Lamborghini is set to electrify its lineup with the successor to the Huracan, which will feature a hybrid setup similar to the Revuelto model. However, there is some uncertainty around the powertrain that will be used in the upcoming Huracan replacement. A recent spy video captures the exhaust note of the coupe, but it’s difficult to determine the exact type of engine responsible for the noise.

Last year, Lamborghini CEO Rouven Mohr mentioned that the Huracan’s successor would have between 6 and 12 cylinders. However, a later report suggested that the automaker might depart from the current car’s naturally aspirated 5.2-liter V10 engine and opt for a twin-turbocharged V8, similar to the one used in the Urus. The noise in the video is too loud to ascertain whether the test vehicle has 8 or 10 cylinders, but it does have a distinct raspy and guttural burble.
