Engine
The changes of the powertrain of the 2017 Toyota Avalon are not going to happen, the model is going to keep to its old engine and is going to keep it for at least another year long.We are of course talking about a  3.5-liter V-6 engine that makes 268 horsepower and 248 pound-feet of torque. It is perhaps not a powerhouse but it is still an engine that brings us an appropriate output and is an adequate choice for the car. The gearbox choice is the  a six-speed,paddle-shift transmission which places the EPA ratings at 21 mpg city and 31 mpg highway.
