There are two confirmed engine variants available on debut.
1. 1.5-liter naturally-aspirated SkyActiv-G generating only 99 firepowers! so seriously underpowered. This would not be sold in the states. However, this utmost "econo" engine would be surely Thais' favorite
2. 2.0-liter SkyActiv-G engine. The firepower is yet to be announced, however, one could expect between 165 to 200.
