Lamborghini 400 GT: 247 Units, 1960s V12 Grand Tourer

The Lamborghini 400 GT stands as a pivotal chapter in the brand’s early history, marking the transition from raw prototype to refined grand tourer. Produced between 1966 and 1968, this model introduced practical 2+2 seating while retaining the visceral thrill of a naturally aspirated V12 engine. With values soaring past £1 million for pristine examples, it embodies the allure of 1960s Italian engineering excellence.

Genesis of a Grand Tourer Legend

Lamborghini entered the automotive world with bold ambitions, challenging Ferrari’s dominance in the high-performance GT segment. Founded by Ferruccio Lamborghini, the company debuted the 350 GT in 1964, which laid the groundwork for the 400 GT. This successor addressed key limitations of its predecessor, including interior space and power output, evolving into a more versatile machine suitable for long-distance cruising.

The 400 GT’s development reflected Lamborghini’s commitment to grand touring ethos—cars built for epic road trips rather than track dominance. Unlike the mid-engine supercars that would define later decades, the 400 GT featured a front-engine layout with rear-wheel drive, emphasizing comfort and accessibility. Only 247 units were produced, making it a rare gem today.

Design Mastery: Sleek Lines and Spacious Refinement

Carrozzeria Touring Superleggera crafted the 400 GT’s aluminum body, blending aerodynamic elegance with functional upgrades. Measuring 49 inches in height, it maintained a low-slung profile despite added roofline height for rear passengers. Thin A- and C-pillars and expansive glass areas provided exceptional visibility, creating an airy cabin that feels surprisingly modern.

Key styling updates included a revised front fascia with sleeker headlights and a more pronounced grille, distinguishing it from the 350 GT. The long hood and short deck accentuated its proportions, evoking classic GT poise. Interior materials featured leather upholstery and wood accents, with the 2+2 configuration offering genuine space for four adults—though rear seats were snug for taller occupants.

• Exterior Highlights: Aluminum body panels for lightweight strength; subtle fender flares for wider track.
• Interior Innovations: Redesigned dashboard with comprehensive gauges; improved legroom via wheelbase extension.
• Visibility Edge: Panoramic greenhouse unmatched in contemporaries.

Powertrain Excellence: The Bizzarrini V12 Heart

At the core lies a 3.9-liter all-aluminum V12 engineered by Giotto Bizzarrini, displacing from the 350 GT’s 3.5 liters to deliver 320 horsepower at 6,500 rpm and 374 Nm of torque. Six side-draft Weber carburetors fed the engine, producing a symphonic howl that builds progressively through the rev range. This power propelled the car to 168 mph top speed and 0-62 mph in 6.8 seconds—impressive for the era.

A five-speed manual transmission with synchromesh gears, sourced from ZF and refined for the model, ensured smooth shifts. Long gearing allowed relaxed highway cruising without constant gear changes, ideal for autostrada runs. Fuel economy hovered around 15-20 mpg, typical for such unbridled performance.

Behind the Wheel: A Time Capsule Drive

Sliding into the 400 GT transports drivers to the 1960s, where analog charm reigns. The steering is light yet communicative via rack-and-pinion setup, with hydraulic disc brakes providing confident stopping power. Suspension tuned for grand touring soaks up imperfections while maintaining composure in corners.

The V12 awakens with a mechanical symphony, urging revs toward redline. Power delivery is linear, rewarding momentum over explosive acceleration. On open roads, it excels as a high-speed cruiser, stable up to its limit. Wind and tire noise are present but add to the authentic experience.

• Handling Traits: Balanced chassis with slight understeer; responsive to throttle inputs.
• Braking: Girling discs all around, fade-resistant for period tech.
• Daily Usability: Surprisingly compliant ride for long journeys.

Collector Appeal and Market Dynamics

Today, the 400 GT commands premiums from £500,000 to over £1 million, driven by scarcity and provenance. Well-maintained examples with matching numbers fetch top dollar at auctions. Restoration costs are high due to bespoke parts, but the investment holds amid rising classic car demand.

Compared to rivals like Ferrari 275 GTB, the Lamborghini offers unique V12 character and 2+2 practicality. Values have appreciated steadily, with blue-chip status solidified by Lamborghini’s heritage recognition.

Special Variants and One-Offs

Beyond the standard 2+2, interim 400 GTs bridged the 350 GT with 23 units using the older body but new engine. The Monza, a 1966 one-off speedster, and Flying Star II show car on a shortened chassis showcased Touring’s versatility. These rarities amplify the model’s mystique.

Legacy in Lamborghini’s Evolution

The 400 GT bridged Lamborghini’s GT roots to supercar future, influencing models like the Espada and Islero. It proved Ferruccio’s vision: luxurious, powerful tourers rivaling Ferrari. Modern revivals echo its front-engine V12 purity.

Ownership Considerations

Prospective owners face maintenance challenges: carburetor tuning, rust-prone sills, and electrical gremlins. Specialist garages handle V12 rebuilds costing £50,000+. Insurance starts at £5,000 annually for collectors.

• Maintenance Tips: Annual fluid changes; store dry to prevent corrosion.
• Running Costs: Fuel-thirsty but reliable with care.
• Investment Potential: Strong appreciation trajectory.
