Lamborghini has revealed details of the 525kW 12-cylinder that will adorn the engine bay of its new flagship. Lesser manufacturers are going for smaller engines and employing forced induction to add a little drama but it seems the big ol’ V12 is not quite dead. Lamborghini is bucking the trend with its all-new car that will, when launched in 2011, sport an all-new, high-revving, naturally aspirated beast of an engine. The 6.5-litre V12 generates a heart-thumping 525kW at 8250rpm and 690Nm and is complemented by a new automated manual gearbox that clams to shift in half the time of a dual-clutch gearbox. The ISR (Independent Shifting Rods) transmission will allow the driver to choose from three modes for a mix of road and track settings.EFFICIENT AS POSSIBLECreated from scratch at Sant’ Agata and assembled entirely by hand, the new engine weighs only 235kg, making it 18kg lighter than the V12 in the erstwhile Murcielago. However, the new car was created from the outset to be as efficient as possible and will have a multitude of aluminium and carbon-fibre parts to keep weight down and use tyres with a lower rolling resistance. The CO2 emissions for the new car will reportedly be 398g/km and it will consume 17.2 litres/100km, down from 495g/km and 22 litres/100km for the Murcielago. According to Lamborghini president and CEO Stephan Winkelmann this new car will “redefine the future of the super sports car” as the Miura, Countach, Diablo and Murcielago did before it.The still-unnamed replacement for the Murcielago (which was discontinued in May, 2010) will be unveiled at the 2011 Geneva auto show.
