They don't note from what speed and that seems like a basic physics violation to me on several points.
1 - the mass of the vehicle doesn't change significantly (they claim a 2k lb reduction in cab weight)
2- the limiting factor in truck accidents I have seen is tire grip not braking capacity
I would love for this to be real, I think it is an idea with great potential and a useful and disruptive use of hybrid technology...but this company sounds like pure vaporbsware to me. They claim typical rigs last 500k miles which seems seriously low to me
- LeifCarrotson 10y agoThey may be measuring engine braking. Many trucks use Jake brakes to slow down and save their regular brakes, especially on downhills. A regular engine brake only slows you down a little, and isn't nearly traction-limited. I imagine that an electric regenerative braking system could be friction-limited.
- avs733 10y agoyeah I assume it is something like that but I just don't see how that gets expressed in feet.
- beeboop 10y agoIf I had to guess, they're measuring 2x based on the cab alone - no trailer. I would guess the combination of 2k fewer pounds and better weight distribution would potentially do it? Not sure.
