Avoiding EV vs maximising EV

what is that in dog years?

 

I balance out my EV

If i were driving around the neighborhood, parking lot, or a 25 mph school zone, I try EV it all the way until the battery is down to 2 bars

If im driving on main roads I only use my EV to get up to 7 mph and then use the ICE to accelerate to 5 mph higher then the posted speed limit then coast, glide and regen when im approaching to a traffic light or stop sign.

Now since your in UK and your mpgs are diffrent then ours, UK mpg is 57.7- 61.8 and US MPG 48.1-51.0 MPG, granted that i'm not using LRR tires, our gas contains 10% ethanol and my commute is mostly highways at 65-70 mph.

 

What is your tire (oops, I meant tyre) pressure.

 

My first thought: stay clear of both extremes, use EV when you've got good charge level, try to avoid EV with the HSD bar almost at the median (eats the charge fast), and purposely activate the engine, switch to pulse-and-glide, when battery level drops significantly.

 

Mental note (dont drain battery to 2 bars) and btw whats lunar and glide???

 

^ I'm gonna blame lunar-and-glide on iphone spellcheck. Fixed, thanks.

 

Insufficient information:

• Post a Google Map, Google Earth, or equivalent that maps your usual route
  • Include lunch if typically eaten out
• Include the normal commute times: start and durations
• It is OK to have the nearest corner to work and home to preserve privacy

Then we can discuss efficient driving strategies.

i give up, what is 70mpg in u.s.?

 

70/1.2 = 58 mpg US

 

thanks, that's excellent! you should be very happy. of course, i'm very happy, but always trying for more. that's half the fun!

 

Good numbers.

Yes. Few Prius drivers routinely get those numbers. My best averages are 54 mpg(US)/65 (UK). Further mpg improvement would require significant slowing on my express lane/interstate segments. It's not worth it to drive that slow at rush hour.

Very little without becoming a distraction to other drivers. The mpg you are getting is great for rational driving habits. Further gains in mpg will require slow accelerations and slow speeds.

 

If you can take a secondary highway, with lower speeds, you can achieve better mpg. Old but true adage:

Haste makes waste.

 

I can get 4.0 l/100km (58 US mpg) with my eyes closed. I just don't go oven 80 kph, and base my strategy around ICE efficiency. We know that the optimal efficiency of the ICE is roughly the ECO area of the HSI above the midpoint.

A) If the load is such that it will naturally keep the ICE operating with optimal efficiency then definitely use the ICE.

B) If the load is such that it will keep the ICE operating below optimal efficiency then either P&G, with the pulse putting the ICE in optimal efficiency mode, or if the load is really small (slight downhill) try to maintain speed with the electric motor.

C) When I know I'm about to be forced to use the ICE under scenario A for at least 2-3 minutes, then I can be less shy about using the battery. For example, if you have about a mile of slow driving before getting on a highway that you will drive under scenario A initially, then riding that mile with the electric motor is OK since you'll recharge with the ICE running at optimum efficiency.

 

I don't see how going into PWR can have a positive effect on mpg. If science says the ICE optimal efficiency is in the upper half of ECO then every time you operate it outside that area you get less efficient conversion of gas energy to kinetic energy, ie, less kinetic energy put into the car per unit of gas.

Incidentally, efficiency is also why it's better to glide on small downhills rather than allow regen, because regen only captures 30% of the kinetic energy it removes from the car.
