Lamborghini's new V12
Lamborghini's new V12 will be installed in the|
Murcielago successor, which is due next year.
15th November, 2010
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 litre displacement, output of 525 kW (700 hp) and maximum torque of 690 Newton metres 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 fuel 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. The new powertrain will enter production in early
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 line-up.
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
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,
Murcielago 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 taken their place in history as automotive classics.
The next milestone in this glorious history now awaits - Lamborghini's research and development engineers
started with a clean sheet of paper to make an all-new high-performance power plant. The resulting package is
extremely powerful and high-revving, yet compact. At 235 kilogrammes, 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 metres 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 aluminium-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 match 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 make the world's
most emotional gearshift feel.
This innovative manual gearbox combines extremely fast shift times - almost 50 per cent 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 kilogrammes - a distinct benefit, even
against comparable DSG transmissions, which are considerably heavier.
