What does the i mean in car models?

The "i" in car models usually stands for "injection". This refers to the fuel injection system, which is a system that delivers fuel to the engine. Fuel injection systems are more efficient than carburetors, which were used in older cars. Fuel injection systems can also provide more power and better fuel economy.

Some car manufacturers also use the "i" in their model names to denote a specific trim level. For example, the Toyota Corolla i is a higher trim level than the Corolla L. The "i" trim level may include additional features, such as alloy wheels, a sunroof, and a higher-quality sound system.

The "i" in car models can also stand for "intelligent". This refers to the car's advanced technology features, such as self-driving capabilities, collision avoidance systems, and infotainment systems.
