McLaren 750S: Sharpening the Scalpel

When McLaren introduced the 720S in 2017, it was a revelation. It moved the goalposts for the entire supercar industry, offering hypercar-rivaling acceleration, a revolutionary carbon-fiber chassis, and an incredibly sophisticated hydraulic suspension system. For over half a decade, it remained the benchmark against which every other mid-engine supercar was judged.

Replacing a benchmark is incredibly difficult. Rather than throwing out the formula and starting from scratch, McLaren chose the path of meticulous, obsessive refinement. Unveiled in 2023, the McLaren 750S is the successor to the 720S.

While it looks visually similar to its predecessor, McLaren claims that 30% of the components are new or changed. The goal was not to reinvent the wheel, but to sharpen the scalpel—making the car lighter, more powerful, louder, and significantly more engaging to drive.

The Development Story: Evolving a Legend

The 720S arrived in 2017 with such towering competence that it embarrassed rivals a full price bracket above it. Road testers regularly found it running to 100 km/h in 2.8 seconds and posting lap times that troubled far more exotic machinery. It was genuinely difficult to improve upon.

McLaren’s engineers approached the 750S development with a clear philosophy: they were not looking for headline numbers but for a more honest, more communicative driving experience. The 720S had sometimes been criticized — fairly — for feeling slightly detached from the driver, its prodigious grip and stability sometimes filtering out the tactile information that enthusiasts crave. The 750S was designed to fix this, to put more texture back into the relationship between car and driver.

That required changes not just to the powertrain but to the suspension geometry, the steering calibration, the exhaust note, and dozens of smaller details throughout the cabin. The result is a car that feels meaningfully more alive than the machine it replaces, while remaining just as devastatingly fast.

The Engine: 750 PS and a New Voice

The heart of the 750S remains the formidable M840T 4.0-liter twin-turbocharged V8 engine.

To extract more performance, McLaren increased the turbocharger boost pressure and fitted the engine with lighter pistons sourced directly from the ultra-exclusive 765LT track car. They also installed a higher-pressure fuel pump and a recalibrated engine management system.

The result is a jump in output to 750 PS (740 bhp) at 7,500 rpm and 800 Nm (590 lb-ft) of torque.

However, the most noticeable change to the powertrain is auditory. A common criticism of the 720S was its slightly muted, industrial exhaust note. McLaren addressed this head-on with the 750S. They fitted a brand-new, central-exit stainless steel exhaust system that is 2.2 kg lighter than the old system. Inspired by the McLaren P1, this new exhaust delivers a much sharper, clearer, and more emotional V8 crescendo, particularly at high RPMs.

This matters enormously in context. A supercar’s sound is part of the experience — it shapes mood, it communicates mechanical information, it creates memories. The 720S was extraordinary in almost every objective metric but left some owners feeling slightly unconnected from the mechanical spectacle happening behind their shoulders. The 750S corrects this. Open the exhaust bypass valve in Sport mode and the V8 sharpens into something genuinely arresting: a hard, flat-plane bark on downchanges, a rising howl through the upper rev range.

The Diet: Lighter Than the Competition

McLaren’s core philosophy is minimizing weight, and the 750S excels in this metric. It is the lightest series-production McLaren ever built.

Through forensic weight-saving measures, the 750S is a full 30 kg (66 lbs) lighter than the 720S. In its lightest dry specification, the car weighs just 1,277 kg (2,815 lbs).

To put that into perspective, the 750S is roughly 193 kg (425 lbs) lighter than its closest competitor, the Ferrari 296 GTB (which carries a heavy hybrid battery pack).

The weight savings were found in the details:

• Wheels: New 10-spoke ultra-lightweight forged wheels save 13.8 kg.
• Seats: The carbon-fiber racing seats save 17.5 kg.
• Display: A new, fixed instrument display (removing the folding mechanism of the 720S) saves 1.8 kg.
• Glass: Thinner windshield glass saves weight high up in the chassis.

With 750 horsepower pushing just 1,277 kg, the acceleration is violent. It hits 100 km/h (62 mph) in 2.8 seconds and reaches 200 km/h (124 mph) in an astonishing 7.2 seconds.

