It has a 3VZ-FE
The
1NZ-FXE is the earliest 1.5 L (1496 cm³) version built in Japan. Bore is 75 mm and stroke is 84.7 mm. It features forged steel connecting rods and a plastic composite intake manifold. The engine has a high physical compression ratio of 13.0:1, but the inlet valve closing is retarded. The net result is that the engine has a greater effective expansion than compression – making it Atkinson cycle, rather than the 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 57 kW (76 hp) at 5000 rpm with 115 Nm (85 ft·lbf) of torque at 4000 rpm.
