◆ Range reality check
Computed from the ≈5.04 kWh pack (system voltage × amp-hours) at a standard 0.125 kWh per mile — the same efficiency on every model, so ranges compare apples-to-apples. Manufacturer “up to” figures are usually measured at 19 mph on the largest optional pack, which is why the claim runs high.

Our figures, from verified specs + the cart's sourced price — lower cost-per-seat and cost-per-mile is better; higher power-to-weight means more pep and hill-climb. Range uses the normalized estimate. Cost per kWh is what the price actually buys you in battery — the single figure that separates a cheap cart from an under-batteried one, and almost nobody publishes it. Pack energy is the maker's published kWh where they give one, otherwise volts × amp-hours.