That 200 km/h figure deserves particular attention. Seven-point-two seconds to 200 km/h is a number that puts the 750S in hypercar territory — faster than most cars wearing seven-figure price tags. It achieves this not through exotic hybrid systems or trick active aerodynamics but through the oldest formula in motorsport: less weight, more power, better tires.

PCC III: The Suspension Masterclass

McLaren’s greatest dynamic weapon has always been its suspension. Instead of traditional anti-roll bars, McLaren uses a complex, hydraulically interlinked system to control roll and heave independently.

For the 750S, this system was upgraded to Proactive Chassis Control III (PCC III). The front track was widened by 6 mm for better turn-in grip. The spring rates were softened by 3% at the front and stiffened by 4% at the rear, a change designed to make the car feel more “playful” and agile, slightly reducing the clinical neutrality of the 720S.

The steering remains hydraulically assisted, a deliberate choice by McLaren to provide the ultimate steering feel and feedback, rejecting the industry-wide shift to electric power steering.

In practice, the revised suspension setup makes the 750S noticeably more rewarding on a twisting road. Where the 720S would sometimes feel as though it was simply processing inputs through a series of algorithms, the 750S introduces a hint of rotation — a gentle, controlled willingness to let the rear of the car breathe — that makes the driver feel genuinely involved in the process of going fast. It is not an aggressive change, but it is a meaningful one.

Aerodynamics and Interior Ergonomics

Visually, the 750S features subtle aerodynamic tweaks. The front bumper has a lower, larger splitter. The “eye-socket” intakes surrounding the headlights are narrower. The most significant visual change is the active rear wing, which is 20% larger in surface area than the 720S but actually weighs 1.6 kg less due to its carbon-fiber construction.

Inside the cabin, the ergonomics were vastly improved. The most welcome change is the introduction of the McLaren Control Launcher (MCL).

Previously, to access the dynamic modes, the driver had to press an “Active” button on the center console before turning the dials. Now, the controls for powertrain and handling modes are mounted directly on the binnacle surrounding the instrument cluster (similar to the Artura). The MCL button allows the driver to save their favorite combination of aero, handling, powertrain, and transmission settings and activate them all instantly with a single press.

The instrument cluster itself is new — a slimmer, fixed unit that eliminates the folding display of the 720S. This saves weight and improves reliability, while also giving the cabin a cleaner, more purposeful character. The overall interior quality has been elevated throughout, with improved material choices and tighter assembly.

750S vs Ferrari 296 GTB: The Defining Rivalry

In 2024, the obvious comparison point for the 750S is Ferrari’s 296 GTB — a plug-in hybrid supercar combining a twin-turbo V6 with an electric motor for a combined 830 PS. It is, by any objective measure, a remarkable piece of engineering.

The Ferrari edges the McLaren in combined power output and benefits from additional electric torque at low speeds. Its naturally aspirated character, replaced by the six-cylinder turbocharged hybrid, has been partially compensated by an extraordinarily well-tuned drivetrain. Many journalists consider it the most complete small Ferrari in decades.

What the 750S offers in return is simplicity, transparency, and those 193 kg of absent weight. The McLaren’s hydraulic steering delivers more information to the driver’s hands. Its lighter chassis responds to changes in road surface with greater immediacy. On a flowing mountain road, the experience is different in quality as well as quantity — not faster necessarily, but more communicative, more demanding of the driver’s attention, more honest about the physics involved.

The 296 GTB has the more impressive specification sheet. The 750S offers the more direct experience. Which you prefer says something about what you want from a supercar.

The Pure Combustion Benchmark

In an era rapidly shifting towards hybridization and heavy battery packs, the McLaren 750S stands out as a triumphant celebration of the pure, lightweight, internal combustion supercar. It takes everything that made the 720S brilliant and sharpens it, resulting in a car that is more engaging, more emotional, and devastatingly fast.

Collector value for the 750S should remain strong for exactly this reason. As the automotive industry moves inexorably toward electrification, cars that deliver this level of performance through pure mechanical means — no battery, no electric motor, just combustion chemistry and carbon fiber — will become increasingly rare and, eventually, increasingly prized.

The 750S may well be remembered as the finest expression of what McLaren could do with an internal combustion engine before the world changed around them.
