The Rolls-Royce Cullinan marked the first time the British luxury marque expanded its horizons to the booming SUV segment, but the brand may not stop there: the Cullinan could be in for a hybrid powertrain.

That's the word from Top Gear magazine, which reported last week that a Cullinan hybrid is "definitely" in the cards.

We don't know when, but it appears Rolls-Royce is keen to expand the Cullinan's offerings. The SUV's standalone engine, the 6.75-liter twin-turbo V-12, may also be in for a power bump, too. As it sits, the engine makes 563 horsepower. Unnamed sources listed the hybrid variant and the potential power bump as two near-term offerings from the opulent SUV.

The idea of a Cullinan hybrid would be an about-face for Rolls-Royce. CEO Torsten Müller-Ötvös only last year said Rolls-Royce didn't need a hybrid. His comments came as many automakers quickly move to introduce electrified models, but at Rolls-Royce it seems demand for electrified cars couldn't be lower, the CEO alluded. He said last year that hybrids are merely "interim steps" and they are not a part of the company's strategy. Perhaps something has changed inside Rolls-Royce, most likely regulatory demands.

Parent company BMW Group also said electrified Rolls-Royce models are part of a broader strategy in the future, which appears to further undercut Müller-Ötvös' previous sentiment. 

Aside from the Cullinan, Rolls-Royce may have a second SUV in the pipeline that would slot beneath the Cullinan as a baby brother of sorts. Just don't think of it as the "entry-level" SUV from the brand. After all, nothing about Rolls-Royce has ever earned the phrase "entry level."
