● V12 engine without compressed air. It has been at the heart of Lamborghini since 1963, in fact. To date, only two V12 engines have been produced in super sports cars. The first model is the base engine for racing cars. It was designed by Giotto Bizzarrini and debuted in the first Lamborghini 350 GT.. The second generation was completely redesigned but still based on the original technical concept. First installed in the Aventador family and introduced in 2011, this was a significant technological advance for the company. As well as setting new standards in terms of engine power and reliable performance.
● The first generation engine has been refined and improved over time. to increase the power of the engine to be higher and after that also consider fuel economy and reduce emissions of burnt gases as well During the years 1963-2010, this engine was installed in several positions in the car. First fitted to the front of the 350 GT, 400 GT and Espada cars, it was developed to use aluminum for the cylinder head, crankcase and pistons to reduce weight to 232 kg. The driver rotates 90 degrees horizontally in the middle of the body car in the Miura series, and later rotates another 90 degrees in the middle of the rear body longitudinally. It was initially used in the Countach family of cars to improve the balance of weight distribution.
● As the engine capacity increases from 3.5 liters in the 350 GT to 6.5 liters in the Murciélago, weight had to be reduced. For this reason, the company took the initiative to use new materials and technologies to reduce the weight of the engine on frame, chassis To this day, the V12 engine remains at the heart of Lamborghini’s Aventador, Sián and Countach LPI 800-4, as well as the Essenza SCV12, a sports car that produces up to 830 horsepower.
The origin of valuable power
● From the outset, the V12 engine has been regarded as the most refined and brilliant powerhouse. Which received even more feedback when installed in various models of Lamborghini cars Bizzarini created the V12 engine just to give the company a chance to step into the world of motorsport, but Ferruccio Lamborghini turned it into an engine for new production cars. Until it became a fascinating story about motor vehicles that continues to this day
● “Lamborghini’s story begins with the V12 engine,” said Lamborghini’s former chief technical officer, Maurizio Reggiani. The V12 engine represents the pinnacle of technology, luxury and the character of a true sports car.”
● After being used in the 350 GT and other successors, the V12 engine was used in the Miura in 1966 and the Countach in 1971, and in the Diablo in 1990, before being used in the final model, the Murciélago Mae’ this engine has clearly proven its overall performance. When engineers designed a 5.2-litre version of the engine for use in Lamborghini’s first super SUV, the LM 002, in 1986, a special version of the LM 002 was produced with a V12 engine. 7.2 liter engine power up to 700 horsepower, which was normally used in motorboats for offshore racing only.
A big change in concept
● With the invention of the double camshaft. This was the first engine design for a car. Helps to increase the “V” angle of the machine and achieve a lower center of gravity. A transverse engine was placed in the rear of the Miura for better weight distribution and a shorter wheelbase. The gearbox frame and differential are also integrated into the transmission system. To help make the overall assembly of the legendary super sports car more compact and stable.
Weight distribution is key.
● Aiming to improve the weight distribution efficiency of the Countach, the designers chose the original engine but changed its location to the center of the rear of the body and rotated an additional 90 degrees. The first in the 350 GT to ever go 180 degrees. They put a gearbox in front of the engine, which is almost the same. “In the cabin” certainly enough, in the final version. The Countach’s engine was able to increase its displacement to 5.2 liters, and a V12 engine was later approved in the 1986 Countach for the US market. This milestone was achieved through the use of an electronic fuel injection system. It replaces the carburettor to meet the stricter emissions requirements of the market.
● “With more capacity, making the engine longer This means we have to move the center of gravity to the back of the car,” says Reggiani. Therefore, we have to completely adjust the engine position setting. He used the engine to change the car’s center of gravity and that’s why the V12 engine in the Countach still exists today.”
Responds to four-wheel drive exactly to the point.
● Further development of the V12 engine began in 1985 in preparation for the new Diablo super sports car, which was discontinued in 1990. Engine displacement was increased to 5.7 liters and power 492 hp at 6,800 rpm, the Diablo VT version, which to end in 1993, the super sports car Lamborghini became the first to offer a four-wheel drive version. At the same time, the Diablo SV-R was developed for the Super Sport Trophy, making its debut as a race car at the 1996 24 Hours of Le Mans where a fleet of 32 Diablo SV-Rs competed. This is the biggest program that Lamborghini has ever participated in. Before it became the Super Trofeo Championship, first held in 2009.
