ARAI re­de­fines ground clear­ance

Commercial Vehicle - - NEWS -

The Au­to­mo­tive Re­search As­so­ci­a­tion of In­dia (ARAI) has re­vised its norms to mea­sure ground clear­ance of a ve­hi­cle. The mea­sure­ment for ground clear­ance will be with a ve­hi­cle loaded to its max­i­mum ca­pac­ity or the Gross Ve­hi­cle Weight (GVW). The mea­sure­ment un­til now was with the ve­hi­cle un­laden, or at the kerb weight level. An im­por­tant di­men­sion, ground clear­ance is of­ten re­ferred to to gauge the abil­ity of a ve­hi­cle to tackle ob­sta­cles or ne­go­ti­ate less than ideal sur­faces. In­dus­try ex­perts claim that the ground clear­ance of a ve­hi­cle of­ten re­duces by 10 to 20 per cent when loaded to the max­i­mum weight. Given the ten­dency to over­load in In­dia, there can be a fur­ther re­duc­tion in the ground clear­ance of a ve­hi­cle, which has a safety im­per­a­tive. Some man­u­fac­tur­ers are said to spec­ify the ground clear­ance of an un­laden ve­hi­cle de­spite the re­vi­sion in norms. They should start spec­i­fy­ing the ground clear­ance as per the new, GVW norm.
