The GTS stands for Gran Touring Spyder and was offered as a targa-top model.

Power came from a larger 3.2-liter V8 engine bolted to a 5-speed manual gearbox mounted right under it next to the engine’s oil sump.

The 328 uses a 3.2-litre development of the 3.0 quattrovalvole (four valves per cylinder) V8 from the Ferrari 308.

The Ferrari 328 GTS, a mid-engine V8, two seat sports car produced by Italian automotive manufacturer Ferrari. It was the successor to the Ferrari 308 GTB and GTS. While mechanically still based on the 308, small modifications were made to the body style and engine, most notably an increase in engine displacement to 3.2 L for increased power and torque output. The 328 is still considered by some enthusiasts to be one of the most reliable and functional Ferraris; unlike other models, much of its maintenance can be performed without lowering the engine from the vehicle. In 1989, the 328 was succeeded by the 348.

The GTS was a Gran Turismo Spider (targa top). In 1985, the 328 retailed from $58,400-$62,500 ($130,388 – $139,542 in 2016 dollars) in the United States.

The “328” numbers in the model title referred to the total cubic capacity of the engine, 3.2 liters, and 8 for the number of cylinders. The new model was introduced at the 1985 Frankfurt Salon alongside the Mondial 3.2 series.

The 328 was the final evolution of the transversely mid-mounted, conventionally aspirated 90 degree V8 Dino engine. The transversely mounted engine is a popular way to save space on the rear-mid, rear wheel drive layout.

The 328 has been described as one of the most usable classic Ferraris because of its durable road record, history of appreciating value, and classical aesthetics.

The interior trim also received a thorough overhaul, with new designs for the seat panel upholstery and stitching along with revised door panels and pulls. Cockpit switches were completely updated and modernized. The new back lit orange on black dashboard gauges were borrowed from Ferrari’s 1984 GTO supercar. The main instrument panel, seen through the anatomical Momo (Morreti-Monza) steering wheel, presented the driver with information from the large tachometer and speedometer.

Optional equipment available is air conditioning, a leather dashboard, leather headlining to the removable roof panel plus rear window surround, metallic paint, Pirelli P7 tires, and a rear aero foil (standard on some market models).

The last production year for the 328 GTB/GTS was September 1988 to Sept/Oct 1989 (model year 1989). 1338 total vehicles were manufactured that year. With Enzo Ferrari’s death in August 1988, many of these last cars were purchased either as a tribute or with speculation in mind. Decades later, it is still not unheard of to occasionally find a 328 for sale from the last production year that was never registered for road use.

The front and rear independent suspension is based on the traditional unequal length double wishbone design. It included coil springs and hydraulic telescopic Koni shock absorbers. It featured front and rear anti roll bars. The brakes were large, vented discs with twin piston calipers actuated, as on the 308, by a hydraulic system offering security through redundancy. The anti-lock braking system was a late model addition with updated suspension geometry to further reduce squat and dive. The steering is unassisted rack and pinion slightly quicker than its predecessor at 3.25 turns, lock to lock.

But for the 328 the biggest change was made under the hood. The displacement of the V8 engine was increased to 3.2 liter, a larger, redesigned oil cooler system was added, and a Marelli Microplex single module ignition system was adopted.

The 3185cc V8 engine delivered a total of 270bhp at 7000rpm. As with the preceding 308 models the engine was mounted in unit with all synchromesh five speed transmission assembly, which was below, and to the rear of the engine’s sump.

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.
