Although F1 was never on the long circuit, it was once in the Bugatti Circuit which uses part of the long track and it can be seen in the layout presented on the right side. I will present a Le Mans Video later in the year but for now, we have this onboard on a Matra driven in practice by Henri Pescarolo.
This engine was the base for the future F1 Matra engine. Note that its has a higher note than most engines of that era. Enjoy!
