Comparison of Energy Use
(10-15 Mode)
We have been developing compact, highly efficient drive systems for EVs and hybrid vehicles by combining
our experience and know-how as a specialized maker of automatic transmissions with state-of-the-art motor
technology.
Our EV drive system program began with the development of a four-wheel electric car in 1986 and continued
as Toyota selected our EV drive system for the Crown Majesta EV in1993. In 1998, we produced an EV
system for Toyota's "e-com," an ultra-compact EV.
The system was also used as the drive system for a super-compact EV (Coms) sold by Toyota Auto Body
from 2000 to 2011.
For hybrid vehicle drive systems, which have been attracting increased attention recently, we are producing
two 2-motor hybrid systems for FF vehicles and two for FR vehicles.
AISIN AW's contribution to society originates in the development of forward-looking, environmentally
responsible automobiles. Our drive systems for EV and hybrid vehicles help reduce exhaust gases and improve
fuel economy.

FF 2-motor hybrid transmission
●
The Toyota Camry Hybrid features an AW FF 2-motor
hybrid transmission.
●
The Toyota Prius, which has lower capacity than the
Camry Hybrid, features an AW FF 2-motor hybrid
transmission.
●
The system is featured in the Lexus
GS450h, which was launched in
March 2006, and the Toyota Crown
Hybrid, which was launched in May 2008.
●
Lexus selected an AISIN AW 4WD
hybridztransmission featuring
improved quietness for use in its
flagship LS600h (available May 2007).
RWD 2-motor Hybrid Transmission / 4WD Hybrid Transmission
This 2-motor hybrid system delivers improved fuel economy without sacrificing the power and speed that are
expected of a luxury passenger car. A double reduction design that can select from two reduction gear ratios
for the drive motor output shaft enabled a design that was compact enough to be integrated into existing
RWD platforms.
This 2-motor hybrid transmission combines the advantages of series hybrid and parallel hybrid architectures to
achieve optimal engine operation and super-high fuel efficiency through brake energy recovery and other
means.
