One look at the pictures shows that the engine triumphs in the form stakes. Complex castings are there in numbers, their intricate shapes highlighting their function. However, when it comes to engines, V12 or otherwise, function generally outstrips form and, when we look at the figures, this is certainly so.
The new engine has a displacement of 6.5 litres, from which it outputs 525kilowatts, or 700 horsepower, in the Queen’s English. Add a stunning 690 Newton metres’ torque and we’re talking about an engine that means business. The torque figure peaks at 5,500 rpm, while peak power is to be found at a loftier 8,250rpm. All this is from a package that weighs a mere 235 kilograms. Outstanding power to weight ratio, anyone?
Yet power output is represented by more than bald figures, as Lamborghini well knows. To quote Lamborghini, ‘ 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.’
The impressive new V12 has a new stablemate and companion. Lamborghini has also developed a new power train, the ISR transmission. ‘ISR’ stands for ‘Independent Shifting Rod’ and it is this mechanism that gives remarkably low gear shift times. This is in a transmission that weighs just 79 kilograms.
The ISR transmission will join the new V12 engine next year, in the successor to the Lamborghini Murciélago.
