The S65 represents a genuine motoring milestone, pushing the AMG performance division to its absolute limits while delivering something that feels less like a car and more like a statement. This machine sits at the crossroads of automotive marvel and Germanic self-indulgence, and honestly, that tension is exactly what makes it so compelling.
The S-Class Coupé version brings two-door drama to the top-of-the-range twelve-cylinder world, wrapping benchmark performance and exquisite appointments inside irresistible contours finished in high-sheen chrome.
Under that long hood lives the legendary AMG V12 biturbo pumping out 463 kW, 630 hp, and a earth-shaking 1000Nm of torque figures that make the S 65 genuinely unique in its segment alongside its MAGIC BODY CONTROL chassis and curve tilting function guided by ROAD SURFACE SCAN.
Mercedes-Benz S65 AMG
Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH, summed it up perfectly when he said this car surpasses even the highest expectations across driving dynamics, comfort, and equipment.
The S-Class has always stood for luxurious refinement, but the S65 AMG pushes that philosophy into rarefied territory that rivals the GT family in sheer excitement while keeping its grand touring soul intact.
We drove this car following the 2017 Frankfurt show announcement of a facelifted successor, choosing the S 65 over the S500 with its V8 and even the Affalterbach-built S63 because when 12 cylinders beat eight cylinders, there really is no going back.
From Bad Driburg near the Bilster Berg race resort all the way to the Le Shuttle train carriages of the Channel Tunnel, this car filled every parking space it attempted with absolute authority, announced every cold start with a loud bark from its quad tailpipes, and turned neighbours into involuntary spectators the moment you pressed the engine start button with your foot on the brake pedal.
Engine & Performance
The heart of this car beats with a six-litre bi-turbo V12 featuring three valves per cylinder, delivering a staggering 612bhp and 737lb ft of torque that translates to 1000Nm, which means this remains the most powerful production saloon in the world.
It rockets to 62mph in just 4.4 seconds on the way to an electronically limited top speed of 155mph, leaving the Audi RS4 and BMW M5 scrambling in its wake despite the car tipping the scales at over two tonnes.
The raw number that truly impresses arrives at just 1000rpm, where 420lb ft of torque is already available, climbing to 552lb ft with just 500 revs more that kind of low-down grunt delivers a turn of speed that genuinely shocks first-time passengers.
The AMG V12 biturbo twin-turbo engine produces 463 kW at 4800-5400 rpm with a maximum of 1000 Nm between 2300-4300 rpm, launching the S 65 AMG Coupé from standstill to 100 km/h in 4.1 seconds toward a 250 km/h electronically limited ceiling.
Fuel consumption sits at 11.9 litres per 100 kilometres on the NEDC combined cycle, producing 279 g/km of CO2 actually besting every rival in the segment while cutting 2.4 litres per 100 kilometres versus the old CL 65 AMG and meeting the tough EU6 emissions standard.
The sensational drive this engine provides comes through effortless power delivery across all speed ranges, wrapped in refined engine running characteristics and that unmistakable AMG V12 sound that rewards your right foot with tremendous pulling power every single time.
On the autobahn, leaving a 130kph zone and entering a derestricted section, this car transforms completely pushing from 81mph all the way to its 155mph V-max feels like a Golf R sprinting from 30-100mph, delivering relentless shove that feels more turbine than turbo.
Against the S63, the S 65 proves monstrously quick at high speeds identical 0-62mph times exist because putting 738lb ft through a pair of road tyres limits launches, but past 70mph the S63 simply cannot keep up, all while the exhaust note channels a perturbed Chinook.
The flexibility of this twin-turbo motor reveals itself instantly lightly touch the accelerator pedal and it purrs, demand more with your right foot and the character shifts dramatically toward something far more urgent and thrilling.
Key Data at a Glance
The S 65 AMG Coupé carries displacement of 5980 cc paired with an output of 463 kW and 630 hp between 4800-5400 rpm, representing the absolute summit of what Mercedes-AMG engineering produces for road use.
Maximum torque of 1000 Nm arrives between 2300-4300 rpm while fuel consumption on the NEDC combined cycle measures 11.9 l/100 km with CO2 emissions of 279 g/km placing it in efficiency class G.
