The finished {{convert|3.5|litre|cuin|0|lk=on|adj=on}} V12, with minor improvements, went on to become the 6.5 litre powering the [[Lamborghini Murciélago#Murciélago LP 640 (2006–2010)|Lamborghini Murciélago LP 640]], and completed its service for Lamborghini with the final version of the Murciélago, the [[Lamborghini Murciélago#Murciélago LP 670–4 SuperVeloce (2009–2010)|Murciélago LP 670-4 SuperVeloce]].<ref>{{cite web|title=Lighter Murcielago here in 2008|url=http://www.autocar.co.uk/News/NewsArticle/AllCars/229128/|work=AutoCar.co.uk|publisher=© Haymarket Media Group|date=9 November 2007|access-date=4 January 2010|archive-url=https://web.archive.org/web/20080829204717/http://www.autocar.co.uk/News/NewsArticle/AllCars/229128/|archive-date=29 August 2008|url-status=dead}}</ref>{{clear left}}
==Technical overview== The engine was designed from the start to be a [[Overhead camshaft#Double overhead camshaft|quad cam]] 60 degree V12 - as an intentional snub to Ferrari's [[overhead camshaft#Single overhead camshaft|single overhead camshaft]] per-bank design. When the {{convert|3464|cc|1|adj=on}} prototype was tested in 1963, it was able to produce {{convert|370|bhp|kW PS|0|lk=in}} at 9,000 (rpm), or almost {{convert|107|bhp|kW PS|0}} per litre. Bizzarrini insisted the engine was mechanically capable of reaching {{convert|400|bhp|kW PS|0}} at 11,000 rpm with an uprated fuel system, but the design was judged adequate, and when fitted with production [[carburettor]]s, all the auxiliary systems, and detuned for road use, the engine still made {{convert|280|bhp|kW PS|0}}.<ref name=jalop>{{Cite web|url=http://jalopnik.com/5690495/a-farewell-to-the-old-lamborghini-v12/|title=A Farewell to the Old Lamborghini V12|date=15 November 2010 }}</ref>{{clear left}}
[[File:Lamborghini Murciélago with engine.jpg|200px|thumb|left|[[Lamborghini Murciélago|Lamborghini Murciélago Roadster]] with its [[V12 engine]] on display]]
Over the years, this V12 engine has nearly doubled in displacement - first to {{convert|6192|cc|1|lk=on}}, and later to {{convert|6496|cc|1}}. It has seen the modification of the [[cylinder head]]s to allow [[multi-valve|four valves]] per cylinder, the replacement of [[Weber carburetor|Weber]] carburettors with [[electronic fuel injection]], and the re-engineering of the lubrication system from a [[wet sump|wet]] to a [[dry sump]] design. However, the engine that powers the [[Lamborghini Murciélago#Murciélago LP 640 (2006–2010)|Murciélago LP 640]] can trace its lineage directly to the F1-inspired design of Bizzarrini and his team more than forty years ago.<ref name=jalop/>{{clear left}}

Lamborghini representatives stated at the engines début race, the [[1989 Brazilian Grand Prix]] in [[Rio de Janeiro]], that they chose a lower ranked team to join Formula One (Larrousse was in its third season using [[Lola Cars|Lola]] chassis') as it was felt at the early stage of its development the 3512 would not be able to do justice to one of the teams usually closer to the front of the grid. Also, the front running teams already had existing engine suppliers in place ([[McLaren]] with [[Honda F1|Honda]], [[WilliamsF1|Williams]] with [[Renault F1|Renault]], [[Benetton Formula|Benetton]] with [[Ford Motor Company|Ford]], and Ferrari who made their own V12 engines).
The Lamborghini V12 did impress many in 1989 despite its unreliability, and the engines best result in its first year came thanks to fast but accident prone Larrousse driver [[Philippe Alliot]] when he qualified his [[Lola LC89]] in 5th position for the [[1989 Spanish Grand Prix|Spanish Grand Prix]] at [[Circuito de Jerez|Jerez]], only 1.417 seconds slower than the [[V10 engine|V10]] [[McLaren MP4/5|McLaren]]-Honda of pole winner [[Ayrton Senna]]. Alliot then backed up that performance by scoring the engine's first point in Formula One by finishing 6th in the race and setting the 4th fastest race lap in the process. Unfortunately, Alliot's teammate for the second half of 1989, former Ferrari driver [[Michele Alboreto]], never came to grips with either the Lola or the Lamborghini. In his eight races for Larrousse he recorded four DNF's, two failures to pre-qualify, one failure to qualify, and a single 11th-place finish in [[1989 Portuguese Grand Prix|Portugal]].
