What is the name of the engine in the Toyota Corolla?
The Toyota Corolla, one of the world's best-selling and most popular compact cars, is powered by a range of efficient and reliable engines. The specific engine that powers the Toyota Corolla varies depending on the model year and market, but the most common engine found in the Corolla is the 1.8-liter inline four-cylinder engine.
The 1.8-Liter Inline Four-Cylinder Engine
The 1.8-liter inline four-cylinder engine is the primary powerplant for the Toyota Corolla in many markets around the world. This engine, also known as the 2ZR-FE, is a naturally aspirated, dual overhead cam (DOHC) design that produces between 132 to 139 horsepower, depending on the specific model and market.
The 1.8-liter engine in the Corolla is known for its excellent fuel efficiency, smooth operation, and reliability. It utilizes Toyota's advanced engine technologies, such as variable valve timing, to optimize performance and efficiency.
Other Engine Options
While the 1.8-liter inline four-cylinder is the most common engine found in the Toyota Corolla, some markets and model variants may offer alternative engine choices, including:
- 1.6-liter inline four-cylinder engine
- 2.0-liter inline four-cylinder engine
- Hybrid powertrain options, combining a gasoline engine with an electric motor
The availability of these alternative engines can vary depending on the specific Corolla model, market, and customer preferences.
In summary, the Toyota Corolla is primarily powered by a 1.8-liter inline four-cylinder engine, known for its efficiency, reliability, and smooth performance. This engine is a key component that has contributed to the Corolla's enduring popularity and success as one of the world's most widely recognized and best-selling compact cars.

What is a 2ZZ engine?
The 2ZZ-GE is a 1.8 L; 109.6 cu in (1,796 cc) version built in Japan, in collaboration with Yamaha Motor Corporation. Bore x stroke is 82 mm × 85 mm (3.23 in × 3.35 in). It uses Multi-point Fuel Injection, VVTL-i, and features forged steel connecting rods.
How are Toyota engines named?
Toyota engine nomenclature follows a pattern of engine family, displacement, and features. The first one or two letters identify the engine family (e.g., AZ, 1KD), the number(s) often indicate displacement (e.g., M20A for 2.0L), and subsequent letters describe key features like DOHC (G), turbocharging (T), or fuel injection systems. For newer engines like the Dynamic Force line, the displacement is incorporated directly into the code, such as M20A.
Decoding an engine code
- Engine Family: The first letters denote the engine family or series (e.g., S in 3S-GTE, KD in 1KD-FTV, UR in 1UR-FSE).
- Generation/Variant: The number(s) preceding the family letters often represent the engine generation or model, though this is not always the case.
- Displacement: In more modern engines (like the Dynamic Force line), the displacement is incorporated into the code. For example, the 20 in M20A signifies a 2.0L engine.
- Engine Features: Letters following a hyphen describe specific features:
- G: DOHC: (performance, wide-angle valve head) or F (economy, narrow-angle valve head, twin-cam)
- T: Turbocharged:
- Z: Supercharged:
- E: Fuel Injection: (multi-point fuel injection) or S (D-4S direct injection)
- X: Hybrid: (indicates hybrid engine, as seen in 1NZ-FXE)
- V: Variable Valve Timing: (in some cases, often combined with D-4D for diesel)
Examples
- 3S-GTE:
- 3S: Third model in the "S" engine family.
- G: DOHC performance cylinder head.
- T: Turbocharged.
- E: Multi-point fuel injection.
- 1UR-FSE:
- 1UR: First model in the "UR" engine family.
- F: Narrow angle DOHC.
- S: D-4S gasoline direct injection.
- E: Multi-point fuel injection.
- 1KD-FTV:
- 1KD: First model in the "KD" engine family.
- F: Narrow angle DOHC.
- T: Turbocharged.
- V: D-4D common rail direct injection (diesel).
What is a 1NZ engine?
The 1NZ-FE is a 1.5 L (1,497 cc) conventional Otto-cycle variant of the 1NZ-FXE with VVT-i on the intake camshaft. The engine block is found in many Toyota models assembled in Japan and Asian countries. It retains the same bore and stroke, but the compression ratio is lowered to 10.5:1.
