The Revolution in Design and Aerodynamics
Under the leadership of Marek Reichman, Aston Martin's design team faced the challenge of evolving
the
brand's classic visual language without falling into the "retro design" trap. The goal was to
create a Grand
Tourer (GT) that respected the golden ratio of 1:3 between the glass area and the bodywork, but
that
introduced futuristic and functional elements.
The Engineering of the "Clamshell" Hood
One of the most distinctive and technically complex features of the DB11 is its clamshell hood.
It is a single piece of pressed aluminum that extends across the entire front of the vehicle.
This design decision eliminated the unsightly cut lines (panel gap seams) that
normally cross the hood and fenders on conventional cars.
Besides aesthetic purity, the clamshell hood serves a safety purpose. Due to its large area and
deformation capacity, it is exceptionally effective at dissipating energy in the event of an
impact with
pedestrians. This allowed engineers to dispense with heavy and complex pyrotechnic systems that
raise the hood in collisions, saving weight and space in the engine compartment. The hood's
opening,
hinged at the front, is a direct homage to brand classics, such as the 1950s DB2, offering
a theatrical view of the V12 or V8 engine.
Patented Aerodynamic Innovations
The DB11 broke with the tradition of using large rear aerofoils or spoilers that could compromise the
elegant silhouette of a GT. Instead of using visible solutions, the engineering team integrated
aerodynamics within the bodywork through two main innovations: the Curlicue and the AeroBlade.

| Curlicue |
Front fenders |
A molded air vent inside the wheel arch that extracts the turbulent
high-pressure air
generated by the spinning wheels. This reduces lift on the front
axle and smooths the
airflow along the sides of the car. |
| AeroBlade |
C-Pillars and Trunk Lid |
Air is captured by discreet intakes at the base of the rear pillars
(C-pillars),
channeled through internal ducts in the bodywork, and expelled
vertically through a slot in the
trunk lid. This jet of air creates a "virtual spoiler", pushing
the rear down
without the need for a physical wing. |
The AeroBlade system is complemented by a small active spoiler (Gurney flap) that rises automatically
at very high speeds to increase the effectiveness of the air jet, ensuring stability without
penalizing the
drag coefficient at cruising speeds.
Structure and Chassis: The New Aluminum Platform
The DB11 debuted an entirely new bonded and riveted aluminum architecture. Unlike the previous VH
platform, this new structure was optimized to be lighter, stiffer, and more efficient in terms
of
internal space utilization.
The construction uses a combination of extruded aluminum for the main side members and complex
castings
for the suspension mounting points, ensuring superior torsional rigidity. The doors are
manufactured in
magnesium, an exotic material choice that reduces weight in a critical area and makes closing
easier with
a premium feeling of solidity.
The suspension adopts a double wishbone configuration at the front and a multi-link system
at the rear. Dynamic behavior is managed by adaptive Bilstein dampers, which
offer three distinct modes selectable by the driver: GT, Sport, and Sport Plus. These modes
alter not
only the damping stiffness, but also the throttle response, gear shift speed, and
the weight of the electric power-assisted steering (EPAS) — the first time an Aston Martin DB
used
electric steering.
