The Lamborghini V12 refers to the flagship V12 engine used by Lamborghini. Lamborghini has had two generations of V12 engines through their history, both of which are developed in-house. The first generation Lamborghini V12 is a sixty degree (60 Â °) V12 petrol engine designed by Lamborghini, and is the first internal combustion engine produced by the company.

It first entered production in 1963 as 3.5 liters replacing 3,465 cubic centimeters (211.4 cuÃ, in) mounted on the first Lamborghini car, the Lamborghini 350GT. The engine remains in use for nearly fifty years, the last version of the 6.5 liter displacement installed at Lamborghini MurciÃÆ'Â © lago. Lamborghini stopped their first-generation V12 after Murcielago, choosing the new V12 that was first used on the Lamborghini Aventador.

Histori

When Ferruccio Lamborghini set out to compete with Ferrari, he signed Giotto Bizzarrini to design the engine for his car and, according to some accounts, gave him a bonus for each horsepower of what the Ferrari V12 could produce. Completed 3.5-liter (214Ã, Â ° C) V12, with minor repairs, then became 6.5 lit lit Lamborghini MurciÃÆ' Â © lago LP 640, and completed its service for Lamborghini with the last version of MurciÃÆ'Â © lago, MurciÃÆ'Â © lago LP 670-4 SuperVeloce.

Technical description

This engine is designed from the beginning to be a quad cam of 60 degrees V12 - as a deliberate humiliation for single sole per capet designs in Ferrari. When the 3.464-cubic-centimeter prototype (211.4 cuÃ, in) was tested in 1963, it was able to produce 370 horsepower brakes (276 kW; 375 PS) at 9,000 revolutions per minute (rpm), or nearly 107 horsepower brakes (80 kW 108 PS) per liter. Bizzarrini insists the engine is mechanically capable of achieving 400 brake horsepower (298 kW; 406 PS) at 11,000 rpm with an improved fuel system, but the design is considered adequate, and when mounted with a production carburetor, all additional systems, and removable for road use, the engine still makes 280 horsepower brakes (209 kW, 284 PS).

Over the years, this V12 engine has almost doubled in the first - displacement to 6,192 cubic centimeters (377.9 cm), and then to 6,496 cubic centimeters (396.4 cuÃ, in). It has seen modified cylinder heads to allow four valves per cylinder, Weber carburetor replacement with electronic fuel injection, and re-engineering lubrication system from wet to dry sump design. However, the engine that drives the MurciaÃÆ' lago LP 640 can now trace its lineage directly to the F1-inspired Bizzarrini design and his team more than forty years ago.

Ownership of Audi and Successor V12

Lamborghini moved to Formula One in 1989 when the FIA ​​banned turbocharged engines. Former Scuderia Ferrari designer/engineer Mauro Forghieri was assigned to design and build a new 3.5-liter V12 engine for use by the French Larrousse team in 1989. Dubbed Lamborghini LE3512 , ( L > amborghini E mendeminekan 3 . 5 liter 12 cylinder) which is 3.493Ã, cc (213.2 cuÃ, in), the 80  ° V12 engine is reported as the best sound engine of the new 3.5L naturally aspirated formula. Lamborghini representatives stated in the machine dà © Å © but the race, the Brazilian Grand Prix of 1989 in Rio de Janeiro, that they chose a lower ranking team to join Formula One (Larrousse was in third season using Lola chassis) as perceived in stage early in its development, 3512 would not be able to do justice to one of the teams that is usually closer to the front of the grid. Also, the front-running team already has existing engine suppliers (McLaren with Honda, Williams with Renault, Benetton with Ford, and Ferrari making their own V12 engines).

The Lamborghini V12 did impress many people in 1989 although it was unreliable, and the best engine results in the first year came thanks quickly but the crash tended to Larrousse driver Philippe Alliot when he qualified Lola LC89 in 5th position for the Spanish Grand Prix at Jerez, only 1.417 seconds slower than V10 McLaren-Honda from pole winner Ayrton Senna. Alliot then supported the performance by scoring the machine's first point in Formula One by completing sixth position in the race and setting the fourth fastest lap of the race in the process. Unfortunately, Alliot's teammate for the second half of 1989, former Ferrari rider Michele Alboreto, never came to overcome Lola or Lamborghini. In eight races for Larrousse, he recorded four DNFs, two failures for pre-qualification, one failure to qualify, and one place to 11 in Portugal.

The best appearance of Lamborghini V12 came when Larrousse driver Aguri Suzuki came in 3rd place at the famous 1990 Japanese Grand Prix at Suzuka. His time in Formula One (1989-1993) will prove frustrating even though poor reliability becomes the norm for machines, although it is used by Grand Prix winning teams like Lotus and Ligier who can boast driving talents like Derek Warwick (Lotus - 1990), and Thierry Boutsen (Ligier - 1991). In a 2014 interview, Warwick said about 3512 that it was "All the noise and did not go away".

In 1993 after four years in Formula One with just one significant result for the engine, Bob Lutz from Lamborghini's parent company Chrysler made a hand-shake deal with McLaren boss Ron Dennis for the team to test the LE3512 to evaluate its potential as a winning race. McLaren made a modified version of their 1993 racing car, McLaren MP4/8 dubbed MP4/8B, to test the engine (test car takes three months to be modified to fit the longer and heavier V12). Testing was completed by three World Champion Ayrton Senna, and future world champion Mika HÃÆ'¤kkinen at Silverstone Circuit in England and Estoril circuit in Portugal. After the first drive of his car at Silverstone, Senna suggested certain changes to Forghieri (less brutal 'top end' and lower mid-range), and he filled the engine power increased from 710 bhp (529 kW, 720 PS) to around 750 bhp (559 kW; 760 PS) and both drivers are impressed even though the engine is still somewhat unreliable (HÃÆ'¤kkinen reported large engine blew up during testing at Silverstone, though he managed to reach 5,226 km (3,260).a circuit about 1, 4 seconds faster than the MP4/8 race car team powered by a 680 bhp Ford V8 engine (507Ã, kW; 689 PS)). According to reports, Senna even wanted to race the engine at the Japanese Grand Prix believed that while reliability might be a problem, at least it would be faster than with a Ford-powered race car (ironically Senna would win in Japan and the last race in Australia with the existing MP4/8). Despite this, Ron Dennis decided to use the Peugeot V10 engine in 1994 due to a better commercial agreement that would provide long-term stability for the team and by the end of the 1993 season, the Lamborghini LE3512 had retired from the Grand Prix race after the Company was sold by Chrysler to the group Indonesian investors led by Tommy Suharto.

Lamborghini, which on all cars powered up with the words "Chrysler is powered by Lamborghini" (other than the all-white McLaren MP4/8B, even though its test machine was given a badge as Chrysler), is one of only five V12 engines in use. in a naturally aspirated era from 1989-2013, others came from Ferrari (1989-1995), Honda (1991-1992), Yamaha (1991-1992), and Porsche (1991). The only other 12 cylinder engine in Formula One during this period was a disaster effort by Life Racing Engine with their W12 engine and Subaru who reintroduced Flat 12 to the sport, both of which appeared in the first half of 1990.
