedes engine boss Andy Cowell added: "Lotus is a strong technical group with excellent facilities and I am confident that together we will deliver a step forward in track performance next year."
