At the 1976 Paris Auto Salon, Ferrari introduced the new 400 2+2, its replacement for the 365 GT4 2+2. Featuring distinctively angular styling by Pininfarina, the 400 continued to provide luxurious and spacious high-speed transportation for up to four passengers, powered by a front-mounted 4.8-liter V-12 engine with dual overhead camshafts. Precise handling was provided by power steering and a fully independent suspension with self-leveling actuators at the rear. Fuel injection was added in 1979-thereby creating the 400i, and by 1982, Ferrari had also revised the interior upholstery, switchgear, and bodywork to its final form. These post-update examples also received re-profiled camshafts, new headers, and reworked fuel management which together boosted peak performance up to 315 horsepower.
