Nuevo Aston Martin Vantage V8

  • Vantage V8 con un propulsor 35 cv más potente
  • Incremento de potencia de 20 cv en el DB9
  • Mayor equipamiento disponible

Aston Martin ha presentado hoy la renovación de los dos principales modelos de su gama, excluyendo al reciente DBS. Comenzando con el Vantage V8, éste ha recibido importantes mejoras en el apartado mecánico, pasando a incorporar un propulsor de 4,7 litros de cilindrada que entrega 420 cv y 470 Nm de par máximo, hasta ahora equipaba una mecánica de 4.3 litros que entregaba 385 cv y 412 Nm. Lo más sorprendente es que pese al aumento de potencia su consumo se ha reducido en más de un 10%.

En el caso del Aston Martin DB9 las diferencias no son tan notables, puesto que la ganancia de potencia es menor que en su hermano pequeño. El DB9 mantiene su propulsor V12 de 6 litros, pero incrementa su potencia hasta alcanzar los 470 cv (20 cv más) y su par máximo se sitúa en unos impresionantes 600 Nm. Importantes mejoras, por tanto, para ambos modelos, pero la lista de cambios no termina aquí, ni mucho menos.

En ambos modelos se han revisado las suspensiones a fondo para lograr un mejor comportamiento a la par que se mantienen los niveles de confort deseables en cualquier Aston. En el caso del Vantage V8 los cambios se han orientado en mejorar la maniobrabilidad del deportivo, mientras que en el DB9 se han introducido unos amortiguadores Bilstein y unos refuerzos que aumentan un 10% la rigidez torsional del bastidor.

El cambio ha sido otro de los apartados que recibe mejoras significativas en ambos modelos. En el caso del Vantage V8 se han optimizado tanto el cambio manual de 6 velocidades como el secuencial Sportshift, incluyendo un nuevo embrague y volante de inercia, reduciendo el peso de estas piezas sometidas a rotación y por tanto mejorando la respuesta del motor.

En el caso del Vantage V8 con el cambio Sportshift también se ha mejorado su gestión para mejorar el rendimiento, y ahora incluye una opción que detecta cuándo se está negociando una curva o bajando un puerto, manteniendo la marcha insertada y preparando la inferior por si el conductor decide insertarla, maximizando así la acción del freno motor.

Entre el equipamiento opcional disponible para el Vantage V8 se incluyen nuevas e interesantes opciones, como una nueva gama de llantas de aleación ligera, un paquete deportivo que incluye un tarado más duro de la suspensión y la adopción de muelles Bilstein -entre otras mejoras-, acabado interior en zinc con terminación en grafito plateado o el sistema de navegación GPS con disco duro integrado y conexión iPod y auxiliar, que se ofrece de serie.

Ésta es la extensa nota de prensa facilitada por Aston Martin acerca de la presentación de la nueva gama del Vantage V8.

Technical Enhancements for Aston Martin V8 Vantage

Gaydon, 23 May 2008. Aston Martin’s V8 Vantage – originally launched to widespread critical acclaim at the Geneva Motor Show in 2005 – is to receive significant technical enhancements, reaffirming the car’s position as one of the world’s most desirable and exhilarating sports cars.

While the universally distinctive and award-winning shape of the V8 Vantage is retained, the car benefits from a number of technical changes which include significantly up-rated engine performance from a new 4.7 litre power unit in both Coupe and Roadster variants. Other changes include revised dynamics to take full advantage of increased power and torque availability, improved Sportshift™ transmission software and a new sports suspension option.

The 4.7 litre V8 engine has a power output of 420bhp (an 11% increase on the previous 4.3 litre unit) and delivers peak torque of 470Nm (15% increase), providing the V8 Vantage with new reserves of mid-range performance, an improved 0-60mph time of 4.7 seconds and top speed of 180mph (288km/h). Combined European fuel economy and CO2 emissions are also improved by 13% (Sportshift™).

Inside, the changes include a new centre console and revised switchgear and the introduction of an ECU replacing the previous V8 Vantage key. Externally, the acclaimed V8 Vantage design appearance is enhanced with a range of new standard and optional 19’’ alloy wheels.

