The Lamborghini 400 GT 2+2, produced between June 1965 and June 1968, represents a pivotal moment in the history of the Italian automaker. It was the first Lamborghini to be produced in significant numbers, moving the company beyond its initial focus on bespoke, high-cost grand tourers. Positioned as a more accessible (though still undeniably expensive) alternative to the earlier 350 GT, the 400 GT 2+2 aimed to broaden Lamborghini’s customer base while maintaining the brand’s commitment to performance and luxury. It utilized a larger engine and a more comfortable, spacious interior, accommodating four passengers in a 2+2 configuration. The model is significant for establishing Lamborghini as a serious competitor to established marques like Ferrari and Maserati.

Powertrain & Engine Architecture
The heart of the 400 GT 2+2 is its 3.9-liter (3929 cc) naturally aspirated V12 engine. This engine, designated as the Lamborghini Tipo 325, was a significant evolution of the engine first seen in the 350 GT. It featured a 60-degree V-angle, a robust cast iron block, and aluminum cylinder heads. The engine utilized a single overhead camshaft (SOHC) design per bank, operating four valves per cylinder (DOHC). Fuel delivery was managed by three twin-choke Weber 46 IDA carburetors, providing a responsive and powerful, though somewhat thirsty, fueling system. The engine produced 320 horsepower at 6,500 rpm and 276 lb-ft of torque at 4,500 rpm. The engine was mounted longitudinally in the front of the chassis. The 400 GT 2+2 exclusively used a five-speed manual transmission, sending power to the rear wheels.
Driving Characteristics
The 400 GT 2+2 offered a grand touring experience characterized by strong acceleration and a refined, albeit firm, ride. The 3.9-liter V12 provided ample power for effortless cruising and spirited driving. Acceleration from 0 to 60 mph was achieved in approximately 5.9 seconds, and the car could reach a top speed of around 168 mph. The five-speed manual transmission offered precise shifts, allowing drivers to fully exploit the engine’s powerband. Compared to the earlier 350 GT, the 400 GT 2+2 felt more stable and predictable, thanks to its longer wheelbase and improved suspension geometry. However, the car’s weight (approximately 2,866 lbs) did impact its agility, making it less nimble than some of its competitors. The steering, while direct, required a fair amount of effort, typical of the era.
Equipment & Trim Levels
The 400 GT 2+2 was relatively well-equipped for its time, offering a comfortable and luxurious interior. Standard features included leather upholstery, wood trim on the dashboard and door panels, and electric windows. Air conditioning was an optional extra, as were power steering and a radio. The interior layout was designed to accommodate four passengers, with comfortable seating and ample legroom for those in the front. The rear seats were somewhat smaller, best suited for shorter journeys. The dashboard featured a comprehensive array of gauges, including a speedometer, tachometer, oil pressure gauge, water temperature gauge, and fuel level indicator. The car was available in a range of exterior colors, with many customers opting for vibrant shades of red, blue, or silver.
Chassis & Braking
The 400 GT 2+2 utilized a steel tube chassis, providing a strong and rigid foundation for the car. The suspension system consisted of independent coil springs and transverse stabilizer bars at both the front and rear, offering a comfortable ride and good handling characteristics. The braking system featured disc brakes on all four wheels, providing ample stopping power. The steering was a worm-reduction unit, offering direct but relatively heavy steering feel. The car’s wheelbase was longer than that of the 350 GT, contributing to improved stability and ride comfort.
Market Reception & Comparison
The Lamborghini 400 GT 2+2 was generally well-received by critics, who praised its powerful engine, luxurious interior, and refined driving experience. However, some critics noted the car’s relatively high price and its somewhat heavy weight. Compared to the 350 GT, the 400 GT 2+2 offered more space and comfort, making it a more practical grand tourer. However, the 350 GT was considered to be more focused on performance and driving enjoyment. Fuel economy was predictably poor, averaging around 14.7-13.1 US mpg. Reliability was generally good, although maintenance costs were high, as with all exotic cars of the period.
Legacy
The Lamborghini 400 GT 2+2 played a crucial role in establishing Lamborghini as a major player in the high-performance automotive market. It demonstrated the company’s ability to produce a sophisticated and desirable grand tourer that could compete with the best from Ferrari and Maserati. Today, the 400 GT 2+2 is a highly sought-after classic car, prized by collectors for its rarity, performance, and historical significance. The engine, while requiring regular maintenance, is known for its durability and longevity when properly cared for. Values for well-maintained examples continue to rise, reflecting the car’s enduring appeal and its place in automotive history.
