2022 Toyota Sienta III 1.5 (116 Hp) Hybrid E-Four E-CVT

The Toyota Sienta III 1.5 Hybrid E-Four E-CVT represents the third generation of the Sienta, a compact minivan primarily marketed in Japan and other Asian markets. Introduced in August 2022, this iteration builds upon the Sienta’s reputation for maximizing interior space within a small footprint, coupled with Toyota’s renowned hybrid technology. While not officially sold in the United States, the Sienta occupies a unique niche as a practical and fuel-efficient family vehicle, offering a compelling alternative to larger, more conventional SUVs and minivans. The “E-Four” designation indicates an all-wheel-drive system utilizing an electric motor to power the rear wheels, enhancing traction and stability.

Toyota Sienta III: A Detailed Overview

The Sienta has always been a vehicle designed with urban environments in mind. The third generation continues this trend, focusing on ease of use, fuel efficiency, and a surprisingly spacious interior for its size. It caters to families and individuals who prioritize practicality and maneuverability over outright performance. The hybrid powertrain is central to its appeal, offering significant fuel economy benefits and reduced emissions. The E-Four system differentiates this model, providing all-weather capability and improved handling characteristics.

Engine & Performance

The Toyota Sienta III 1.5 Hybrid E-Four is powered by a 1.5-liter, inline-three-cylinder gasoline engine (M15A-FXE) producing 91 horsepower at 5500 rpm and 120 Nm (88.51 lb-ft) of torque between 3800-4800 rpm. This engine is paired with Toyota’s Hybrid Synergy Drive system, incorporating two electric motors. The primary electric motor delivers 80 horsepower and 141 Nm (104 lb-ft) of torque, while a secondary, smaller electric motor located on the rear axle contributes 3 horsepower and 44 Nm (32.45 lb-ft) of torque. The combined system output is 116 horsepower. Power is delivered to all four wheels via an electronically controlled continuously variable transmission (E-CVT). This configuration allows for seamless transitions between gasoline engine power, electric motor power, or a combination of both, optimizing fuel efficiency and performance. The weight-to-power ratio is 11.9 kg/Hp, and the weight-to-torque ratio is 11.5 kg/Nm. The vehicle’s Start & Stop System further contributes to fuel savings by automatically shutting off the engine when the vehicle is stationary.

The E-Four model benefits from the added stability and traction provided by its all-wheel-drive system. Safety features include ABS (Anti-lock Braking System) and a comprehensive suite of driver-assistance technologies, reflecting Toyota’s commitment to safety. The Sienta’s compact dimensions make it easy to maneuver in congested urban environments, while its spacious interior provides ample room for passengers and cargo.
