In response to the competition from Maranello and their larger models, Lamborghini recognized the necessity for a four-seater and introduced the 400 GT 2+2 in 1966. This new model represented an evolution of the 350 GT, featuring an enlarged V12 engine with a displacement of 3,929cc. The 4.0-liter powerplant had initially debuted in 1965, finding its way into a few late 350 GTs, leading to their interim designation as the 400 GT. This milestone also marked Lamborghini’s introduction of its proprietary five-speed all-synchromesh manual transmission.
The 400 GT boasted a claimed maximum power of 320bhp, a substantial increase compared to the 350 GT’s 270bhp, allowing the 400 GT to achieve speeds exceeding 240 km/h. Impressively, despite its transition to a four-seater configuration, the 400 GT 2+2 managed to preserve the overall and highly acclaimed design elements of the 350 GT. The vehicle’s body was now constructed from steel, a departure from the aluminum construction of the 350 GT. Additionally, the 400 GT 2+2 incorporated twin headlights, a modification made to comply with the requirements of the United States market.
Throughout the production period spanning from 1966 to 1968, Lamborghini manufactured a total of 23 units of the interim 400 GT and 224 of the 400 GT 2+2. This rarity solidifies its status as one of the most exclusive Lamborghini models ever created.
