ARAI mileage of UV & Sedan To present the data we tried a different approach. We took length as proxy for in-cabin space and stacked the models length-wise, distinct product segments became quite apparent in most of the cases. So we deduced a fuel (transmission) – length (band) matrix to present the data. If this assumption (length  in-cabin space) doesn’t hold true for any product then perhaps designers and engineers need to do a better job, think of the term clever engineer
