Most engines in this family are equipped with Toyota's dual VVT-i technology that optimizes both intake and exhaust valve timing.

This engine family is also the first to use Toyota's Valvematic system, first appearing on the Noah and Voxy in 2007 and then the European Avensis in 2009.

[1] [2] The Toyota 1ZR-FBE is a flex fuel version of the 1ZR-FE the DOHC, 16-valve, 1.6 L (1,598 cc) engine also equipped with Dual VVT-i and Valvematic.

Unlike the original 2ZR-FAE, this version was created by simply adding the Valvematic system to the standard 2ZR-FE engine used in the Toyota Corolla Altis sold there, resulting in total power of 140 PS (103 kW; 138 hp) at 6200 rpm and a peak torque of 172 N⋅m; 127 lbf⋅ft (17.5 kg⋅m) at 4000 rpm.

[6] The Toyota 2ZR-FBE is a flex fuel version of the 2ZR-FE the DOHC, 16-valve, 1.8 L (1,798 cc) engine also equipped with Dual VVT-i and Valvematic.

[9] It has the same bore and stroke, but the compression ratio is increased to 13.0:1, and the inlet valve closing is late-staged.

Output is 73 kW (98 hp; 99 PS) at 5200 rpm and 142 N⋅m (105 lb⋅ft) of torque at 4000 rpm, paired with electric motor/generators in the hybrid drive system; together the engine and electric motors produce up to 103 kW (138 hp; 140 PS) and 207 N⋅m (153 lb⋅ft).

The Toyota 8ZR-FXE is a 1.8 L (1,797 cc) Atkinson cycle engine paired with electric motor/generators in a hybrid drive system.

[14] Specifications Applications The Toyota 8ZR-FXE is a 1.8 L (1,797 cc) Atkinson cycle engine paired with electric motor/generators in a hybrid drive system.

[17] The plant also supplies these engine parts to Toyota's assembly lines in France, Turkey, South Africa and Japan.
