What Our Members Are Saying about the Powertrain of the 2018 Toyota Sienna

2018 Toyota Sienna Powertrain: Pros
YearBody/PowertrainComment
2017 4dr Minivan, ext. 296-horsepower 3.5L V6
8-speed shiftable automatic FWD		 The 2017 Sienna comes with an 8-speed transmission - I preferred the 6 speed that came in our SE model. Not sure it's because our van is new and perhaps the transmission hasn't "learned" how we drive but the shifts aren't as seamless as before. There's a bit of gear "hunting" when slowing down then accelerating (ie. coming to a near stop but the light turns green). Going up a hill, the transmission stayed in gear up to 4,000 rpms despite me easing off the accelerator in hopes of the transmission would shift to a higher gear. Once at cruising speed, the rpm is noticeably low. At 75 mph, rpms was just shy of 2,000 rpm! Must be that 8th gear. We haven't taken our van on a roadtrip yet so not sure if the lower rpm would equate to better mpg's. Acceration from a stop isn't as immediate at our 2013 Odyssey (Touring), once at speed however, the Sienna moves! see full Toyota Sienna review
