What car is the Lexus GX based on?

The Lexus GX is a mid-size luxury SUV that has been a part of the Lexus lineup since 2002. While it may seem like a unique Lexus model, the GX is actually based on a Toyota platform, sharing its underpinnings with the Toyota 4Runner.


Toyota 4Runner Roots


The Lexus GX is closely related to the Toyota 4Runner, a popular mid-size SUV known for its off-road capabilities. The GX is essentially a more luxurious and refined version of the 4Runner, sharing the same body-on-frame construction and many of the same mechanical components. This shared platform allows the GX to offer similar off-road performance and durability as the 4Runner, but with a more premium interior and additional luxury features.


Shared Underpinnings


The Lexus GX and Toyota 4Runner are built on the same truck-based platform, which provides a robust and capable foundation for both SUVs. This platform, known as the Toyota Tacoma platform, has been used for various Toyota and Lexus models over the years, including the Sequoia and Land Cruiser. The shared underpinnings allow the GX to benefit from the 4Runner's proven off-road capabilities, while Lexus can add its own unique styling, features, and luxury touches to create a more premium offering.


Differences Between the GX and 4Runner


While the Lexus GX and Toyota 4Runner share a common platform, there are several key differences between the two SUVs:



  • Exterior and Interior Design: The GX features a more upscale and refined exterior design, as well as a more luxurious and well-appointed interior compared to the 4Runner.

  • Engine and Powertrain: The GX is powered by a 4.6-liter V8 engine, while the 4Runner offers a range of engine options, including a V6 and a turbocharged four-cylinder.

  • Technology and Features: The GX comes standard with a host of premium features and advanced technologies, such as a premium audio system, a larger infotainment display, and more advanced safety systems.

  • Pricing: As a Lexus model, the GX is priced significantly higher than the 4Runner, reflecting its more luxurious positioning in the market.


Despite these differences, the Lexus GX and Toyota 4Runner share a common DNA, with the GX offering a more premium and refined take on the 4Runner's proven off-road capabilities and durability.
