British luxury carmaker Rolls-Royce has confirmed it is making its first sport utility vehicle (SUV), which would offer "the luxury of a Rolls-Royce in a vehicle that can cross any terrain", according to the company.

The firm has not labelled the vehicle as an SUV, and is calling it an 'Everywhere Vehicle' and promoting it with the hashtag, #EffortlessEverywhere. The new vehicle will be a "high-bodied car, with an all-new aluminium architecture", according to a letter from top executives.

There have been rumours for years that Rolls Royce is preparing to introduce an SUV to rival Porsche's Cayenne, Mercedes-Benz's G-Wagon, Land Rover's Range Rover, and Bentley's Bentayga.

"Many discerning customers have urged us to develop this new car – and we have listened. At Rolls-Royce Motor Cars we are uniquely focused on the desires of our customers and are driven by our own thirst to innovate," chairman Peter Schwarzenbauer and CEO Torsten Mueller-Oetvoes said in a joint open letter.

"This car will embody all the values and capabilities that drove our two Founding Fathers to secure Rolls-Royce's reputation, early last century, by taking top honours in rigorous overland adventures such as the Scottish Reliability Trials, the London to Edinburgh event and the Alpine Trials."

An Open Letter from the Chairman and the Chief Executive of Rolls-Royce Motor Cars on the subject of a new Rolls-Royce Why advertise with us The launch of Phantom in 2003 marked the beginning of the renaissance of Rolls-Royce Motor Cars. Since then, we have set a new benchmark for what a super-luxury car should be – unique, hand-crafted, beautiful and rare. Often imitated, Phantom has never been equalled and continues to be hailed as 'The Best Car in the World' by our customers and media alike. Twelve years later, after the introduction of successful new models like Ghost and Wraith, Rolls-Royce stands proudly at the pinnacle of British luxury manufacturing, confirming our custodianship of this precious marque. Now we have reached another seminal moment in Rolls-Royce's 111-year journey. Today we confirm that we are developing an all-new Rolls-Royce with exceptional presence, elegance and purpose: •A car that offers the luxury of a Rolls-Royce in a vehicle that can cross any terrain •A car that meets our customers' highly mobile, contemporary lifestyle expectations • A Rolls-Royce that is as much about the pioneering, adventurous spirit of Charles Rolls as it is about Sir Henry Royce's dedication to engineering and innovation •A car that appropriately reflects Rolls-Royce's brand promise of effortless luxury •A high-bodied car, with an all-new aluminium architecture •A unique new motor car worthy of carrying the Spirit of Ecstasy into the future This new Rolls-Royce will be Effortless ... Everywhere. Many discerning customers have urged us to develop this new car – and we have listened. At Rolls-Royce Motor Cars we are uniquely focused on the desires of our customers and are driven by our own thirst to innovate. So we challenged our engineers and design team, led by Director of Design Giles Taylor, to create a different and exceptional new car. This car will embody all the values and capabilities that drove our two Founding Fathers to secure Rolls-Royce's reputation, early last century, by taking top honours in rigorous overland adventures such as the Scottish Reliability Trials, the London to Edinburgh event and the Alpine Trials. Rolls-Royces conveyed pioneers and adventurers like Lawrence of Arabia across the vastness of unexplored deserts and over mountain ranges. In other parts of the world including Australia, India and the Americas, Rolls-Royces carried their owners over challenging terrain with absolute reliability and comfort. History sets our precedent and our future calls us to action. This new journey begins now. We will take our time in developing and perfecting this new concept in luxury. We will include our customers, enthusiasts and media along the way and will keep you informed of our progress. Until then, rest assured, we are creating a motor car in the greatest traditions of our marque. Sir Henry Royce famously said: "When it does not exist, design it". We are doing just that.

The company, well-known for its Phantom, Ghost and Wraith models, had been reluctant to enter into the SUV segment as it was unsure about how an SUV would work with the Rolls brand.

However, it seems to have changed its mind given the significant growth in SUV sales in the UK. SUVs represented 12% of the UK market in 2015, up from 6.5% in 2009, according to industry data.

By 2016, one in every five vehicles sold in the world will be an SUV, according to research firm IHS.
