الموضوع: Aaston Martin Vanquish S

The fastest road car in the history of Aston Martin. A car that fuses hand-crafted tradition with the highest calibre of automotive technology. Appropriately it is our flagship car - the Vanquish S - the ultimate Aston Martin.





Aston Martin’s hand-built 6.0-litre V12 is renowned as one of the finest engines in the world: enormously powerful, smooth and beautiful. It can also lay claim to being the world’s best-sounding high performance car engine. In the Vanquish S, it reaches its zenith. Maximum power is 520 bhp (388 kW) at 7000 rpm, with maximum torque of 425 lb ft (577 Nm) at 5800 rpm.

Such power delivers sterling performance. Indeed, this is the fastest-ever road going Aston Martin. Top speed is more than 200 mph (321 km/h), the 0-62 mph (100 km/h) dash is accomplished in only 4.8 seconds while 0-100 mph (160 km/h) takes just 9.8 seconds. But it is the mid-range acceleration that is truly sensational; 50-70 mph (80-112 km/h) takes only 6.5 seconds in sixth gear. Overtaking is effortless




Despite the high-technology specifications, the Vanquish S is built in the same manner as other Aston Martins before it, one at a time, by hand. An individual craftsman takes responsibility for the creation of every car.

In preparation for production of the Vanquish, the factory at Newport Pagnell in Buckinghamshire, England, received a multi-million-pound refurbishment that included an all-new assembly line, paint shop, rolling road and water test facility, which simulates monsoon conditions to ensure a watertight interior. Today, technicians who used to hold old-fashioned welding guns now wield dual-feed adhesive guns to bond together composite components, crash structures and aluminium panels.












The Vanquish S has one of the most advanced construction techniques of any road car, using composite materials and processes familiar to the aerospace business but rarely seen in the motor industry.

Each car starts as a heat-cured aluminium bonded monocoque, known as the ‘tub’, which uses a combination of extruded and folded aluminium panels that are bonded and then riveted together. The tub is bonded to a nine-layer carbon fibre tunnel, which gives the Vanquish S an extremely rigid yet lightweight backbone.

The benefit of a carbon fibre tunnel over aluminium is its high strength-to-weight ratio. To provide the same levels of strength and rigidity, an aluminium tunnel would be approximately twice as heavy.







The Vanquish S is full of technological innovation, designed to improve strength and safety. The advanced aluminium and carbon fibre body is replete with world firsts. One example is the specially developed braided carbon-fibre used for the ‘A’ posts and the engine bay cross brace. Engineers from Aston Martin invented a novel braiding process that encases a polyurethane foam core with triaxial carbon fibre. The result is an immensely strong yet light structure capable of withstanding the force of a crash or rollover.

Passive safety is only part of the equation. Equally vital in any car, and especially one with the performance of this Aston Martin, is dynamic safety. The Vanquish S epitomises this with superbly responsive handling, giving the driver every chance to avoid any dangerous obstacle or situation.