The headline performance figures that matter most show acceleration from 0-100 km/h in 4.1 seconds and a top speed of 250 km/h both electronically limited by the V12 specifications that define this extraordinary machine.
Transmission
The AMG SPEEDSHIFT PLUS 7G-TRONIC sends power efficiently to the rear axle through three distinct character modes selectable via a button on the center console Controlled Efficiency, Sport, and Manual each reshape how the S 65 feels and responds beneath you.
In Sport and Manual the transmission cuts ignition and injection briefly under full load upshifts, shortening shift times dramatically while adding an audibly more emotive tone to every gearshift that makes the whole experience feel genuinely theatrical.
The ECO start/stop function activates automatically in transmission mode C, while the five-speed automatic Speedshift system delivers smooth, seamless surges of acceleration with the powertrain reinforced specifically to handle the enormous torque this engine produces across all three individual modes, guaranteeing emotional appeal and real sportiness every time you push through the button on the console.
The MCT gearbox handles fast driving competently about 98% of the time, but during aggressive cornering it occasionally struggles to select the right ratio quickly enough on corner exit thankfully, the engine flexibility of the V12 means this rarely matters in practice.
The dynamism this transmission enables during Sport mode genuinely transforms the S 65 from luxury cruiser into something with authentic sporting character and emotional appeal that the standard S-Class simply cannot replicate.
Each of the three individual modes serves a different version of the S 65 experience, from whisper-quiet Controlled Efficiency cruising through to full-blooded Manual control with upshift lights blazing on the windscreen.
Handling & Ride
Throwing a two-tonne machine into a tight bend at speed reveals the one honest limitation of the S 65 rear passengers risk headbutting the dashboard if you scrub speed too aggressively, and the sheer heft of this huge car makes genuine delicacy of response and reaction through corners an unrealistic expectation.
The S-Class DNA runs deep here, delivering lightness and play through the steering alongside a degree of detachment from the drive that suits executive cruisers perfectly but sits slightly at odds with the car’s obvious sporting intent the S 65 was never meant to challenge a Ferrari through a mountain pass.
Think of this car as a spectacular four-seater GT built for continent-crushing rather than circuit conquest, and the handling suddenly makes complete sense within the broader experience of owning something this special and massive.
Active Curve Control comes as standard fitment and genuinely earns its keep by enabling fairly flat directional changes particularly in Sport mode, though switching to Curve mode produces a peculiar opposite reaction to bodyroll that feels unnaturally amplified compared to anything a natural Pendolino-style tilting motion produces.
The system pushes back against lean rather than flowing with it, creating a sensation that feels unsettling for the driver and potentially vomit-inducing for a passenger when you inevitably get tempted to press on through a flowing sequence of bends.
The honest advice is to leave this car in its natural waftmobile mode, embracing the ride quality and the V12 rather than fighting the cornering characteristics the two tonnes of weight simply demand respect and reward patience with extraordinary comfort at every legal speed.
Suspension
This car introduced a genuine world first with twin sliding calipers that reduce heat transfer to the brake fluid just like a floating caliper while retaining the full stopping power of a large fixed caliper engineering ingenuity hiding behind a polished exterior.
Ceramic composite brake discs reduce unsprung weight meaningfully, which feeds directly into improved ride quality and sharper body response, connecting the braking system cleverly to the overall suspension philosophy of the car.
The MAGIC BODY CONTROL system ties everything together through Active Body Control, ROAD SURFACE SCAN, and the curve tilting function that allows the S 65 AMG Coupé and S63 AMG Coupé to lean into corners the way a motorcyclist or skier naturally does, converting lateral acceleration into something that feels like driving on a banked curve.
On country roads the curve tilting function elevates motoring enjoyment and comfort simultaneously you select it as one of three drive modes via the ABC switch and it operates between 15 km/h and 180 km/h, tilting the body in fractions of a second depending on curve radius and vehicle speed.
A stereo camera behind the windscreen reads road curvature up to 15 metres ahead while an additional lateral acceleration sensor feeds the system real-time data the S 65 AMG Coupé essentially reads the road before you arrive at each bend.
ROAD SURFACE SCAN handles surface undulations proactively, adjusting the MAGIC BODY CONTROL suspension in advance to eliminate unwanted chassis movement across both Comfort mode and Sport mode, while the specific elastokinematics tuned into the AMG sports suspension reward a dynamic driving style with genuine directness that surprises anyone expecting pure luxury softness.
