The 1ZZ-FE engine is a newly developed in-line 4-cylinder, 1.8-liter, DOHC 4-valve engine mounted in the new Corolla. Abounding in new technologies including the laser-clad valve seat, high-pressure die-cast aluminum cylinder block, and the small-pitch chain drive DOHC, coupled with the fundamentally reviewed basic specifications, the new engine is compact and lightweight, offering high performance and good fuel economy. Anticipating even more stringent emission regulations in the future, in addition to the revision of the engine body, the layout of the exhaust system has been improved to enhance warm-up performance of the converter.

Newly developed 2VZ-FE engine for CAMRY is a 2.5-liter water cooled and V-type 6-cylinder engine exported from TOYOTA for the first time. This engine has the TOYOTA original 4-valve DOHC system. That is, exhaust camshafts driven by intake camshafts using scissors gears. By its compact configuration with the gear driven camshafts, this V-type 6-cylinder engine is mounted on a front-wheel-drive vehicle which originally had an in-line 4-cylinder engine. By increasing IVZ-FE engine displacement (for domestic), compact pentroof-type combustion chambers, optimum air-fuel ratio and ignition timing by TCCS (TOYOTA Computer Controlled System) and other technologies, a high performance 153HP/5600rpm and a large torque 155ft·lbs/4400rpm have been achieved with a low fuel consumption.
