What kind of drive is a 2016 Toyota Sienna?
The 2016 Sienna is a front‑engine minivan available with front‑wheel drive as standard and an optional Intelligent All‑Wheel Drive system.
Drivetrain options for the 2016 Sienna
Two drivetrain configurations were available for the year, covering most buyers' needs:
- Front‑Wheel Drive (FWD) — standard on most trims; the engine powers the front wheels through a transaxle.
- Intelligent All‑Wheel Drive (AWD) — optional on most trims; an electronically controlled clutch and rear axle distribute torque to the rear wheels as needed for traction.
For daily driving, FWD is typically sufficient and more fuel‑efficient. AWD adds traction in wet or snowy conditions, but can slightly reduce fuel economy and raise the purchase price.
How the drive systems work
Front‑Wheel Drive (FWD)
In FWD configuration, the 3.5‑liter V6 sends power to the front wheels via a transaxle mounted to the front of the vehicle. This setup is common for minivans, offering straightforward handling, good efficiency, and lower maintenance complexity compared with all‑wheel systems.
Intelligent All‑Wheel Drive (AWD)
Intelligent AWD uses a rear differential and an electronically controlled clutch to send torque to the rear wheels when traction is needed. The system operates automatically, typically defaulting to front‑wheel bias and engaging the rear wheels under slip or slick surface conditions to improve stability.
Performance and economy considerations
Engaging AWD can modestly impact fuel economy and upfront cost compared with the standard FWD. In normal dry conditions, the system largely operates in FWD, conserving energy while still providing traction when required.
Summary
The 2016 Toyota Sienna offers two drivetrain configurations: standard Front‑Wheel Drive and an optional Intelligent All‑Wheel Drive. FWD suits most daily driving needs and tends to be more economical, while AWD provides enhanced traction in adverse weather. Both configurations pair a 3.5‑liter V6 with a 6‑speed automatic transmission, delivering practical versatility for a family minivan.
