This year marks a step change in the F1 regulations. A raft of aero and powertrain rules are set to create a more efficient race car with more direct links to road car technologies. V8s, used since 2006, will be replaced by all new 1.6 litre turbo charged V6. Engines are now also referred to as 'power units' thanks to the increased hybrid nature of their power generation. As track testing of this new 'turbo' and what some describe as an 'energy efficient' era, one supplier to the F1 teams talks about the impact of the rules on its business and how it is responding to the challenges. In this interview, Matthew Beecham spoke to Terry Graham, managing director of Zircotec, a supplier of thermal management products and heat protective coatings.
