Why is it that my 2WD Toyota Sienna handles better in snow or ice than my Ram 2500 also a 2 WD?

Toyota Sienna Snow

Simply because your 'Ram' is rear wheel drive as compared to the front wheel drive Toyota,

You will almost certainly find the pickup will handle snow better with some load on board.

The Sienna is a front-wheel drive van. It's pulling the car forward, rather than pushing it, using the wheels with the most weight over them (since the engine is in the front). Both of these things improve handling in slick conditions, e.g. rain and ice.

The Ram is a rear-wheel drive pickup. It pushes rather than pulls, which amplifies traction problems and causes things like fishtailing when you're on slick surfaces. In addition, pickups have even less weight in the rear than other vehicle types, which makes this problem even worse. While this, on its face, would make you think "then why the hell would you make a truck like this," it IS better when towing or hauling heavy loads in normal driving conditions as compared to front wheel drive vehicles.

Reader's Digest version: because the van is front wheel drive and front-wheel drive cars handle slick road conditions better.

The van is front wheel drive, the engine sits over the drive wheels adding weight so it gives the van more traction in snow/ice. The pickup isn't as good because there isn't much weight over the rear wheels the majority of the weight is in the front where the engine is. Throw a few hundred pounds of weight in the back of your pickup and you'll see a huge difference in how it operates in snow/ice.

Hi as we say nothing handles like a toyota.

Front-drive will be better in snow since most of the vehicles weight are over the drive wheels.However, it has another advantage...The drive wheels are the steering wheels.

The Toyota is front wheel drive and weight distribution matters. The truck is rear wheel drive and is way front heavy

fwd and rwd make a difference. fwd, the car front wheels are pushing forward compared to rwd

Because the Sienna is FRONT WHEEL DRIVE SNOWFLAKE!!

Huh?
