Lamborghini last year launched its final car powered solely by an internal-combustion engine in the form of the Huracán Sterrato. It means all future models from the Raging Bull will be electrified, starting with plug-in hybrids and eventually moving to electric vehicles.

The first plug-in hybrid from Lamborghini will be an Aventador successor, which will debut later this month. It will be followed later this year or early next by a plug-in hybrid Urus, a prototype for which has just been spotted.

Warning stickers on the prototype reveal it's an electrified model, and there's no missing the cover for a likely charging port on the driver side rear fender. The fuel filler cap is located in its regular position on the passenger side rear fender.

The Urus, which is Lamborghini's most popular model, was just updated last year to Urus S guise. A sportier Urus Performante was also added last year.

The Urus plug-in hybrid looks different than those other variants. It has a unique front fascia, plus a new hood that appears to be devoid of vents. The internals of the headlights are also new and are likely Volkswagen Group's next-generation matrix LED design, which promises to be brighter and more precise than the current technology.

It isn't clear what Lamborghini has planned for the powertrain. It's likely that it will be the Urus' current twin-turbo 4.0-liter V-8 paired with a single electric motor. Expect the electric motor to be integrated with the transmission, just like in the plug-in hybrid versions of the related Audi Q7, Bentley Bentayga, Porsche Cayenne, and Volkswagen Touareg.

With the aid of an electric motor, the Urus plug-in hybrid may become the most powerful variant in the Urus lineup, a title currently held by the 567-hp Urus Performante. A small electric range should also be possible, which would allow the Urus to travel in cities that place restrictions on vehicles without electric or low-emissions modes.

A version of the Urus' V-8 plug-in hybrid system is expected to power the Huracán successor, a car that is expected to arrive before the end of 2024.
