Braking Performance Comparison of a Sample of Light Trucks and Cars

A Supplemental Notice of Proposed Rulemaking (SNPRM, Notice 4) for FMVSS 135 has recently been issued proposing a new braking regulation for passenger cars. Due to interest in light truck braking performance as it relates to that of passenger cars, a sample of 13 light trucks was tested to the FMVSS 135 Notice 4 procedure for purposes of comparison with the performance of a sample of 19 passenger cars tested to the same procedure. The brake force balance and braking efficiency of the light trucks were also measured and compared to the same parameters of the set of 19 cars.
