Aston Martin has confirmed that design work on the production-spec DBX has been completed, Autocar reports. Company chief executive Andy Palmer says the finished vehicle maintains many of the key design elements of the concept but that unlike the show car, it has four doors rather than two.

Earlier this month, Autobild indicated that the DBX would follow in the footsteps of the Valkyrie hypercar by utilizing cameras instead of traditional wing mirrors. While Aston Martin has yet to confirm or deny these reports, ditching mirrors would allow company designers to remain true to the original concept and potentially pave the way for a full range of mirrorless Astons.

When the DBX launches in 2019, it will initially be sold with both the company’s 4.0-liter twin-turbo V8 with 503 hp and 513 lb-ft of torque and the range-topping twin-turbo 5.2-liter V12 with 600 hp and 516 lb-ft.
