2025 Toyota Sienna vs 2025 INFINITI QX80

The 2025 INFINITI QX80 underwent its first redesign since 2017, growing slightly longer and wider while maintaining its height. It retained its body-on-frame architecture, but with a new frame that significantly improved torsional and lateral stiffness. The QX80's styling became more expressive, particularly at the front, with a larger grille and a distinctive stacked-headlight setup. The rear end retained its general shape but featured full-width taillights with over 300 LEDs. The QX80 was available in four trim levels, with the base Pure trim featuring 20-inch wheels and the others equipped with 22-inch wheels. The interior received a high-tech makeover, including a large horizontal display and 64-color ambient lighting. Upholstery options ranged from leatherette to semi-aniline leather, depending on the trim level.

The 2025 Toyota Sienna, while still resembling a minivan, attempted to add style with its trapezoidal grille and upswept body lines. The Platinum trim level introduced new flower-petal wheel designs. Despite its efforts, the Sienna maintained its minivan appearance, prioritizing practicality over fashion. The test vehicle, a Platinum model, featured a new woodgrain finish in the interior, which received mixed reviews. The Sienna's interior was updated for 2025, with the Platinum trim offering upscale features. However, some passengers found the interior materials less appealing. Overall, the Sienna aimed to balance practicality with a touch of style.

The 2025 INFINITI QX80 was powered by a new twin-turbocharged 3.5-liter V6 engine, replacing the previous 5.6-liter V8. This engine produced 450 horsepower and 516 pound-feet of torque, offering more power than the outgoing V8. A nine-speed automatic transmission replaced the old seven-speed, with rear-wheel drive standard and four-wheel drive optional. The new engine and transmission combination provided a more energetic driving experience, although the active sound enhancement added an artificial noise during acceleration. The QX80 featured air suspension and adaptive damping, allowing for adjustments in ride height and damper firmness. Despite its improvements, the QX80's handling remained average for a large body-on-frame SUV.

The 2025 Toyota Sienna featured a hybrid powertrain with a 2.5-liter four-cylinder engine and a continuously variable transmission (CVT). It offered 245 net horsepower, which was modest for a vehicle seating up to eight and towing up to 3,500 pounds. However, the electric assist motor provided immediate torque, preventing the Sienna from feeling sluggish. The hybrid powertrain prioritized fuel economy, with an EPA rating of 36 mpg in combined driving. The Sienna's handling was predictable but not particularly engaging, with a smooth and absorbent ride. The CVT's droning noise was noticeable during hard acceleration, but the Sienna remained quiet on the highway.

The 2025 INFINITI QX80's redesign increased cargo space by 6%, 17%, and 28% behind the first, second, and third rows, respectively. This resulted in 22 cubic feet with all rows in place, 59 cubic feet with the third row folded, and 101 cubic feet with both the second and third rows folded. The QX80 offered power liftgate and power-folding second- and third-row seats, making reconfiguring the interior easy. Passenger space was generous, with increased legroom in the first and third rows. The QX80 had a maximum towing capacity of 8,500 pounds, surpassing most full-size luxury SUVs.

The 2025 Toyota Sienna focused on form and function, offering power-adjustable, heated, and ventilated front seats. The second-row captain's chairs with ottoman-style leg rests were popular with passengers, and the third-row seat accommodated adults comfortably. The Sienna provided 33.5 cubic feet of cargo space behind the third row, expanding to 75.2 cubic feet with the third row stowed. Maximum cargo capacity was 101 cubic feet, less than rivals due to the non-removable second-row seats. The Sienna's design prioritized ease of use, with sliding side doors and a hands-free power liftgate.

The 2025 INFINITI QX80 featured dual 14.3-inch screens, one for the instrument cluster and the other for the infotainment system. A smaller 9-inch touchscreen handled additional controls. The QX80 was the first Infiniti model with Google built-in apps, including Google Maps, Google Assistant, and the Google Play Store. Wireless Apple CarPlay and Android Auto were also supported. The QX80 offered Klipsch sound systems, with higher trims featuring a 24-speaker version. A 360-degree camera system, digital rearview camera, dash cam, and in-car camera were available.

The 2025 Toyota Sienna's higher-spec models featured a 12.3-inch digital instrumentation panel and a 12.3-inch touchscreen for the Toyota Audio Multimedia (TAM) system. The Platinum trim included a four-zone automatic climate control system, a 10-inch head-up display, and a digital rearview mirror. The TAM system offered various connected services plans, with a digital assistant responding to voice commands. The Sienna Platinum featured a 12-speaker JBL premium audio system, although the sound quality was affected by excessive bass. The four-zone climate control system and digital rearview camera were appreciated by passengers.

The 2025 INFINITI QX80's crash-test ratings were unavailable at the time of publication. Standard safety features included forward collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, lane-departure warning, and a trailer blind-spot warning system. The QX80 offered Nissan's ProPilot Assist highway-driving assistance system, with adaptive cruise control and automated lane centering. The more advanced ProPilot Assist 2.1 version allowed for hands-free driving and automated lane changes.

The 2025 Toyota Sienna featured Toyota Safety Sense (TSS) 2.0, which included forward collision warning, automatic emergency braking, pedestrian detection, lane departure warning, lane-keeping assist, lane-centering assist, and adaptive cruise control. The Sienna also had blind-spot monitoring and rear cross-traffic alert. The Sienna's TSS 2.0 provided a more straightforward driving experience compared to TSS 3.0. The Sienna received a five-star overall rating from the National Highway Traffic Safety Administration (NHTSA), but its frontal crash-test result was four stars, and it scored three stars for driver protection in a frontal impact.
