Wayland's conversions are unique. They are extremes and they use high end components that are made available by sponsors.
The battery pack has very high energy density compared to the prismatic cells that we have access to. For the same weight, a prismatic pack would yield ~45kWh, compared to what…~72kWh with the Kokams?
The Weight Reduction
s also are potentially better for Wayland with a more powerful motor that doesn't require the transaxle to be retained, whereas it's likely the everyday converter would retain the transaxle (and its weight, say 70lbs?). Although as someone said, you could use those small PMDC motors with high power density and maybe it would be a wash in weight savings.
I'm making a generality of course, but compared with the Insight, other cars can be overladen with less safety issues. Remember that the Insight is composed of a lot of aluminum in critical areas. Aluminum doesn't bend as much as steel when overstressed. Again the payload is 400lbs. That means after two 160lb people get in, that leaves 80lbs of payload room. Even with ~330lbs of weight savings, you would probably be better off adding some extra support, unless you don't go over a 400lb battery pack.
I'm just saying that it would be great to have access to some of the insight (forgive the pun) that Wayland and team accumulate during the build. It would be a boon to converters.
Can't wait to hear an update from Wayland.
