The Renault R26 is an impressive piece of machinery, to say the least. Piloted by Fernando Alonso and Giancarlo Fisichella, the French team's 2006 Formula One race car managed to secure both the titles: the drivers' championship and the constructors'. And it did so under a great deal of stress as Ferrari put up a good fight for both titles, and hardly broke down the entire season.
This video from Renault gives you a look at the car and its engine, all developed and produced in-house, in all their championship-winning splendor.
