Aston Martin V12 Vantage S Roadster

2014-07-21 Read: 342x

Aston Martin is opening up a new world of exhilarating driving excitement with the announcement of the hotly anticipated V12 Vantage S Roadster.

When it arrives in markets around the world later this year the new sports car will become the luxury British marque's most potent, fastest and fastest-accelerating series production roadster to date and follows in the broad tyre tracks of the V12 Vantage S Coupe that was launched to worldwide acclaim in 2013.

Providing the most visceral yet engaging open-top experience in Aston Martin's current range, the new V12 Vantage S Roadster delivers characteristic sporting agility underpinned by an enviable sports 'soundtrack' generated by its naturally aspirated V12 engine and expertly-tuned sports exhaust.

Equipped with the latest 565 bhp (573 PS) Aston Martin AM28 6.0-litre V12 engine, featuring state-of-the-art Bosch engine management, the car is capable of reaching 201 mph and sprinting from rest to 60 mph in only 3.9 seconds (0-100km/h 4.1 seconds).

Peak and low rev torque is delivered in abundance. With 620 Nm available at 5,750 rpm the V12 Vantage S Roadster is not to be found wanting in this vital department. Crucially, too, low rev torque - measured from just 1,000 rpm - starts at a colossal 510 Nm. Together, these statistics demonstrate the Aston Martin engineers' ability to create a 'flatter', yet 'fatter', torque curve which supports exceptional driveability and strong pick-up through the gears.

Aston Martin Director of Design, Marek Reichman, said: "The V12 Vantage S Roadster is the mechanical embodiment of our company's exceptional spirit.

"Beautiful, powerful and spirited it is as spectacular to listen to as it is to look at. The new roadster is truly a treat for the senses with, underlying all this, the capacity to deliver one of the most dynamic, exciting and stirring driving experiences in our current range.

"I'm sure the V12 Vantage S Roadster will appeal to luxury sports car enthusiasts worldwide who want to add a truly exceptional new model to their garage."

As with its coupe sibling, race car technology runs right through the DNA of the V12 Vantage S Roadster with, for instance, CNC machined combustion chambers and hollow camshafts just two examples of track technology feeding through to the road.

Another clear example is the new car's SportshiftIII 7-speed transmission. Engineered to exploit the full sporting potential of the V12 engine, the latest generation SportshiftIII hydraulically actuated automated manual transmission provides motorsport-style paddle shift changes for optimum performance delivery. The unit, which replaces the six-speed manual gearbox found in the previous V12 Vantage Roadster, is also appreciably lighter - saving 20 kg versus its forebear.

This race-derived and motorsport-proven technology - used routinely in Aston Martin Racing's race-winning Vantage GT4, GT3 and GTE competition cars - provides for great driver control with only milliseconds of torque interruption and delivers precise and swift gear changes.

The SportshiftIII transaxle, developed in conjunction with transmission experts Oerlikon Graziano, joins an extensive array of new sport and track-focused developments that ensure the V12 Vantage S Roadster is fully equipped to exploit the huge performance potential of its 6.0-litre naturally aspirated engine.

The use of three-stage adaptive damping, allied to three-stage DSC and two-stage ABS, allows the driver to more precisely tailor the car's dynamic character. 'Normal', 'Sport' and 'Track' modes provide a broad swathe of dynamic performance that can be tuned to better suit the driver's requirements. The system also governs the level of power steering assistance offered.

Working alongside the extended chassis capabilities is a 'Sport' mode, controlled via a button on the centre console, that alters throttle response, gearshift speed and timing, and exhaust note to, once again, tune the character of the car to the driver's requirements.

Optimum braking performance is delivered via the specially-created carbon ceramic discs all round, with near-identical brakes appearing on the brand's ultimate GT, the Vanquish. Meanwhile a whole new lightweight exhaust system - derived from that of Aston Martin's most expensive and exclusive production model, the One-77 hypercar - is wonderfully sonorous.

