Congratulations Terry!!!
After years of development, and over 60,000 miles on his trusty (what began as a) 2012 Zero S, Terry finally won the Vetter Fuel Economy Challenge.

Great Job! Now, if only one of the electric motorcycle manufacturers would make a production model that can go 200 miles and charge up in an hour. :-)
Thanks for pushing the envelope!

I'm impressed Terry managed to cram 21kWh onto his bike...
While 172 miles at flat out speeds is just incredible.

Thanks Ben and Justin!
Here's a really good article from AutoBlogGreen that just came out tonight about it.

I think there will be another fairly in-depth article coming out soon about this particular accomplishment...
;) ;D 8) ::)

This will certainly come in handy during his next adventure. Hershner plans on kicking off National Drive Electric Week by becoming an official member of the Iron Butt community, riding 1,000 miles – from Chargepoint headquarters in Campbell, CA to the Mexican border and back – within a 24-period.
This would be a heck of an achievement, though I suspect it might get one or two petrol heads coming after him with torches and pitchforks... ;)

1000 miles in 24 hours is 12.5 hours of riding at 80 mph average, 14 hours at 70 mph. (Once you have enough charging power, total trip time is reduced by driving faster, even if less efficient)
1000 miles will probably use around 120 kWh. Terry has about 20 kWh onboard, so he needs to charge 100+ kWh in about 10 hours. At 22.5 kW (3 J1772), that's about 5 hours of charging. Barring everything goes smoothly, there's about 5-7 hours of "slack" to locate charging, slower speed travel to/from highways, traffic, etc.
1500 miles in 24 hours is another Iron Butt challenge. That's about 20 hours of riding even at 80 mph.. it'll need significantly faster charge rates, around 50 kW.
Model S85 for reference has about 200 miles of range at 80 mph (400+ Wh/mile), and can charge about 50% in 20 minutes (starting from low SOC) on 135 kW supercharger. It'll take about 95 minutes to drive and charge 100 miles, so it would barely be possible to drive 1500 miles in 24 hours with Model S in the best conditions.
I've done two 1000 mile trips in < 24 hours in my life, both by car. They were miserable, but perhaps with forced periodic stops they would have been more enjoyable (and safer).

My daughter used to ride her Suzuki GS500E between my home south of San Francisco and Ballard, Washington, north of Seattle, non-stop, several time a year when she used to live up there. It would take her 17 hours to travel the 950 miles, without stopping for anything but fuel. After about half that distance, I am cooked and need a break (and food and a nap). Some people are just able to sit longer and hang on longer and become less bored riding on a straight freeway than others. ???
