Running costs are going to drive this, the electrics eliminate a lot of maintenance costs with engine and transmission as well the regenerative brakes reduce the cost of changing brake packs. Reduction in cabin noise will be a huge seller as less drone and vibration helps with reduced fatigue.
1500nm just push and go, no gears to swing and regen braking recharging batteries every time you have to brake or control speed. Lots of things for cost conscious owners to think about…

Promo for this type of stuff seems wildly optimistic but vague on specifics. 500km of range, at what weight and terrain travelled.
How much $$ to charge these things to achieve max range, and how many battery packs is needed for a fleet of say ten trucks running between two main cities...
The cost of an engine rebuilt (approx $30-40k to inframe a Cummins) to convert to full electric, sounds too good to be true.
Brakes on most line haul units good for 1 million km or close to.
By then if the linings/pads haven't worn, S Cams/bushes or caliper pins/bushes will be flogged out due to vibration regardless of what is powering the truck, so thats a moot point.
Hydro gearbox retarders will work as good as any regenerative braking and make conventional brakes, and engine brakes redundant. So another moot point.
Brake fade is down to operator abuse or negligence (drive to conditions etc) not the tech used. Plus, brake fade isn't a regular thing, so thats clutching at straws to promote the supposed virtues of unproven tech in this application.
