Aston Martin's Vantage RS Roadster Takes Aim at Porsche's 911 GT3 S/C
Aston Martin's hardcore Vantage RS is getting an open-top sibling that trades some rigidity and weight for more noise and sunshine.
Key Takeaways
- Aston Martin is developing a Vantage RS Roadster, an open-top version of its most hardcore Vantage, aimed squarely at the Porsche 911 GT3 RS.
- The Roadster inherits the coupe’s full aero package, including the massive fixed rear wing, revised nose, deeper splitter, vented front fenders, and centrally mounted quad exhaust.
- Power is expected to approach 700 hp from the Mercedes-AMG sourced 4.0-liter twin-turbo V8, up from the standard Vantage’s 656 hp and the Vantage S’s roughly 671 hp.
- The Roadster will weigh more than the coupe, but Aston Martin is targeting a gap close to Porsche’s ~83 lb difference between the 911 GT3 and GT3 RS.
- An open roof changes the aerodynamics fundamentally, so the wing’s downforce balance will differ markedly with the top up versus down.
- Expect a price near $270,000, positioning the RS Roadster as one of the most expensive drop-tops in the Vantage lineage.
What Is the Vantage RS Roadster?
The Vantage RS Roadster is Aston Martin’s open-top answer to the Porsche 911 GT3 RS, the track-bred Zuffenhausen special that has defined the hardcore naturally aspirated 911 for two decades. Where most roadsters are built as softer, slower siblings of their coupes, the RS Roadster is conceived as the opposite: a convertible that keeps the aggression of the fixed-roof RS and simply removes the roof panel.
That means the Roadster carries the same dramatically reworked nose, deeper front splitter, vented front fenders, serious rear diffuser, and four centrally mounted exhaust pipes as the coupe. The headline act, as with every modern GT car that takes itself seriously on track, is the huge fixed rear wing. On a roadster, that wing is both a statement and an engineering problem, because the roof it was designed around no longer exists.
Why Build a Roadster Version of a Track Special?
Aston Martin has spent the current Vantage generation closing the gap with Porsche, and the strategy is clearly to mirror the 911’s breadth rather than fight it with a single body style. Porsche sells the 911 GT3 as both a coupe and a roofless Speedster-style special, and the GT3 RS exists as the ultimate expression of the formula. By offering a Vantage RS in both roof configurations, Aston gives buyers who want the wing and the noise without committing to a fixed roof a reason to stay in the Gaydon camp.
There is also a commercial logic. The Vantage Roadster already commands a premium over the coupe and draws buyers who value the experience as much as the lap time. An RS version extends that desirability upward, letting Aston Martin charge flagship money for a car that shares its fundamental architecture with the $190,000-plus standard Vantage.
How the Roadster Compares to the Coupe
Weight is the central compromise. The current Vantage Roadster already gains roughly 130 lb over the coupe, a figure that lines up with Aston Martin’s own ~60 kg transformation penalty for the soft-top mechanism and the extra structural reinforcement required to keep the body stiff with the roof gone. On the RS, Aston Martin will work to shrink that gap, because a track-focused car cannot afford to carry convertible ballast unchecked.
Porsche is the reference point here. The latest 911 GT3 and the more extreme GT3 RS are separated by only about 83 lb, despite the RS carrying a hydraulic multi-element rear wing, a wider track, fatter tires, and a full aero suite. That is the number Aston Martin will be targeting: keep the Roadster close enough to the coupe that the roof feels like a choice rather than a penalty.
Even if the Roadster cannot match the coupe’s torsional rigidity or its ultimate on-limit pace, the trade may be worth it. Dropping the top trades a fraction of downforce for vastly more of the sensory payoff that sells cars like this in the first place. Most owners will never exploit the jumbo wing’s peak load, but every one of them will feel the V8 with the sky above.
The AMG V8 and the Power Question
Every current Vantage is powered by the 4.0-liter twin-turbo V8 sourced from Mercedes-AMG, the M177 unit that Aston Martin hand-assembles and tunes at Gaydon. The standard Vantage already produces 656 hp and 590 lb-ft of torque, while the newer Vantage S adds roughly 15 hp on top of that. The RS is expected to push further, with output anticipated to approach 700 hp.
That figure should be read as a target rather than a confirmed specification. Aston Martin has not published RS numbers, and the jump from 671 to 700 hp would likely come from revised turbo sizing, calibration, and exhaust tuning rather than any change to displacement. What is certain is the character: a hot-V twin-turbo V8 with a rawer, louder exhaust note than the coupe, amplified by the open cabin.
