What does the iM stand for in Corolla iM?


Corolla iM
The “i” stands for individual. Intriguing. Easy on the customer's income. For the M, think modern, multi-faceted and magnetic.



What is the difference between 1.8 and 2.0 Corolla engine?


The base 1.8-liter four-cylinder struggles to haul the Corolla around with urgency, and it sounds coarse when accelerating hard. The available 2.0-liter engine provides sprightlier acceleration, but it's still rather buzzy at higher rpm.



Which car has a 1ZZ engine?


The 1ZZ engine has powered many of Toyota's most famous models, such as the Corolla and Celica.



Is the 2018 Toyota Corolla iM a good car?


More fun to drive than the Corolla sedan, standard manual transmission, desirable standard features. Impractically small back seat, woefully underpowered engine, disappointing infotainment system. The Toyota Corolla iM looks slick and drives well, but its weak engine and tiny back seat hurt its desirability.
