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. 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 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.
