Aston Martin DB9

The Aston Martin DB9 coupe is one of four seats (2 +2), built with lightweight materials (predominantly aluminum) and a twelve-cylinder engine in 'V' and 456 hp. It is available with manual or automatic and a convertible version, called the DB9 Volante. The manual is DB9 with € 172,062, the DB9 Volante, € 187,870. The automatic has a surcharge of € 4608

In the outer edges have been prevented and that various elements protruding from the body (the bumpers are not distinguished from the silhouette). Despite this, the value of the aerodynamic coefficient is not good: 0.35. A Porsche 911 is 0.28, a Bentley Continental GT Lamborghini Murcielago 0.32 and 0.33, according to Aston Martin has not sought a rate but a low stability at high speed.

The doors open normally, but tilts up 12 °. The hands are illuminated by external LEDs, and also these LEDs are used in the pilots.

Take 19 wheels and tires are Bridgestone REO 50, specific to this model (235/40 ZR19 front and 275/35 ZR19 rear). The brake discs are ventilated and striated. It has ABS, electronic distributor and brake assist , stability control, front and side airbags and seatbelt pretensioners on.

The engine is a twelve-cylinder 'V' to 60 º. Gives 456 hp at 6,000 rpm and 570 Nm of torque at 5,000 rpm. It is based on carrying the Vanquish, but change the crankshaft, the intake and exhaust manifolds, the lubrication system and the electronic management. Cylinder head, 48 valves, was developed jointly by Aston Martin and the department of development and technology from Ford. You can lead a gearbox 'Graziano' manual or a "ZF" automatic, two of six relationships. With this engine, the DB9 reaches 300 km / h and accelerates from 0 to 100 km / h in 4.9 s (5.1 s automatic).

For the interior door handles, dashboard, instrument panel and some of the indicators used aluminum. The wood has been used in only two places: the top of the console, and if the buyer so wishes, at the top of the door panel. There are twenty different colors of leather upholstery for the interior.

The counter has the peculiarity that rotates in the opposite direction to clockwise (image), as in Atom and the DB2. There is but a red light that illuminates to warn that it has reached the limits of the regime. The time at which turn depends on the ambient temperature, the time it takes the engine running and the same mileage.

In the box there is a screen-type OEL (organic electroluminescent display), the DB9 is today the only production model that carries a serial. Regarding an LCD has higher resolution, contrast and viewing angle.

No shift in the automatic version. In the dashboard there are four buttons to select the operating mode (P, R, N, D) and magnesium cam behind the wheel to change the relationship. The four buttons change is the starting motor, which is crystal clear (picture). When pressed red lights, and then turn blue.

The stereo (Linn Hi Fi system) has 10 speakers (950 W) and a bass (200 W) which incorporates an accelerometer to compensate for pressure changes in the internal wiring is optical fiber.

It has the aluminum chassis, with parts made by processes of melting, extrusion or stamping, the bonnet, roof and rear wings are also of this material. The front wings and boot lid are of a compound.

The suspension is independent double parallelogram deformable triangle. Both the front and rear are mounted on a subchasis; also supports the rear of the gearbox and differential. The two subchasis and the body of the pads are made of aluminum. The DB9 weighs 1785 kg (manual version), the same as a BMW M6, a Bentley Continental GT weighs 600 kg (2,385 kg).

The pieces of the chassis and body panels are connected by an adhesive. To join the rear pillar is used an ultrasound system that vibrate (at a frequency of 20,000 Hz) the molecules of the two pieces of aluminum to merge, creating a link between the two pieces. Such a union is 90 percent stronger than a welding points.

To achieve an optimal weight distribution (50:50) and to lighten up the set have been used other lightweight materials such as magnesium (in the interior structure of the doors and the steering column) or the carbon fiber transmission shaft that connects the motor (located at the front) with the gear lever (located behind).

The Aston Martin DB9 is manufactured by hand at the Gaydon, Warwickshire.
