The Hyundai / Kia 3.8L G6DN Lambda II GDI V6 engine is a refined member of Hyundai’s Lambda engine family, designed to deliver strong performance, improved fuel efficiency, and long-term reliability. Introduced around 2018, the G6DN represents the latest evolution of the Lambda II series, incorporating modern combustion technology and advanced efficiency improvements.
With a displacement of 3.8 liters (3778 cc), this naturally aspirated V6 engine uses gasoline direct injection (GDI) and operates on an Atkinson cycle, helping to optimize fuel efficiency while maintaining solid power output. It typically produces around 290–295 horsepower and 355 Nm of torque, making it well-suited for large SUVs and premium vehicles that require both power and smooth operation.
Constructed with a lightweight aluminum block and cylinder heads, the G6DN features a DOHC 24-valve configuration with Dual CVVT (Continuously Variable Valve Timing). These technologies enhance airflow, improve combustion efficiency, and ensure responsive acceleration across a wide RPM range.
As part of the broader Lambda II engine family, the G6DN benefits from years of engineering development, including improved durability, refined engine balance, and reduced emissions. It is commonly found in vehicles such as the Hyundai Palisade and Kia Telluride, where reliability and consistent performance are essential.
This engine is particularly valued for its smooth power delivery, low vibration levels, and dependable long-term performance, making it a strong choice for replacements, rebuilds, or upgrades in compatible Hyundai and Kia vehicles.
