Test Summary
Test Vehicle
Range Rover Sport Autobiography P525
Engine
V8 5.0L Supercharged
Test Date
October 25, 2025
Route
274 miles from Los Angeles to San Francisco, CA
Energy Contained in 1 Liter of Water
When one liter of water is separated into hydrogen and oxygen via electrolysis, it yields approximately 111g of Hydrogen. This translates to:
~13.3 MJ or ~3.7 kWh of chemical energy per liter of water.
The 360ES-PEM system turns this abundant resource into a range extender. The added oxygen improves combustion, while hydrogen's faster flame speed ensures a more complete burn.
Efficiency Results
Baseline
17.2 MPG
