The entirely new Ferrari 308 made its debut at the Paris Salon in 1975 and marked a welcome return to Pininfarina styling, with rakish lines and curved haunches. After ten years of huge success, particularly in the United States, Ferrari had grown weary of the “Federalisation” of their lovingly designed motorcars in America, with mandatory ugly rubber bumpers ruining the Pininfarina-penned lines. With their Italian aesthetics under attack, Ferrari launched the new Ferrari 328 GTS with body coloured front and rear bumpers which adhered to US guidelines, and for the first time, the design remained unadulterated by bureaucracy.
Increasing both bore and stroke, the quattrovalvole engine’s capacity was raised to 3,186cc which, together with a higher compression ratio, revised pistons, and an improved Marelli engine management system, lifted maximum power to 270bhp. Top speed was raised to within a whisker of 160mph with the sprint to 100km/h covered in a fraction over 5.5 seconds.
Beneath the skin, the tubular steel chassis remained much as before, with all-round independent suspension by double wishbones, four-wheel servo-assisted disc brakes, and aluminium-alloy wheels, though the latter were increased in size. The interior too had come in for subtle revision and now featured improved instruments, switchgear, and heating. Production ended in 1989 and by then some 7,412 Ferrari 328 GTS and GTB variants had rolled out of Maranello.
