Mercedes-Benz GLS vs Toyota RAV4 Plug-in Hybrid

The 2026 Mercedes-Benz GLS was a luxurious SUV that offered a range of models, including the GLS 450, GLS 580, AMG GLS 63, and Maybach GLS 600, with prices spanning from $91,600 to $181,350. Our test vehicle, the GLS 450, featured the new Manufaktur Edition Package, which added 21-inch AMG wheels, the AMG Line Exterior Package, the Night Package, and the Exclusive Package. These enhancements included massaging front seats, heated second-row captain’s chairs, and premium leather upholstery. The GLS 450's interior was reminiscent of the smaller GLE-Class, boasting high-quality materials and a sophisticated design. However, it did exhibit some body creaks on cold mornings. The dual 12.3-inch displays were well-integrated, and the control layout, though idiosyncratic, was easy to acclimate to.

The 2026 Toyota RAV4 Plug-in Hybrid was available in the Rugged Woodland trim and three Sport grades: SE, XSE, and the new GR Sport. The RAV4 PHEV maintained the same footprint as its predecessor but featured design tweaks like buffer bumpers and a more truck-like presence. The Woodland trim emphasized off-road capabilities with features like all-terrain tires and a black roof rack, while the GR Sport showcased racier elements such as red brake calipers and a wide mesh grille. The interior offered clever storage solutions, and the seating was comfortable, though the panoramic sunroof reduced headroom slightly. The RAV4 PHEV's cargo space was slightly reduced compared to the standard model, but it still provided ample room for most needs.

The 2026 Mercedes-Benz GLS 450 was powered by a turbocharged 3.0-liter inline-six engine with mild-hybrid assist, delivering 375 horsepower and 369 pound-feet of torque. Paired with a nine-speed automatic transmission and standard 4Matic all-wheel-drive, it accelerated from 0-60 mph in an estimated 5.8 seconds. The GLS 450 offered a tailored driving experience with a maximum towing capacity of 7,700 pounds. Its Airmatic adaptive suspension contributed to a smooth ride, although the powertrain occasionally exhibited delays in responsiveness. The GLS excelled in urban and suburban environments, offering a quiet cabin and composed ride.

The 2026 Toyota RAV4 Plug-in Hybrid featured an updated 2.5-liter inline four-cylinder engine, producing 186 horsepower, and a larger 22.7-kwh battery pack. The PHEV's total power output increased to 324 horsepower, making it the most powerful RAV4 to date. It offered an estimated electric range of 52 miles and a 0-60 mph time in the low five seconds. The RAV4 PHEV's handling was enhanced by a strengthened chassis and improved suspension, particularly in the GR Sport trim. The transition between power sources was seamless, and the vehicle provided a spirited ride without sacrificing comfort.

The 2026 Mercedes-Benz GLS offered standard seven-passenger seating, with a six-passenger configuration available. The interior was exceptionally comfortable, with features like a four-zone climate control system and heated and ventilated front seats. The Manufaktur Edition Package added fabric pillows to the front-seat head restraints, which were not well-received. The GLS provided generous legroom, although the seating position was low. Cargo space was ample, with 17.4 cubic feet behind the third row and up to 84.7 cubic feet with the second row folded down.

The 2026 Toyota RAV4 Plug-in Hybrid's interior was optimized for storage, with clever features like a dashboard shelf and deep door pockets. The SE trim offered a power driver’s seat and heated front seats, while higher trims added ventilated seats and synthetic leather upholstery. The RAV4 PHEV's passenger space was comfortable, with 37.8 inches of rear legroom. Cargo space was slightly reduced compared to the standard RAV4, offering 33.6 cubic feet behind the rear seats and 63.5 cubic feet with the seats folded down.

The 2026 Mercedes-Benz GLS featured dual 12.3-inch displays with the Mercedes-Benz User Experience (MBUX) infotainment system. It included wireless Apple CarPlay and Android Auto, a navigation system with augmented reality, and a standard Burmester surround-sound system. The MBUX system was user-friendly, with a digital assistant that responded to voice commands. However, it occasionally struggled with specific requests.

The 2026 Toyota RAV4 Plug-in Hybrid boasted a new 12.3-inch digital instrument cluster and an enhanced 10.5-inch touchscreen system. The touchscreen featured customizable tiles and a quick menu for easy navigation. The RAV4 PHEV's operating system, Arene, was more responsive, and the Voice Assistant handled a wide range of commands. A built-in dash cam was a noteworthy addition, offering recording capabilities from the exterior cameras.

The 2026 Mercedes-Benz GLS came equipped with nearly 40 safety and driver-assistance systems, including Pre-Safe, Crosswind Assist, and Active Emergency Stop Assist. It featured a surround-view camera system and a hands-on driver-assistance system. However, the GLS required active driver participation, and its curve-speed reduction technology was overly cautious.

The 2026 Toyota RAV4 Plug-in Hybrid included Toyota Safety Sense 4.0, offering a comprehensive suite of driver-assistance features. The system featured automatic emergency braking, lane-departure alert, adaptive cruise control, and blind-spot monitors. The RAV4 PHEV's safety enhancements aimed to improve responsiveness and detection, although crash-testing results were pending.
