Sierra LSV AX3
By The Smith Family, reviewed by Brad · Independent, no paid placement · Last verified Nov 10, 2026
Sierra's six-seater with a rear-facing third row: the same 48V 125Ah LiFePO4 pack and 5 kW AC motor as every Sierra, 25 mph, four-wheel hydraulic discs, and "MCO's & VIN's available" from an NHTSA-registered LSV maker. The catch: at 1,334 lb it is the heaviest Sierra on the same single 125Ah pack, and Sierra publishes no MSRP. Street-legal: yes (LSV certified). Dealer price range: $15,090–$15,995 (read Nov 5, 2026).

◆ Range reality check
Computed from the ≈6 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. Real-world range varies with load, terrain, speed, and battery age.

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.
