What is the approach angle of the Lexus GX 470?
The approach angle of the Lexus GX 470 is roughly 27 degrees, though exact figures vary by year, trim, tire size and any aftermarket modifications. This article explains what that angle means for off-road capability and how it is measured.
Understanding the figure and its practical meaning
The approach angle describes the steepness of an obstacle a vehicle can encounter with its front bumper before it starts to scrape. For the GX 470, a figure around 27 degrees suggests respectable capability for mixed-terrain driving, particularly for a luxury SUV that emphasizes on-road comfort as well as off-road ability.
Alongside the approach angle, two related measurements—departure angle and breakover angle—provide a fuller picture of a vehicle’s obstacle-clearing profile on trails.
The figures commonly cited for the GX 470 (subject to variation by year, tire size, and equipment) are listed below.
- Approach angle: approximately 27 degrees
- Departure angle: approximately 23 degrees
- Breakover angle: approximately 19–21 degrees
These numbers should be treated as general guidance. Real-world performance depends on several variables, including tire diameter, suspension setup, bumper design, and any lift or aftermarket components.
Measurement factors and how they can shift the numbers
The GX 470’s angles are not fixed across all models. Differences in model year, factory wheels, tire sizes, and optional equipment can shift the readings by a few degrees. Always verify with your specific vehicle configuration when planning off-road routes.
Why the GX 470’s approach angle matters for owners and buyers
A higher approach angle generally means better ability to tackle steep, sharp-edged obstacles without front-end contact. For a luxury SUV like the GX 470, the angle represents a balance between on-road refinement and off-road capability, rather than a rugged rock-crawler profile.
Summary
The Lexus GX 470 typically reports an approach angle around 27 degrees, with a departure angle near 23 degrees and a breakover angle around 19–21 degrees in stock form. These values vary by year and equipment, and can change with tires, suspension, or aftermarket components. Used in context, they offer a practical gauge of the SUV’s obstacle-clearing capabilities on mixed-terrain adventures.
Which is bigger, the Toyota Sequoia or the Lexus GX 460?
Lexus GX 460 Exterior. The 2022 Toyota Sequoia measures 205″ L x 80″ W x 77″ H and includes 18- or 20-inch wheels. The 2022 Lexus GX 460 is a smaller model, measuring 192″ L x 74″ W x 74″ H, but also includes 18- or 20-inch wheels.
What is the approach angle of the GX470?
Ground clearance measured 211 mm (8.3 in), with an approach angle of 30° and a departure angle of 29° raised (25° normal). The GX 470 carried a drag coefficient of Cd=0.38.
What year to avoid Lexus GX 470?
The 2003 Lexus GX470 is often cited as the worst model year due to drivetrain issues like clunking noises, and the 2006 model also received a high number of complaints, particularly for drivetrain problems. Other years to be cautious about include models with the optional KDSS system for off-road enthusiasts due to potential costs, and early models (2004 and 2005) for dashboard cracks, dry-rotted wheels, and less engine power compared to later models.

Specific model years to be cautious about
- 2003 Lexus GX470: Considered the worst model year by some sources due to specific drivetrain issues, such as clunking and squealing noises, and higher repair costs.
- 2006 Lexus GX470: Received a high number of owner complaints, particularly regarding drivetrain problems.
- Models with KDSS: If you plan to heavily modify the vehicle for off-roading, models with the Kinetic Dynamic Suspension System (KDSS) may be best to avoid due to potential complexity and cost of repairs or modifications.
Common issues across the GX470 lifespan
- Drivetrain issues: Reports of clunking and squealing noises have been associated with certain model years.
- Dashboard cracks: A common and potentially expensive issue across many model years, especially in warmer climates.
- Timing belt and water pump: A crucial maintenance item. The timing belt should be replaced around every 90,000 miles, or the vehicle should have a documented history of this replacement.
- Navigation system: The built-in navigation system is outdated and can be difficult to upgrade or repair. Many owners recommend using a smartphone for navigation instead.
- Suspension and transmission: During a test drive, listen for unusual noises from the suspension and check for smooth transmission shifts, as these can indicate wear.
