Methodology to Decide Overall Drive Performance Index of Passenger Vehicles 2022-28-0100

Fun to drive, pick-up of vehicle, high acceleration feeling of vehicle, time to reach max velocities are some parameters prevailing in the passenger vehicle market. In addition to focusing on information about fuel economy declared by manufacturer, the customer also has drivability related criteria in his mind. Although drivability is subjective, it can be judged by using various parameters like maximum speed, pick-up feeling, overtaking acceleration, time to reach 0 – 100 km/h or 0 – 60 km/h, etc. While comparing two vehicles of the same segment, one vehicle may perform better on some of the parameters while losses on others. To decide overall drive performance of a vehicle based on various measured performance related parameters, a methodology is defined. This will help to understand the overall performance of a vehicle holistically and to compare its performance with other vehicles in a better way. This paper describes a methodology to get a single number representing the overall drive performance. Suitable weightages are given to various drive related parameters according to the on-road driving scenario and statistically a formula is derived. The single number given by this formula is named as performance index. Higher the performance index, higher the actual performance of vehicle.
