The 2AR-FXE is an Atkinson cycle variant of the 2AR-FE. It has the same bore and stroke, but the cams and pistons are unique.
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 2AR-FXE suitable for use 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 154 hp with 153 lb·ft of torque which doesn't include the additional power of the electric motor that is used in the Camry Hybrid.
Applications:
- Toyota Camry Hybrid (AVV50)
