Thus all the eight cylinder cars in the range shared fairly unified front and rear aspects, providing a homogeneous family image. The exhaust air louvres behind the retractable headlight pods on the 308 series disappeared, coupled with an increase in the size of the front lid radiator exhaust air louvre, which had been introduced on the 308 Quattrovalvole models, whilst a new style and position of exterior door catch was also provided.
The interior trim also had a thorough overhaul, with new designs for the seat panel upholstery and stitching, revised door panels and pulls, together with more modern switchgear, which complimented the external updating details. Optional equipment available was air conditioning, metallic paint, Pirelli P7 tyres, a leather dashboard, leather headlining plus rear window surround and a rear aerofoil (standard on Japanese market models).
The V8 engine was essentially of the same design as that used in the 308 Quattrovalvole model, with an increase in capacity to 3185cc, with a bore and stroke of 83mm x 73mm, and a type reference number F 105 CB 000.
The engine retained the Bosch K-Jetronic fuel injection system of its predecessor, but was fitted with a Marelli MED 806 A electronic ignition system, to produce a claimed power output of 270bhp at 7000rpm. As with the preceding 308 models the engine was mounted in unit with the all synchromesh five speed transmission assembly, which was below, and to the rear of the engine’s sump.
The 328 GTB continued in production for four years, until replaced by the 348 tb model in the Autumn of 1989, during which time 1344 examples were produced in the chassis number range of 58735 to 83017. The early part of the series was numbered in the Ferrari odd number road car chassis sequence, and later examples (post chassis number 75000) in the continuous numbe