The Lamborghini V12's best finish came when Larrousse driver [[Aguri Suzuki]] finished 3rd in the infamous [[1990 Japanese Grand Prix]] at [[Suzuka Circuit|Suzuka]]. Its time in Formula One (1989-1993) would prove to be frustrating though as poor reliability became the norm for the engine, despite being used by Grand Prix winning teams such as [[Team Lotus|Lotus]] and [[Equipe Ligier|Ligier]] who could boast driving talent such as [[Derek Warwick]] (Lotus - 1990), and [[Thierry Boutsen]] (Ligier - 1991). In a 2014 interview, Warwick said of the 3512 that it was "All noise and no go".
In 1993 after four years in Formula One with only one significant result for the engine, [[Bob Lutz (businessman)|Bob Lutz]] of Lamborghini's parent company [[Chrysler]], did a hand-shake deal with [[McLaren]] boss [[Ron Dennis]] for the team to test the LE3512 to evaluate its potential as a race winner.<ref name=forix>{{cite web|url=http://8w.forix.com/mc-lambo.html|title=McLaren's brief flirtation with the Chrysler empire|author=Rainer Nyberg|website=8w.forix.com|date=2001|access-date=2016-04-08|archive-url=https://web.archive.org/web/20160305002925/http://8w.forix.com/mc-lambo.html|archive-date=2016-03-05}}</ref><ref name=whatif>{{cite web|url=http://www.race2play.com/homepage/show_blog_posts/4226|title=What if Senna had driven a McLaren-Lamborghini in 1994?|publisher= F1 Racing|website=www.race2play.com|date=2011-04-04|access-date=2016-04-08|archive-url= https://web.archive.org/web/20140427030156/http://www.race2play.com/homepage/show_blog_posts/4226|archive-date=2014-04-27}}</ref> McLaren made a modified version of their {{f1|1993}} race car, the [[McLaren MP4/8]] dubbed the MP4/8B,<ref name=forix/> to test the engine (the test car took three months to modify to fit the longer and heavier V12<ref name=whatif/>). Testing was completed by triple World Champion Ayrton Senna, and future dual World Champion [[Mika Häkkinen]] at both the [[Silverstone Circuit]] in England and the [[Autódromo do Estoril|Estoril circuit]] in Portugal.<ref name=whatif/> After his first drive of the car at Silverstone, Senna suggested certain changes to Forghieri (a less brutal 'top end' and a fatter mid-range),<ref name=whatif/> and he complied with engine power increased from {{cvt|710|bhp|kW PS|0}} to approximately {{cvt|750|bhp|kW PS|0}} and both drivers were very impressed despite the engine still being somewhat unreliable (Häkkinen reported a massive engine blow up while testing at Silverstone,<ref name=whatif/> though he did manage to lap the 5.226 km (3.260 mi) circuit some 1.4 seconds faster than the teams MP4/8 race car powered by a {{cvt|680|bhp|kW PS|0}} [[Cosworth#The HB V8|Ford]] [[V8 engine]]).<ref name=forix/> According to reports, Senna even wanted to race the engine at the [[1993 Japanese Grand Prix|Japanese Grand Prix]]<ref name=forix/> believing that while reliability might be a problem (according to McLaren engineers, the most they got out of any of the V12s post-Forghieri's changes was 19 laps at Silverstone before the engine blew up), at least he would be quicker than with the Ford powered race car<ref name=whatif/> (ironically Senna would win in both Japan and the last race in [[1993 Australian Grand Prix|Australia]] with the existing MP4/8). Despite this however, Ron Dennis decided to go with [[Peugeot]] [[V10 engine]]s in {{f1|1994}} due to a better commercial agreement that would give long term stability to the team and at the end of the 1993 season, the Lamborghini LE3512 was retired from Grand Prix racing<ref name=whatif/> after the company was sold by Chrysler to an Indonesian investor group led by [[Tommy Suharto]].<ref name=forix/>
The Lamborghini, which on all cars it powered carried the words "Chrysler powered by Lamborghini" (other than the McLaren MP4/8B which was all virgin white, though the test engines were badged as Chrysler), was one of only five V12 engines used in the naturally aspirated era from 1989–2013, the others being from Ferrari (1989-1995), [[Honda F1|Honda]] (1991-1992), [[Yamaha Motor Corporation|Yamaha]] (1991-1992), and [[Porsche in Formula One|Porsche]] (1991). The only other 12 cylinder engines in Formula One during this time were disastrous efforts by [[Life Racing Engines]] with their [[W12 engine]] and [[Subaru]] who reintroduced the [[Flat 12]] to the sport, both appearing in the first half of 1990.
