    Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

     

    A milestone in the history of Lamborghini: The new twelve-cylinder and the new ISR transmission – Innovative technologies for a unique powertrain

    Automobili Lamborghini is embarking on a highly innovative chapter in the company's history with an all-new V12 power plant and a new, unique high performing transmission – the twelve-cylinder with 6.5 liter displacement, output of 525 kW (700 hp) and maximum torque of 690 Newton meters was developed with state-of-the-art technology from a clean sheet of paper. The result is a synthesis of breathtaking performance, high-revving exhilaration, low weight and moderate gas emissions. The perfect complement is a completely new transmission concept for super sports cars: the "Lamborghini ISR" automated manual gearbox combines minimal shift times and everyday usability with low weight and dimensions to guarantee that emotional sensation from gearshifts, which customers expect from a super sports car at the very top of the premier league. The new powertrain will enter production ear ly 2011.

    The legend of Lamborghini strongly relies on its extraordinary, unique V12 engines."This new power unit is not only the crowning glory of our product range, it is also part of our enormous investment in the future of the Lamborghini brand," says Stephan Winkelmann, President and CEO of Automobili Lamborghini. "With this new V12, we are heralding a technological leap that encompasses all areas of the company and our future model lineup. With a unique package of innovations, Lamborghini will redefine the future of the super sports car. This 700 hp engine, together with an all-new concept gearbox, will be the strong heart of the Murciélago successor next year."


    Top performance, low weight

    Twelve-cylinder engines are fundamental to the legendary Lamborghini brand – in the past and in the future. The very first model by Ferruccio Lamborghini, the 350 GT, first appeared on the market in 1964 with a twelve cylinder power unit that was extremely innovative for its day. Miura, Espada, Countach, Diablo and, most recently, Murciélago are just a few of the super sports car to have been built in Sant'Agata. All of them were and will be driven by V12 engines – and all have long since taken their place in history as automotive legends.

    The next milestone in this glorious history now awaits – Lamborghini's research and development engineers started with a clean sheet of paper to create an all-new high-performance power plant. The resulting package is extremely powerful and high-revving, yet compact. At 235 kilograms, it is also extremely lightweight – with every single kilo of engine weight representing around three hp of maximum output.


    High-revving joy, stunning sound

    Even in the world of super sports cars, 515 kW (700 hp) at 8,250 rpm sets a new benchmark. Maximum torque stands at 690 Newton meters and is available at 5,500 rpm. The extremely well-rounded torque curve, beefy pulling power in every situation, incredibly spontaneous responsiveness and, not least, the finely modulated but always highly emotional acoustics make this engine a stunning power unit of the very highest order. Not only was it developed entirely in-house by Lamborghini, it is also manufactured from start to finish at company headquarters in Sant'Agata Bolognese. Highly qualified specialists assemble the engines by hand, with every single one then tested extensively and finely calibrated on an engine test bed.

    This exceptional athlete derives its power from a whole package of innovative technologies. For optimum weight, the crankcase and the four-valve cylinder heads are made from aluminum-silicon alloy. The short-stroke layout ensures exceptional high-revving performance and very low internal friction. A lengthy process of fine tuning perfected the thermal management system for the high-performance power unit, as well as the oil circulation system with dry-sump lubrication. The intake system with four individual throttle valves is highly complex – an extremely well-rounded torque curve and outstanding pulling power across the rev range the reward. The exhaust system delivers the lowest emission levels, as well as that unmistakable, spine-tingling Lamborghini sound – from a moderate rumble when cruising through the city at low revs to the howling crescendo of gears at their limits.


    Innovative transmission for maximum performance

    Engineers working under the sign of the bull have come up with an ingenious mate for the new twelve-cylinder engine in the shape of the Lamborghini ISR transmission. Overall, this is a drive unit that is absolutely unique in the competitive world of super sports cars. The development target was clearly formulated – to create the world's most emotional gearshift feel.

    This innovative manual gearbox combines extremely fast shift times – almost 50 percent shorter than with a dual-clutch transmission – with the benefits of manual shifting when it comes to low weight and compact dimensions, both always crucial for a super sports car. The low shift times are enabled through the transmission's particular design, known as ISR (Independent Shifting Rod). Instead of taking place in series, as with a conventional gearbox, shifting can occur virtually in parallel. While one shifting rod is moving out of one gear, the second shifting rod can already engage the next. Moreover, the transmission weighs only 79 kilograms – a distinct benefit, even against comparable DSG transmissions, which are considerably heavier.

    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Nice!

    I'd love to hear more about this new ISR system.  Anyone know who makes it? It doesn't seem that it's been sourced from Audi.


