Using lessons learned from the aerospace industry, we have created a revolutionary way of building an aluminium chassis, called ‘riv-bonding’. Aluminium panels are stuck together with a super-strong adhesive, and then punched with zinc-coated, boron steel rivets with up to 10 tonnes of force.
When the chassis is baked to 170ºC in the paint shop, the adhesive in this airtight aluminium sandwich becomes concrete-hard, turning the thin aluminium sheet into a phenomenally rigid structure. Take the aluminium monocoque of the F‑TYPE sports car, which weighs just 261kg, but has a very high torsional rigidity. On XE, that thinking has been taken to the next degree, making it the stiffest Jaguar saloon design yet.
Aluminium manufacturing is also quieter, cleaner and requires less energy than traditional steel chassis construction, while recycling aluminium consumes just 5 percent of the energy of creating raw aluminium, without compromising the structural integrity of the material. All of this helps to reduce the environmental footprint of a Jaguar before it even hits the road.
It’s not just in a Jaguar’s chassis where aluminium thinking is being used to lower weight for more efficient and dynamic performance, as well as enhanced durability and reliability. Jaguar Land Rover’s new generation of Ingenium engines use a cast aluminium block and head at their core that is 24kg lighter, 17 percent better in terms of friction, and five decibels quieter.
So, from their heart to their skin, our new breed of vehicles is safer, more efficient and more reliable in every way.
