For enhanced safety, the front and middle seat shoulder belts of the Toyota Sienna are height-adjustable to accommodate a wide variety of driver and passenger heights.

To lower fuel costs and make buying fuel easier, the Toyota Sienna uses regular unleaded gasoline. The CX-90 PHEV requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Sienna higher (6 out of 10) than the Mazda CX-90 (5 to 6). This means the Sienna produces up to 6.9 pounds less smog-producing pollutants than the CX-90 every 15,000 miles.

The Sienna has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The CX-90 doesn’t offer a CVT.

The Sienna’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the CX-90 are solid, not vented.

The Sienna stops shorter than the CX-90:

For better handling and stability, the track (width between the wheels) on the Sienna is .6 inches wider in the front and 1.2 inches wider in the rear than on the CX-90.

The Toyota Sienna may be more efficient, handle and accelerate better because it weighs about 250 to 500 pounds less than the Mazda CX-90.

The Sienna has 20.9 cubic feet more passenger volume than the CX-90 (162.5 vs. 141.6).

The Sienna has .4 inches more front headroom, 3.4 inches more front hip room, 5.2 inches more front shoulder room, .5 inches more rear legroom, 10.7 inches more rear hip room, 4.6 inches more rear shoulder room, .5 inches more third row headroom, 8.3 inches more third row legroom, 5.1 inches more third row hip room and 5.2 inches more third row shoulder room than the CX-90.

The Sienna’s cargo area provides more volume than the CX-90.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Sienna. The CX-90 doesn’t offer locking storage for small valuables.

If the windows are left open on the Sienna the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the CX-90 can only close the windows from inside the vehicle, with the ignition on.

The Sienna’s standard Smart Key System allows you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Advanced Keyless Entry and Start standard on the CX-90 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The Sienna’s standard sliding doors can be opened with less than three inches side clearance. The CX-90’s standard rear swing-out doors are bulky and make loading in tight spots difficult.

The Sienna’s power side sliding doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the van. The CX-90 doesn’t offer a power rear door.

The Sienna’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The CX-90’s power window (except driver window) switches are unlit, making them difficult to find at night and operate safely.

Its extensive coverage guarantees consistent, crystal-clear reception across the continental U.S., and access to over 100 channels dedicated to a multitude of genres, including music, news, sports, talk shows, and comedy, many with only limited commercial breaks. Satellite radio is only offered on the CX-90 Premium.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota Sienna has a standard wireless phone charging system (Qi) in the center console. Only the CX-90 Preferred/Premium offers wireless charging.
