Default Toyota Avalon gets 40-MPG hybrid model for 2013

From AB

All-New 2013 Toyota Avalon Features Both Gasoline and Hybrid

• First Full-Hybrid in the Premium Mid-Size Segment • Avalon Hybrid
Expects a 40-mpg Combined EPA-Rating

TORRANCE, Calif. (June 26, 2012) – When the all-new, North American
designed and engineered 2013 Avalon goes on sale later this year,
consumers can choose between a powerful V6 gasoline powertrain and
Toyota's proven Hybrid Synergy Drive. The efficiency offered by the
new hybrid model will help the all-new premium mid-size sedan achieve
excellent fuel economy with an EPA-rating of 40 mpg combined.

In addition to offering a hybrid powertrain, the new Avalon features a
stunning design, improved dynamic performance, a greater degree of
refinement, and a highly spacious, comfortable interior experience
with an abundance of outstanding convenience technologies.

Powerful, Efficient V6 Engine
The 2013 Avalon will feature a proven 3.5-liter, DOHC V6 engine
coupled with a six-speed automatic transaxle, which has been enhanced
to offer more responsive and efficient performance. The all-aluminum
six-cylinder engine will produce 268 horsepower and 248 lbs. ft. of
torque, which will propel the new sedan to 60 mph in under seven
seconds. Compared to the previous-generation Avalon, this 2013
powertrain combination offers improved fuel economy, performance,
superior shift feel and response, with upgraded drivability and

This enhanced powertrain's programming has been updated to offer ECO,
NORMAL, and SPORT Modes. The ECO mode prioritizes fuel efficiency by
reducing power application at lower speeds and reducing energy
consumed by the air-conditioning system. The SPORT Mode provides
increased acceleration responses though altered engine control unit
(ECU) programming, and it offers a more direct and responsive EPS
programming to enhance steering feel.

In addition, the new transaxle is equipped with a numerically lower
differential gear drive ratio (3.23), designed to help improve fuel
economy. The V6-powered 2013 Avalon achieves an EPA-rated 25 mpg
combined (21 city/ 31 hwy).

The transmission operation has been made more efficient and responsive
with the adoption of a flex-start control feature lock-up clutch. With
lock-up control, the transmission's torque converter fully engages at
a lower RPM during standing starts to improve acceleration response
and help suppress unnecessary engine revolutions. The new transmission
is also kept at an optimal temperature with an automatic-transmission
fluid warmer, helping enhance efficiency.

The multi-mode automatic transmission console shifter offers a D range
and can be moved into an S-mode gate, which allows manually operated
sequential shifting using the console shifter or available (Touring
and Limited models) steering-wheel-mounted paddle shifters. The gear
can be selected by moving the shifter up to (+) position or lower
using the (-) position to experience highly responsive shifts. By
using the paddles or in S-range, the transmission uses a quick
responding shift-logic that includes throttle blipping for downshifts.
The gear changes and range-of-gear selections are displayed in the
color multi-information display.

Avalon Adds Toyota Hybrid Synergy Drive
For consumers seeking a premium mid-size sedan with excellent fuel
economy ratings and an environmental message, the new Avalon features
a full power-split hybrid system. Coupled with reductions in vehicle
weight and improvements in aerodynamics, the Avalon Hybrid is expects
to achieve impressive fuel economy ratings. The 2013 Avalon
incorporates the latest advances in Toyota Hybrid Synergy Drive
technology, building upon Toyota's 14 years of hybrid-development
experience. The Avalon Hybrid features a 2.5-liter, Atkinson-cycle,
four-cylinder engine, a 244.8-volt nickel-metal hydride battery pack,
and a pair of electric motor/generators within the transaxle. A
power-control unit located in the engine compartment houses an
inverter, a DC-DC converter, a step-up converter (raises voltage to a
maximum of 650 volts) and the hybrid-drive ECU, which governs the
seamless operation of electric-motor power application and
regenerative braking. The power control unit relies on liquid cooling
to maintain an efficient temperature.

The Avalon Hybrid achieves a total system output of 200 horsepower and
offers three unique modes of operation: EV, ECO and SPORT. The Avalon
Hybrid models achieve an EPA-rated 40 mpg in the city, and a 39 mpg on
the highway for a combined 40 mpg EPA-rating.

The 2013 Avalon Hybrid offers an EV mode that, under certain
conditions, allows the vehicle to operate solely on electric
propulsion. EV mode can be engaged, provided other conditions are
correct, for up to one mile at speeds up to 25 mph, providing an
all-electric option that is convenient in residential areas or parking

The ECO drive mode engages the gasoline motor, but reduces throttle
response and HVAC output to help improve overall efficiency. The SPORT
Mode takes full advantage of the new Avalon's dynamic character,
improved chassis, and enhanced suspension by altering the engine's
throttle response and enhancing steering feel.

The Avalon's hybrid's battery pack is comprised of 204 cells and is
located in the vehicle trunk behind the rear seats, while still
providing ample trunk space. The scroll casing for the battery cooling
system's blower fan has been designed to produce extremely quiet and
efficient airflow, helping reduce interior noise and elevating
refinement. The power-control unit, located in the engine bay, houses
the inverter, DC-DC converter.

The efficient hybrid transaxle in the new Avalon contains two
high-output electric motor/generators, a power-split device, an open
differential and the final drive ratio. Motor/Generator 1 (MG1) is
used to start the gasoline engine and generate the energy that is
returned to the battery to power the system. Motor/Generator 2 (MG2)
is primarily responsible for electric drivetrain propulsion and
regenerative braking. The hybrid vehicle transaxle also incorporates a
flywheel-damper design that helps reduce noise and vibration during
engine engagement.

Captivating Styling with a Spacious, Luxurious Interior Experience
The new 2013 Avalon is the product of a North American-focused design
and engineering effort. The new sedan's striking exterior and
luxurious interior design was conceived by a youthful, talented team
at the Calty Design Research Inc., facilities in Southern California
and Michigan.

The car's engineering development was led by a passionate and
dedicated group based at Toyota Technical Center in Ann Arbor, Mich.
Continuing a North American focus, the 2013 Avalon will be assembled
at the award-winning Toyota Motor Manufacturing Kentucky (TMMK)
facility in Georgetown, Ky.

True to the future product mission set forth by Toyota Motor
Corporation President Akio Toyoda, the new Avalon's more stylish,
bold, sporty exterior design and luxurious interior styling are
matched by an enhanced dynamic package, a combination that foreshadows
the more compelling and passionate nature of future Toyota products.
