Open-top supercars have traditionally promised an unfiltered, visceral experience, often equating the removal of a roof with an increase in raw noise, untamed drama, and a perceived reduction in control. The prevailing wisdom suggests that sacrificing a fixed roof comes with inherent compromises to a vehicle’s structural integrity and dynamic prowess, making the driving experience more about sensory overload than surgical precision. But what if a supercar could shed its roof without shedding its composure? What if the absence of a lid didn’t just maintain the status quo but actually refined the experience, blending extreme performance with an unprecedented level of civility? This intriguing question leads us directly to the doorstep of the 2020 McLaren 720S Spider, a machine that challenges every preconceived notion about what a convertible supercar can be. Is this the most civilized supercar… or a missile in disguise?
Background & Heritage: Forged in Carbon, Refined by Racing

The story of the McLaren 720S Spider, and indeed any McLaren road car, is inextricably linked to a legacy steeped in motorsport dominance and pioneering engineering. From Bruce McLaren’s audacious racing ventures in the 1960s to the legendary Formula 1 successes and the awe-inspiring Can-Am machines, McLaren has always been about pushing boundaries. This relentless pursuit of speed and innovation translated into road car production with the iconic McLaren F1 in the 1990s, a car that redefined the term “supercar” and etched carbon fiber monocoque construction into the automotive lexicon. After a brief hiatus and a collaboration with Mercedes-Benz for the SLR McLaren, the company re-entered the road car arena with renewed vigor in 2011, launching the MP4-12C – a car that, while perhaps lacking the F1’s romanticism, set new benchmarks for technological sophistication and dynamic capability.
The MP4-12C laid the foundation for McLaren’s modern three-tier hierarchy: Sports Series, Super Series, and Ultimate Series. The 650S, an evolution of the 12C, refined its predecessor’s formula, honing its aesthetics and amplifying its performance. However, it was the 720S, unveiled in 2017, that truly marked a paradigm shift within the Super Series. It wasn’t merely an update; it was an entirely new car, 90% new components from the ground up, designed to be lighter, faster, and more dynamically capable than anything McLaren had produced outside of its Ultimate Series. Its design, often described as “biomimicry,” drew inspiration from nature, emphasizing extreme aerodynamic efficiency and a visually striking form that perfectly encapsulated its function. The distinct “eye socket” headlights, for instance, were not just aesthetic flourishes but integral air intakes for cooling the front radiators, a testament to McLaren’s unyielding “form follows function” philosophy.
Bringing this level of engineering prowess to an open-top variant typically presents significant challenges. Convertibles often require substantial structural reinforcement to compensate for the removed roof, adding weight and compromising torsional rigidity. This invariably leads to a less precise, more flexible driving experience compared to their coupe counterparts. Yet, McLaren’s profound expertise in carbon fiber construction, a technology they’ve championed for decades, provided a crucial advantage. The 720S was built around the Monocage II, an incredibly stiff and lightweight carbon fiber monocoque. For the 720S Spider, McLaren developed the Monocage II-S, a subtly modified version that retained nearly identical structural integrity to the coupe. This bespoke carbon tub, with its integrated rollover protection system, meant that the Spider barely needed any additional reinforcement, resulting in a weight penalty of just 108 pounds (49 kg) compared to the coupe. This minimal increase is a testament to McLaren’s unwavering commitment to engineering excellence, ensuring that the Spider variant would sacrifice none of the coupe’s dynamic brilliance.
This commitment to structural integrity in an open-top supercar is what truly sets the 720S Spider apart in its lineage and among its rivals. While other manufacturers might compromise on rigidity or add considerable mass to their convertibles, McLaren leveraged its carbon fiber heritage to deliver a virtually uncompromised experience. The 720S Spider, therefore, isn’t just another open-top variant; it’s a profound statement about what’s achievable when advanced materials and meticulous engineering converge. It carries forward McLaren’s ethos of relentless innovation, blending the visceral thrill of open-air driving with the surgical precision and breathtaking performance that has become synonymous with the Woking-based manufacturer. The evolution from the F1’s carbon tub to the 720S Spider’s Monocage II-S underscores a continuous thread of engineering brilliance, making the Spider a true heir to McLaren’s performance legacy.
Engineering & What’s Under The Hood: A Symphony of Speed and Precision

