The Worldwide Harmonized Light Vehicles Test Procedure (WLTP) is a standardized laboratory assessment intended to provide a repeatable and comparable range figure for all vehicles. The test incorporates speeds up to 131 km/h (81 mph), accounts for loaded vehicle weight, and uses aerodynamic drag values derived from coast-down measurements. However, the average speed during WLTP testing is approximately 29 mph, which typically results in range estimates that exceed those observed during sustained motorway driving or in cold weather. Both the WLTP and real-world figures are valid, but they address different aspects of vehicle performance.
The following table presents physics-based range estimates for each vehicle under three real-world driving scenarios: mild suburban (50 mph, 15°C), cold winter (55 mph, 2°C), and motorway cruise (70 mph, 10°C), alongside the official WLTP figure for comparison. The “Gap vs WLTP” column quantifies the difference under mild real-world conditions, enabling users to adjust expectations for a used vehicle with typical battery aging.
All data are generated in real time using the HonestRange physics model, which incorporates actual vehicle parameters such as mass, aerodynamic drag, battery chemistry, thermal management, and drivetrain efficiency. Each vehicle is modeled with typical age and mileage for a used example, defined as the year of introduction through 2026 and an average of 8,000 miles per year.
