The Ferrari 328 GTB and GTS (Type F106) was the successor to the Ferrari 308 GTB and GTS. While mechanically still based on the 308 GTB and GTS respectively, small modifications were made to the body style and engine, most notably an increase in engine displacement to 3.2 L (3185 cc) for increased power and torque output. 7,400 Ferrari 328s were produced by the time the model was replaced by the new 348 in 1989, bringing the total for the 308/328 generation to nearly 20,000. The 328 is considered by some Ferrari enthusiasts to be one of the most reliable Ferraris, unlike some models, most engine maintenance can be performed without lowering the engine from the vehicle.〔(【引用サイトリンク】title=An '80s Ferrari Icon )〕 The GTB referred to the Gran Turismo Berlinetta (coupé) body while the GTS was a Gran Turismo Spider (targa top). In 1985, the 328 retailed from $58,400-$62,500 ($126,400-$135,300 in 2013 dollars) in the United States. The 328 GTS model, together with the fixed roof 328 GTB, were the final developments of the normally aspirated transverse V8 engine 2-seat series. The 328 figures in the model title referred to the total cubic capacity of the engine, 3.2 litres, and 8 for the number of cylinders. The new model was introduced at the 1985 Frankfurt Salon alongside the Mondial 3.2 series. ==Overview== Essentially the new model was a revised and updated version of the 308 GTS, which had survived for eight years without any radical change to the overall shape, albeit with various changes to the 3-litre engine. The 328 model presented a softening of the wedge profile of its predecessor, with a redesigned nose that had a more rounded shape, which was complemented by similar treatment to the tail valance panel. The revised nose and tail sections featured body colour bumpers integral with the valance panels, which reflected the work done concurrently to present the Mondial 3.2 models, with which they also shared a similar radiator grille and front light assembly layout. 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 complemented the external updating details. Optional equipment available was air conditioning, metallic paint, Pirelli P7 tyres, a leather dashboard, leather headlining to the removable roof panel plus rear window surround, and a rear aerofoil (standard on Japanese market models). In the middle of 1988 ABS brakes were made available as an option, which necessitated a redesign of the suspension geometry to provide negative offset. This in turn meant that the road wheel design was changed to accommodate this feature. The original flat spoke "star" wheels became a convex design, in the style as fitted to the 3.2 Mondial models, whether ABS was fitted or not. The main European market 328 GTS models had a tubular chassis with a factory type reference F 106 MS 100. Disc brakes, with independent suspension via wishbones, coil springs, and hydraulic shock absorbers, were provided all round, with front and rear anti roll bars. There were various world market models, each having slight differences, with right and left hand drive available. The V8 engine was essentially of the same design as that used in the 308 Quattrovalvole model, with an increase in capacity to 3185 cc, with a bore and stroke of x , 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 at 7000 rpm. As with the preceding 308 models the engine was mounted in unit with the all synchromesh five-speed manual transmission assembly, which was below, and to the rear of the engine's sump. A minor problem was the oil hose from the lower part of the engine to the oil cooler. This was too short since a running engine was moving separate from the oil cooler. This hose was almost solid being under pressure and in time the oil cooler would crack. This was solved by connecting the oil hoses for the oil cooler to and from the engine "up side down" to make the lower hose, now connecting to the top of the oil cooler, longer and movable. The 328 GTS continued in production for four years, until replaced by the 348 ts model in the autumn of 1989, during which time 6068 examples were produced in the chassis number range of 59301 to 83136, the GTS production outnumbering the GTB (1344 produced) version almost five to one. 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 number sequence. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrari 328」の詳細全文を読む スポンサード リンク
