The Series I was the first evolution of the Rolls-Royce Cullinan. It was introduced in 2018 for the 2019 model year, as an ultra luxury SUV featuring four wheel drive and power from a 6.75L twin-turbo V12. The Cullinan has a tall, upright design, with the famous Pantheon grille, and a strong, squared shape. Two variants were offered, a Base Model and a sportier Black Badge. Production of the Series I lasted until 2024, when it was replaced by the Series II Rolls-Royce Cullinan.
