McLaren 750S Spider: Light, Sharp, No Roof

Juliana here. I picked this car at Col de Turini because I trusted the math before I’d even driven it, and by the bottom of the descent, the math had done exactly what I expected it to do.

30 kilograms, and why that number is the whole story

750 hp is the headline, and it’s a real number worth taking seriously. But the number I actually care about is 30 — the kilograms McLaren cut between the 720S Spider and this car. That’s not one dramatic engineering breakthrough; it’s lighter wheels, revised bodywork, a lighter exhaust system, dozens of smaller decisions that add up to a car that turns in faster, brakes shorter, and changes direction with less inertia to fight against, without giving up a meaningful amount of the outgoing car’s outright pace.

Why weight matters more than horsepower on a real road

Anyone can chase a bigger horsepower number — it’s the easiest engineering problem to solve with money. Cutting weight without giving up structural integrity, especially on a convertible where the roof mechanism and chassis reinforcement already add mass the coupe doesn’t carry, is the harder problem, and it’s the one that actually pays off on a road with real corners rather than a straight-line dyno chart. This is the exact argument I made at Col de Turini, and it’s the reason I picked this car over two rivals with their own legitimate cases.

What actually happened at Col de Turini

I drove this car against a Ferrari F8 Spider and a Ferrari 488 Spider on the Monte Carlo Rally’s most famous stage, and the 30-kilo weight advantage showed up exactly where I said it would — through the tighter switchbacks, where less mass to redirect meant less work for the chassis every single time the road changed direction. It wasn’t a blowout. Both Ferraris made real cases of their own. But by the bottom of the descent, the lightest car in the test was also the one that felt most in control of itself.

Where it sits in this fleet

The 750S Spider is currently the lightest spider in this fleet, ahead of both the Ferrari and Lamborghini convertibles it regularly gets cross-shopped against — a genuinely different engineering priority from cars chasing bigger horsepower figures, and the reason I keep coming back to it.

The McLaren 750S Spider is bookable out of Monaco, the French Riviera, Munich, and Paris. Get in touch if you’d like to drive it yourself — or read the full Turini test to see exactly how it won.

Frequently asked questions

How much horsepower does the McLaren 750S Spider have?

750 hp, with 0-100 km/h in 2.8 seconds and a 332 km/h top speed.

What makes the 750S lighter than the 720S it replaced?

McLaren cut 30 kg through detail engineering rather than one dramatic change — lighter wheels, revised bodywork, a lighter exhaust — the kind of weight loss that shows up everywhere rather than in one headline number.

How did the 750S do against the F8 Spider and 488 Spider at Col de Turini?

It won — see the full road test for how a 30-kilo weight advantage settled an argument that started as three very different arguments about what a supercar should prioritize.
