Lexus TZ9 EV Spotted: Toyota Highlander-Based Electric Flagship Emerges with Premium Upgrades

Lexus has officially confirmed the existence of its long-rumored three-row electric SUV, the TZ9, following the first sighting of a camouflaged prototype in active testing. The model shares its fundamental architecture with the newly introduced Toyota Highlander EV, but Lexus has applied its signature design refinements to create a distinct flagship offering.

The TZ9 is positioned to compete directly with premium three-row electric SUVs, including the Volvo EX90, Hyundai Ioniq 9, and Kia EV9, with a naming convention that aligns with Lexus’s ‘TZ’ series and a ‘9’ suffix to denote its segment-leading aspirations.

Design: A Polished Take on the Toyota Highlander EV

The camouflaged prototype reveals that the TZ9 retains the Highlander EV’s overall shape and proportions but introduces several Lexus-specific design elements. Up front, the SUV features split headlights and a cleaner, less cluttered front bumper, moving away from the Highlander’s more utilitarian styling. The wheel arches are slightly more squared off, and the prototype rides on bespoke wheels that differ from the Toyota’s offerings.

While the rear of the vehicle remains heavily camouflaged, early observations suggest the taillights may mirror the Highlander’s general shape but could extend further down the sides. Lexus has also subtly altered the door skins and side windows, though the core structure aligns closely with the Highlander EV.

Dimensions: Close to the Toyota Highlander EV

The TZ9 is expected to share nearly identical dimensions with the Toyota Highlander EV, with only minor adjustments for its unique body panels. Key measurements include:

• Overall length: 198.8 inches
• Overall width: 78.3 inches
• Overall height: 67.3 inches
• Wheelbase: 120.1 inches

These dimensions place the TZ9 in the same size class as its rivals, ensuring competitive interior space and cargo capacity.

Powertrain: Lexus Likely to Enhance Toyota’s Hardware

While Lexus has not yet confirmed the TZ9’s powertrain specifications, industry analysts expect the SUV to leverage Toyota’s existing electric vehicle architecture with potential upgrades to meet Lexus’s performance and refinement standards. The Toyota Highlander EV’s base configuration includes:

• A 77 kWh battery paired with a single motor producing 221 hp and 198 lb-ft (268 Nm) of torque.
• An all-wheel-drive (AWD) variant with a 95.8 kWh battery, 338 hp, 323 lb-ft (438 Nm) of torque, and a claimed range of up to 320 miles (515 km).

However, given the rapid advancements in battery technology among competitors, the TZ9 may adopt a larger battery pack to deliver superior range and performance. For context, the Volvo EX90 features a 111 kWh battery, while the Hyundai Ioniq 9 is equipped with a 110.3 kWh battery, both targeting longer real-world driving ranges.

Interior: Lexus’s Signature Premium Touch

While official interior images of the TZ9 have not yet been released, early glimpses of the door panels reveal Lexus’s commitment to its hallmark premium design language. The cabin is expected to feature high-quality materials, advanced infotainment systems, and Lexus’s latest driver-assistance technologies, aligning with the brand’s reputation for luxury and refinement.

As the automotive industry accelerates toward electrification, the Lexus TZ9 represents the brand’s strategic move to capture a share of the growing three-row electric SUV market, offering a blend of Toyota’s engineering prowess and Lexus’s luxury pedigree.
