How the Sienna hybrid system works
Toyota.com lists a hybrid 2.5-liter gas engine with double overhead cams (DOHC), 16 valves, D-4S injection and Dual VVT-i, working with permanent magnet synchronous motors and a sealed nickel-metal hydride (Ni-MH) traction battery. The combined output is listed as 245 net combined hp.
Toyota's 2026 Sienna announcement describes the gas engine as having a 14:1 compression ratio and 41% thermal efficiency, with VVT-iE on the intake camshaft and VVT-i on the exhaust camshaft.
With all-wheel drive, a separate rear electric motor drives the rear wheels; there is no transfer case or driveshaft. Toyota says the system can send up to 80% of torque to the rear wheels on take-off, and that torque distribution varies from 100:0 in constant-speed driving to 20:80 on slippery surfaces.
Every grade uses an electronically controlled continuously variable transmission (ECVT) with sequential shift mode and offers Normal, ECO, EV and Sport drive modes.
