The Toyota 1ZR-FE and 2ZR-FE are modern gasoline engines from Toyota's ZR engine family, designed for compact cars and entry-level sedans. These inline-four cylinder engines feature Dual VVT-i (Variable Valve Timing-intelligent) on both intake and exhaust camshafts, delivering excellent fuel efficiency, smooth power delivery, and reliable performance for urban commuting and daily driving. The 2ZR-FE 1.8L variant is widely used in Toyota Corolla, Allion, Auris, and related platforms globally.