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    The new Lamborghini ISR transmission (ISR: Independent Shifting Rods) - Innovative servo-actuated mechanical gearbox for maximum performance

    However, it is not the engine alone that defines the character and driving characteristics of a super sports car. Another key element is the transmission. The demands are clear - the ratios must be perfectly arrayed and enable optimum power delivery from the engine. For maximum vehicle performance, shift times should be less than the blink of an eye. Operation must be clear and straightforward, via two ergonomic shift paddles behind the steering wheel. The characteristics of the transmission must be in line with the wishes of the driver at any given point - from smooth city cruising through to tough action on the racetrack. And, not least, Lamborghini customers expect an emotional shift feeling that ensures the sports car's reactions can always be felt and understood. Thus, the development objective was clearly formulated in this respect, too - create the world's most emotional gear shift.

    For all these reasons, the engineers in the R&D Department opted for a robotized gearbox as the "companion" of the new V12 power unit - however, in a very special iteration: the Lamborghini ISR transmission. This robotized gearbox combines extremely fast shift times, almost 50% less than dual-clutch transmission with the benefits of a manual transmission in terms of weight and compact dimensions - both always critical for super sports cars

    Unique engineering for supersportscars

    The new unit is laid out as a two-shaft transmission with seven forward gears and one reverse. For especially high durability, the synchronizing rings are made from carbon-fiber - a material with which Lamborghini has enormous experience. The short shift times are facilitated by the special design of the transmission, known as ISR - Independent Shifting Rod.

    To summarize the principle - in a conventional manual gearbox, be it automated or fully manual, the gear wheels for, say, second and third gears are located side by side. When the driver wants to shift gear, the shifting sleeve with synchronizer unit is moved along the shifting rod from second gear through neutral to third gear. This requires twice the distance and twice the time - second gear has to be disengaged before third gear can be engaged.

    Short distances, fast shift times

    This process is significantly shortened in the Lamborghini ISR transmission - the gear wheels from the second and third gears are separate from each other and the shifting sleeves are actuated by independent shifting rods. Now the shifting process can run virtually in parallel - while one shifting rod is disengaging one gear, the second shifting rod can already engage the next gear. Because these movements partially overlap and the mechanical distances are considerably shorter, this facilitates a significant saving in shift time. Overall, the Lamborghini ISR transmission shifts around 40 percent faster than the e.gear transmission in the Gallardo. And that is already one of the world's fastest automated manual gearboxes.

    Compact construction, low weight

    The new transmission has four of these independent shifting rods, with sensors constantly monitoring their exact positions. They are operated via hydraulic actuators, with an extremely high system pressure of 60 bar ensuring the necessary operating speed. The system incorporates a total of seven hydraulic valves, with pressure supplied by an electric pump. The double-plate clutch is also hydraulically actuated. All system components are contained within one casing. The total weight of the transmission is only 70 kilograms - a distinct advantage, especially compared with the significantly heavier dual-clutch transmissions from the same category

    Three operating modes for all situations

    Lamborghini drivers can choose between three operating modes - the Strada mode offers highly comfort-oriented shifting, with fully-automatic also an option. The Sport mode has a dynamic set-up in terms of shifting points and times, while the Corsa mode delivers the maximum shift strategy for race track driving. This mode also includes Launch Control, the automatic function for maximum acceleration from a standing start.

    With the Lamborghini ISR transmission, engineers working under the sign of the bull have devised an ingenious mate for the new twelve-cylinder power unit. Their work has created an overall powertrain that is absolutely unique in the world of super sports cars.

    Integrated electronic control system

    The excellent performances are possible only by a fast communication architecture through the several powertrain ECU's and considering the powertrain as ONE-system (un unico sistema) in the car.
    The fully electronic controlled coupling device for the front wheels (the ‘old' viscous coupling) is another key point of the powertrain: it is able to continuously distribute the right torque to the front wheels for always attaining the best performance aspired to by the driver. The torque distribution to the front wheels can vary continuously from 0% to 60% of the total torque available.

    ISR gearbox is basically just an further development of single clutch sequential manual. Nothing more. Wait when you hear about how long will the clutch last...

    That's true. But they improved a lot since the Diablo nasty Manuel  and the 1gen Gallardo E-gear.

     Sounds pretty hollow if you ask me...the old one sounded much, and i mean, MUCH, better. Maybe thats due to the direct injection ? Smiley


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Hollow sound usually means light internals...


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

     I don't really care what it means, as long as it doesn't sound right :) It sounds like it has no soul what so ever. Now I know why they used the Lp560 everywhere they tested the car, to hide the lackluster sound which most probably would have affected initial deposits for the car Smiley


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

     Sound, schmound. No one actually buy cars based on the sound.


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Really ?? I thought that was the second main reason after looks. At least in the supercar bussiness, which is all about emotion and shit :! And in the end, that's what sets this cars apart in the first place: their LOOKS/SOUND. Many people prefer to own a carrera Gt from say, a ferrari enzo, simply because they like the looks and the sound it makes better. Even if it's slower.

