2028 Lexus RX Morizo RR: Ready to Challenge German SUVs

High-performance RX emerges from test mule disguise

Spotted testing on European roads, the 2028 Lexus RX Morizo RR appears to be a dramatic departure from the RXs known for hushed luxury and hybrid efficiency. This prototype projects a track-focused personality: wider track, giant tires, massive brakes and aerodynamic tweaks that scream performance rather than comfort.

What the visuals reveal

The most telling clues come from the wheel-and-tire package. This mule rolls on Michelin Pilot Sport 4 SUV rubber, sized 265/40 R21 at the front and 295/35 R21 at the rear, a significant upgrade over the standard 235s seen on milder RX variants. The broader footprint gives the SUV a much more aggressive stance and suggests serious grip targets.

Behind multi-spoke wheels are ventilated, drilled rotors from Brembo clamped by red-painted calipers, a clear sign that stopping power is being prioritized. Up front, enlarged lateral openings flank the spindle grille, with lower intakes that look to house intercoolers. The hood wears a subtle power bulge under camouflage, while widened front and rear arches blend into pronounced side skirts.

At the rear, two large exhaust outlets dominate the bumper area. Observers should keep in mind test cars sometimes use provisional exhausts, but the aggressive layout points toward louder, more performance-oriented tuning than the current hybrid lineup.

Likely powertrain and performance targets

Under the skin, the RX Morizo RR is expected to move away from the 2.4L turbo-hybrid recipe of the lesser models. Rumors point to Toyota's new 2.0L turbo inline-four feeding a high-output system, possibly paired with electric motors on both axles to create an AWD performance setup. Talk in enthusiast circles estimates a combined output in the neighborhood of 600 horsepower, which would position the car directly against high-performance rivals.

Key suspected specs and features:

• Powertrain: new 2.0L turbo inline-four plus electric motors
• Drivetrain: AWD, likely a performance-tuned system
• Estimated output: around 600 hp (unconfirmed)
• Tires: Michelin Pilot Sport 4 SUV 265/40 R21 front, 295/35 R21 rear
• Brakes: Brembo ventilated and drilled rotors with red calipers

Morizo and RR: more than a badge

The Morizo name carries heritage. It traces back to Toyota chairman Akio Toyoda's racing alias and has been used on sportier Lexus models before. The RR label is less defined but has been paired with Morizo on smaller models like the LBX, which used a GR Corolla-derived powertrain and GR-Four AWD. Seeing both badges on a full-size RX signals Lexus wants to emphasize motorsport credibility for its most extreme offering.

How it stacks up against German rivals

If the power figures approach 600 hp, expect direct comparisons to the BMW X5 M Competition, Mercedes-AMG GLE 63 S and Audi RS Q8. Those SUVs typically feature V8 power, so a four-cylinder turbo plus electrification would continue the industry trend of extracting enormous output from smaller engines while relying on hybrid boost and electric torque fill.

Market timing and positioning

Lexus plans a mid-cycle refresh for the RX range in 2027, with less extreme variants debuting first. The Morizo RR performance model is anticipated to launch for the 2028 model year in markets like the US. If it delivers on promise, the RX Morizo RR could reshape expectations for what a luxury performance SUV can be from Lexus.

Highlights:

• Track-inspired chassis details and braking hardware
• Potential 600 hp hybridized powertrain
• Direct challenge to V8-powered German performance SUVs

Lexus is clearly intent on broadening the RX halo, and the Morizo RR prototype is the most visible sign yet that the brand wants to compete at the highest performance level without abandoning its engineering playbook on downsized, electrified powertrains.
