While any physics model can generate numerical predictions, the critical question is whether these predictions align with real-world observations. We collected over 34 owner-reported efficiency figures from a UK electric vehicle community thread on Reddit, matched them to our catalogue vehicles, and compared the model’s predictions with these reported values.
The model operates at 40 mph and 15 degrees Celsius with an 80 kg driver payload, under dry conditions and without preheating. These parameters represent mixed summer driving, which most owners reference when reporting ‘good weather’ efficiency. No state-of-health adjustment is applied, as efficiency (mi/kWh) is determined by the powertrain and driving conditions rather than remaining battery capacity.
When the model prediction falls within the owner-reported range, the corresponding cell is marked green. If it falls outside this range, the magnitude and direction of the discrepancy are indicated. No model parameters have been adjusted to fit these data points. The physics model was constructed using manufacturer specifications and first principles prior to the collection of any owner data.