    Oh and, why do you think lamborghini struggles so much in this press-release to convince readers about the "High-revving joy, stunning sound" their new engine is capable of ? Surely, because they know that that is one of the main selling points of their cars, and what their potential customers are interested in.


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Finally, a clip where it isn't trailed by the Lp560 ! Like I said, it sounds pretty hollow, compared to the old model at least, maybe in real life it gets better though ! Just go to 3:30:

    Doubt it. First comes cost (obviously,) then comes looks, then performance, then sound and all that other stuff. Regardless of how great it sounds, if looks are the leading reason for the purchase, then it doesn't really matter what it sounds like. No one is going to buy a worse looking car that sounds better. Also no one will buy a significantly worse performing car just because it sounds better. You can't have a mean sounding car that sucks...

    Sound is nice, but I highly doubt anyone has made a purchase based on sound. Sound is so easily manipulated too.


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Any info on how the engine/gearbox will be mounted?Gearbox to the front(like 911 and Diablo/Murcie)or engine front-box back(like Gallardo and all ather mid engined cars)?

    Here is the answer to your question.

     


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    BTW, ISR gearbox is made by Graziano(and it could be used in forthcoming top model from another Italian sportscar manufacturer...) and AWD is made by Haldex...

    Ok, here's how I see it. Supercars, in general, are not purchased based on their price. You forget that the guys who buy these kind of cars are millionaires/billionaires and don't really care about the price. If they like a car, they buy it, no matter the price. Then most supercars that cost over 200 k have similar performance, sure some are faster than others but they are all HIPERFAST. So that's why i think that the ultimate factors in the buying decision of a supercar is a combination of looks/sound (and I completely agree with what you said, that "regardless of how great it sounds, if looks are the leading reason for the purchase, then it doesn't really matter what it sounds like"; but that is a big "if". imho, the sound is one of the defining characteristics of a supercar, and at least in my case I know I wouldn't buy a ferrari enzo in stead of a pagani zonda or a carrera gt, even if I like the design of the enzo more; but that's subjective of course). Sure maybe there are some people that don't care about these, i.e. the ones who drive bugatti veyrons (the biggest piece of crap supercar imho, and also in RonDennis's ho; not to mention even Jensen Button sold his after just 1500 miles, that's how crappy it is), simply because it's the fastest car on the planet. But these are just tasteless people with lots of money, again imho.

     Could that be Ferrari my dear Kreso? Smiley Pagani is the obvious answer, but you said "top model" and Pagani has only one model anyway...

    FERRARI RULES!!!


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    If I understand correctly, the new Pagani Zonda will have a 6 liter twin-turbo V12 (from the Sl 65 black) with much greater torque which probably requires a much more stronger transmission than this one. Probably a dual-clutch a la bugatti veyron. Anyway, Zonda is dead, so I don't really care. 

    And yes, when I read his post I also thought about Ferrari, since they have also developed a new V12 for their future flagships (i.e Scaglietti/599 succesor, and maybe the F70), which most likely needs a different transmission than that used on the f458 (which was made specially for the Italia by Getrag, but is used also on the SLS; with some issues however because the SLS has 650 nm while Italia only 540 nm, and it was designed for ferrari's high-revving V8 in the first place ). By the way, their engine sounds much better than this one:

    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    zonda is dead ? utterly rubbish !

    As for the SLS - there are no issues as AMG is stenghtening the box....

    As for the Bugatti - without question a masterpiece of engineering - most reliable (one testcar is now well over 160k km without a single issue - and just voted by latest EVO with the SS as one of the all time greats....


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    BjoernB:

    zonda is dead ? utterly rubbish !

     

     Zonda IS dead, its successor soon will be unveiled. Just like Murcie IS dead.


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

     Yeah, but I meant Zonda's succesor. Why ? Because of the engine/sound. That made the Zonda what it is now, i.e. one of the most desirable cars on the planet, that is the heart and soul of any supercar, and this is way I think zonda is dead. They want to put a boring bi-turbo saloon engine (S65 AMG) in it, they must be mad. 

    As for the Bugatti, it is (imho) an overweight soulless butt-ugly pig, which happens to be the fastest pig on the planet.

    And the SLS has some issues with transmission response, almost every review i've read so far has complained about that.

     

     


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

    Sounds fine to me, im worried it'll look like the Reventon, same lights i can tell...


    --

    indeed shifting is ancient technology - so is a fuel burning engine..  I happen to like both :) 


    Re: Lamborghini reveals all-new 6.5L V12 engine and ISR gearbox

     so Zonda will not be called Zonda anymore ??? what will be the name H. Pagani choose 

     as to the SLS - I drove it over 1000km and can not say anything negative about it's transmission...
