The 4A-GE produced at 6,600 rpm and of torque at 4,800 rpm in the American market. The use of a vane-type air flow meter (AFM), which restricted air flow slightly but produced cleaner emissions that conformed to the U.S. regulations, limited the power considerably - the Japanese model, which uses a manifold absolute pressure (MAP) sensor, was originally rated at . However, this was a gross power rating and the engine was later re-rated at net. Nonetheless, Japanese cars tested no faster than their American counterparts despite their higher power rating and a lower curb weight.