Aston Martin Chief Executive Officer, Dr Ulrich Bez said: “Continued development and evolution of our unique VH (Vertical-Horizontal) architecture has brought even higher levels of refinement and dynamic performance to our whole range.

“With the new 4.7 litre engine and associated changes we have taken the V8 Vantage to new levels of performance to produce an even more desirable sports car.

“The V8 Vantage is now the most successful Aston Martin in our history and we are confident these changes will continue its appeal and driving enjoyment for both new and existing customers.”

Engine

Improvements in performance have been achieved through a number of carefully developed changes to Aston Martin’s acclaimed V8 engine.

The cylinder bore and stroke has been increased from 89mm to 91mm and 86mm to 91mm respectively, giving a total displacement of 4735cc.

The increase in cylinder bore is facilitated by a move to cylinder liners that are pressed into the pre-machined aluminium alloy block, allowing a thinner liner than was possible with the cast-in design of the 4.3 litre engine.

The new forged steel crankshaft provides the 91mm stroke and incorporates new holes in the counter weights for reduced rotating mass and improved inter-bay breathing. New forged steel con-rods and cast aluminium pistons complete the capacity-related changes.

Other key changes include efficiency improvements to the dry sump lubrication system, including a new sump casting with oil pick-up points moved from the front and rear to the sides of the sump. The cylinder heads are modified with a new intake port and an inlet valve size increase from 34.9mm to 35.9mm. The intake manifold has been modified to match the new port to optimise air flow.

Transmission

The V8 Vantage transmissions have also undergone changes to improve performance and to handle the increased levels of power and torque. Both the standard manual stick-shift gearbox and the optional Sportshift™ transmission benefit from a modified clutch and flywheel, reducing clutch pedal efforts and delivering a 0.5kg weight saving, reducing the rotating masses within the powertrain, and hence increasing engine responsiveness.

Aston Martin’s Sportshift™ transmission has undergone a series of specific changes to broaden the capabilities of the gearbox to offer customers enhanced comfort and convenience with sporting capabilities. Changes include a revised control strategy, allowing the transmission, rather than the engine, to dictate how best the engine torque should be deployed to optimise performance and deliver power smoothly and consistently.

‘Dual Throttle Map’ software is also featured. When ‘Comfort’ mode is selected the engine reacts in a smoother more progressive manner to driver throttle inputs and in the default ‘Sports’ mode the throttle mapping is more aggressive, delivering a more dynamic and sporting feel.

Sportshift™ now also has the capability to take inputs from the steering wheel enabling the current gear to be held when the car is negotiating a corner and hill descent detection, allowing a low gear to be held, maximising the effects of engine braking.

Suspension A series of improvements are introduced to the V8 Vantage chassis and suspension setup to deliver improved body control and low speed ride quality; enabling the driver to take full advantage of the increased performance potential.

A number of the improved components originally introduced on the Vantage Roadster are now carried over to the Coupe, including revised upper damper mountings and bump stops. Additionally, the front spring rates are stiffened by 11% at the front and 5% at the rear.

Steering geometry is also modified to improve steering feel, while the front lower suspension arm compliance bushes are stiffened by 22% to provide enhanced steering response and handling.

The V8 Vantage also now benefits from Bilstein dampers as standard; these low-friction dampers provide improved levels of dynamic capabilities and further improve ride quality.

Design & Optional Equipment

Also introduced as an option for both Coupe and Roadster variants is a new Sports Pack which comprises forged lightweight alloy wheels aiding a lower unsprung mass, re-tuned Bilstein dampers with improved dynamic response, up-rated springs and a revised rear anti-roll bar (Coupe only). The Sports Pack is intended to offer greater agility, high speed body control and precision feel for the most enthusiastic of drivers.

Although the award-winning exterior design of the V8 Vantage remains largely unchanged, a new 20-spoke 19’’ alloy wheel is introduced as standard, with either diamond turned silver or graphite finishes available as options, affording customers maximum choice. Alternatively, as part of the Sports Pack option, a 5-spoke lightweight aluminium wheel will be provided.

