THE first Aston Martin DBX five-seat SUV will roll off new production lines in South Wales in Spring 2020

Breaking new ground for the 106-year-old luxury British marque, the DBX was unveiled simultaneously at the Chinese Motor Show in Beijing and at the £250 million assembly plant atSt Athan in the Vale of Glamorgan .

The DBX marks a significant step for Aston Martin as the first of its current vehicles to be built outside its home plant of Gaydon, Warwickshire and the fourth model in the company's Second Century Plan, conceived and implemented by AML president Dr Andy Palmer.

Dr Palmer said of the newcomer: "I can't emphasise enough how incredibly exciting and significant DBX is for Aston Martin. Through its development alone, this beautiful SUV has already taken the company into new territories and in inspiring directions.

"This is a real landmark for this great British brand and I promise that DBX will reward all who experience it in their everyday lives."

He took over Aston Martin in 2014 and immediately launched a progressive development plan to transform the perennially struggling prestige brand and which included development of the DBX SUV and its new global manufacturing centre at St Athan.

Work on creating the St Athan vehicle assembly plant was started three years ago and its workforce is predominantly 750 locally recruited people, but that figure could rise with additional models and demand.

Staff have been trained at Gaydon and have gained experience at St Athan building engineering "mules" for development and systems testing.

Dr Palmer has already said St Athan will be home to future high performance luxury electric models from Aston Martin Lagonda as well as a hybrid DBX.

The site includes a small test track and with the 4x4 abilities of the DBX a low hill was included and this will also become part of the customer handover facility at the plant, while its proximity to an airstrip will permit super-rich clients to fly in as well.

Shown at the Geneva Motor Show in 2015, the concept for the DBX has been steadily developed and road tested including its off road performance on closed forest stages used for Wales Rally GB as well as arctic and desert conditions around the world.

The DBX has a bonded all aluminium dedicated SUV platform usually seen on sports cars which means the kerb weight is just 2,245kg but its rigidity endows it with strong dynamics on or off-road.

Electrically adjustable air springs raise or lower suspension for any terrain or driver requirements using the 4x4 transmission.

Under the bonnet is a specially tuned version of the same 4.0-litre V8 engine used in other Aston Martin models, now delivering 550ps in the DBX and mated to an automatic nine-speed gearbox.

The indicated 0-60mph time is 4.3 seconds and maximum speed is just over 180mph.

The DBX will cost from £158,000 and it will be up against similarly large SUVs from Bentley and Lamborghini as well as a future Ferrari SUV.

The DBX's cabin is very roomy throughout for five people and will be offered with a host of optional extras, including a leather trimmed baby seat, heated front cup holders, all-weather floor mats, illuminated tread plates and a Field Sport pack, with gun cabinet and a shooting stick.

There will be 11 optional accessory packages for the DBX such as a Snow Pack which adds a ski bag, a roof-mounted ski rack and snow chains, a Touring Pack comprising a four-piece luggage set and cabin saddle bags and even a Pet Pack including a pet bed, a portable pet washer and a roll down bumper protector.

Interior trim sees special applications of materials and technology including wood and wool, a 12.3-inch driver display and 10.25-inch central infotainment screen.

Wales Economy Minister Ken Skates said: "Aston Martin's decision to locate its new manufacturing facility in St Athan has been a huge vote of confidence in the Welsh Government's can-do attitude and is a genuine testament to the reputation, dedication and skills of our work force in Wales.

"I am absolutely delighted that Aston Martin has taken the decision to make Wales its centre for electric vehicle and that the first DBXs will be coming off the St Athan production linenext year. It is another huge win for Wales and is an excellent and very tangible example of how Welsh Government support can act as the catalyst for further economic growth and job creation."
