Lamborghini 400 GT
1966–1968 · Lamborghini 400 GT — Grand Tourer, V12, designed by Carrozzeria Touring.
The Story
If the 350 GT proved Ferruccio could build a car, the 400 GT proved he could build a company. Launched at Geneva in 1966, it enlarged Bizzarrini’s V12 to 4.0 litres and 320 hp, added proper 2+2 seating, and — crucially — replaced the bought-in ZF gearbox with Lamborghini’s own in-house transmission, complete with Porsche-style synchromesh. This was the moment Sant’Agata became a manufacturer rather than an assembler.
The body was again by Carrozzeria Touring, though after the great coachbuilder’s 1967 bankruptcy, production passed to Marazzi. The 400 GT was Lamborghini’s first genuine commercial success — 247 built — and the car that established the upstart as a credible rival to Ferrari and Maserati, just as the mid-engined Miura was about to rewrite the rules entirely.
It’s the definitive expression of Ferruccio’s original idea: a fast, refined, beautifully engineered grand tourer with no motorsport pretensions — the last and best of the front-engine ‘gentleman’s Lamborghini’ before the supercar era erupted.

Studio Motors POV
The 400 GT is the connoisseur’s early Lamborghini — the one that made the company real, overshadowed by the Miura but arguably the more important car. We rate a documented ‘Interim’ as a quietly blue-chip grail.

Provenance
Owners & what to look for
Famous Owners
No individual owner is firmly documented in this pass; collector- and museum-held. A 1966 400 GT ‘Interim’ fetched ~$885K at auction in 2025. (We don’t guess owners.)
Studio Buyer’s Brief
The 23 ‘Interim’ cars are the rarest and most valuable; standard 2+2s trade ~$400K–700K, Interims far higher. Matching numbers, the correct in-house gearbox and original Touring/Marazzi bodywork drive value — verify engine and box are right.

Questions
400 GT FAQ
How many Lamborghini 400 GTs were made?
Exactly 247 Lamborghini 400 GTs were produced: 224 standard 2+2 cars and 23 Interim models, which paired the 350 GT body shell with the new 4.0-litre V12 engine. The rarer Interim cars are the most sought-after today.
What is the Lamborghini 400 GT Interim?
The 400 GT Interim comprises 23 cars built during the transition between the 350 GT and the 400 GT, using the earlier 350 GT body fitted with the new 4.0-litre V12. They are the rarest 400 GTs and the most valuable, with one selling for approximately $885,000 at auction in 2025.
How does the 400 GT differ from the Lamborghini 350 GT?
The 400 GT enlarged the Bizzarrini V12 from 3.5 to 4.0 litres and raised power from 280 to 320 hp. It also added proper 2+2 seating, replaced the bought-in ZF gearbox with Lamborghini’s first fully in-house manual transmission, and became the brand’s first real commercial success.
How much does a Lamborghini 400 GT cost today?
Standard 400 GT 2+2 examples typically trade in the low $300,000s, with concours examples and rare Interims commanding strong premiums — one rare 23 Interim achieved approximately $885,000 at auction in 2025. Matching numbers and the correct in-house gearbox are key authentication points.
