An Engine and Transmission Tuned to the Extreme

Lamborghini has unveiled the new V12 engine that will power the successor to the Murciélago, set to debut next year. While there were rumors that the Jota name would be revived for the successor, the name Aventador has recently emerged as the likely candidate for the top model.

This engine was created from a completely blank slate at the Sant'Agata Bolognese headquarters. Following a long period of evolution, the development goals for the new engine were to achieve lighter weight, lower emissions, and even higher output compared to its predecessor. The 60-degree V12, compactly housed with a height of 665mm, width of 848mm, and length of 784mm, features a short stroke with a bore of 95mm and stroke of 76.5mm. The crankshaft weighs 24.6kg, and the engine itself tips the scales at just 234kg. In terms of specifications, it produces a maximum output of 515kW (700 PS) at 8250 rpm and a peak torque of 690Nm (70.4 kgm) at 5500 rpm. This represents an increase of 44kW (60 PS) and 30Nm (3.1 kgm) over the Murciélago's 471kW (640 PS) and 660Nm (67.3 kgm).

Furthermore, meticulous attention has been paid to tuning the engine's sound. The two mufflers produce distinct high and low tones, creating a sound that can truly be called the "Lambo sound."

The New V12 Engine

ISR Transmission

Developed alongside the engine is a robotized transmission. This 7-speed, two-pedal automated manual, known as ISR (Independent Shifting Rods), utilizes a single clutch. By employing independent shifting rods that function similarly to a dual-clutch system, it achieves gear changes approximately 50 percent faster than conventional dual-clutch transmissions.

This gearbox weighs a mere 79kg, with the adoption of ISR resulting in a 70kg weight reduction. This is considerably lighter even when compared to the DSG used by the VW Group. The ISR offers three selectable modes: Strada, Sport, and Corsa. The Corsa mode, which allows for the full expression of its performance, also features a launch control function.

The successor to the Murciélago, equipped with the new V12 engine and ISR transmission, is expected to be unveiled next year, likely at the Geneva Motor Show in March.
