Overview of the First Generation Toyota Sienna
The first-generation Toyota Sienna, introduced in 1998, revolutionized minivans with its design, fuel efficiency, and safety features. The 2001 update enhanced its performance and safety, maintaining its competitive edge in the segment against rivals like Hyundai Odyssey, thanks to its innovative features and reliable performance.

Introduced in 1998, the Toyota Sienna marked a significant milestone, earning the nickname "Camry of minivans" for its innovative design. Built on an extended platform similar to the popular Toyota Camry, it replaced the Previa with a front-wheel-drive setup. The name "Sienna" originates from Italy's Sienna town. Available in CE, LE, and XLE trims, it offered impressive fuel efficiency of 16 mpg city and 22 mpg highway, making it a top choice in its segment.
Over time, the Sienna received updates to stay competitive. The 2001 model featured redesigned taillights, bumpers, and significant engine enhancements with variable valve timing for increased torque. Interior updates included revamped HVAC controls, with the CE model having a two-passenger bench, and LE/XLE models equipped with captain's chairs. Standard features included a sliding door on the driver's side and removable seating.
Safety was a highlight, with side torso airbags and superior crash test ratings, outperforming the Previa. It earned a five-star rating in frontal crash tests and four stars for side impacts, as per the Insurance Institute for Highway Safety. During this era, Hyundai’s Odyssey was a notable competitor offering comparable features.
