Lamborghini 400 GT classic car for sale

History of the Lamborghini 400 GT

The Lamborghini 400 GT followed the groundbreaking 350 GT as the marque’s second series production model. Production ran from 1966 to 1968, directly at Lamborghini's Sant'Agata Bolognese factory. The 400 GT marked the brand's push into the world of high-performance grand tourers, offering both a 2-seater and a 2+2 version, presented to the public at the 1966 Geneva Motor Show. Lamborghini built the 400 GT on the foundations of the 350 GT, updating the V12 engine's displacement to 3,929 cm³ and retaining the elegant Superleggera lightweight chassis from Carrozzeria Touring. Striking design cues such as four round headlights distinguished it from its predecessor, while engineering updates ensured its competitiveness against period rivals including the Ferrari 330 GT and Maserati Sebring.

Model Evolution and Variants

Initially, 23 units of the original 400 GT (also called Interim) were built, featuring many similarities to the 350 GT but with increased engine capacity. Most recognisable, however, is the 400 GT 2+2—produced in 224 examples—which incorporated a revised roofline and more spacious interior thanks to a forward-placed windscreen and thinner roof pillars. This configuration allowed fitting of two rear seats, epitomising Lamborghini’s commitment to grand touring practicality. The model was, in turn, succeeded by the Islero in 1968.

Highlights and Unique Features

The 400 GT is defined by its lightweight Superleggera construction, a 5-speed manual gearbox developed by Gian Paolo Dallara, and a 3.9-litre V12 by Giotto Bizzarrini. Luxurious details abound, from hand-stitched leather seats and door panels to classic instrumentation and bespoke colour configurations. Notably, all gears feature synchronisers, enhancing daily usability. The original models rode on Pirelli tyres and Borrani wheels, complemented by a Koni-damped suspension system for exceptional ride quality by 1960s’ standards.

Technical Data

Special Editions and Collector Models

Special bodywork editions include the one-off 400 GT Flying Star II shooting brake, produced by Touring in 1966 as a more angular estate coupé, and the Monza 400, a unique US client commission by Neri e Bonacini intended for Le Mans entry. A handful of 400 GTS spyders and unique convertible conversions exist, usually inspired by the earlier 350 GTS.

Maintenance, Common Issues and Restoration

Restoration and maintenance require specialist knowledge, especially in sourcing original leather seals for the servo brakes and preserving or sourcing correct period parts such as Borrani wheels and Weber carburettors. The steel chassis and aluminium panels require attention to corrosion, and as with all classic V12 Lamborghinis, regular carburettor tuning and synchronisation are vital for optimal performance. Documentation and originality are highly valued among collectors.

Engine, Transmission and Handling

The 3.9-litre V12 offers a distinctive engine note and robust performance for the era. The manual five-speed gearbox, unique for its synchromesh rings on all gears, was engineered for precision. Thanks to Koni dampers and the Superleggera framework, the 400 GT delivers a composed ride and agility, complemented by spirited acceleration and high-speed poise. - 400 GT 2+2: Most widely produced at 224 units, notable for its improved interior space.

• Flying Star II: Unique for its wagon-style body.
• Monza 400: One-off Le Mans-inspired variant.

Exterior and Interior Design, Comfort and Equipment

Carrozzeria Touring’s Superleggera methodology yielded a flowing, lightweight body, often finished in bespoke colours. Interiors feature hand-fitted leather, high-grade dashboards with classic instruments, and thoughtful touches such as a large steering wheel for stable, confident driving. The 2+2 configuration provides surprising practicality, while special conversions and individualised interiors make each car unique. Low-profile roof pillars and extensive glass areas improve visibility and luminosity. Options like Borrani wire wheels or special paint finishes are common among restored examples.

Other Notable Features

The original factory employed highly skilled artisans for stitching and assembly, with attention to detail unmatched among many contemporaries. Numerous restoration projects retain these values, aiming for pure authenticity down to the smallest trim detail. The influence of the 350 GT and the rare opportunity for spyder conversions make each chassis an individual expression of Lamborghini’s early engineering and design philosophy.

Summary

The Lamborghini 400 GT exemplifies the exclusivity and technical sophistication of late 1960s Italian grand tourers. Its blend of performance, comfort, hand-built artistry, and rarity ensures a special presence among Lamborghini classics and secures its status as a sought-after collector's piece for connoisseurs of Italian automotive history.