● The 1998 Diablo GT, which was basically the first Diablo before the second. Will be released in 1999, has a major technical upgrade of the engine. The key is to use a throttle body for each cylinder. Its purpose is to increase the response of the throttle. This change is as important as stepping into the future. It looks like similar technology will also be installed in the new racing Huracán GT3 in 2023.
A new challenge with Murciélago developments.
● When Audi (Audi) buys a majority stake in Lamborghini. So the period of great changes has begun. The new owner realizes that Lamborghini wants to maintain its identity and uniqueness. “We managed to create a clear relationship between Audi and Lamborghini and continue to respect each other’s needs,” said Reggiani. Audi understands what Lamborghini can and cannot ask for. This helps to balance the development of both companies by promoting their different strengths. Because of Lamborghini’s unique identity, shareholders and other brands are well aware of it. is the key to our success. What we offer through the development of the V12 gives us the confidence to improve the performance of the V10 engine first seen in the Gallardo, as well as further develop our other products, in a unique way.
● When under a new owner. Therefore, a different approach was taken to further develop the V12 engine. The focus is on quantitative efficiency in order to comply with increasingly stringent regulations. One example is the Murciélago, which started in 2001 with a 6.2-liter V12 engine producing 580 horsepower, which was later updated in 2007 to a 6.5-liter engine and delivered an impressive power of up to 670 horsepower. It can also make the car lighter up to to 100 kg, including several engine upgrades, such as the dry pump, which allows Lamborghini to reduce the distance between the crankshaft and the base of the car helping to improve the way the car handles even better
● With the development of the V12 engine in the Murciélago, Lamborghini gained its own unique position within the Audi world. And on top of that, the decision to design the V12 completely new allowed Lamborghini designers to set new goals and take advantage of new opportunities of the last 45 years.
A new design in every detail of the Aventador.
● “When you start designing a completely new engine from scratch. What you have to consider from the outset are the boundary conditions you have to maintain in any form and from any perspective,” says Reggiani. Achieved goals in terms of power, weight and efficiency. Including the durability that the group of companies want from us. the results are obvious Because we can sell this car twice as much as we initially expected. And this is a good indicator of the success of the Aventador, despite years of change and optimization. But from an engineering point of view the engine is still as good as ever.”
● “At the time when we started working with the Murciélago we had a 6.2-liter engine with an average power of 620-640 hp, but with the Aventador we started with a 6.5-liter engine with 700 hp. The engine power needs to be increased by at least 10%, which is a very big challenge. Because we meet Euro 5 emissions standards and remember this is a production engine project. The new Lamborghini, the first project under the Audi umbrella. This causes us to face various requirements set by many companies.”
● The Aventador’s engine debuted in 2011, delivering 690 hp at 8,250 rpm with a displacement of 6.5 liters, which was later modified for use with the LP 700-4 in 2013 and the LP 750-4 in 2013. 2015, the location in the Superve 2016, and the SVJ in 2019, with power increasing to 759 hp, and in 2021 the Ultimae, the last road car in the Aventador family, with 780 hp. It was also installed in Essenza where it was used only on the track and therefore was not restricted by the demands of road running. Where this modification can increase the power of the engine to 830 horsepower, so it is impressive. A real new era of engineering. “Our flagship V12 offering is the Essenza V12, with the same engine delivering 830 horsepower,” said Reggiani. But the exhaust back pressure is lower. Because there is no need to install filters and sound insulation equipment. The air intake filter has a lower pressure reduction rate. bringing you higher quantitative efficiency From a production perspective, the V12 engine is proof that developing a good engine from the ground up can create something uniquely aesthetic and powerful. which is a great achievement.”
● The Aventador is the last Lamborghini model to feature a naturally aspirated V12 engine. Before the brand steps into the hybrid engine era which will be launched in the first quarter of 2023