Steering
The electromechanical speed-sensitive sports steering with variable steering ratio represents one of those engineering solutions that works so seamlessly you only notice it when you think back on how natural the S-65 felt to place accurately at speed.
In Comfort mode the system increases steering assistance to reduce fatigue during long motorway cruises, while selecting Sport mode delivers a sportily stiff feel that sharpens agility and maintains driving safety even at high speeds where precision matters most.
The pre-programmed curves for power assistance enhance both road surface feedback and steering precision simultaneously, giving the driver a genuine connection to what the front tyres are doing while the variable steering ratio optimises vehicle handling throughout every corner.
Brakes
The AMG engineering team achieved a genuine world first with the twin sliding calipers fitted to the S-65, reducing heat transfer to the brake fluid in the manner of a floating caliper while preserving the full stopping power associated with a large fixed caliper design.
Ceramic composite brake discs cut unsprung weight significantly, translating directly into sharper ride quality, better agility, and more responsive driving dynamics the weight reduction works invisibly but you feel every benefit through the seat of your trousers.
The standard AMG high-performance composite brake system features brake callipers in a grey finish with red callipers available optionally, and the fully ceramic ceramic high-performance composite brake system option saves over 20 percent in mass, reducing unsprung masses further and sharpening ride comfort and driving dynamics in measurable ways.
Wheels
The standard 19in AMG alloys sit inside dramatically flared wheelarches complemented by aggressive side skirts that give the S 65 its planted, purposeful stance from every angle.
The V12 Coupé upgrades to stunning forged wheels in a multi-spoke design measuring 8.5 x 20 at the front and 9.5 x 20 at the rear, wrapped in 255/40 R 20 and 285/35 R 20 tyres that fill those arches perfectly.
Each wheel features 16 spokes that twist toward the centre, creating light-catching contours that radiate toward the wheel hub and make the already large 20-inch alloys appear even more imposing a clever visual trick that amplifies the S-65’s road presence dramatically.
The ceramically polished, high-sheen finish results from an elaborate finishing process involving initial polishing, followed by manual grinding of each light-alloy wheel using two stages of grinding pellets to achieve the desired deep sheen before clear varnish sealing protects the surface permanently.
Every wheel carries a high-quality bolt-on wheel bolt cover in forged aluminium shaped like a centre lock from motorsport, with AMG lettering incorporated directly into the rim design as a subtle but unmistakable identifier.
Three alternative forged wheels in the same 8.5 x 20 and 9.5 x 20 format are available optionally, including one striking variant with a matt black finish and high-sheen rim flange that pairs magnificently with darker exterior colors on the S-65 AMG Coupé.
Exterior Design
Standing beside the S-65 in broad daylight, the 19in AMG alloys, aggressive side skirts, and dramatically wide wheelarches create a visual package that communicates serious intent without resorting to boy-racer theatrics.
The massive front apron houses oversized air intakes while the chunky rear end features a pair of twin exhausts that complete a repackaging job so thorough the S 65 looks like an entirely different proposition from a standard S-Class.
Every surface carries V12-specific chrome detailing the central Mercedes star on the front apron, the twin blade radiator grille, all air intake grilles, the A-wing trim strip, side flics acting as air deflector elements, and the front splitter itself all receive chrome-trimmed treatment that works best against dark paintwork to create maximum visual drama.
The front splitter performs real aerodynamic work by reducing lift at the front axle, while the gap above it channels airflow directly to the separate engine oil cooler mounted behind.
On the flanks, V12 BITURBO lettering on the wings and chrome inserts in the side skirts harmonise with the polished forged wheels to create a cohesive, thoroughly resolved appearance.
The AMG sports exhaust system exits through chromed twin tailpipes in V12 design integrated into the rear apron, sitting above a diffuser insert finished in high-gloss black that contrasts sharply with the high-sheen chrome trim element above it an exterior that combines sensual clarity, supreme sportiness, and irresistible contours into something genuinely memorable even when squeezed into a parking space with massive alloys threatening the margins of those narrow train carriages on Le Shuttle.
