Currently, Formula Ford racing exists in two main forms in Europe: National Series for aspiring 'career' drivers run around the world which have used the 1600 Duratec engine, (which replaced the heavier but not significantly more powerful Zetec engine in 2006), and for 2012 are beginning to adopt the new EcoBoost 1600 turbo engine; and a mainly amateur, club-racing series attracting serious enthusiasts using the now rejuvenated 1600 Kent engine with which the formula ran from the mid-1960s to mid-1990s, as Ford restarted production of the Kent engine in 2009 for motorsport reasons. Whatever the engine of the Formula Ford car, it has long provided a relatively inexpensive way for drivers to race purpose-built racecars. There are many Formula Ford 1600 series for drivers of the older Kent-powered cars.
