Since 2006, the Atlantic Championship has been run exclusively with [[Swift Engineering|Swift]] 016.a chassis powered by Mazda-[[Cosworth]] MZR 2300 cc (2.3L) [[DOHC]] [[inline-4]] engines producing {{Convert|300|bhp|kW|0|abbr=on}}.

[[Formula Mazda]] features open wheel race cars with Mazda engines, adaptable to both oval tracks and road courses, on several levels of competition. Since 1991, the professionally organized [[Pro Mazda Championship]] has been the most popular format for sponsors, spectators, and upward bound drivers. It is the second-highest level on the aforementioned Mazdaspeed driver development ladder. Engines for the Star Mazda series are all built by one engine builder, certified to produce the prescribed power, and sealed to discourage tampering. They are in a relatively mild state of racing tune, so that they are extremely reliable and can go years between motor rebuilds.

[[Spec Miata]] has become one of the most popular and most affordable road racing classes in North America. The Spec Miata (SM) class is intended to provide the opportunity to compete in low-cost, production-based cars with limited modifications, suitable for racing competition. The rules are intentionally designed to be more open than the Showroom Stock class but more restricted than the Improved Touring class.

[[Spec RX-7]] is also a popular club racing class primarily due to the availability of first-generation RX-7 cars and the low startup cost.{{citation needed|date=September 2015}}
