The Ferrari 400i, produced from 1979 to 1985, represented a significant evolution in the Italian marque's grand touring offerings. Replacing the 400 GT, the 400i embodied a move towards a more modern and luxurious aesthetic, while maintaining the core principles of Ferrari's performance-oriented DNA. The 400i featured a sleek and aerodynamic Pininfarina-designed body, characterized by sharp lines, a sloping hood, and a low-slung profile. The interior, a haven of Italian craftsmanship, boasted sumptuous leather upholstery, plush carpeting, and a driver-focused cockpit. However, the 400i's appeal extended far beyond its stylish exterior. Under the hood resided a potent 4.8-liter V12 engine, capable of delivering a smooth and exhilarating 340 horsepower. This power plant, coupled with a 5-speed manual transmission, propelled the 400i to a top speed exceeding 155 mph, solidifying its position as a performance-oriented luxury car.

It offered a compelling blend of luxury, performance, and technological innovation, making it a highly desirable car for discerning enthusiasts. Though production ceased in 1985, the Ferrari 400i continues to hold its own in the realm of classic automobiles, appreciated for its timeless elegance, potent engine, and enduring legacy.
