I'm having trouble with the math.
40% battery
41% chassis
42% engine
123% !
or
25% battery
26% chassis
27% engine
78% total (rest of car ~ 22%)

- lallysingh 4y agoBattery: 40%. Leaves the remainder: 60%. Chassis is the most expensive component of that remainder (no engine in EVs). Let's pretend the battery and chassis are the only two parts: 40% + ((1-40%)*60%) = 40%+36% = 76% cost of original. 24% reduction.
- flavius29663 4y ago> reduce investments needed to build chassis - a vehicle's second most expensive component after the engine - by 40%, and To me this is pretty clear: the press reduces the cost of the chassis by 40%. It could be 10%, 80% of the total cost of the car, it doesn't say.
- notJim 4y ago> 123% ! Now you understand why EVs cost so much more than ICE vehicles!
