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. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Honda Odyssey doesn’t offer height-adjustable middle seat belts.

The Sienna has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Odyssey doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Sienna XLE/XSE/Limited/Platinum/25th Anniversary Edition has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Odyssey doesn’t offer backup collision prevention brakes.

The Sienna offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Odyssey doesn’t offer all-wheel drive.

The Sienna Platinum has a standard Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Odyssey only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The Sienna’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Odyssey doesn’t offer a driver alert monitor.

Both the Sienna and the Odyssey have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Toyota Sienna is safer than the Honda Odyssey:

	Sienna	Odyssey
	Front Seat
STARS	5 Stars	5 Stars
HIC	42	66
Chest Movement	.5 inches	.5 inches
	Rear Seat
STARS	5 Stars	5 Stars
HIC	52	125
Spine Acceleration	30 G’s	70 G’s
Hip Force	542 lbs.	709 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	12 inches
Spine Acceleration	31 G’s	41 G’s

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Toyota Sienna is safer than the Odyssey:

	Sienna	Odyssey
Overall Evaluation	GOOD	GOOD
Structure	GOOD	GOOD
	Driver Injury Measures
Head/Neck	GOOD	GOOD
Torso	GOOD	GOOD
Shoulder Deflection	.55 in	.87 in
Shoulder Force	178 lbs.	223 lbs.
Torso Max Deflection	.83 in	1.26 in
Pelvis	GOOD	GOOD
Head Protection	GOOD	GOOD
	Passenger Injury Measures
Head/Neck	GOOD	GOOD
Head Injury Criterion	18	142
Neck Compression	22 lbs.	67 lbs.
Torso	GOOD	ACCEPTABLE
Torso Max Deflection	.71 in	1.81 in
Torso Deflection Rate	7 MPH	11 MPH
Pelvis	GOOD	ACCEPTABLE
Pelvis Force	625 lbs.	915 lbs.
Head Protection	GOOD	GOOD

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Sienna its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 134 vehicles tested by the IIHS. The Odyssey is only a standard “Top Safety Pick” for 2019.

The Sienna Platinum has a standard heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Odyssey doesn’t offer a heads-up display.

The power windows standard on both the Sienna and the Odyssey have locks to prevent small children from operating them. When the lock on the Sienna is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Odyssey prevents the driver from operating the rear windows just as it does the other passengers.

The Sienna’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Odyssey’s standard halogen headlights. LED lights also light instantly and last over twenty times longer than halogen.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Sienna’s headlights were rated “Good” by the IIHS, while the Odyssey’s headlights are rated “Acceptable.”

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Sienna has standard extendable sun visors. The Odyssey doesn’t offer extendable visors.

Both the Sienna and the Odyssey offer available heated front seats. The Sienna Platinum also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the Odyssey.
