The Lamborghini 400 GT is a grand tourer produced by Italian manufacturer Lamborghini. The original 400 GT, also known as the 400 GT or 400 GT Interim, was essentially a larger version of the 350 GT with a 3,929 cc V12 engine that produced 320 horsepower. (235 kW).
The increase in engine displacement to four liters gave origin to the designation 400 GT. The 400 GT 2+2 was the second generation of the 400 GT, and it incorporated two child-safe back seats and a longer wheelbase.
