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 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.

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.

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.

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 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.
