"E" blocks = how much distance?

at what speed?

 

My 2017 Prius manual says 1 E is 30 Wh and up to 5 Es per bar. I think each bar is a minute. You need to know what the EV only consumption rate is for your car to calculate the distance/speed data you desire.

I am not in my car right now but I thought the screen displaying the E had a legend telling you how much energy one represents. The Prius c may be different than my Gen 4 Prius.

 

This is a largely academic question, as it very much depends on the grade of the road you're driving on. I've gone 5 miles without the ICE on a long gradual downgrade.

Another way to answer your question is that if you use only regen to stop from 60, you'll have enough power to accelerate back to about 40. Or about 50% efficient.

It's impossible to know what distance that would be because it's impossible to predict your acceleration rate, climb or descent rate, speed, wind, water on the road, accessory load, cargo load, and other variables.

However, if you know your average distance per kWh, you can calculate it based on the number of "E"s. At 30 Wh per "E," 33.3 of them would be one kWh. So, if you average, for example, 4 miles per kWh, one "E" would get you an average of about 0.12 miles. At an average of 4 miles per kWh. At 3 per kWh, it would be about 0.09 miles. But since, braking is generally followed by acceleration, what we regenerate is worth a lot less than 3 miles per kWh in forward propulsion.