At the heart of the McLaren 720S Spider lies the formidable M840T engine, a 4.0-liter twin-turbocharged V8 power plant that stands as a masterpiece of modern internal combustion engineering. This engine, internally designated as M840T, is a larger and significantly revised version of the 3.8-liter unit found in its predecessors. It unleashes a staggering 710 horsepower (720 PS, hence the name) at 7,500 rpm and a massive 568 lb-ft (770 Nm) of torque from 5,500 to 6,500 rpm. Key to its ferocious power delivery are the low-inertia twin-scroll turbochargers, which spool up incredibly quickly to virtually eliminate turbo lag, providing an immediate and relentless surge of power. The flat-plane crankshaft, a hallmark of high-performance V8s, contributes to its unique, aggressive sound profile while allowing the engine to rev freely and rapidly, delivering peak power deep into the RPM range. Complementing this, a dry-sump lubrication system allows the engine to be mounted lower for a better center of gravity and ensures consistent oil delivery even under extreme cornering forces, crucial for a track-capable machine.
The M840T engine channels its immense power through a lightning-fast 7-speed Seamless Shift Gearbox (SSG). This dual-clutch transmission is renowned for its incredibly rapid gear changes, executed with a precision that borders on telepathy. It features McLaren’s “Inertia Push” technology, which briefly exploits the engine’s rotational inertia to deliver an almost imperceptible surge of torque during upshifts in Track mode, further enhancing the sensation of continuous acceleration. This gearbox is not just about speed; it’s about seamless integration with the driver’s intent, offering manual control via beautifully sculpted carbon fiber paddle shifters that click with satisfying authority. The transmission’s algorithms are highly sophisticated, adapting to driving style and selected mode (Comfort, Sport, Track) to ensure optimal gear selection whether cruising sedately or attacking a racetrack corner with full commitment.
Underpinning the 720S Spider’s exceptional dynamics is its revolutionary Proactive Chassis Control II (PCC II) suspension system. This isn’t a traditional anti-roll bar setup; instead, it uses hydraulically cross-linked dampers at each corner, interconnected and controlled by a network of 12 sensors. These sensors monitor wheel acceleration, body motion, and steering input, feeding data to an onboard algorithm that can predict and react to road conditions with astonishing speed. The system can instantly adjust damping forces to suppress body roll, dive, and squat without the need for conventional mechanical anti-roll bars. This ingenious design allows for incredible roll stiffness during hard cornering while simultaneously providing a remarkably compliant ride over broken surfaces, an almost paradoxical blend of comfort and performance that few other supercars can match. In essence, PCC II allows the 720S Spider to be both a supple grand tourer and a track weapon, adapting its character on the fly.
Aerodynamics play a critical role in the 720S Spider’s performance, a testament to McLaren’s holistic approach to engineering. The car’s sleek, organic form is a masterclass in aerodynamic efficiency, with every surface meticulously sculpted to manage airflow. Key active aerodynamic elements include the full-width, deployable rear wing, which serves multiple functions: it acts as an airbrake, increasing drag to shorten stopping distances; it optimizes downforce during high-speed cornering to enhance grip; and it can adjust its angle to reduce drag for maximum straight-line speed. The unique “eye-socket” headlight design incorporates air intakes that channel cooling air to the front radiators, contributing to both engine performance and aerodynamic stability. Even the dihedral doors are designed to guide air efficiently around the car’s flanks. The carbon fiber Monocage II-S tub, as previously mentioned, is not just about rigidity but also weight savings, contributing to a dry weight of approximately 3,190 lbs (1,449 kg). This lightweight construction, combined with the active aero, advanced suspension, and potent powertrain, ensures the 720S Spider is a complete performance package, a meticulously engineered missile disguised in an elegant, carbon fiber shell.

The moment you press the throttle, the full force of its 710 horsepower is unleashed with a ferocity that is genuinely startling. The 0-60 mph sprint is dispatched in a breathtaking 2.8 seconds, a figure that puts it in the upper echelons of modern supercars. The acceleration doesn’t wane; it feels relentless, pushing you back into the contoured seats as the car surges past 100 mph in just 5.2 seconds and reaches 124 mph (200 km/h) in an astonishing 7.8 seconds. The quarter-mile marker disappears in a mere 10.4 seconds, with the car still pulling hard towards its top speed of 212 mph (341 km/h) with the roof up, or a still blistering 205 mph (330 km/h) with the roof stowed. This isn’t just fast; it’s warp-speed, delivered with an almost surreal sense of control.
What truly distinguishes the 720S Spider’s performance is not just the raw numbers, but the way that power is delivered and managed. The surgical precision mentioned in the initial script is immediately apparent in the steering feel. It’s hydraulically assisted, offering a level of feedback and directness that electronic power steering systems often struggle to replicate. Every nuance of the road surface is communicated through the wheel, allowing the driver to place the car with unerring accuracy. The Proactive Chassis Control II (PCC II) system truly shines here, effortlessly transitioning between modes. In Comfort, it glides over imperfections with a surprising degree of compliance for a supercar, making longer journeys genuinely palatable. Switch to Sport or Track, and the dampers firm up, body roll becomes virtually non-existent, and the car transforms into a laser-guided instrument, eagerly carving through corners with an agility that belies its substantial power. The active aero rear wing deploys precisely when needed, gluing the car to the tarmac and instilling immense confidence at high speeds.
The braking performance is equally phenomenal, thanks to the standard carbon ceramic brakes with six-piston calipers at the front and four-piston at the rear. These provide immense stopping power, hauling the car down from high speeds with astonishing efficiency and fade resistance, even after repeated hard applications. The pedal feel is firm and progressive, allowing for precise modulation. With the retractable hard top (RHT) roof deployed, the experience is almost indistinguishable from the coupe – the carbon fiber Monocage II-S ensures there’s no perceptible scuttle shake or flex, maintaining the same structural integrity and dynamic balance. However, the real magic happens when the roof is stowed. In just 11 seconds, even while driving at speeds up to 31 mph (50 km/h), the lightweight carbon fiber roof retracts gracefully, disappearing beneath a tonneau cover. With the roof down and the rear window (which doubles as a wind deflector) partially lowered, the roar of the twin-turbo V8 becomes even more intoxicating, a pure, unadulterated soundtrack to the blistering performance.
Driving the 720S Spider isn’t about fighting the car; it’s about working with it. McLaren has meticulously engineered a machine that responds intuitively to driver inputs, making extreme performance feel remarkably accessible. The visibility, often a concern in mid-engined supercars, is surprisingly good thanks to thin A-pillars and generous glass areas, including the unique electrochromic glass roof panel option that can be switched from opaque to transparent at the touch of a button. The interior, while driver-focused, doesn’t compromise on comfort, with supportive seats and a well-thought-out McLaren Driver Interface that includes the innovative folding instrument cluster, which can retract to display only essential information for track driving. The open-top experience enhances the auditory drama and sensory connection to the environment without introducing the usual compromises of wind buffeting or structural instability. This seamless blend of raw speed, pinpoint accuracy, and surprising refinement is what makes the 720S Spider so compelling, redefining what it means for a supercar to deliver an “effortless” experience at the absolute limit.
