Built between February and October 1969, the 365 GTS had the same refined mechanicals as the 365 GT 2+2 and the 365 GTC. Fed by three Weber carburettors, the 60° V12 was remarkably torquey and had huge reserves of power. The rear-mounted five-speed gearbox contributed in distributing the weight evenly over the front and rear axles. Air conditioning and wire wheels were available as options. Just 20 365 GTSs were built.
The 365 GTS “spider” replaced the 330 GTS model in late 1968, although the first car wasn’t built until 1969. Visually it was virtually identical to its predecessor, apart from the omission of the exhaust air outlets on the front wing sides, which were replaced by a trapezoidal black plastic louvre panel close to each trailing corner of the bonnet. The only other external difference was that the 330 GTS model had a small “330″ script badge on the boot lid below the Ferrari script badge, whereas the 365 GTS model had only the Ferrari script badge.
Internally there were small changes to the dashboard and centre console, the most obvious being the addition of two circular directional demister outlets in the centre of the dash top. Like the 330 GTS models, the bodies were built at the Pininfarina works in Turin, then delivered fully trimmed to Ferrari for fitment of the mechanical components.
The folding roof of the 365 GTS was retained by a pair of over-centre clips on the top screen rail when in the erected position, whilst a clip-on protective vinyl cover fitted over it when stowed in a recess behind the seats, otherwise it was identical to the sister 365 GTC model. The bodies were mounted on a 2400mm wheelbase chassis with factory reference numbers 592C, and all were left hand drive and numbered in the odd chassis number road car sequence, in the range 12163 to 12493. The layout was virtually identical to that of the models replaced, as the only mechanical change that had occurred was in the size of the engine. The standard road wheels were the ten-hole alloy design, as fitted to their predecessor, whilst similarly Borrani wire wheels were available as an option.
The engine was an enlarged version of that fitted to the 330 GTS, and identical to that used in the 365 GT 2+2 models already in production when the 365 GTS was announced. It was a single overhead camshaft per bank V12 unit, with factory type reference 245/C, of 4390cc capacity, with a bore and stroke of 81mm x 71mm. It was fitted with a bank of either three twin-choke Weber 40 DFI/5 or 40 DFI/7 carburettors, with a twin coil and rear-of-engine mounted twin distributor ignition system, to produce a claimed 320hp. The 365 GTS and sister 365 GTC would be the last Ferrari models to be announced with a single overhead camshaft per bank engine, as although the 365 GT 2+2 model continued in production after them, it had gone into production before them. The 365 GTS shared the same five-speed transaxle transmission, and independent rear suspension layout as the 330 GTS model, and as with all Ferrari cars since the beginning of the sixties, four-wheel disc brakes were fitted, with a cable-operated handbrake to the rear wheels. The 365 GTS had a very short production run, and was deleted from the range during 1969, by which time 20 examples had been built, making it one of the rarer models of the period.