The comparison with Porsche is instructive. The 911 GT3 RS makes around 518 hp from a naturally aspirated 4.0-liter flat-six. Aston Martin wins the horsepower argument decisively, but Porsche wins the aero and chassis argument by a comparable margin. The RS Roadster is not trying to beat the GT3 RS on the scales or the stopwatch; it is trying to beat it on theater and straight-line urge while keeping the downforce conversation credible.
Aero and the Open-Roof Problem
A fixed wing on a coupe is a solved problem. A fixed wing on a roadster is not, because the roof panel it was tuned against is missing. With the top down, the airflow over the cabin changes completely, altering the pressure the wing sees and therefore the downforce it generates. With the top up, the Roadster behaves much more like the coupe.
Aston Martin’s aero team will have to validate the package in both states, and the wing’s effectiveness will differ wildly between them. That is part of why a roadster RS is harder to engineer than it looks. The diffuser, splitter, and fender vents still do their work regardless of roof position, but the rear aerofoil’s contribution is fundamentally roof-dependent.
This is also where the centrally mounted quad exhaust matters. By routing the pipes through the center of the rear valence, Aston Martin frees up the corners for the diffuser to do its job, and it gives the RS a visual signature that reads as purpose-built rather than decorative.
Design and Features
Visually, the Vantage RS Roadster is essentially the coupe with the roof deleted. The reworked nose houses larger cooling apertures to manage the extra thermal load from higher power, and the deeper splitter extends the car’s visual and functional front footprint. The vented front fenders evacuate wheel-well pressure, and the rear diffuser is sized for the kind of speeds the wing is designed to exploit.
Inside, expect the regular Vantage Roadster’s layout with RS-specific trim: fixed-back seats, lighter materials where possible, and the same digital instrumentation Aston Martin has been refining since the current generation launched. The Z-fold fabric roof is the Roadster’s defining compromise, but it is also what makes the car usable as a daily driver in a way the coupe-only RS never could be.
Pricing and Availability
The Vantage RS Roadster is expected to carry a price tag around $270,000. That places it well above the standard Vantage Roadster and into serious exotic territory, but still below many limited-run specials from Ferrari and McLaren. For context, the standard Vantage starts near $191,000, so the RS premium reflects the aero package, the power increase, and the limited production that typically accompanies an RS badge.
Availability will likely be constrained, in keeping with Aston Martin’s pattern for high-performance Vantage variants. Buyers should expect a short window and a heavy options list, with the usual Q by Aston Martin personalization program available for those who want their wing in a specific shade.

- The centrally mounted quad exhaust frees the corners for real diffuser work.
Cons
- Roof-off aerodynamics make the wing’s downforce roof-dependent and harder to tune.
- Extra weight versus the coupe will blunt ultimate track pace regardless of power.
- Price near $270,000 approaches far more exclusive metal from Ferrari and McLaren.
- No confirmed figures yet, so the 700 hp target remains speculative until Aston Martin speaks.
Frequently Asked Questions
Q: What is the Vantage RS Roadster’s target competitor?
The Vantage RS Roadster is aimed directly at the Porsche 911 GT3 RS, the track-focused 911 that has defined the hardcore naturally aspirated Porsche formula. Aston Martin is using the RS Roadster to mirror Porsche’s coupe-and-open-top strategy at the top of the Vantage range.
Q: How much power will the Vantage RS Roadster produce?
The Roadster is expected to approach 700 hp from the Mercedes-AMG sourced 4.0-liter twin-turbo V8, up from the standard Vantage’s 656 hp and the Vantage S’s roughly 671 hp. That figure is a target rather than a confirmed specification, since Aston Martin has not published RS numbers.
Q: How does the Roadster’s weight compare to the coupe?
The standard Vantage Roadster carries roughly 130 lb more than the coupe, but Aston Martin will aim to shrink that gap on the RS. The useful benchmark is Porsche, which keeps the difference between its 911 GT3 and GT3 RS to about 83 lb despite the RS’s full aero package.
Q: Why does the roof matter for the RS aero package?
The fixed rear wing on the RS was tuned around a coupe roof, so with the Roadster’s top down the airflow over the cabin changes and the wing’s downforce differs from the closed-roof state. Aston Martin must validate the aero in both configurations, which is what makes an open-top track special harder to engineer than it first appears.
Q: How much will the Vantage RS Roadster cost?
The Vantage RS Roadster is expected to carry a price tag of around $270,000, positioning it well above the standard Vantage Roadster and into serious exotic territory while still under many limited-run Ferrari and McLaren drop-tops. Availability is likely to be limited in line with Aston Martin’s RS tradition.
