Toyota Sienna Curb Weight: 4,621 lbs to 4,740 lbs

At 55/45, the 4,621 lbs puts about 2,541 lbs on the front axle and 2,080 lbs on the rear — 461 lbs more over the front wheels, which is what front tires and front brake pads wear against first.

The two axles are not the same width either: 67.7 in of track at the front against 68.5 in at the rear, 0.8 in narrower in front.

The lightest 2015 record is 4,277 lbs; the lightest 2026 record is 4,621 lbs — 344 lbs heavier (8.0%).

At the top of the range the 2026 file reaches 4,740 lbs against 4,663 lbs in 2015, a 77 lbs increase — driven by which configurations exist, not by the same truck gaining mass.

Every body style recorded in both drive layouts gains exactly 119 lbs moving from two-wheel to four-wheel drive — about 2.6% of the two-wheel-drive figure.

The published 18-gallon tank holds about 110 lbs of gasoline at 6.1 lb per gallon, and curb weight is measured with it full. Run it to empty and the Minivan AWD is effectively a 4,630 lbs vehicle — 2.3% of the figure quoted above is fuel you will burn off.

With a With Tow Package configuration, the 2026 Sienna is rated to pull 3,500 lbs — 0.7 times the 4,740 lbs the heaviest recorded truck weighs by itself, and 0.8 times the 4,621 lbs of the lightest.

That rating belongs to the With Tow Package build, not to every truck on this page: a Minivan AWD starts 119 lbs deeper into the combined rating than a Minivan FWD before a trailer is coupled.
