Espada 400 GT: the legendary V12 Lamborghini

In 2022 @Lamborghini is celebrating the V12: the legendary 12-cylinder engine that has powered its most iconic cars for almost 60 years. They include the Espada 400 GT, which was the first four-seat vehicle by Lamborghini and was its biggest selling model for years. Encapsulating an exceptional approach to technical innovation, thanks to the front-mounted 4-liter Lamborghini V12 engine it was always an extremely fast grand tourer despite the step up in size. The “pure” V12 combustion engine in its final form will go out of production before the end of 2022, when the last Aventador Ultimae[1] is made. From next year, the heir to the Aventador will be fitted with a new plug-in hybrid version of the V12 engine. Ferruccio Lamborghini aimed to produce the fastest, most luxurious and comfortable grand tourer Ever since the start of his venture into automobile manufacturing, company founder Ferruccio Lamborghini stated his objective very clearly. He wanted to make the best grand tourer around: a sports car that was not only fast but also comfortable and luxuriously finished. Presented at the Geneva Motor Show in March 1968, the Espada 400 GT perfectly embodied this idea for over a decade. The Espada could comfortably seat four adults and had more space for both luggage and passengers than the 400 GT 2+2 (its predecessor) and the Islero 400 GT 2+2. In addition, the Espada featured truly outstanding finishing, with generous amounts of leather and other refined materials, as well as the option of fitting air conditioning. Power steering was introduced as an option in 1969 and it was included as standard from 1972 onwards. A version with automatic transmission was available from 1974. Taking the V12 engine to 4 liters The technical cornerstone of the Espada was the 60° V12 engine that was first produced in 1963 with a displacement of 3.5 liters, which had already been increased to 4 liters (3929 cc) in 1964. It is a remarkable example of engine development technologies, and it was capable of delivering 325 hp at 7200 rpm when it was first fitted in the Espada. This increased to 350 hp at 7500 rpm in the Espada Series II, which was presented in 1970. Fed by six Weber 40 DCOE side-draft carburetors, the V12 had a compression ratio of 9.5:1 (which increased to 10.7:1 from the Series II onwards) and two chain-driven overhead camshafts per bank. It weighed just 232 kg thanks to substantial use of aluminum to make not only the cylinder head but also the crankcase and the pistons. It was front-mounted in a position that was slightly further forward compared to the previous Lamborghini 350/400 GT engines, in order to make the interior roomier. Thanks to the large opening below the aluminum hood, it was easily accessible. The chassis was based on that of the 400 GT but it was lengthened so that the wheelbase reached 2650 mm and it was also widened, with the wheel track increasing to 149 cm. It had four-wheel independent suspension, with double wishbones and coil springs. In November 1968, an Espada “Lancomat” with hydropneumatic suspension went on display at the Turin Motor Show. The system was made available on demand, but in the end it was chosen by very few owners. The Espada was an extremely fast grand tourer that was capable of reaching a top speed of between 245 and 260 km/h and keeping up with the sportier Miura in most conditions. The Espada’s commercial success When it was first unveiled, the Espada was the fastest four-seat car in the world. Featuring boxy shapes as part of a highly innovative design by Carrozzeria Bertone, it proved to be a long-lasting commercial success. Its versatility and roomy interiors – despite a height of just 119 cm – meant that it was suitable for much more frequent use, thus significantly expanding the customer base. A total of 1226 cars were produced across the three series: 176 of the Espada 400 GT Series 1 between 1968 and 1969, 578 of the Espada 400 GTE Series II between 1970 and 1972, and 472 of the Espada 400 GTS Series III between 1972 and 1978. #lamborghini #espada #lamborghiniespada
