INNOVATIVE TECHNOLOGY.UNCOMPROMISED PERFORMANCE

The 12C Spider takes open-top driving to a new level. A pure McLaren, its innovative design and Formula 1™ inspired technologies make it one of the most versatile and potent supercars on the road.

RETRACTABLE ROOF

HARD NUMBERS

No roof. No compromises. That was the goal. When we developed the Retractable Hard Top (RHT), we set aggressive performance targets.  Numbers that, at the time, seemed unachievable.

WEIGHT

The mechanisms required to open, close and store the RHT roof adds weight. Weight being the enemy of performance, our engineers weren’t satisfied when they reached the 50kg weight target set for the roof. Six obsessive months later, they’d got it down to 40kgs. Making it the lightest RHT roof on the road.

DRAG

Convertibles are less aerodynamic than coupes, especially with the roof down. Working obsessively, our aerodynamicists managed to limit the increase in drag to just 7% when the roof is stowed. It is a peerless achievement.

SPEED

When you drive a convertible, you don’t want to pull over to put the roof down. The 12C Spider’s retractable hardtop roof is fully operational at speeds up to 30kph. It will also open or close in just 17 seconds.

DESIGN

The tonneau cover’s design ensures the 12C Spider’s glorious engine remains visible even when the roof is stowed. The inventive design also created 52 litres of luggage space beneath the tonneau to help maximise the space.

AERODYNAMICS

ACTIVE AERODYNAMICS

It took hundreds of hours of advanced computational fluid dynamics, weeks of wind tunnel testing and an obsession with perfection to create the contours of the 12C Spider. Technically beautiful and performance focused, the 12C Spider is an aerodynamic work of art.

EVERY CURVE. EVRY CREASE. EVERY INTAKE. EVERY MILLIMETRE OF THE 12C IS HONED TO IMPROVE AERODYNAMIC PERFORMANCE.

  • The low front accelerates and cleans airflow below the car creating downforce that maximises traction and cornering ability.
  • The Formula 1™-inspired flat underside of the car and rear diffuser generate significant levels of downforce, optimising medium and high-speed stability.
  • Designed to turn the airflow through 90 degrees, the turning vanes force air into the cooling radiators.
  • The rear haunches are shaped perfectly to feed air over the Airbrake to maximise the 12C Spider’s stopping power. The Airbrake can also be partially deployed to act as a rear wing, increasing rear downforce by 20% - with negligible effect on drag.
THE CARBON MONOCELL

CARBON FIBRE MONOCELL

We pioneered the use of carbon fibre in Formula 1™ and in production road cars. Our knowledge and experience of carbon fibre is unrivalled and our success with it is unmatched. For over 30 years, every car we have made has had carbon fibre at its core.

It took 4,000 hours to make each carbon fibre chassis on the McLaren F1. Twenty years of innovation later, it takes just 4 hours to produce the MonoCell at the heart of the 12C Spider.

UNCOMPROMISED PERFORMANCE

Our innovative approach to design means we are able to overcome the compromises inherent in open-top sports cars.

TORSION

The 12C and the 12C Spider are built on identical carbon fibre MonoCells, so they provide the same torsional rigidity, structural integrity and performance characteristics.

WEIGHT

Weighing just 75kgs, the MonoCell is lighter, stronger, stiffer and safer than comparable steel or aluminium designs.

PERFORMANCE

The design of the MonoCell ensures the 12C Spider performs and handles like a race-bred supercar. Carbon fibre does not degrade like metal, so the integrity and racing performance of the MonoCell will be maintained for decades to come.

SAFETY

The integral strength of the carbon fibre MonoCell provides a safety structure that offers exceptional levels of protection for the driver and passenger.

BRAKE STEER

BRAKE STEER

First developed for our Formula 1™ championship winning MP4-13, Brake Steer was swiftly banned in the sport because of the advantage it gave our cars. The innovative Brake Steer technology manages traction, minimises mid-corner understeer and controls oversteer when cornering at speed. This ground-breaking technology is now applied to our road cars.   

Factoring speed and steering angle, this system works out the perfect cornering trajectory. It then applies the exact amount of braking force required to the rear inside wheel as you corner – allowing the car to effectively pivot around the desired path.

PROACTIVE CHASSIS CONTROL

PROACTIVE CHASSIS CONTROL

Proactive Chassis Control (PCC) is the most radical rethink of sports car suspension design in half a century. Supple when cruising. Roll-free through the corners. PCC addresses the conflicting objectives of dynamic handling and comfortable ride, and sets new standards in both.
