“The power is up 40 PS, to 560, which is why it’s called LP560-4.” Converting from metric to American, 560 PS equals 552.33 horsepower. LP stands for a Longitudinale Posteriore engine placement and 4 represents the number of driven wheels. With the engine thus situated, the LP560-4 has a rear-biased weight distribution of 43/57 percent. The ten cylinders — arrayed in a ground-hugging, 90-degree V — get a larger bore versus their predecessors, bumping the V-10’s displacement up 0.2 liters to 5.2. Lamborghini employs direct injection here: It allows for a 12.5:1 compression ratio, a wider power band, and an 18-percent reduction in fuel consumption and C02 emissions. Peak power happens at a lofty 8000 rpm; max torque of 398 lb-ft comes in the form of a little bump in the plateau at the 6500-rpm mark.
But the increase in power alone doesn’t get the LP560 to the Superleggera’s motivation-to-mass ratio: The new car also weighs 44 pounds less than the outgoing Gallardo. Revised axles and differentials (including a 45-percent limited-slip rear) shave mass, despite the addition of a toe link on the rear suspension. Otherwise, the body’s weight remains essentially the same, even though the car is two inches longer than before. The more observant among you will notice that the front fascia comes to a point as on the Murciélago and the Reventón, and that the taillights, which previously reached up onto the deck, are now contained on the rear fascia, their Y-shaped LEDs giving off an unmistakably mil-spec vibe.
