What year Corolla is the most reliable?
2011-2013. These three years of the 10th-gen Toyota Corolla go for relatively cheap, usually between $10,000-$12,000. They have high reliability ratings and good gas mileage (27-city/34-highway mpg).
What kind of engine does a Toyota Corolla have?
Toyota designed this engine with fuel economy in mind. The 4A-FE is basically the same as the 4A-F (introduced in the previous generation of Corollas), the most apparent difference being the electronic fuel injection system as noted by the E. The engine was succeeded by the 3ZZ-FE, a 1.6-liter engine with VVT-i technology.

What’s the peak torque of a Toyota Corolla?

Fuel economy and exact engine sizes: The 2009 Corolla XRS switched from the Celica engine to the Camry’s four-cylinder; horsepower went from 180 to 158, but there was better midrange power. Torque was rated at 162 pound-feet.
How are fuel injectors fired on a Toyota Corolla?
While every fuel injector had fired at once on the 4A-F, with two at a time on the 4A-FE (so one was firing against a closed valve), the 1ZZ-FE and newer engines fired each injector, only when the intake valve for that cylinder was open. Likewise, the electronic ignition of the 4A gave way to direct ignition on the ZZ and later engines.
