McLaren's new partnership with Renault is officially underway after the team fired up its French engine for the first time at its factory in Woking.
McLaren joins Mercedes, Ferrari and Toro Rosso in sharing its fire-up via social media -- a significant moment in the build of any new F1 car. It is arguably even more significant for McLaren this year after the team switched from Honda power to Renault following three uncompetitive seasons with the Japanese manufacturer since the start of 2015.
