How Stellantis and BASF joined forces to reduce the weight, and improve the durability of the 2021 Jeep Grand Cherokee L, without compromising safety performance.
Stellantis, a leading global automaker was looking to reduce the weight of their 2021 Jeep Grand Cherokee L since their traditional solution was made from high strength steel. The aim was to reduce mass of the vehicle and improve durability without compromising safety performance.
The cooperation between BASF, L&L products and Stellantis resulted in a lightweight composite tunnel reinforcement (CTR), which has superior strength to magnesium, aluminium or steel, while upholding safety standards.
The Power of Technology
- The combination of the Continuous Composite Systems™(CCS) pultrusion technology with polyurethane chemistry from BASF was the key to success of the CTR
- By using the CCS pultrusion technology, L&L Products and Stellantis were able to create a new design that reduces the packaging along with mass and uses the surrounding environment on the vehicle to help transition loads to the CTR.
- BASF’s Elastocoat polyurethane chemistry together with continuous glass fibre provided an exceptional strength to weight ratio in comparison to ultra-high strength steel.
- 40% weight reduction compared to the previous version
- A further 20% weight saving on the subsystem
- Total weight savings of 2.08kg per vehicle
- The weight reduction contributes to lower CO2 emissions and better gas milage of the vehicle
