Diesel is slightly more power dense than gasoline, but usually more expensive to purchase. The capital costs are much higher, as are the maintenance costs. You don't buy a diesel to save money, you buy it for torque. Electric is so much cheaper that the only reason EVs haven't abruptly taken >50% of the market is because capital cost remains fairly high and charging availability is still low compared to liquid fuels. Normally, efficiency improvements significantly smaller than the EV advantage result in dramatic movements in buying patterns.
