For years, luxury SUV buyers seeking three-row spaciousness often had to compromise on fuel economy. However, the all-new Lexus TX has arrived to change the game, establishing itself as a frontrunner in the Highest Mpg Luxury Suv category. While Lexus may have been a bit late to the three-row SUV party, the 2025 TX, now in its second model year, compensates handsomely with a roomy interior, cutting-edge technology, comprehensive safety features, and most importantly, a range of powertrains designed for efficiency, including hybrid and plug-in hybrid options. This blend of attributes positions the TX as a unique offering, especially for those prioritizing fuel savings without sacrificing luxury and space.
Positioned strategically above the popular Lexus RX, the TX effectively bridges the gap to the larger, truck-based LX, which itself is a more opulent, three-row iteration of the Toyota Land Cruiser. Lexus previously attempted to address the three-row need with the RX-L, an extended version built on the standard RX wheelbase. However, the mere six-inch increase in overall length resulted in a cramped third row and limited cargo capacity. The TX decisively overcomes these shortcomings.
The Lexus TX distinguishes itself with a longer wheelbase, ensuring generous legroom in both the second and third rows, coupled with superior cargo space compared to competitors, regardless of seating configuration. The standard TX configuration comfortably accommodates seven passengers. For those preferring a more premium second-row experience, optional captain’s chairs and a rear center console are available, reducing capacity to six. Crucially, the third row in the TX is genuinely usable; it’s not a penalty box but a relatively spacious area where two adults can comfortably settle in for longer journeys.
Inside, the TX is packed with modern technology, headlined by a prominent 14-inch touchscreen interface. Wireless Apple CarPlay and Android Auto are standard, along with a suite of over a dozen advanced driver-assistance features, enhancing both convenience and safety. Under the hood, the standard four-cylinder engine is adequate for everyday driving, but for a vehicle of this size, it can feel somewhat strained when pushed. For a more refined and efficient driving experience, the 366-horsepower hybrid powertrain is significantly better suited. For those seeking the highest mpg luxury SUV capabilities within the TX lineup, the 404-horsepower, V6-based plug-in hybrid emerges as the star. This model not only delivers robust performance but also achieves up to 29 mpg combined and offers a commendable all-electric range of up to 33 miles, further solidifying its place as a leader in fuel-efficient luxury SUVs.
This powertrain versatility places the Lexus TX in competition with a diverse set of rivals. Traditional gasoline-powered competitors include the Acura MDX, Lincoln Aviator, and Volvo XC90. However, the TX truly shines when compared to hybrid and plug-in hybrid competitors like the Volvo XC90 Recharge, BMW X5, and Mercedes-Benz GLE, particularly when focusing on achieving the highest mpg luxury SUV in real-world driving. With a starting price around $56,000, the Lexus TX is positioned to attract a broad spectrum of SUV buyers seeking a balance of luxury, space, technology, and exceptional fuel efficiency.
In conclusion, the Lexus TX is more than just a new entrant in the three-row luxury SUV segment; it’s a statement. It effectively combines spaciousness and luxury with impressive fuel economy, especially through its advanced hybrid and plug-in hybrid powertrains. For buyers prioritizing efficiency in a premium SUV without compromising on space or features, the Lexus TX stands out as a compelling option and a true contender for the highest mpg luxury SUV title in its class.
