TORRANCE, Calif. — Toyota’s all-new redesigned and re-engineered 2013 Avalon sedan will come in a V6 gasoline version and a hybrid version, featuring Toyota’s Hybrid Synergy Drive. The hybrid is estimated to achieve an EPA fuel efficiency rating of 40 mpg combined, matching the fuel efficiency of the leading luxury hybrid sedan now on the market, the Lincoln MKZ Hybrid.

The gasoline model of the 2013 Toyota Avalon runs on a 3.5-liter DOHC V6 engine coupled with a six-speed automatic transaxle, which has been engineered to be more responsive and efficient. The V6 will produce 268 horsepower and 248 lbs. ft. of torque, which will propel the sedan from 0-60 mph in under seven seconds.

The powertrain programming has been updated to offer three modes: Eco, Normal and Sport. The Eco mode prioritizes fuel efficiency by reducing powertrain application at lower speeds and reducing energy consumed by the air-conditioning system. The Sport mode provides increased acceleration responses through altered engine control unit programming, and offers a more direct and responsive EPS programming to improve steering feel.

The V6-powered Avalon is estimated to get an EPA-rated 25 mpg combined (21 city / 31 hwy).

Toyota is also introducing a hybrid version of the 2013 Avalon, which incorporates the automaker’s latest advances in its Hybrid Synergy Drive technology. 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.

The hybrid sedan’s power control unit in the engine compartment houses an inverter, a DC-DC convertor, a step-up converter and the hybrid-drive ECU. The power control unit maintains an efficient temperature through liquid cooling.

The Avalon hybrid puts out a total of 200 horsepower and offers its own three driving modes: EV, Eco and Sport. The Avalon hybrid will get an EPA-rated 40 mpg in the city, 39 mpg highway, and 40 mpg combined.

The EV mode will allow the Avalon hybrid to operator solely on electric propulsion. It can be engaged for up to one mile at speeds up to 25 mph. The Eco mode engages the gas motor but reduces throttle responses and HVAC output to improve overall efficiency. Sport mode alters the engine’s throttle response and enhances 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 quiet and efficient airflow, helping reduce interior noise and elevating refinement. The hybrid vehicle transaxle also incorporates a flywheel-damper design that helps reduce noise and vibration during engine engagement.

The new 2013 Avalon is the product of a North American-focused design and engineering effort. The new sedan's exterior and interior design was conceived by a team at the Calty Design Research Inc. facilities in Southern California and Michigan.

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