You'd still need the battery, that was my point there. And a big one too.
In effect you need a very big battery and still have way less range than the cheapest Leaf you could buy.
And you'd weigh down the car considerably. Ordinary cars would already be beyond their load capacity from that battery alone. There would not be much space left to load anyting either.
You'd have a chance if you replace the heavy engine and adjacent systems with a motor and controller, and of course you'd get a better range.

You choose diesel as a way of cutting cost, but the rest of the setup will annihilate any gain you could get there. With safety and practicality already gone, cost is no longer relevant either.
This goes nowhere.
