5.0 L 32-V DOHC V-8 Engine with dual VVT-i – The primary power
source for your vehicle, the engine works in conjunction with the hybrid
battery to deliver power to the ECVT.
Electric Starter Motor/Generator (MG1) - Serves as the starter motor
for the engine and a “pathway” for the engine’s power to reach the wheels.
Electric Drive Motor /Generator (MG2) – Delivers power to the rear
wheels. It can run alone or with the engine. It is driven by electrical power
from MG1 and/or the hybrid battery. During braking or deceleration, it
generates electricity to recharge the hybrid battery.
Hybrid Battery – Composed of sealed nickel-metal hydride modules, the
288-volt hybrid battery is located in the trunk between the rear wheels.
It supplies power to the electric drive motor during start-up, acceleration,
uphill driving, and reverse. It supplies power to the Inverter for use by the
electric motors and stores regenerative energy captured during coasting
and braking conditions.
