Touring was contracted to revise the basic GTV shape into something more suitable, and eventually produced then new car as well. The 350GT took the best of the GTV, which was basically the engine and general shape, and changed just about everything else. The bodies were produced using Touring's famous, patented Superleggera ('super-light') construction consisting of a framework of small tubes on which the aluminum panels were attached.
The chassis went from being a tubular frame to a floor of square and rectangular steel tubing, also by Neri and Bonacini. The wheelbase was stretched by 3.9 inches althought the overall length of the car would not change.
Early 350GTs (only about 9 of them in total) were fitted with a third seat in the rear to give 2+1 seating, although this was later replaced by an upholstered shelf for storage. The earlier cars also had one piece front bumpers and red Lamborghini badges that would give way to the now familiar black and gold.
The retractible headlamps, an oddity on the GTV were replaced by more powerful oval Cibies now fixed in place. Other exterior changes included a softening of all the sharp edges especially in the tail section, and the addition of more window glass.
Engine revisions to Giotto's orginal GTV brought horsepower down to 270 at 6500rpm and peak torque of 239 lbft at 4000rpm. Other changes included moving the distributors to the front of the engine and the adoption of a single, very tall Lamborghini made oil filter. Plugs were now expensive platinum tipped to operate across a wider temperature range and resist fouling at low speed. This all made for a smoother, more pleasant, longer-lasting engine. This was mated to a German ZF transmission running power to the rear wheals through a British Salisbury differential.
The new car was introduced at the 1964 Geneva show in March to great reviews. Orders started to come in. Only thirteen cars were built that first year with estimates of $1000 being lost of each one, even at a $13,900 US sticker price.
Various modifications were made to the 350GT over its production life.Some of these were a revised grille, the addition of cowl air intakes, a second windshield wiper, a backup light, and leather replacing the polished aluminum on the dash. It will be interesting to document these in full as more cars are registered.
In total, Lamborghini produced 120 350GTs, the last four constructed in 1967.
