Toyota has sold more than 2.2 million Sienna models since its debut in 1997. The fourth-generation Sienna debuted for the 2021 model year, offering hybrid power exclusively and giving customers the benefit of Toyota’s 20+ years of global hybrid leadership and well-documented quality, durability, and reliability. The 2023 Sienna lays down impressive numbers. Its Toyota Hybrid System II delivers 245 total system horsepower and earns the vehicle a manufacturer-estimated 36 combined MPG fuel economy (front-wheel drive).
