All Sienna trims come with a 3.5-liter V6 engine (296 horsepower, 263 lb-ft of torque) paired with an eight-speed automatic transmission. All-wheel drive is optional on every trim level except the L. Depending on the configuration and trim, the Sienna seats either seven or eight passengers.
Standard features for the base L include 17-inch alloy wheels, automatic headlights, a wiper de-icer, tri-zone automatic climate control, keyless entry, a rearview camera, a conversation mirror, Bluetooth, a 7-inch touchscreen with Toyota’s Entune interface, Apple CarPlay smartphone integration, five USB ports, and a six-speaker sound system with a CD player, media player interface and an auxiliary audio jack.
Toyota Safety Sense, or TSS-P, also comes standard starting with L trims. It includes forward collision warning with pedestrian detection, automatic emergency braking, lane departure warning, and lane keeping assist, adaptive cruise control and automatic headlights.
The LE adds roof rails, power-sliding rear doors, privacy glass, heated mirrors, a power-adjustable driver’s seat, upgraded easy-clean fabric upholstery, and rear sunshades. All-wheel-drive versions also get 18-inch wheels.
The SE is equipped similarly to the LE but adds a sport-tuned suspension, sharper steering, 19-inch alloy wheels (18-inch for all-wheel-drive models), and sportier exterior styling. The SE also has a power liftgate, first- and second-row leather upholstery (the third row gets premium vinyl), heated front seats, and unique gauges with a larger driver information screen.
The SE Premium adds a sunroof, keyless ignition and entry, blind-spot monitoring and rear cross-traffic alert systems, a navigation system, a premium JBL sound system, a rear-seat entertainment system, and the Driver Easy Speak system, which amplifies the driver’s voice through the rear speakers.
New for 2020, the SE’s optional Nightshade package adds black-painted exterior elements, including the grille, wheels, door handles and mirrors. Even the badging is blacked out.
The Sienna XLE shares many of the SE trim’s comfort and convenience equipment, but it features similar suspension, steering and styling to the LE. It also adds a power-adjustable front passenger seat, imitation-wood trim, power-opening rear-quarter windows, and keyless ignition and entry. The XLE Premium adds the SE Premium’s features and rear parking sensors.
The plush Limited includes the XLE Premium’s features (minus the rear entertainment system), along with 18-inch alloy wheels, a different grille, LED daytime running lights, auto-dimming and power-folding mirrors, front and rear sunroofs, and front and rear parking sensors. Inside is premium leather upholstery on the first and second rows, driver-seat memory functions, and a heated steering wheel.
Front-wheel-drive models also get a sliding center console between the first two rows, extendable footrests for the second row, and a power-folding third row with faux leather upholstery.
You can add even more with the Limited Premium trim, which tacks on xenon headlights, automatic wipers, a surround-view parking camera system, the rear-seat entertainment system, and upgraded third-row leather (AWD only).
