Lamborghini 400 GT: 3.9 l V12, 2+2 coupe and what to check
Lamborghini 400 GT — the 2+2 grand tourer produced from 1966–1968 with a front-mounted V12, successor to the Lamborghini 350 GT. We look at the versions, engine, and what to check when evaluating such a rare collector's car.
400 GT in brief
The Lamborghini 400 GT debuted in 1966 as an update to the 350 GT. It features a front-mounted V12, rear-wheel drive, and 2+2 seating, with the body designed and built by Carrozzeria Touring Superleggera.
This is one of the earliest Lamborghini production cars. Around 250 units were made, making it a very rare collector's model today.
Versions and differences
The main version is the 400 GT 2+2 with four seats. There is also a two-seater 400 GT, but very few were produced.
Compared to the 350 GT, the 400 GT has a larger engine and a slightly modified body and interior. It was replaced by the Lamborghini Islero in 1968.
Engine and transmission
The Lamborghini 400 GT has a 3.9 l V12 petrol engine producing around 320 hp. The transmission is a 5-speed manual with rear-wheel drive.
This is a classic V12 designed by Giotto Bizzarrini, with two overhead camshafts per cylinder bank. Due to its complex design, maintenance and repairs are expensive.
What to check when evaluating a 400 GT
The most important thing is authenticity and documentation: body, engine, and chassis numbers, provenance, restoration work. Due to its rarity, the price heavily depends on originality, so the inspection should be carried out by a Lamborghini classic specialist.
Check the body for corrosion and poor repairs, the engine, gearbox, suspension, and brakes. Some parts are hard to find or made to order.
