From 2012 to 2020, the 1.0-liter 3-cylinder Hyundai G3LB or 1.0 TCI engine was manufactured and used in small cars like the Ray or the Morning, which is the Korean equivalent of the Picanto. Distributed injection and turbocharging, which are uncommon for this series, set the unit apart.

G3LA, G3LB, G3LC, G3LD, G3LE, and G3LF make up the Kappa R3 family.
The engine was mounted on:
- Kia Picanto 2 (TA) in 2015 – 2017; Picanto 3 (JA) in 2017 – 2020;
- Kia Ray 1 (TAM) in 2012 – 2017.
