The cab produced at Umeå from hot-dip galvanized, high tensile steel allowed for greater strength at thinner panels and box sections while reducing overall weight. The new FH cab was a logical progression from, for its days spacious but boxy F series cab to more aerodynamically efficient, with much-improved ergonomics and much better seating unit while reducing the overall weight of the cab by almost 30%. The cabin was extensively tested in a wind tunnel to confirm shape aerodynamics properties to reduce air-drag thus improving fuel efficiency. The cab featured a more sharply raked windscreen while wedge-shaped sides rounded into the front panel at much wider radius corners and the rear vision mirrors were also streamlined. The cabin was subject to the toughest cab impact test where procedure involved placing a 15-tonne static weight on the roof and one-tonne pendulum striking at the cab rear wall and at the windscreen pillars, at the end of which the cab doors must be able to be opened. In 1995 Volvo FH series became first heavy-duty truck to be fitted with an SRS airbag to further improve passive safety.
