Toyota's hybrid bug has finally bit the Avalon. The 2013 Toyota Avalon will be offered with a V6 gasoline engine or a hybrid model.

The hybrid version of the flagship sedan will use a 2.5-liter, four-cylinder engine and a pair of electric motors to produce 200 hp and get an EPA-estimated 40 city mpg / 39 highway mpg. The Avalon Hybrid will have three modes, EV, Eco and Sport. EV model will provide electric-only power for up to one mile at speeds up to 25 mph. Eco uses the gasoline engine, but reduces throttle response and the climate control system output to improve fuel efficiency. Sport mode improves throttle response and enhancing steering feel.

When equipped with the 268 hp, 3.5-liter V6, the 2013 Toyota Avalon will be more powerful and have better fuel economy than the 2012 Toyota Avalon. The gasoline engine also has three modes: Eco, Normal and Sport. Eco reduces power at lower speeds and the energy used by the air conditioning to improve fuel efficiency. Sport mode increases throttle response and changes the computer programming to provide more responsive steering. It will get an EPA-estimated 21 city mpg / 31 highway mpg.