Interior
Settling into the S-65 cabin feels like entering a private members club the sports seats upholstered in designo AMG Exclusive nappa leather with diamond-pattern design and precisely delineated perforations that deliberately avoid areas of stitching set an immediate tone of extraordinary quality.
Electric adjustment, memory function, seat heating, and climate control come standard, while more contoured seat cushions and backrests provide genuine lateral support during spirited driving though the bolstering system during cornering feels slightly aggressive until you switch it off, revealing seats that rank among the most comfortable and adjustable available in any car at any price.
AMG badges feature on all four backrests and the AMG logo sits embossed on the front centre console, small details that remind occupants constantly of where this car sits in the hierarchy.
The Exclusive package wraps the entire cabin in nappa leather the roof liner, leather-lined dashboard, door centre panels in diamond-pattern design, leather-clad roof grab handles, chromed door pins, and illuminated white AMG stainless steel door sill panels all contribute to an ambience that genuinely rivals the chic interiors of Bentley and Rolls-Royce.
Colour choices for the designo AMG Exclusive nappa leather upholstery span black, porcelain/espresso brown, saddle brown/black, and crystal grey/black enough variety to personalise the experience meaningfully.
The quilted diamond pattern adds real design flair to the glitzy interior finished with the highest-quality Merc parts, and while the optional £3980 AMG carbonfibre trim available on our test car looked striking.
It felt slightly out of step with the broader luxury focus you genuinely need no options because the standard equipment array on a car approaching £200k includes driver-assistance tech, night vision, panoramic sunroof, and the exquisitely integrated Burmester 3D speaker hi-fi installation that transforms the cabin into a concert hall.
Steering Wheel
The three-spoke sports steering wheel puts everything you need directly at your fingertips shift paddles for manual gear changes, a distinctly contoured rim wrapped in perforated leather through the grip area, and a polished metal insert carrying AMG lettering that ties the wheel’s design language directly to the broader interior theme.
Vehicle control through this wheel feels natural and precise, communicating enough road feel to keep the driver engaged without overwhelming with information during relaxed cruising. The entire assembly reinforces the sense that the S-65 takes its sporting credentials seriously even within its luxury mission.
Instrument Cluster & Technology
The AMG instrument cluster displays engine speed and vehicle speed on two stunning animated round dials rendered on a 31.2 centimetre high-resolution colour TFT display the typography, red and silver needles, 360 km/h scale speedometer, and V12 BITURBO lettering in the rev counter create a specifically AMG look that separates this from any standard S-Class immediately.
Opening the driver’s door triggers an AMG start-up screen on the right display while an animated S-65 AMG Coupé appears in the instrument cluster a small theatre that never loses its appeal regardless of how many times you experience it.
The head-up display projects vehicle speed, speed limits, navigation directions, traffic signs, and DISTRONIC PLUS data onto the windscreen, with the upshift bar in colour and available gears for manual gear change displayed exclusively in Manual transmission mode a virtual colour display measuring 21 x 7 centimetres that appears to hover above the bonnet roughly two metres ahead of the driver.
The touchpad system simplifies control of radio, telephone, and the navigation system through an input area of 6.5 x 4.5 centimetres integrated into the handrest with a protective cover over the keypad far more intuitive than conventional rotary controllers.
All infotainment functions flow through this single interface, reducing the cognitive load of managing multiple systems at highway speed. Together the instrument cluster, head-up display, and touchpad create a connected, information-rich environment that keeps the driver fully informed without ever feeling cluttered or distracting.
Safety & Driver Assistance
Mercedes-Benz calls its comprehensive safety philosophy Intelligent Drive, representing a decade of evolution from the original PRE-SAFE system through DISTRONIC PLUS into a new dimension where comfort and safety genuinely merge into a single seamless experience across the S-Class Coupé.
The S-65 AMG Coupé establishes new standards in both active safety and passive safety, with systems working continuously in the background to protect occupants and other road users across every conceivable driving scenario at any speed.
Standard equipment includes a 360° camera, Active Parking Assist with PARKTRONIC, the magnificent Burmester high-end 3D surround sound system, and the full Driving Assistance package Plus encompassing DISTRONIC PLUS with Steering Assist, Stop&Go Pilot, PRE-SAFE Brake, BAS PLUS with Cross-Traffic Assist, Active Blind Spot Assist, Active Lane Keeping Assist, PRE-SAFE PLUS, Seat Comfort package for both driver and front passenger, AMG Exclusive nappa leather upholstery, and the KEYLESS-GO package a suite of technology that makes the roughly ten years of development investment immediately and obviously worthwhile across every journey.
