"Yes we will be using KERS next year," Symonds explained. "We plan to adopt the system that has been developed by Williams, which was used by them with the Cosworth engine last year and is currently with their Renault-engine car.
"Our 2013 unit is a development of this. We've been very impressed with the engineering, the efficiency and the weight. Williams are also a pleasure to work with both technically and commercially."
He also revealed that Marussia F1 will continue to use Cosworth engines next year, with both parties more than happy to continue their working relationship.
"We will continue with the Cosworth engine. We are happy with the work we are doing with them and I think that we are working together to try and improve the areas that we are able to under the regulations. We are concentrating on improving the driveability of the engine and enhancing its performance as a unit with the car," Symonds added.
