British American Racing
Propulsion Universelle et Récupération d'Énergie (PURE; English: "Universal Propulsion and Energy Recovery") was a motorsports engineering company founded by former British American Racing team principal Craig Pollock in 2011. It aimed to design and manufacture engines for use under the Formula One technical regulations, that mandate a switch from the current normally aspirated V8 engines to turbocharged V6 engines. The company was linked to Mecachrome, and employed former members of Renault and Peugeot's 1990s Formula One engine programmes.
