Any battery has a hard time storing an amount of energy that costs the same as itself during its lifetime. This is opposite to combustion engines, which can pump infinite amounts of dollars through their cylinders.
It's an insanely smart offering.

It's admittedly quite a bit more than the supercharger equivalent, but it's far from infinite.
removed my incorrect math re: dollars of fuel per engine
5,000 gallons per cylinder * 6 cylinders * $4 per gallon = $120,000
If you're putting 5,000 gallons through each of six cylinders at $4 per gallon, that works out to $120,000 of gas. Certainly outweighs the cost of the engine by a decent factor.
