JLR hybrid composite dashboard beam cuts 50,000 tons of CO2, rethinks vehicle safety

Luxury automotive manufacturer Jaguar Land Rover (JLR, Gadyon, U.K.) has reengineered the instrument panel crosscar beam — one of the most structurally important but carbon-intensive components of a vehicle’s system — using composite materials.

The crosscar beam, which spans the width of the vehicle behind the dashboard, is a critical structural backbone in a vehicle’s cockpit, playing a key role in passenger safety, protecting occupants and mounting airbags. It also reduces noise and vibration to keep the cabin calm and refined. Traditionally made from magnesium or steel, JLR’s crossbeam structure is a hybrid — using both fiber-reinforced composites and steel. 

Through the removal of carbon‑intensive magnesium from the crosscar beam, this innovation is projected to cut more than 50,000 tonnes of CO_₂ annually (based on an estimated future annual projection of 270,000 crosscar beams being manufactured, compared to a magnesium crosscar beam). This is equivalent to the average yearly energy use of approximately 17,000 U.K. homes. 

“Redesigning a structural component like this isn’t just a straight materials swap — it’s a complex engineering challenge,” says Matthew Atkinson, lead research engineer at JLR. “Working collaboratively with our suppliers, we had to ensure the new hybrid material met exacting standards for safety, refinement and durability, while delivering a significant CO^₂ reduction. It’s a clear demonstration of how research and collaboration can drive meaningful sustainability improvements without compromise.”

Initially a research project with suppliers Celanese (Dallas, Texas, U.S.), CCP Gransden (Newtownards, U.K.) and Petford Group (Dudley, U.K.), the material underwent rigorous testing, proving that the hybrid structure combines the lightweight properties of composites with the stiffness and strength of steel. Composites can also be engineered to absorb energy effectively during impact, and when paired with steel, helps maintain the instrument panel’s structural integrity.
