The Toyota NZ engine family is a straight-4piston engine series. The 1NZ series uses aluminum engine blocks and DOHC cylinder heads. It also uses sequential fuel injection, and has 4 valves per cylinder with VVT-i.
The engines are produced by Toyota's Kamigo Plant in Toyota, Aichi, Japan (1NZ for Prius, NZ for Vitz and ist, and R1NZ for Sienta);[2] by Siam Toyota Manufacturing in Chonburi, Thailand (NZ for NBC cars such as the 1NZ-FE for the Yaris and Vios);[5][6] and by Indus Motor Company in Karachi, Pakistan (2NZ for Corolla).[5]
1NZ-FXE[edit]
The 1NZ-FXE is a hybrid 1.5 L (1,497 cc) version. Bore and stroke is 75 mm × 84.7 mm (2.95 in × 3.33 in). It features forged steel connecting rods and an aluminum intake manifold. The engine has a high physical compression ratio of 13.0:1, but the closing of the inlet valve is delayed, for an effective compression ratio of 9.5:1[7]. The net result is that the engine has a greater effective expansion than compression—making it a simulated Atkinson cycle, rather than a conventional Otto cycle.
The reduction in cylinder charge means reduced torque and power output, but efficiency is increased. This combination makes the 1NZ-FXE suitable for use with the Hybrid Synergy Drive, where peak torque and power demands can be met by the electric motor and battery. Output is 76 hp (57 kW; 77 PS) at 5000 rpm with 115 N⋅m (85 lb⋅ft) of torque at 4000 rpm. Peak thermal efficiency is about 37%.[8] Production was discontinued in 2009, with the arrival of the 3rd generation Prius, which replaced the 1NZ-FXE with the 2ZR-FXE.
In 2012, upon the arrival of the Prius c (North America), the Aqua (Japan), and the Yaris Hybrid (Europe), an improved version was introduced. Without any belt-driven accessories, and a physical compression ratio of 13.4:1, the new version delivers an output of 74 hp (55 kW; 75 PS) at 4800 rpm with 111 N⋅m (82 lb⋅ft) of torque at 3600–4400 rpm.
The 1NZ-FXE Hybrid Synergy Drive in the Toyota Prius has won several International Engine of the Year awards:
- Best Eco-friendly 2000
- Best Eco-friendly 2001
- Best Fuel Economy 2005
- Best 1.4-litre to 1.8-litre 2005[9]
- Best Fuel Economy 2006
- Best 1.4-litre to 1.8-litre 2006[9]
Applications:
- Toyota Corolla (Axio/Fielder)
- Toyota Prius (XW10 & XW20)
- Toyota Probox[10]
1NZ-FXP[edit]
The 1NZ-FXP is a hybrid 1.5 L (1,497 cc) version. Bore and stroke is 75 mm × 84.7 mm (2.95 in × 3.33 in). It features forged steel connecting rods and an aluminum intake manifold. The engine has a high physical compression ratio of 13.0:1, but the closing of the inlet valve is delayed, for an effective compression ratio of 9.5:1[11]. The net result is that the engine has a greater effective expansion than compression—making it a simulated Atkinson cycle, rather than a conventional Otto cycle.
The reduction in cylinder charge means reduced torque and power output, but efficiency is increased. This combination makes the 1NZ-FXP suitable for use with the Hybrid Synergy Drive, where peak torque and power demands can be met by the electric motor, battery and LPG-hybrid system. Output is 76 hp (57 kW; 77 PS) at 5000 rpm with 115 N⋅m (85 lb⋅ft) of torque at 4000 rpm. Peak thermal efficiency is about 37%.[12].
Applications:
- Toyota JPN Taxi (NTP10)
1NZ-FE[edit]
The 1NZ-FE is a 1.5 L (1,497 cc) conventional Otto-cycle variant of the 1NZ-FXE with VVT-i. 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. Output is 109 hp (81 kW; 111 PS) at 6000 rpm with 141 N⋅m (104 lb⋅ft) of torque at 4200 rpm. The redline is 6400 rpm.
Applications:
- Toyota Vios/Belta
- Toyota Yaris/Echo
- Scion xA/Toyota ist
- Scion xB (1st generation)/Toyota bB (1st generation)
- Toyota Corolla (Axio/Fielder, RunX, Allex)
- Geely CK (Produced under license)
- Geely MK (Produced under license)
1NZ-FTE[edit]
The 1NZ-FTE is a 1.5 L (1,497 cc) with an air-to-air intercooler Turbocharged conventional Otto-cycle variant of the 1NZ-FXE with VVT-i. The engine block is found in many Toyota models assembled in Asian countries. It retains the same bore and stroke, but the compression ratio is lowered to 10.5:1. Output is 141–148 hp (105–110 kW; 143–150 PS) at 6000 rpm with 196–200 N⋅m (145–148 lb⋅ft) of torque at 4200-4800 rpm. The redline is 6400 rpm.
Applications:
- Toyota Vios Turbo (Thailand)
- Toyota Vitz RS Turbo/TRD Turbo M/GRMN Turbo (Japan)
- Toyota Yaris T Sport Turbo (Europe)
- Toyota Corolla Axio GT (Japan)
2NZ-FE[edit]
The 2NZ-FE is a 1.3 L (1,299 cc) version. Bore and stroke is 75 mm × 73.5 mm (2.95 in × 2.89 in), with a compression ratio of 10.5:1. Output is 63 kW (84 hp; 86 PS) at 6000 rpm with 121 N⋅m (89 lb⋅ft) of torque at 4400 rpm. In 2000, it won the International Engine of the Year award in the 1-litre to 1.4-litre category.[13]
Applications:
- Toyota Yaris/Echo/Vitz
- Toyota Vios/Belta
- Toyota Corolla (E140), Pakistan only
- Toyota Corolla (E170), Pakistan only
- Toyota Corolla (E120), Japan and Middle East only
- Nanjing Yuejin Soyat (based on the SEAT Ibiza Mark I)

The NZ Series
1nz Fxe
The NZ engine family is best known for its role in the Prius models from Toyota. The first-generation NZ utilizes aluminum engine blocks and aluminum dual overhead camshaft (DOHC) cylinder heads. It has four valves per cylinder and employs variable valve timing, intelligent (VVT-i). The 1NZ-FXE is a 1.5-liter engine built in Japan with forged steel connecting rods and an aluminum intake manifold. Its compression ratio is 13:1 with a delayed inlet valve closure, which simulates the Atkinson cycle, increasing efficiency and reducing torque output.
Unlike other high compression engines, the 1NZ-FXE is tuned specifically to improve fuel economy at the expense of power output, thus becoming a perfect candidate for the Hybrid Synergy Drive powertrain. This engine was introduced in 1999 and has won several awards since, including a series of International Engine of the Year awards from 2000 onwards. The 1NZ-FXE appears in the Prius and Prius c. The 1NZ-FE is the low-compression, 1.5-liter Otto cycle variant of the 1NZ-FXE with 107 horsepower and 103 lb-ft of torque. It appeared in the Yaris on which the Prius c was based. It has been replaced with the second-generation 2NZ-FE.

The NR Series
A compact straight-four engine series, the NR engines are 1.3-liter aluminum blocks with dual overhead cam (DOHC) cylinders and SFI fuel injection with four valves per cylinder utilizing variable valve timing (VVT-i) or dual VVT-i, depending on the application. Most NR engines are used in the European market, but some 1NR-FE engines appear in the Scion iQ in the U.S.
