Is Lexus GX V6 or V8?
The Lexus GX is powered by a V8, not a V6.
As of 2024–2025, the GX sold in most markets uses a 4.6-liter V8 engine (1UR-FE) paired with an eight-speed automatic. Lexus has not offered a V6 variant of the GX in its standard lineup. This setup has defined the model’s character, delivering solid low-end torque, towing capability, and off-road confidence. Here’s a closer look at how the GX engine lineup has evolved and what it means for buyers.
Engine history and current setup
Historically, the GX family has relied on V8 power, with each generation refining the displacement and tuning while keeping V8 fundamentals front and center.
- GX470 (2003–2009): 4.7-liter V8 (2UZ-FE)
- GX460 (2009–present): 4.6-liter V8 (1UR-FE)
In short, the GX lineage has stayed committed to V8 power through its current generation, and there is no V6 option in the standard GX lineup today.
Summary
For buyers, that means the GX continues to emphasize traditional V8 performance—strong pulling power and robust off-road capability—at the expense of fuel economy compared with smaller or turbocharged alternatives. If a V6 is a priority, other Lexus models (and the larger LX lineup, which offers a turbocharged V6 option) provide different powertrain choices. The GX remains a rugged, reliable choice for those who value engine character and enduring capability.
