2019–2021 Toyota Avalon Hybrid XLE
EPA Rating: 43 mpg city / 44 mpg highway / 44 mpg combined
The Avalon was all new for the 2019 model year — built on a completely new platform, it features new looks inside and out as well as plenty of new convenience and safety features. Toyota equips the Avalon Hybrid with its next-generation hybrid powertrain, which combines a 2.5-liter Dynamic Force 4-cylinder engine with two electric motor/generators for a total system output of 215 horsepower. One electric motor/generator acts as the engine starter and charges the battery, while the second electric motor/generator drives the front wheels and captures energy through regeneration during braking.
