With the Murcielago out of production, Lamborghini prepares itself for the launch of its replacement (some have called it the 'Jota', which I doubt would be the name) in 2011-2012. So how do they tell their fans, loyal customers and also the general public? They preview an important part of any top of the range Lamborghini ; the V12 engine.

It has been stated that the Lamborghini range topping cars must run a V12 engine. And the Murcielago replacement stated for launch next year will get a totally new Lamborghini engine and transmission. The Lamborghini V12 will have 6.5liters, similar in capacity to the outgoing Murcielago but it is a totally new engine without any major carry over parts. It will have a power output of 700bhp (up from the 670hp that the Murcielago LP670-4 makes) and a maximum torque of 690Nm.

The power will be channeled to the wheels via a new automated manual gearbox (called the Lamborghini ISR transmission or Independent Shifting Rod in full) that weighs 79kg and has a shifting time (according to Lamborghini) 50% faster than the equivalent DSG (heavier too) type gearbox. The engine weighs in at 225kg making this supercar drivetrain one of the lightest in the business.

The crankcase and the four-valve cylinder heads are made from aluminum-silicon alloy for a reduction of weight. The new V12 has a 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 with an extremely well-rounded torque curve and outstanding pulling power across the rev range the reward.

According to Lamborghini, the exhaust system delivers the lowest emission levels for a supercar, as well as that unmistakable, spine-tingling Lamborghini sound – from a moderate rumble when cruising through the city at low revs to the howling at their limits.

“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.”

With such an engine, expect a faster, lighter, more economical and more environmental friendly top of the line V12 Lamborghini by next year.
