This is a list of piston engines developed, independently or with other car companies, by Toyota Motor Corporation.
Toyota has produced a wide variety of automobile engines, including three-cylinder, four-cylinder, V6 and V8 engines. The company follows a naming system for their engines:
Suffix | Feature |
---|---|
A | Valvematic variable lift intake head |
B | Before 2000 indicates twin SU-style side-draft carburetors After 2000 indicates E85 Ethanol fuel.[ citation needed ] |
C | Carbureted/California Emissions Controlled |
D | Twin downdraft carburetors or Toyota engines manufactured by Daihatsu without VVT-i (e.g., 1KR-DE) |
E | Multi-point fuel injection |
F | Normal cylinder head DOHC |
G | Performance cylinder head DOHC |
H | High compression High pressure charged (e.g., 2L-THE) |
I | Single-point fuel injection |
J | Autochoke (early models) or pollution control for commercial cars in Japan |
K | On-demand Atkinson cycle in non-hybrid engines |
L | Transverse |
M | Philippines' market (meaning unknown) |
N | CNG fuel |
P | LPG fuel |
R | Low Compression (For 87 and below octane fuel) |
S | Swirl intake (1980s) D-4S gasoline direct injection |
T | Turbocharged |
U | With catalytic converter Japan-spec emissions |
V | D-4D diesel common rail direct injection system Toyota engines manufactured by Daihatsu with VVT-i (e.g., 1NR-VE) |
X | Hybrid Atkinson cycle |
Z | Supercharged |
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE.
Examples:
The use of "G" to denote twin cam engines was decided on in 1971, with the renaming of the 10R into 8R-G. Before that, twin cams had received separate numerical codes. [1]
In 1987, Toyota began assigning dual letter engine codes to some of the "engine family" categories in some engine lines, particularly six-cylinder models. This can create potential confusion. E.g. 1MZ-FE – This is not a supercharged, narrow angle, fuel injected M-series engine, but a narrow angle, fuel injected MZ-series engine. Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance, 1MZ-FE rather than 1M-ZFE.
Starting in 2015, the designations after the dash have a maximum combination of three letters, even though there are more suffixes applicable, especially when newer engine technologies are introduced. For example, both the 2GR-FKS and 8AR-FTS engines have electronic multi-point fuel injection, but the "E" suffix is not included in the code.
The Dynamic Force engine series introduced in 2017 uses a naming scheme similar to that used by Honda and Suzuki. The two numbers between the first and second letters denote the displacement of the engine in liters. The suffix denoting the features of the engine is still used, as with prior engines.
Examples:
Some engines don’t share the same displacement as with the one found in the engine code. For example, the displacement of the V35A-FTS is closer to 3.4 L despite being marketed as a 3.5 L engine. Moreover, there are a few engines that use the naming scheme of the Dynamic Force family of engines but are not actually part of them, such as the diesel-powered F33A-FTV and the Gazoo Racing G16E-GTS.
Starting in 1957 until 1988, Toyota established a separate dealership in Japan dedicated to cars and trucks installed with diesel engines, called Toyota Diesel Store . When the dealership was disbanded, diesel products are now available at all locations, with commercial products exclusive to Toyota Store and Toyopet Store locations.

The Mazda B-series is a small-sized, iron-block, inline four-cylinder engine with belt-driven SOHC and DOHC valvetrain ranging in displacement from 1.1 to 1.8 litres. It was used in a wide variety of applications, from front-wheel drive economy vehicles to the turbocharged full-time 4WD 323 GTX and rear-wheel drive Miata.
The VG engine is a family of V6 engines designed and produced by Nissan between 1983 and 2004.
Toyota Motor Corporation's M family of engines were a longitudinally mounted straight-6 engine design. They were used from the 1960s through the 1990s. All M family engines were OHC designs. While the M family was born with a chain-driven single camshaft it evolved into a belt-driven DOHC system after 1980. All M family engines used a cast-iron block with an aluminum cylinder head, and were built at the Toyota Kamigo plant in Toyota City, Japan.
A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The CA engine is a series of 1.6 to 2.0 L Inline-4 piston engines from Nissan. It is designed for a wide variety of smaller Nissan vehicles to replace the Z engine and some smaller, four-cylinder L series engines. The "CA" stands for Clean Air, due to the installation of Nissan emission reducing technology, called NAPS-X.
The Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn.
The Toyota RZ engine family is a straight-four piston engine series built in Japan. The RZ series uses a cast-iron engine block and aluminum SOHC or DOHC cylinder heads. It has electronic fuel injection (EFI), 2 or 4 valves per cylinder and features forged steel connecting rods.
The Toyota VZ engine family is a series of V6 gasoline piston engines ranging from 2.0 to 3.4 L in displacement and both SOHC and DOHC configurations. It was Toyota's first V6 engine, being made as a response to Nissan’s VG engine, one of Japan's first mass-produced V6 engines.
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall. The engine first appeared in the Opel Kadett D in 1979, and shortly afterwards in its Vauxhall badged sister – the Vauxhall Astra Mk.1 in 1980. Despite this, the previous Opel OHV engine continued to be sold in entry level versions of the Opel Kadett/Astra and Corsa throughout the 1980s.
The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s.
The Daihatsu E-series engine is a range of compact three-cylinder, internal combustion piston engines, designed by Daihatsu, which is a subsidiary of Toyota. The petrol-driven series has cast iron engine blocks and aluminum cylinder heads, and are of either SOHC or DOHC design, with belt driven heads.
Designed by Aurelio Lampredi, the Fiat 124 engine first appeared in the all-new Fiat 124 in April 1966. The in-line four-cylinder engine comprised an iron block with an aluminium cylinder-head with pushrod actuated valves. The belt-driven design was ahead of its time when introduced. European production of the petrol versions ended with the Fiat 131 in 1984, but later diesel derivatives continued to be built until 1999. It did have a longer life in its twin-cam iteration, which continued in production until 2000. While originally of an overhead valve design, an overhead cam version was added to the facelifted 131 in 1981. The capacity was initially 1.2 L (1,197 cc), but eventually ranged between 1.2 and 1.9 L. There were also three SOHC diesel iterations of 1.4, 1.7, and 1.9 litres. The last versions of this engine to be built were the diesels. The 1.9 L (1,929 cc) direct-injected diesel version was the first direct-injection diesel to appear in a production passenger car, the Fiat Croma Turbo D i.d.
The Suzuki F engine is a series of inline three- and four-cylinder internal combustion petrol engines manufactured by Suzuki Motor Corporation and also licensed by many manufacturers for their automobiles. This engine was Suzuki's first four-stroke car engine when it first appeared in 1977.
Toyota has not published an explanation of the codes used for engine features. Matti Kalalahti derived a list of engine feature codes and published them on his "Engine codes explained" web page in Oct 1999.
