How does the ultimate supercar become the perfect GT racer? The lightweight MonoCage II carbon fibre chassis at the core of the 720S GT3 is the perfect basis from which to create a race car. Find out why in this week's episode of the McLaren Tech Club.

This week, Wes Jacklin, Plant Director at MCTC, describes how to build the carbon fibre monocoque that sits at the core of every McLaren.

Losing weight. It’s an obsession among our engineers. No stone (or nut, or bolt) is left unturned. They discovered that by spark-engraving the McLaren badge instead of embossing it, they could save 2.4 grams. Now, this might not seem like much… but it all adds up. And anything that lightens our cars is worth the effort.

It seems so obvious when you think about it. Your mission is to create the purest, most elemental driving experience, in an ultra-lightweight hypercar. Removing the roof and the windscreen helps achieve both, but also creates a big problem: how to protect the occupants from the vicious airstream.

Twenty-six years ago, a young man saw the original McLaren F1 in a London showroom. He couldn’t afford it, but the seed was sown. Today, he owns several McLarens, including a McLaren Senna

Made using a combination of carbon-fibre and glass, the 765LT's unique engine bay allows the roar of the 765PS 4.0 litre twin-turbocharged V8 to flood though the cabin. Connecting the driver to the car and the feel of pure LT power. Join Chief Engineer James Warner in Episode 19 of the McLaren Tech Club to find out how we did it.

Every part of the 765LT has been engineered to give the driver a pure, undiluted connection to the car. Which means you feel the road, the car’s every movement and its incredible performance. But our engineers didn’t just focus on performance. They were also looking to engineer an emotional connection with the engine. And that means sound.
