Compare the2023 Mercedes Metris PassengerVS 2023 Toyota Sienna

Both the Metris Passenger and the Sienna have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, rearview cameras, driver alert monitors, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

The Metris Passenger’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Sienna LE/XLE’s standard 65 series tires.

The Metris Passenger has a standard full size spare tire so a flat doesn’t interrupt your work or a trip. A full size spare isn’t available on the Sienna; it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.

The Metris Passenger’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Sienna doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Metris Passenger’s wheelbase is 5.5 inches longer than on the Sienna (126 inches vs. 120.5 inches).

For better maneuverability, the Metris Passenger’s turning circle is 1.9 feet tighter than the Sienna’s (36.4 feet vs. 38.3 feet). The Metris Passenger’s turning circle is 2.8 feet tighter than the Sienna XSE/Limited/Platinum FWD’s (36.4 feet vs. 39.2 feet).

The Mercedes Metris Passenger may be more efficient, handle and accelerate better because it weighs about 200 to 400 pounds less than the Toyota Sienna.

The Metris Passenger has .2 inches more front shoulder room, 1.5 inches more rear headroom, 2.2 inches more rear shoulder room, 3.1 inches more third row headroom, 7.2 inches more third row hip room and 2.7 inches more third row shoulder room than the Sienna.

The Metris Passenger’s cargo area provides more volume than the Sienna.

The Sienna’s spare tire is stored in the cargo area, where it diminishes the useable cargo capacity and interferes with loading and unloading. The Metris Passenger’s spare is out of the way underneath.

The Metris Passenger’s optional rear cargo window opens separately from the rest of the double swing out door to allow quicker loading of small packages. The Sienna’s rear cargo window doesn’t open.

The Metris Passenger’s standard towing capacity is much higher than the Sienna’s (5000 vs. 3500 pounds).

The Metris Passenger has a much higher standard payload capacity than the Sienna AWD (1720 vs. 1375 lbs.).

The Metris Passenger has a much higher optional payload capacity than the Sienna (1720 vs. 1420 lbs.).

The engine in the Metris Passenger is mounted longitudinally (North-South), instead of sideways, as in the Sienna. This makes it easier to service and maintain, because the accessory belts are in front.

Heated windshield washer nozzles are optional on the Metris Passenger to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Sienna doesn’t offer heated windshield washer nozzles.

The Metris Passenger’s optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Sienna doesn’t offer an automated parking system.
