The 2AZ-FXE is an Atkinson cycle variant of the 2AZ-FE. It has the same bore and stroke, but the cams and pistons are unique. It has a physical compression ratio of 12.5:1.
The large valve overlap leads to a reduction in cylinder charge and reduced torque and power output, but efficiency is increased. This combination makes the 2AZ-FXE suitable for use only in hybrid vehicles, where peak torque and power demands can be met by the electric motor and battery.
Maximum output when used in the Camry hybrid is 147 hp (108 kW) at 6000 rpm with 138 lb·ft (187 N·m) of torque at 4400 rpm.
