The final production form of the Middle East-only Aston Martin Lagonda sedan has been uncovered by the British sports car specialist.

With previews being provided by Aston Martin and its partners during the development process, no-one should be too surprised about the look of the 21st century Lagonda.

The exterior hardly differs from the prototype vehicle that was shown off earlier by both Oman Air and Aston Martin during hot weather testing in the desert.

The architecture of the Lagonda's interior is pretty much taken straight from the Rapide, although, thanks to the Lagonda's flatter roof line and longer wheelbase, passengers in the two rear seats should have significantly more head and leg room.

To make the innards more appealing for the super-wealthy clientele that Aston Martin is aiming for with this car, the company's bespoke Q division has been called in to apply generous lashings of diamond-quilted leather, amongst other upgrades.

Aston Martin Lagonda - original and new

Aston Martin has yet to fully detail the car's mechanical package, but it's known that the Lagonda is based on the company's VH architecture.

The five-door 2015 Rapide S, which also rides on the same underpinnings, features a 5.9-litre V12 pumping out 412kW of power and 630Nm of torque to the rear wheels via an eight-speed automatic transmission. The Rapide S has a claimed 0-100km/h time of 4.4 seconds.

Reports indicate that the Lagonda sedan can hit speeds of more than 280km/h.

According to Autocar, the Lagonda wears a suit made from carbon fibre-reinforced plastic and is a much larger beast than the Rapide S that it's closely related to.

With a body that stretches out over almost 5.4 metres and sitting on a 3.19m wheelbase, the Lagonda is 378mm longer end-to-end than the Rapide S and features an extra 199mm between the wheels. Unlike the Rapide, the Lagonda is a true sedan, with a flip-up boot lid.
