This is the new Aston Martin
DB11, hailed by its maker
as “the most powerful,
efficient and dynamically
gifted DB model” in the firm’s
103year
history. The first
product from Aston’s ‘second
century’ expansion plan, the
DB11 features a new engine
and body structure, fresh
styling, improved packaging
and motorsportderived
aerodynamic features.
Following its public unveiling
at this week’s Geneva motor
show, the frontengined,
rearwheeldrive
grand tourer can
be ordered now, priced from
£154,900.
NEW V12 ENGINE
Perhaps the standout
feature
in this most significant of new
Astons is located under the
onepiece
clamshell bonnet.
Designed and built inhouse
by
a team led by chief powertrain
engineer Brian Fitzsimons,
the new twinturbocharged
5204cc V12 is the most
powerful unit yet fitted to a
DB road car. Its 600bhp and
516lb ft outputs are sufficient
to accelerate the DB11 from
zero to 62mph in 3.9sec and on
to a top speed of 200mph. It’s
also the first seriesproduction
Aston Martin to use a twinturbo
unit. The DB11 doesn’t
have a synthesised system to
augment the engine noise
The new engine sends its
power to the DB11’s rear axle via
a ZF eightspeed
paddleshift
torqueconverter
automatic
gearbox. The car features
a mechanical limitedslip
differential with active torque
vectoring, the latter a being
first for Aston Martin
Aston hasn’t revealed official
figures, but it is targeting a
20% improvement in fuel
efficiency and CO2 emissions
over the DB9. That should
equate to combined economy
of about 24mpg and CO2
emissions of roughly 270g/km.
Key to that dramatic
improvement is a host of
technology including variable
valve timing, stopstart
and
intelligent bank activation,
which shuts down six cylinders
during periods of light
throttle usage.
STRUCTURE
Aston set its engineering
team the target of creating
a body structure that is
lighter, stronger and more
spaceefficient
than the one
that underpins the DB11’s
predecessor, the DB9. Using a
mix of new bonded aluminium
pressings, extrusions and
castings, the structure “sets
new standards for mass
versus stiffness”.
The new DB11 is longer, wider
and lower than the DB9, at
4739mm long, 2060mm wide
and 1279mm tall. Additionally,
the wheelbase is 65mm longer,
with Aston emphasising the
car’s capabilities as a true 2+2
grand tourer.
Compared with the DB9,
the front and rear track widths
have increased by 75mm and
43mm respectively, and overall
width has been extended by
28mm. The front overhang has
been reduced by 16mm and
the rear overhang increased
by 11mm, with an overall gain in
length of 50mm. By making the
wheelbase 65mm longer than
that of the DB9, Aston has been
able to mount the V12 further
back in the chassis to improve
weight distribution to 51% front
and 49% rear.
The body panels are
made from a mix of pressed
aluminium (for the clamshell
bonnet, roof and doors),
composite material (the rear
haunches, front wings and
rear decklid assembly) and
injectionmoulded
plastic (the
front and rear bumpers, sills,
front splitter and rear diffuser).
DYNAMICS
The new car’s chassis,
suspension, steering and
electronics have been
completely reworked under
the watch of exLotus
handling
guru Matt Becker, now Aston’s
chief of vehicle attribute
engineering.
Aston’s target was to give
the DB11 a broad range of
capabilities. Using a steering
wheelmounted
button,
the driver can select from
three dynamic modes — GT,
Sport and Sport Plus — which
progressively intensify the
responses of the engine,
transmission, electric power
steering and torque vectoring
by braking system. A separate
button also increases the
firmness of the Bilstein
adaptive dampers
The DB11 rides on 20in
tyres and wheels as
standard. Its Bridgestone tyres
have a bespoke tread pattern,
construction and compound.
Electric powerassisted
steering has been incorporated
to offer greater scope for
tuning and improvements in
fuel efficiency.
AERODYNAMICS
The DB11 features two
aerodynamic devices inspired
by Aston’s racing cars and also
integrated onto the trackonly
Vulcan supercar
The first of these, named
‘Curlicue’, is a gilllike
vent
incorporated into each front
wheel arch lining to reduce
frontend
aerodynamic lift. It
vents highpressure
air from
the top of each front wheel arch
through recessed apertures
behind the side strakes.
Additional highpressure
air
is extracted from the back
of each wheel arch through
stirrup vents positioned aft of
the front wheels.
The second feature, which
Aston calls ‘AeroBlade’, uses
ducted highspeed
airflow
to act as a virtual spoiler and
enhance rear stability
Intake slots incorporated in
the base of the car’s Cpillars
are fed with highspeed
air,
which then passes within the
bodywork through specially
contoured ducting before
venting via slots in the rear
deck. This highpressure
jet of disrupted air reduces
aerodynamic lift, obviating
the need for an upswept ‘flip’
in the tail to be designed into
the car’s rear.
At higher speeds, a small
active spoiler automatically
deploys from the rear deck,
increasing the effectiveness of
the AeroBlade with a negligible
increase in drag.
DESIGN
Although Aston Martin’s new
design language was previewed
on the DB10, which was created
for the Bond film Spectre last
year, the DB11 marks the first
time that it has appeared on
a full production model. The
new look was created by
Aston Martin’s design team
led by chief creative officer
Marek Reichman
Highlights include a bigger,
bolder interpretation of Aston’s
iconic grille and the pressed
aluminium, forwardhinging
clamshell bonnet, shrinkwrapped
to the engine bay.
The allLED
headlights and
taillights
are another defining
element of the DB11’s design.
They incorporate daytime
running lights and lowspeed
cornering lights for the first
time on an Aston Martin.
A roof strake that flows in an
unbroken arc from the Apillar
to the Cpillar
is another design
signature, and the side strake
on the car’s flanks, while
harking back to past Aston
Martins, has been reimagined
and now forms part of the
Curlicue air vent.
INTERIOR
The cabin is a blend of
recognisable Aston Martin
design, such as the centre
console that flows from the
dashboard to the transmission
tunnel and the familiar
gearchange buttons, and new
technology, including some
sourced from Daimler
A new instrument cluster
features a fullcolour
12.0in
TFT LCD screen, and a second,
centrally mounted 8.0in
TFT screen is dedicated to
infotainment. Operation is via a
rotary control, and an optional
touchpad offers character
recognition, multitouch
and
gesture support.
The DB11 offers more
occupant space and comfort
than the outgoing DB9.
Redesigned Apillar
structures
and a reduction in the height
and width of the sill sections
mean the door apertures are
larger, making it easier to
get into and out of the car.
Front seat occupants benefit
from a 10mm increase in
head room and a greater
range of seat movement.
Meanwhile in the rear, there’s
a 54mm increase head room
and an 87mm gain in leg room,
with the aim of making the
DB11’s rear cabin more usable
than that of the DB9
There’s also more luggage
space, with the DB11’s 270litre
boot offering a 20% increase in
capacity over that of the DB9.
Other features new to the
DB11 include keyless entry/
keyless start, parking control
including parallel and bay park
assistance, a 360deg bird’seye
camera and an electrically
powered steering column with
an ‘up and away’ function for
easier ingress and egress. by MATT BURT
