The second 400 GT, commonly known as the 400 GT 2+2, had a different roofline, and small exterior changes compared to the 350 GT and 400 GT Interim. It was first presented at the 1966 Geneva Auto Show. The larger body shape allowed two seats to be installed in the rear, which the 350 GT didn’t have. The bodywork for the 400 GT was designed by Carrozzeria Touring. The 400 GT also had a Lamborghini designed gearbox, which greatly improved the drivetrain.
