About the 2018 Toyota Sienna

3rd generation Sienna (2011-2020), late-cycle refresh year after the earlier facelift.

Toyota positions the Sienna as a family van built around real-world usefulness: roomy seating, flexible cargo space, sliding doors, strong V6 power and rare AWD availability in this class. The emphasis is less on flashy luxury and more on making daily family duty easier, from road trips to school runs to hauling bulky cargo. Versus many rivals, Toyota leans on safety, proven V6 performance, practical interior flexibility and the availability of AWD versions.

The 2018 Sienna ranges from the straightforward seven-passenger L to family-focused LE and leather-trimmed XLE versions. The SE adds firmer suspension tuning and sportier styling, while Limited and Limited Premium emphasize comfort with features such as premium leather, upgraded JBL audio and dual moonroofs. Several upper trims also feature a wide-screen rear entertainment system for family trips.

“Toyota Sienna is an older design which has retained the more old school luxury in the interior while having the latest active safety features. If Lexus made a minivan, I think it would look very close to our Sienna. Bulletproof Toyota reliabilty over the extended life (planned 200K miles) of the vehicle.”
