The “B” creates something called “engine braking,” which mimics the behavior of a traditional transmission: It fakes a downshift to slow the Prius if it’s descending a hill. Why? To keep the brakes from being overloaded if you’re on a long, steep grade.
How do you use the B on the Prius?
Just as you might downshift into 2nd gear when going down a long, steep hill to prevent brake damage, you can “downshift” into “B” mode on a Prius. “Shifting” is all electronic, so the system won’t let you shift in a harmful way.
What does B mean on Toyota automatic?
Whereas, the B stands for Brake or engine braking. When you are doing downhill, it is advised to shift the car in B mode. It engages the engine braking, and your car won’t free-fall down the slopes. It increases the engine drag. … B is mostly written in Toyota cars.
What is B on the Prndl?
A normal Automatic is PRNDL, some one at Toyota was too honest to call theirs L because there are no Lower gears, just engine braking, so they called it B. If you went down a long steep hill in a Prius, the HV Battery would fill part way down and you would have no regenerative brakes, just friction brakes.
Should I drive my Prius in eco mode?
ECO mode is better suited for stop&go city traffic, where frequent stops and accelerations could lower FE if the driver accelerates aggressively (due to personal style, or traffic flow) several times in a row in short trips.
What does B mean on Prius?
The “B” creates something called “engine braking,” which mimics the behavior of a traditional transmission: It fakes a downshift to slow the Prius if it’s descending a hill.
At what speed does the Prius switch to gas?

Can you shift from D to B while driving?
Yes, it is OK to shift between D and B or B and D while driving. All you are changing is the computer program for regeneration; more battery recharge in B but no cruise control function there.
Can you shift from D to S while driving?
You can definitely switch from D to S while driving, just don’t do it while pedal to the floor. Even that is probably safe as the computers won’t let it hurt the car, so it will only shift when its safe to do so regardless of what you ask it to do via the lever.
Can you shift from D to L while driving?
Yes, but doing so at high speed will be jarring to you and your transmission.

Which Prius has the best mpg?
The new Toyota Prius Prime plug-in hybrid has the best gas mileage, getting up to 55 city mpg and 53 highways mpg, as well as up to 133 MPGe. In addition to this new plug-in hybrid, Toyota offers an extensive lineup of fuel-efficient cars and SUVs that are fit for any occasion.
What is D and S in automatic car?
A traditional automatic gearstick has a PRNDS layout—P for park, R for reverse, N for neutral, D for drive, and S for sport mode. Certain gearsticks have an L (low) setting, which keeps vehicle speed low and engine speed high, for more pulling power.
What is EV mode?
EV (short for Electric Vehicle) mode is only available in hybrid vehicles and is much more particular in its uses than other driving modes. If a vehicle is running in EV mode, the vehicle is only pulling power from its battery.
Does Eco Mode hurt engine?
It does not harm your engine or gearbox. However, you cannot reap any benefits by using this setting while driving aggressively (hard acceleration and sudden braking). Adopt a gentler driving style instead.
What is the best mode to drive a Prius in?
In Eco mode, the car is most fuel-efficient, but accelerates more slowly than most four-cylinder midsize cars. In power mode, it is least efficient, but quicker away from a stoplight.
Why is my Prius only getting 40 mpg?
The more coasting you can do, the higher your MPGs. The longer you drive, the higher your MPG average will be. Short trips will kill it. If you’re constantly quickly accelerating and quickly slowing down, your MPGs will be low.
