Deep Dive: Chrysler Pacifica Hybrid Transaxle (w/ Video)

Chrysler Pacifica Hybrid

The new-for 2017 Chrysler Pacifica hybrid represents the first mainstream attempt to bring hybrid technology to the North American minivan market. Part of what makes the trend-setting minivan so unique is its innovative Si-EVT Hybrid yransmission.

All those letters in the Chrysler Pacifica Hybrid tranny nomenclature stand for Single-input (Si) Electronically Variable Transaxle (EVT), which tells you a few things right off the bat. Namely, that there’s a single power input and that it features some sort of CVT that uses electronics, rather than inertia/rpm alone, to select its gear ratios. Which, I mean, those are fine things to know if you want a basic overview of the van Kyle considered calling “perfect” when he wrote about it earlier this month- but if you’re a tech nerd (and I’m a tech nerd), you might find yourself wanting more.

That’s what this hour-plus long deep dive from Weber State University’s automotive technology department comes in. You can get into the hows and why’s of the new Chrysler Pacifica Hybrid transmission is all about, and how it contributes to the van’s awesome 84 MPGe fuel economy rating, below. Enjoy!
