2013 Toyota Avalon Confirms Hybrid

Last updated 5 years ago

When we reported the unveiling of the 2013 Toyota Avalon in April (Check it out at, Toyota had not revealed powertrain details for it, leading many to speculate the original 268 hp 3.5 liter V-6 engine would carry over. There were also rumblings of the possibility of a Hybrid engine being in the works.

Well ladies and gentlemen; we can now report that Toyota has confirmed a hybrid version of the 2013 Avalon is scheduled for production, coming in the form of a 154-hp, 153-lb-ft 2.5-liter Atkinson Cycle I-4 engine, capable of making the 2013 Avalon able to reach 140 hp and 200 lb-ft of torque combined.

The 2013 Toyota Avalon Hybrid’s fuel economy is EPA rated to reach 39/40 mpg city/highway and 40 mpg combined. The regular 3.5-liter V-6 engine gets 21/31 mpg city/highway and 25 mpg combined rating.

The engine will be powered by two electric motor-generators. One of the electric motor generators will start the gas engine and charge the batteries and the other functions as a traction motor and a regenerative braking unit. There is also a 244.8-volt nickel-metal hydride battery pack behind the rear seats. The combined output of the gas engine and electric motor has been rated at 200 hp.

The 2013 Toyota Avalon’s hybrid system will offer three hybrid modes: EV, ECO and Sport.

EV mode allows the vehicle to run exclusively on electric power for up to one mile at 25 mph or less under certain conditions. ECO mode improves the Avalon’s efficiency by reducing the gas engine’s throttle response and HVAC output. Finally, Sport mode enhances the Avalon’s throttle response and steering feel.

Those interested in buying a 2013 Toyota Avalon will have the choice between a 3.5-liter V-6 and the hybrid drivetrains when the car goes on sale later this year.
