Blade Runner Redux - Tesla Cybertruck!

I think I'd want a 1952 Ford pickup grille bar for a bull bar/winch mount/driving lights mount.

Using the Bolt's EPA range of 238 miles at introduction, that's 12 miles--not 40.

A) I did not mishear, nor misunderstand about BOLT regen and adding 40-miles of range to the 60-kWh car.
B) Josh Tavel was not mistaken about the quanta.
C) What redpoint5 'guarantees' is of no interest to me.
D) I'm limiting my interest specifically to the Chevrolet BOLT regen capability.
E) The regen quanta presented in redpoint5's 'Quote' are not germane to the metric by which the Chevrolet BOLT regen quanta were derived.
F) repoint5's 70-mph-to-zero regen quanta are not germane with respect to the metrics by which GM ascertained their Chevrolet BOLT regen quanta.
G) In '14)' , I gave the specific citation from which the data I shared originated.
H) ' stop-and-go traffic' regen is not germane to the metric by which GM experienced the quanta they shared.
I suspect that an internet search would reveal the Federal Test Procedure all automakers employ when quantifying the EPA COMBINED MPG data supplied for a specific vehicle, printed on the vehicle's Munroney sticker.

I suspect you were poked over minutia to see if there would be a response. Test failed. Best to forget about it.

Gaining 20% range due to regen might be possible in the city test circuit, as it simulates 23 stops over a distance of 11 miles with an average speed of 21 MPH. If the same circuit was performed for the whole 250 mile battery range, that would be 523 stops... perhaps within the realm of belief in recapturing 11.2 kWh.

I'm not sure how the "combined" city/highway fuel economy is derived, but regen isn't going to add 40 miles of range in any scenario other than frequent stopping for the whole range of the battery.

If you were to take a standard hybrid and run the city cycle for a whole tank (which would be over 600 miles), and kept braking within regen limits, you could probably regen 11 kwh even if the battery only holds 1 at a time

According to fueleconomy.gov, the hybrid Camry gets 80% better fuel economy in city driving over the non-hybrid, which is one heck of an improvement. Somehow the highway fuel economy for the hybrid shows a 36% improvement.

I suppose I never knew how much the brakes were used on the highway test circuit. My assumption was not much, as I never touch the brakes on the highway.
