Acura MDX vs. Lexus RX / TX & Genesis GV80: What You Need to Know Before You Decide

If you’re shopping for a three-row luxury SUV or a well-appointed midsize crossover, you’ve likely encountered three names near the top of your list: the Acura MDX, the Lexus RX and TX, and the Genesis GV80. Each of these vehicles represents a strong option in the premium segment, and each brings a distinct personality to the table. This guide is designed to help you cut through the noise and understand exactly how these vehicles compare — so you can make the most informed decision possible.

Powertrain & Performance

Each of these vehicles offers a distinct approach to power delivery.

Acura MDX is available with a 3.5-liter V6 producing approximately 290 horsepower, paired with a 10-speed automatic transmission. An MDX Type S trim is also available, powered by a turbocharged 3.0-liter V6 generating around 355 horsepower — giving the MDX one of the more performance-forward options in this group. All-wheel drive is available across the lineup, with Acura’s Super Handling All-Wheel Drive (SH-AWD) offered on select trims to enhance cornering dynamics.

Lexus RX offers a variety of powertrain choices depending on trim, including a 2.4-liter turbocharged four-cylinder, a 3.5-liter V6, and hybrid and plug-in hybrid options. The RX 350 generates approximately 275 horsepower, while the RX 500h F Sport Performance hybrid reaches around 367 horsepower. The Lexus TX similarly offers a 2.4-liter turbocharged engine producing approximately 275 horsepower, with hybrid options available as well.

Genesis GV80 comes standard with a 2.5-liter turbocharged four-cylinder producing approximately 300 horsepower, while a 3.5-liter twin-turbocharged V6 is also available, generating around 375 horsepower. All-wheel drive is standard across most trims.—

Interior, Technology & Features

Premium interiors are expected in this segment, and all three brands deliver — though with different priorities.

Acura MDX features a standard 12.3-inch dual-screen infotainment setup on most trims, with a True Touchpad Interface. Higher trims offer a 25-speaker ELS Studio 3D audio system, heated and ventilated front and second-row seats, and a panoramic sunroof. The MDX also includes Acura’s wireless Apple CarPlay and Android Auto on recent models, along with a head-up display on upper trims. The cabin uses premium materials, with open-pore wood and aluminum accents depending on trim.

Lexus RX and TX showcase some of the more dramatic interior changes in recent years, including an available 14-inch touchscreen infotainment system — a significant departure from Lexus’s older touchpad setup. Lexus is known for exceptional build quality and attention to detail, and the RX/TX continues that tradition. Available features include a Mark Levinson audio system, heated/ventilated front seats, a panoramic roof, and a 12.3-inch digital gauge cluster on higher trims. The TX adds third-row accommodations for families who need the additional space.

Genesis GV80 tends to offer generous standard feature content relative to its segment. Even on lower trims, the GV80 includes features that are often reserved for top-tier competitors. A standard 14.5-inch touchscreen, quilted Nappa leather, a Lexicon audio system (available), and a heads-up display are among the highlights. The GV80’s interior aesthetic leans into a design-forward, boutique sensibility.

Standard Safety & Driver Assistance Features

All three vehicles include a robust suite of standard driver assistance technologies. Here’s a comparative look:

• Acura MDX — Acura Safety Sense (AcuraWatch): forward collision warning, automatic emergency braking, lane departure warning, lane keeping assist, adaptive cruise control, blind-spot monitoring (available), and rear cross-traffic alert.
• Lexus RX / TX — Lexus Safety System+ 3.0 (standard): pre-collision system with pedestrian detection, radar cruise control, lane departure alert with steering assist, automatic high beams, and emergency steering assist.
• Genesis GV80 — Genesis Smart Sense (standard): forward collision avoidance, lane keeping assist, driver attention warning, blind-spot collision avoidance, and rear cross-traffic collision avoidance — with a surround-view monitor standard on most trims.

All three brands include multiple airbags, rear backup cameras (required by law), and access to additional safety packages on upper trims.

Frequently Asked Questions

Is the Acura MDX bigger than the Lexus RX? 

Yes, generally speaking. The Acura MDX is a three-row SUV and is longer overall than the two-row Lexus RX. For a closer size comparison, the Lexus TX — Lexus’s three-row model — is a more direct match in terms of footprint and intended use.

Does the Genesis GV80 come in a three-row configuration? 

Yes. The GV80 is available in both two-row (five-passenger) and three-row (six- or seven-passenger) configurations, though availability varies by trim and market. Always confirm current configuration options with your local Genesis dealer.

Which of these vehicles has a hybrid option? 

The Lexus RX and TX both offer hybrid and, in some cases, plug-in hybrid powertrains. As of the current model year, the Acura MDX and Genesis GV80 do not offer hybrid configurations, though both offer strong turbocharged or naturally aspirated engine options.

The Acura MDX is rated for up to approximately 5,000 lbs., while the Lexus RX and TX are rated for up to approximately 3,500 lbs.

Which vehicle has the best warranty? 

Warranty coverage varies by brand. Genesis is known for offering an industry-notable 10-year/100,000-mile powertrain warranty on its vehicles. Acura and Lexus both offer competitive limited warranties as well. Buyers should review current warranty terms directly with each brand, as coverage details can change.

Is the Lexus brand more reliable than Acura or Genesis? 

Reliability rankings from organizations like J.D. Power and Consumer Reports can vary year over year and by specific model. Lexus has historically ranked highly in long-term reliability studies. Both Acura and Genesis have also received strong marks in recent years. We encourage shoppers to review the most current third-party reliability data when making their decisions.

Do all three vehicles offer all-wheel drive? 

All-wheel drive is available on the Acura MDX and Lexus RX/TX, and is standard on most Genesis GV80 configurations. Buyers should confirm AWD availability for their preferred trim level with the relevant dealer.

Can I fit three car seats across the second row in any of these vehicles? 

Second-row width and LATCH anchor placement varies by vehicle. We recommend visiting a dealer with your car seats in hand to test fitment, as this is highly specific to each family’s situation and equipment.
