The 2021 Toyota Sequoia model line consists of SR5, TRD Sport, Limited, TRD Pro, Platinum and Nightshade models. All models get a 381-horsepower, 5.7L i-Force V8 rated at 13 mpg city and 17 mpg highway for both RWD and four-wheel-drive Sequoias. The optional 4-wheel-drive system includes a 2-speed transfer case with a true low range good for serious off-roading and other heavy-duty tasks, while a Torsen limited-slip differential helps distribute power in a predictable, steady manner. Switching between the system's modes only involves turning a simple dash-mounted knob. Thanks to a 4-wheel independent suspension and tubular anti-roll bars, the Sequoia rides and handles quite well. An air suspension on the Platinum Sequoia further improves comfort and towing. The Platinum also includes 20-inch wheels. Stopping power is good, even when the Sequoia is fully loaded, thanks to big 4-piston anti-lock disc brakes with brake assist. Electronic stability control helps maintain safety for abrupt maneuvers or on slippery surfaces. Proof that the Sequoia was built to handle demanding towing tasks, the SUV's tow hitch is integrated into the frame. This allows tow ratings to range as high as 7,400 pounds, and the transmission includes a tow/haul mode to utilize engine braking. Eight-passenger seating is standard on the Sequoia in the form of three rows and an option for second-row captain's chairs setup is available. The second-row slides fore and aft to optimize comfort between rows and aid access, and in models with the bench seat, it's split 40/20/40 for the best combination of people and cargo. The third row is split 60/40 and can recline or fold flat. Behind the third row there's a rear power window and a power liftgate is available. Additional safety features on the Sequoia include all-row Roll-sensing Side Curtain Airbags (RSCA) on 4X4 models, front-seat side airbags and now, knee airbags for front occupants. One of the best things about the Sequoia is that although it wears a Toyota badge, it has an interior well-equipped enough to feel like a Lexus. The extensive standard-equipment list includes a 3-zone climate control system, a sunroof, front and rear parking sensors, Smart Key keyless entry, Dynamic Radar Cruise control and Entune Audio Plus, which features an 8-speaker HD Radio and Sirius XM satellite radio system, Bluetooth, and MP3 compatibility. The Limited trim adds heated leather 10-way power-adjustable seats, a 12-speaker sound system and other upgrades. At the top of the range, the Platinum adds 20-inch diamond cut-finish alloys, the load-leveling air suspension, a 15-speaker JBL sound system, memory driver's seat, ventilated front seats and second-row heated seats and a rear-seat Blu-ray entertainment system.
