The performance of tadpole electric vehicles (EVs) is significantly affected by various design and operational parameters, including vehicle weight, camber angle, tyre width, and kingpin inclination. In this study, a tadpole-structured electric vehicle was used for experimental testing. The effect of vehicle weight (up to 280 kg or 2800 N), camber angle, and tyre width on the vehicle’s range was tested by varying these parameters. Using the Design of Experiments (DOE), the Taguchi method, and Analysis of Variance (ANOVA), the parameters were optimized to improve vehicle performance, particularly its range. The experiments identified an optimized set of parameters—vehicle weight of 2400 N, camber angle of 1°, and tyre width of 90 mm—yielding a maximum range of 180 km per charge. This study provides a comprehensive set of recommendations for designers and manufacturers of small electric vehicles by systematically analysing the interactions between these parameters.
