McLaren F1

Avoiding unnecessary mass

In the pursuit of efficient performance, we trim weight to its absolute bare minimum. That’s why we designed the McLaren F1’s seats to avoid conventional and bulky seating frames, instead developing specially moulded carbon composite shell seats, upholstered in leather just 0.7mm thick.

Everything adds up

Saving weight can significantly improve vehicle dynamics. Some car manufacturers throw kilos of excess weight onto a car in the shape of bolt-head sizes and washer thicknesses that just aren’t necessary. This can all add up to a significant weight disadvantage. So, from the outset it became the F1’s number one design consideration.
Famously, the F1 became the world’s first production car to have a chassis and body built entirely of ultra-light carbon fibre composites (CFC), an aerospace material that McLaren pioneered in 1981 with the world’s first CFC Formula 1 car. But the obsession with lightweight innovation didn’t end there:

Car stereo

The smallest and lightest ever made, the stereo featured some ingenious innovations. The hi-fi supplier rushed forward the development of their aluminium magnet speaker, which weighed half that of a standard speaker. McLaren also demanded no more than five knobs, to save weight. The F1’s central driving position also delivered an inherent weight saving, as there was no need for a balance knob.

Titanium toolkit

Our uncompromising lightweight approach even extended as far as the car’s toolkit. It was gold-plated and made of aerospace grade titanium: as strong as steel but almost 50% lighter.

Record-breaking performance

The F1’s phenomenal power-to-weight ratio helped it break the world speed record for a production car (at a speed of 240.1mph) and hold it for over 10 years. A modified, even more lightweight F1 won Le Mans in 1995 at its first attempt, beating a range of purpose-built racers.
