The DBX SUV will become Aston Martin's best-selling vehicle after its launch next year, the company predicts.
The brand expects DBX sales to reach 3,850 a year, compared with an estimated 3,250 for the newly launched Vantage, the company's entry-level sports car.
The predictions were made in Aston Martin's share prospectus in which it outlined the company's plans to potential investors before the brand's flotation this week on the London stock market.
Aston also said it expected the DBX to be powered by the same twin-turbocharged 4.0-liter V-8 engine as in the Vantage and DB11 coupe, rather than a V-12. The AMG engine is supplied by Daimler and makes 496 hp in the DB11. The V-12 is supplied by Ford in an agreement that runs out in 2021, putting its future use in question.
Aston has said the DBX will help it reach new customers, including women. The brand plans to expand its dealer network, from 160 now to 200 "in the medium term," Aston said. That includes six more retailers in North and South America, its biggest region by revenue, to bring the number to 50.
The DBX will push Aston Martin sales beyond 10,000 a year by 2021, almost double last year's figure, the brand said. The DBX is expected to rival not just the Bentley Bentayga but the Lamborghini Urus and Ferrari Purosangue. Aston Martin is also readying an electric crossover to be launched under the Lagonda brand in 2021 that will target the Rolls-Royce Cullinan.
Full production of the DBX is to start in early 2020 in a new plant in St. Athan, Wales. Aston first showed the DBX concept in 2015.
