The 20/20 Challenge

I just got close to 400 miles on one charge. Not in a specially designed marathon, but in my daily commute over the course of 3 weeks.

I only did two main things:
Used zero heat or air conditioning.

Accelerated at 20 kW or less and braked at 20 kW or less. *When feasible.

So I'm calling this the "20/20 Challenge".

Challenge yourself to accelerate at 20 kW or less. This is not as difficult as it sounds. This is faster acceleration than an 18 wheel truck, and about the same acceleration as the smallest horsepower economy gas car. A bit more gentle than most, but I did it for 3 weeks in the SF Bay Area and never got honked at once.
* I say "whenever able". Exceptions are allowed. The freeway on-ramp is one place I had to break my own rule...if traffic was flowing at the speed limit. If I could look ahead and see the freeway was jammed, then no need to sprint down the on-ramp. I kept it under 20 kW in those cases. Once on the freeway keep it at 60 mph or less. You will see you will have no trouble keeping it under 20 kW at 60 mph or less. Hills are the exception. For me bridges are hills, and I had to exceed 20 kW for those brief instances going up bridge

Braking: I used L almost exclusively. Love one pedal mode. BRAKE at 20 kW or less. When able. Don't hit anyone! I found this even more of a challenge and you have to break the rule and "brake" to not hit others. But when you have a lot of room, try braking at 20 kW or less.

I'd say I kept acceleration under 20 kW 90% of the time.

I'd say I kept braking under 20 kW 75% of the time.

I kept speed under 60 mph 100% of the time. 55 or less 95% of the time.

Temperatures 48 to 72 degrees.
The end result:
28881

I am going to take this challenge, my commute is boring anyway. I do 80 miles round trip 5 days a week.... let's see what we can get . I can always go back to normal later.
Ok gang, I have done the 20/20 challenge all week, What a difference in my efficiency.... this is the way to commute! I only charged once all week, versus everyday before.
My 80% max charge top I have said 265 miles when I did charge up.... I am going to try it with "Sport" mode and see how it does by comparison.

Forgot my stats: begin each day with 30-40 temp end with 75 temp (No climate controls) Totally did 55 on the highway 80 miles a day... kept my regen to 20 or less, no braking (I had thought regen to the max was better.... but not so much. No brakes, just shited L or paddle stopped. If I keep driving like this for a couple weeks I will be at 350+ capacity with 80% top.
Yeah... I tried, too.
But then, about 150 miles into my "tank", I could not stand the slow moving cars an I zipped between them.
Screw the efficiency! :D

So far I saw 5.5 miles/kWh. That would give me over 300 miles on the full charge.

What kills my stats are stop and go. If I could just roll... it would be nearly 6 as speeds are about 45 mph and below.
I did a trip at 50 mph steady, round 60 miles, and the average was 5.2. But that was no stopping at all. Maybe once.

With average of about 4.5 miles to kWh I translate it to (using MI petrol price 3.0/gallon for premium at Costco and 0.15/kWh at home) 90 MPG.
Far better than, say GTI if I had one now, that would average 20 MPG.

If I do 5.5 m/kWh, it would be 110 MPG.
What for? No fun... why would I buy GTI if I do not drive it?

The car is to be driven.... zooommm, brrruuuum, burp, burp (those are DSG farts :D)
Well now you know what you can get.... so Drive away.... do the Beep Beep here comes the roadrunner.... LOL

I must admit, I probably like to relax more than most on my commute. I take personal time and do some thinking and meditating on my highway commute. On occassion though I love to open her up and put on some "Grove" music and just enjoy. My next electric (won't be commuting anymore) will be much more fun to drive....
Don't forget your sign!

That is Hilarious!!!
still laughing here
Are you saying Bolt is not fun to drive?

Although, I must admit - 500e was way more engaging and feisty.
Well it is fun, but the styling does not say fun/flashy.... a super aerodynamic sporty looking futuristic style is what I would like....
But it is cool to slam by the "so called" fast cars.... it is funny to watch the look on their face... LOL
The bolt is well designed, maybe not the prettiest but very handy (love mine)... but if I want to do some "sporty" type driving it just lacking in some details.
currently I just plain commute in it.... 80 mile highway driving (if I had self drive I would take a knap) so just cruzing and seeing how much I am saving not buying gas is really awesome!

In 8 years (when I get my second retirement) I want to buy an electric Truck and pull a trailer and travel the country and enjoy my last days here on the planet. My wife like this idea also.

So let's face it... different strokes for different folks. Electric is here to stay, unless the Hydrogen guys can get their act in gear like right now....
If chevy could make more comfortable seats, better wheels, shed some more pounds- this Bolt will be a money maker for sure.... I am not doing the 20/20 any longer just doing normal "EV" driving
this mornings charge status was 277 miles at 83%... now take that to the bank!
