From 1999 to 2005, a Korean factory produced the 1.3-liter 8-valve Kia A3E engine, which was only fitted to the most basic versions of the first generation of the well-liked Rio model. The popular Japanese Mazda B3 engine serves as the foundation for this power unit.

A3E, A5D, BFD, S5D, A6D, S6D, T8D, FED, and FEE are engines made by Kia.

Disadvantages of the Kia A3E engine
This unit is straightforward but uninspired, and all issues stem from normal wear and tear;
The valve bends when the timing belt breaks, which can happen even after 50,000 kilometers;
from inexpensive grease, the hydraulic lifter wedge, and the oil pump pressure-reducing valve;
Oil scraper rings frequently lie down and an oil burn starts closer to 200,000 km;
frequently damages the gasket, ignition system parts, and the fuel pump.
