The iconic Aston Martin side strake, a design feature of every DB car since the DB4, has been redesigned for the DBS, incorporating a side repeater formed by a bank of LEDs. Improved aerodynamics shape the rear of the DBS, where the more prominent boot spoiler is carefully incorporated into the carbon-fibre boot lid. A horizontal chrome finisher is set into the lid to accentuate the wide track of the new car. The car's flat undertray helps to improve the aerodynamics of the underbody surface and culminates in a new carbon-fibre rear diffuser, another feature carried over from the race cars. This device creates an area of low pressure beneath the rear of the car, reducing lift and improving high-speed stability without the need for large, unsightly external spoilers. The new one-piece diffuser also incorporates the DBS's large and distinctive twin exhaust tailpipes.
The interior of the DBS represents the epitome of Aston Martin's commitment to using materials honestly, without disguise or embellishment. Lightweight materials are used throughout to save weight; door pulls are made from carbon-fibre, for example, and the carpet has been woven with lighter fibres to save valuable kilograms. Special semianiline leather is used throughout the cabin, saving weight as well as giving a soft feel and distinctive aroma.
