According to a report by Motor1, the Urus PHEV could feature a plug-in hybrid powertrain borrowed from Porsche, including a twin-turbocharged 4.0-liter V8 and electric motor from the Panamera Turbo S E-Hybrid. The report states that "Lamborghini could tweak it to make upwards of 820 hp in top trim, with a less-powerful variant making around 675 hp." This would make the Urus PHEV the new flagship SUV for Lamborghini, surpassing the Urus Performante.
The test vehicle was also seen sporting a restyled front fascia, different lights, and a slightly altered hood, however, there have been no reported changes to the sides or rear of the vehicle.
Quoting the report, "With sightings becoming more frequent, we could see a reveal sometime in the first half of this year."
