Ex-Williams director Patrick Head says F1 engines are 'too expensive'

Patrick Head, the former director of engineering for Williams, believes that the new hybrid F1 engines are "far too expensive".

Head was the co-founder of the Williams Formula 1 team in the 1970s but resigned as director of engineering in 2012. However, he continues to work with Williams Hybrid Power Limited.

Speaking to Tom Clarkson, Head says that Formula 1 should be more about the drivers and entertainment than demonstrating the benefits of hybrid technology.
