Discovering the Lexus GX 550

The 2024 Lexus GX 550 ushered in a new chapter for the brand. This redesigned SUV offers an improved platform and powertrain, making minor improvements for 2025, such as adding driver memory settings and making the power-adjustable steering column standard. With the latest round of enhancements now in dealerships, there's no better time to discover the Lexus GX 550.

Upgrades and Innovations

The GX 550 represents a huge step forward for the GX Series. We take a closer look at how Lexus has elevated this luxury SUV.

Design and Styling Changes

Lexus has taken a more modern, minimalist approach to styling with the release of the GX 550. Lexus has pared back the enormous front grille seen on the GX 460 and subtly sculpted the classic boxy exterior, so it appears more refined.

A similar less-is-more strategy informs the interior styling. The dash isn't as cluttered as the GX 460’s, creating an open feel that reduces overwhelm when you're behind the wheel. Although you control the infotainment and climate settings using the touch screen instead of buttons, the setup is so intuitive that the transition is easy.

Enhanced Performance and Efficiency

Lexus has swapped out the second generation's outdated naturally aspirated engine with a smaller turbocharged powertrain. The new GX 550 engine improves performance and pulling power. It's also slightly more fuel efficient on the highway, although you probably won't notice a significant difference at the pump. That's impressive when you consider the substantial power increase.

New Technological Advancements

The turbocharged engine isn't the only new technology Lexus has introduced. Apple CarPlay and Android Auto connect wirelessly now to reduce cord clutter in the cabin. There's also an array of USB-C ports to ensure all devices stay powered up. A digital instrument gauge is another new addition for the third generation.

Performance Specifications

Assessing the GX 550’s performance specifications helps you understand how Lexus has improved its GX Series.

Engine and Transmission Details

A twin-turbocharged 3.4-liter V-6 engine powers all GX 550 trims. It generates 349 hp and 479 lb-ft of torque, all the better for traction when you're towing or hitting the trails. All trim levels also have four-wheel drive and a 10-speed automatic transmission system.

Acceleration

During independent testing, the entry-level GX 550 accelerated from 0 to 60 mph in 6.2 seconds. That's a full second faster than the GX 460 and current class competitors.

Towing and Payload Capabilities

The GX 550 can tow up to 9096 pounds, which is a massive 2,596-pound improvement on the previous generation. It's also more capable than other luxury SUVs.

Fuel Economy and Real-World Efficiency

The EPA estimates that the GX 550 will get 15 mpg in the city and 21 mpg on the highway. Real-world highway testing matched this estimate.

Interior Experience and Comfort

The 2025 Lexus GX 550 offers a sophisticated interior. The spacious standard cabin configuration features three rows of seating for up to seven people. If you want to sacrifice comfort for passenger room, you can replace the second-row bench with a couple of captain's chairs. Since the 2025 Luxury GX 550 third row offers limited space, it's best saved for small children who require less legroom. The Overtrail models are five-seaters with only two rows.

Chic faux leather upholstery makes even the entry-level and Overtrail trims feel luxurious. Lexus upgrades to real leather in the 2025 Lexus GX 550 Luxury interior.

Cargo Space

The standard GX 550 offers 10.3 cubic feet of cargo space behind the third row. That's a little smaller than other vehicles in this class, but with the rear seat folded down, this space expands to 40.2 cubic feet, which is similar to other luxury SUVs. If you're carrying bulky items, fold down both rows for 76.9 cubic feet of cargo space.

Infotainment and Connectivity Features

A glare-resistant high-definition 14-inch infotainment screen is the centerpiece of the GX 550’s cabin. The Lexus Interface lets you customize your driving experience with Profiles. Cloud Navigation helps you get where you need to go with real-time updates on traffic and roadworks. Wireless connection to Apple CarPlay and Android Auto allows easy access to your favorite mobile apps on the move. A 10-speaker audio system comes standard, with the option to upgrade to a premium 21-speaker Mark Levinson surround sound unit.

Safety and Assurance Features

The GX 550 prioritizes safety with the Lexus Safety System+ 3.0, which comes standard at all trim levels. This driver-assistance suite offers several standard safety features, including the following:

• Pre-collision system with pedestrian detection: Alerts you to hazards and automatically activates the brakes to avoid a collision if you're unresponsive
• Dynamic radar cruise control: Helps you maintain a consistent distance from traffic in front at high and low speeds
• Lane departure alert with steering assist: Alerts you to lane drifting and can adjust your steering to help you stay in your lane
• Lane tracing assist: Works with dynamic radar cruise control to keep your vehicle centered in its lane
• Road sign assist: Recognizes road signs and displays them inside the vehicle for easy reference
• Automatic high beams: Automatically toggles between low and high beams to suit conditions
• Proactive driving assist: Gently brakes and steers to help you maintain a safe distance from other vehicles, pedestrians, and cyclists
