Consumer Reports

Suspension and Handling Comparison

For superior ride and handling, the Honda Odyssey has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Toyota Sienna has a rear torsion beam axle, with a semi-independent rear suspension.

The Odyssey has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Sienna doesn’t offer variable-assist power steering.

For better maneuverability, the Odyssey’s turning circle is .7 feet tighter than the Sienna AWD’s (36.7 feet vs. 37.4 feet). The Odyssey’s turning circle is .8 feet tighter than the Sienna’s (36.7 feet vs. 37.5 feet).

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the Odyssey has an electronically controlled liquid-filled engine mounts. A computer controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The Sienna uses conventional solid rubber engine mounts.

The Odyssey uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Sienna doesn’t offer active noise cancellation.

Passenger Space Comparison

The Odyssey has 8.2 cubic feet more passenger volume than the Sienna (172.6 vs. 164.4).

The Odyssey has .4 inches more front legroom, 3.3 inches more rear legroom and 6.1 inches more third row legroom than the Sienna.

The front step up height for the Odyssey is 1.7 inches lower than the Sienna (15” vs. 16.7”). The Odyssey’s rear step up height is 2 inches lower than the Sienna’s (17” vs. 19”).

Ergonomics Comparison

If the windows are left down on the Odyssey the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Sienna can only operate the windows from inside the vehicle, with the ignition on.

The Odyssey’s power mirror controls are mounted on the armrest for easy access. The Sienna’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

The Odyssey Touring/Touring Elite has a standard center folding armrest for the third row rear passengers. A center armrest helps make rear passengers more comfortable. The Sienna doesn’t offer a third row rear seat center armrest.

Bluetooth wireless connectivity is standard on the Odyssey, connecting the driver and passenger’s cell phones to the vehicle systems. This allows them to use the vehicle’s stereo and hand controls to place calls safely and easily. Toyota doesn’t offer wireless connectivity on the Sienna L.

Economic Advantages Comparison

Insurance will cost less for the Odyssey owner. The Complete Car Cost Guide estimates that insurance for the Odyssey will cost $375 less than the Sienna over a five-year period.

The Odyssey will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the Odyssey will retain a greater percentage of its original price after three and five years than the Sienna.
