Toto Wolff backs new Formula 1 engines

Mercedes boss Toto Wolff has claimed that car manufacturers in Formula 1 are committed to running turbo hybrid engines.

Red Bull principal Christian Horner has called for the constructors to stop using V6 power units on the basis that they are too costly.

However, Wolff has suggested that engine makers are in agreement regarding the type of engines that should be used in Grand Prix racing.

Wolff is quoted by BBC Sport as saying: "Mercedes, Renault, Ferrari and Honda are aligned on the power-unit specifications - a V6 turbo hybrid as per the current rules.

"We all agree development of the internal combustion engine and hybrid system will remain a part of the rules.

"If we want to adapt the engine regulations, we will discuss that. It's nice to hear the views of individual teams as part of that discussion but they do not reflect the views of the manufacturers."

Mercedes finished 306 points ahead of nearest rivals Red Bull in this season's constructors' championship.
