Does the Lexus GX come in V6?
Yes—the current-generation Lexus GX uses a 3.4-liter twin-turbo V6, signaling a shift from the older GX 460’s 4.6-liter V8. This article explains the engine evolution, what it means for performance, and how buyers should think about the V6 option.
Engine history and current configuration
Overview of how the GX’s powertrain has evolved and what drives the latest generation.
- GX 460 (model years 2009–2023): powered by a 4.6-liter V8 with roughly 301 horsepower and 329 lb-ft of torque.
- Current-generation GX (introduced for the 2024 model year): uses a 3.4-liter twin-turbo V6; paired with an eight-speed automatic and typically equipped with all-wheel drive on most trims.
The shift from a naturally aspirated V8 to a turbocharged V6 aligns with Lexus/Toyota’s broader industry move toward downsized, efficient powertrains while preserving off-road capability and luxury features. Availability can vary by market and trim; local dealer specifications should be confirmed.
Performance and efficiency implications
The V8 delivered a familiar, linear torque feel and a traditional engine soundtrack, while the V6 turbo aims to deliver strong low-end torque with improved efficiency. Exact output can vary by market and model, but the engine is designed to deliver robust acceleration for a mid-size SUV while maintaining Lexus reliability.
What this means for buyers
Pros and considerations when choosing a GX with a V6 engine.
- Pros: improved fuel economy versus the older V8, strong low-end torque from turbo charging, compatibility with Lexus’ latest technology and safety features, and retained off-road capability.
- Considerations: turbocharged characteristics differ from a naturally aspirated V8 (potential turbo lag in some conditions), and maintenance costs are comparable to other modern turbo engines; availability may vary by trim and region.
For buyers who want a modern, luxuriously appointed SUV with capable off-road performance and better efficiency, the V6-powered GX offers a compelling package compared with the earlier V8-era models.
Model-year and market notes
The GX line has evolved in recent years, with the U.S. market adopting the V6-turbo configuration in the latest generation. Some overseas markets may feature variations in powertrains, so it’s wise to check local specs with a dealer before purchase.
Summary: The Lexus GX now comes with a V6 engine in its latest generation, replacing the older V8-powered setup found in earlier GX 460 models. This change reflects a broader industry trend toward downsized, turbocharged powertrains while preserving the GX’s luxury and off-road capability.
Summary: For buyers seeking a modern Lexus SUV that combines upscale comfort, technical sophistication, and capable off-road performance, the current GX’s V6 engine meets those needs without sacrificing the brand’s renowned reliability.