Battery
The S-65 AMG Coupé carries a lithium-ion battery as standard equipment, representing a meaningful upgrade over any conventional battery concept previously fitted to vehicles of this type.
With a capacity of 78 Ah, this single unit replaces both the starter battery and the backup battery simultaneously, achieving a weight saving of over 20 kg through innovative technology that contributes directly to sharper dynamics and reduced overall mass.
That 20 kg reduction might sound modest against the car’s total weight but at the unsprung and low-mounted extremities of the vehicle it makes a genuine, measurable difference to how S 65 rides and responds.
AMG V12 Heritage & Range
The S-65 AMG Coupé represents the fourth AMG high-performance car built around a V12 engine joining the S 65 AMG, SL 65 AMG, and G 65 AMG in a portfolio that makes Mercedes-AMG the only manufacturer in the world offering such a wide range of twelve-cylinder vehicles across Coupé, Saloon, Roadster, and Off-roader body styles.
The lineage traces back to 2003 when Mercedes-Benz introduced the CL 65 AMG in C215 model series form, followed by the C216 model series between 2007 and 2014 as the direct predecessor to the current car a V12 biturbo tradition spanning over two decades of continuous development in Affalterbach.
The one man, one engine build principle means the technician who assembles each AMG 6.0-litre V12 biturbo engine signs the AMG engine plate personally.
Creating under that carbon fibre and aluminium engine cover not just a powerplant but a signed piece of mechanical art whose precision and production quality reflect the peerless DNA of the Mercedes-Benz high-performance brand something connoisseurs recognise immediately as the absolute pinnacle of engine design when they lift the bonnet.
Price & Value
The S 65 arrives with a £145,365 price tag that demands serious contemplation to contextualise within the Mercedes-Benz range, the S320 CDI in L specification costs £58,975 while the S500L sits at £73,770 and still reaches 62mph in 5.6 seconds with considerably less drama and considerably more fuel remaining in the tank.
The re-engineering and exclusivity that separates the S 65 from standard S-Class offerings is genuinely undeniable, but spending the equivalent of two Audi S8s or a Bentley Flying Spur with £30,000 in change requires a very specific kind of conviction that the AMG badge at £71,595 of perceived premium genuinely delivers sufficient return.
The S63 Coupé costs a further £57,870 less than the S 65, and while the flagship status, badge, and spoiler attract buyers who will likely never use the composite brakes or integrated lap timer,
The people who truly understand the V12 difference the engineers, the connoisseurs, the drivers find the investment entirely rational given what the three-pointed star delivers versus Aston Martin, Bentley, and Rolls-Royce equivalents like the Vanquish, Continental GT, and Wraith in terms of understated rarity and genuine mechanical substance over brand cache alone.
Verdict
The S65 functions as a performance flagship and marketing tool simultaneously, elevating the entire model range and AMG brand simply by existing at the apex of what is technically achievable within a four-door luxury format.
It targets a very specific aspirational demographic not the BMW 318i driver ordering M-Sport alloys to signal ambition, but the buyer who wants quality, refinement, and class woven together with a level of performance so extreme it borders on antisocial.
The S 65 looks terrifying, performs like Satan’s mistress unleashed on an autobahn, and remains unique in a way that neither the paper specifications nor the metal reality fully prepares you for it tugs at the heartstrings in a manner the S63 simply cannot match, purely because of that extraordinary V12 powerplant beating beneath the long hood.
On paper the case against buying the S 65 appears resounding the numbers justify the S63 overwhelmingly on rational grounds, and the three-pointed star faces genuine questions about brand cache against Aston Martin, Bentley, and Rolls-Royce in this sector.
In the metal, though, the S 65 presents a completely different argument it sells in far fewer numbers than the Vanquish, Continental GT, or Wraith respectively, meaning only those who truly understand the investment will ever recognise and appreciate what you have chosen.
The astonishing V12 makes this the right choice for anyone seeking understated rarity with authentic performance substance the S 65 remains one of the most extraordinary machines the AMG division has ever produced, full stop.
