Strong predictions for the company's first off-roader.

Disappointingly, but perhaps understandably, Aston Martin is predicting that its upcoming Varekai SUV will be its best-selling model.

While that may be sad to hear from the maker of luxury sports cars, you might recall when Porsche introduced the similar Cayenne in the early 2000s, it too was a sales success and arguably saved the company, while also bankrolling the company's re-entry into the hypercar market.

With that in mind, Aston Martin going all boring and big car-y might not be the worst idea in the world.

The company aims to sell 3,850 a year, which is 500 units more than its predictions for the new Vantage. Its prediction came in its new share prospectus, which showcased the company to potential investors ahead of its long-awaited flotation on the London stock market later this week.

The Varekai will go up against the Porsche Cayenne, Bentley Bentayga, Lamborghini Urus, Rolls-Royce Cullinan, and Maserati Levante, as well as the upcoming Ferrari Purosangue which will be that company's first SUV too.

As well as shifting more units than any other model in its range, Aston Martin is also hoping to reach new markets and new customers, including women, with the SUV that was previously previewed with the DBX concept in 2015 (pictured). The new SUV is set to push Aston Martin's total annual sales above 10,000, and to help achieve that Aston Martin will be expanding its dealer network from 160 showrooms to 200.

That expansion will include six new locations in North and South America, bringing its number of retailers in the region – its largest by revenue – to 50. Meanwhile, the SUV will be built in Aston Martin's all-new factory in St Athan, in South Wales, starting next year. The facility will create 750 new jobs for the company, with 150 of those already being hired. When complete the plant will join Aston Martin’s Gaydon headquarters and Newport Pagnell as the company's production facilities.

The new car will come with a range of powertrain options, including Mercedes-AMG-sourced V8s and V12s, and the hybrid system that will be used in the recently unveiled AMG GT 4-Door Coupe. An all-electric version, like the drivetrain of the DBX concept won't be offered though as previously though. Instead, Aston Martin's other brand Lagonda will launch an electric crossover instead by 2021.
