What is B Gear in Toyota Prius?

Toyota Prius is a popular hybrid car, and one of its features is the ability to shift its transmission into a “B Gear”. This feature helps maximize the car’s efficiency when driving in certain conditions, such as going up and down hills, improving fuel economy.

What Does B Gear Do on a Toyota Prius?

B Gear on a Toyota Prius is similar to a lower gear in a traditional gasoline-powered car. It is a gear that can be activated when driving downhill or when slowing down to help reduce the speed of the car without using the brakes. This helps to conserve energy for the car and helps it maintain a steady speed without needing to use additional fuel.

In addition to this, B Gear on a Prius is also used when towing or when driving at higher altitudes or grades. By engaging this gear, the car can optimize its power and speed, while also conserving fuel.

Benefits of Using B Gear on a Toyota Prius

There are several advantages to utilizing B Gear on a Toyota Prius:

  • Improves Fuel Economy – By using B Gear, the Prius can optimize its fuel economy to get the most out of every gallon. This helps save money on fuel.
  • Smoother Driving – B Gear helps reduce the risk of sudden acceleration or deceleration when driving, making the car easier to handle and more comfortable to drive.
  • Reduces Wear and Tear – B Gear helps reduce the amount of strain that the car’s brakes are subjected to, which can help extend the life of the brakes.

How to Use B Gear on a Toyota Prius

Using B Gear on a Toyota Prius is relatively simple. All you have to do is press the “ECO” button on the gearshift, which will shift the car into B Mode. From there, the driver can shift the gearshift through its range to select the desired gear.

To return the car to normal, the driver must push the “ECO” button again, and the car will return to its normal transmission mode.


Using B Gear on a Toyota Prius can provide a variety of benefits, from improving fuel economy to reducing wear and tear on the car. It is an easy-to-use feature that will help any driver get the most out of their Prius.
