The 1967 Lamborghini 400 GT 2 + 2, first presented at the 1966 Geneva Auto Show, was built from 1966 through 1968. Lamborghini wanted to keep the same elegant proportions of the 350 GT while adding an additional two seats in the rear of the car. Designers lowered the floor pan and raised the height 2.6 inches to fit them in. The final result was a length of 184.5 in, width of 68.0 in, and height of 50.6 in.
Space was saved with a reversal of the rear control arms and a new shape for the rear window. To comply with upgraded US safety regulations, paired headlights were installed instead of sculpted units. Another difference from the 350 is the extra front wiper. Only a few of the 242 manufactured 400 GTs were right wheel drives.
With the exception of the trunk and hood, the body changed from aluminum to steel. The heavier steel increased durability and reduced costs of production. Springs and shocks were redesigned to handle the heavier vehicle. Carrozzeria Touring designed the bodywork, coordinating with engineer Giampaolo Dallara.
A 60° V12 engine with an aluminum alloy block was placed at the front in a longitudinal position. The powerful motor had a specific torque of 374.2 nm/ 276 ft lbs @ 4500 rpm. Displacement measured 3929cc, bore 82.0mm, stroke 62.0 mm, and compression 10.5:1.
The ZF transmission was exchanged for a Lamborghini-designed five-speed transmission with Porsche syncro rings on all five gears to reduce noise. A Lamborghini unit also replaced the Salisbury rear differential. The 350’s 6 Twin-Throat 40 DCOE Weber carburetors continued for the fuel feed.
Worm and Roller steering made the rear wheel drive vehicle easier to handle. Front and rear suspension included double wishbones with coil springs and telescopic shock absorbers. Girling disc front and rear brakes with Vacuum Assist stopped the 3199 lb exceptional 1967 400 GT Lamborghini.
