Mazda makes both piston and Wankel "rotary" engines. This page summarizes the various engine families and variations.

Piston engines

Even though Mazda is better known for their Wankel "rotary" engines, the company has been manufacturing piston engines since the earliest years of the Toyo Kogyo company. Early on, they produced overhead cams, aluminum blocks, and an innovative block containing both the engine and transmission in one unit. This section summarizes piston engine developments. Note that Mazda has produced many piston engines, but only V-twin, straight-4, and V6 configurations.

V-twin

Like other Japanese makers, Mazda produced a short-lived line of V-twin engines for their tiny keicars of the 1960s. These were essentially motorcycle engines, and were superseded by water-cooled straight-4 engines in less than five years.

• V-twin - Half-liter air-cooled V2 (1961-1963)

Straight-4

Mazda's strength since the 1960s has been in its line of straight-4 engines. Beginning with a tiny 358 cc keicar engine, one of the smallest ever made, Mazda continues to this day to be a leading developer of this type of engine. Today's MZR family has become one of the most common four cylinder powerplants in the industry, powering Ford and Mazda cars.

• OHV engines - 300 cc–1.2 L OHV I4 (1961–1974)
• xC engines - 1.0 L–1.8 L SOHC I4 (1965–1983)
• E family - 1.1 L–1.5 L SOHC I4 (1980–1986)
• F family - 1.8 L–2.2 L SOHC/DOHC I4 (1977–2002)
• G family - 2.5 L–2.6 L I4 (1989–1999)
• B family - 1.3 L–1.8 L SOHC/DOHC I4 (1987–present)
• Z/MZ family - 1.25 L–2.3 L DOHC I4 (1995–present)
  • MZI - Ford Zetec SE
  • MZ-CD - Ford/PSA Duratorq
• Keicar engines - Suzuki-made I4
• Diesel - 1.4 L–4.6 L I4
• YF - 2.0 L I4 for Mazda Tribute

V6

Mazda has created three families of in-house V6 engines. Today, however, their primary engine is a Ford design.

• J family - 2.0 L–3.0 L 90° V6 (–1995)
• K family - 1.8 L–2.5 L 60° V6
• Diesel - 4.1 L–5.5 L ZB/ZC V6
• AJ/MZI - 2.5 L and 3.0 L V6 - The Mazda version of the Ford Duratec DOHC V6. The 3.5 L MZI is the new Ford Cyclone engine.

Wankel engines

Mazda is the only producer of successful Wankel engines, positioning them as a prime sports car powerplant. All of Mazda's Wankels are based on their first design of the 1960s, though there have been significant developments over the four decades since.

• Wankel family - 1.0 L-2.0 L Wankel (1967–present)
  • 10A - 1.0 L (1967–1973)
  • 10B - 1.0 L (1968–1972)
  • 13A - 1.3 L (1970–1972)
  • 12A - 1.1 L (1970–1985)
  • 13B - 1.3 L (1973–2002)
  • 20B - 2.0 L three-rotor (1990–1996)
  • RENESIS - 1.3 L (2004–)

SKY engines

The SKY family of engines represents the next-generation of Mazda engines. First unveiled at the 2009 Tokyo Motor Show, it comes in Direct-Injected Petrol and Diesel variants.

• Mazda SKY-G engine
• Mazda SKY-D engine
