Aston Martin DB9 Volante

The new Aston Martin DB9 is one of the most sophisticated 2+2 sports cars available in the world today.

The Aston Martin engineers' goal was to make a beautiful, distinctive car that was also outstandingly nimble and fast, and a car that was a worthy successor to the DB7 - the best selling Aston Martin in history.

In every case, technology is used to make the car better and to make the driving experience more enjoyable. In most cases, the technology is invisible, always there, always helpful, never intrusive.

Light and immensely strong aluminium frame

In a long list of technological innovations, the most important is the bonded aluminium frame. Aston Martin believes it is the most structurally efficient body frame in the car industry. The new Aston Martin VH (vertical horizontal) aluminium structure gives immense benefits. It is very light, aiding performance, handling, economy and durability. It is also enormously strong. Despite being 25 per cent lighter than the DB7 bodyshell, the DB9 structure has more than double the torsional rigidity.

This is the car's backbone, the skeleton to which all the mechanical components are either directly or indirectly mounted. Drawing on the experience and technology pioneered in the Vanquish, the DB9's frame is made entirely from aluminium. Die-cast, extruded and stamped aluminium components are bonded using immensely strong adhesives, supplemented by mechanical fixing using self-piercing rivets.

"It is far superior to the conventional steel saloon-based floorpan often used by high-value brands," says Aston Martin DB9 Chief Programme Engineer David King.

"The torsional rigidity of a car is a key factor in driving enjoyment and good handling. Any flexibility of the body compromises the performance of the suspension, delays vehicle response and corrupts feedback to the driver."

The tub is made in aluminium and the body panels are then fitted, again using adhesives, in the advanced body assembly area at Aston Martin's new Gaydon facility. This adhesive is applied by a robot - the only one at Aston Martin. Computer controlled hot-air curing ensures the highest standards of accuracy and repeatability.