In the cabin, a new centre console constructed from die cast zinc alloy with a graphite silver finish is introduced along with a new ECU – first seen on the DBS in 2007. The ECU – constructed from glass, polished stainless steel and polycarbonate – replaces the key used previously for the V8 Vantage. The revised car also includes a new Hard Disk Drive (HDD) Navigation System offering faster route processing, additional features and improved graphics. Full ipod/MP3 integration is retained as standard equipment.

First shown as a concept car at the 2003 North American International Auto Show in Detroit, the V8 Vantage caused a worldwide sensation as it allowed Aston Martin to enter a new sector of the premium sports car market with a genuine alternative to other cars on offer. Deliveries of the V8 Vantage Coupe to customers began in late 2005, joined by a convertible sibling in 2007 when the Vantage Roadster was launched. The car is hand built at Aston Martin’s Headquarters at Gaydon, Warwickshire, UK and to date more than 10,000 have been delivered to customers around the world.

Prices for the revised V8 Vantage will be confirmed at a later date, with deliveries set to commence from quarter three 2008.

A continuación tienes la nota de prensa sobre la presentación de la nueva gama del Aston Martin DB9.

Aston Martin introduced a revised version of the company’s critically acclaimed DB9 at the 2008 Geneva Motor Show, which includes significant enhancements to standard specification.

These changes include a revised version of Aston Martin’s 6.0 litre V12 engine to deliver improved power and torque. Peak power of 470bhp (350kW) – increased by 20bhp (30Nm) – is now reached at 6,000rpm, resulting in a power to weight ratio of 267bhp per tonne (199kW/tonne) – an increase of 11bhp per tonne over the existing Aston Martin DB9.

Peak torque of 600Nm is delivered at 5,000rpm, providing even more accessible power for the driver, as well a greater performance feel overall. Accordingly, top speed is now 190mph (306km/h) and the benchmark 0-60mph time improves by 0.3 seconds for the Touchtronic transmission – which benefits from a new valve box and integrated transmission controls to achieve quicker gear shifts – to 4.6 seconds and by 0.1 seconds to 4.6 seconds for the manual gearbox.

The latest Aston Martin DB9 also incorporates a series of chassis developments for both the Coupe and Volante derivates. Bilstein dampers are introduced in addition to revised upper suspension arms and retuned suspension bushes to deliver improved ride quality; aiding greater refinement in the Volante and an enhanced sporting feel in the Coupe. The Aston Martin DB9 Volante also benefits from revisions to the front shear panel which increases torsional rigidity by 10%, further improving refinement.

The Aston Martin DB9 manages to combine all facets of style, quality and usability of a traditional Aston Martin without relying on retrospective detail or design. Accordingly, styling changes to the revised Aston Martin DB9 are subtle, reflecting the car’s timeless design and understated elegance.

Exterior styling changes include the introduction of a new standard 19” 10-spoke alloy wheel, new door mirrors and a revised anodised aluminium five-bar grille. In the cabin changes include a new centre console constructed from die cast zinc with a painted iridium silver finish and the introduction of a new Emotion Control Unit (ECU) – first seen on the DBS in 2007. The ECU – constructed from glass, polished stainless steel and polycarbonate – replaces the key used previously for the DB9.

The innovative Aston Martin DB9 introduced an exciting new era for Aston Martin. The 2+2 sports car set new standards in its class due to its astonishing combination of technology, agility and design. The car marked the beginning of a new era for Aston Martin and became the first car to be hand-made at the company’s state-of-the-art facility in Gaydon, Warwickshire.

Sales of the Aston Martin DB9 started in spring 2004, and to date, more than 10,000 examples have been produced and delivered to customers around the world – surpassing the DB7 as the most successful Aston Martin of all time.

Deliveries of the updated Aston Martin DB9 begin during quarter two 2008, with prices from £113,950 for the DB9 Coupe and £122,950 for the DB9 Volante.