The ZF Servotronic power assisted steering offers a quick, slick, 15:1 ratio and,  linked to the adaptive damping button, provides two-mode steering assistance designed to best match the 'Sport' or 'Normal' settings generated by the Adaptive Damping System.

As Aston Martin's most overtly sporting convertible, with an even more dynamic character than the luxurious Vanquish Volante ultimate GT or refined DB9 Volante, the V12 Vantage S Roadster has been styled to reflect is position as the flagship convertible in the Vantage family.

In keeping with the V12 Vantage S Coupe, the Roadster replaces the famous aluminium vanes in the Aston Martin grille - with a carbon fibre arrangement that also includes sporty black or titanium silver mesh. Created to maximise airflow to the V12 engine, the new grille is inspired by both the remarkable CC100 Speedster Concept and the Vantage race cars.

Other distinguishing features of the V12 Vantage S Roadster include the option of lightweight forged alloy ten-spoke wheels.

The new Roadster retains the same compact proportions of its predecessor while features such as the pronounced bonnet louvres, optional bold graphics (painted carbon front grille, front grille lipstick and tailgate panel) as well as the exterior carbon pack and flared wheel arches underscore its sporting abilities.

Inside, as out, the new car has been styled to reflect its powerful nature. New-style seat trim and door trims, with Sport and carbon fibre lightweight seat options - present V12 Vantage S Roadster buyers with an exciting array of choices.

The optional Interior Carbon Pack, which adds carbon fibre to the car's facia and door pulls, plus the availability for the first time in a V12 Vantage S Roadster of black pedals, further enhances personalisation options for those in search of a truly bespoke sports car.

Aston Martin Vantage GT8 (2016)

The 8 denotes the number of cylinders under the bonnet. The GT12 had, you guessed it, 12 cylinders – but it also had one other large number on the spec sheet: the price. That car cost a cool £250,000, while the GT8 costs a more reasonable (but only comparatively) £165,000.

Not quite. The V8’s been massaged to produced an extra 10bhp, for a 440bhp total, and there’s 361lb ft to help haul you up ...

What It Cost Owning an Aston Martin for a Year

The day has arrived: I've sold my Aston Martin V8 Vantage. My famous bumper-to-bumper warranty companion is gone, lost to the world, and now officially owned by someone else. This means two things. First, it's time for me to total up exactly what I spent to own it. And second, the people in the Aston Martin PR department can finally break out that bottle of champagne they've been saving up.

It's not a new car. And that makes it a better car.

The crazy and the cool were never so damn good

It's the choice that dreams are made of. Before us are two cars that inspire shaky hands and moist palms.

Jaguar F-type R Coupe vs Aston Martin V12 Vantage S (2014)

From the big Healeys of the 1960s to the TVRs of the 1990s, we Brits have always known how to put together a properly exciting front-engined, rear-drive two-seater.

2009 Aston Martin V8 Vantage

Aston's least costly car is also its best.

Aston Martin’s V-8 Vantage is the company's least expensive car, but it looks a lot like its V-12–engined big brothers, the DB9 and the DBS. Although only car nerds can distinguish which current Aston is which, the Vantage's short overhangs, taut lines, and absence of gratuitous scoops and fins make it the best-looking of the bunch. Even in DBR9 racing g...

2005 Aston Martin V8 Vantage

A first drive of Aston's smallest. And finest.

Everyone agrees: Aston Martins are gorgeous. They are also expensive and fast. And usually lacking in cabin space and complete reliability. With the V-8 Vantage, which goes on sale here in January, Ford's boutique brand moves a little closer to the shopping mall. Not that far, mind, as production is limited to 3000 cars a year and the price will be a...

Aston Martin V12 ZAGATO

When you combine the brands of Aston Martin and Zagato you're setting the scene for some fairly major expectations.

Aston Martin Vantage Prodrive

Normally, when it comes to cars, it’s hard to get excited about anything as mundane as a button. But in the Prodrive Aston Martin V8 Vantage, one button in particular becomes something of an obsession.

2015 Aston Martin Vantage GT
