Reduced Complexity, Increased Sustainability, and Appealing Design

Many of the new components are designed and manufactured from materials from the same chemical product family. Bonded and welded components made from different materials are a challenge in mechanical recycling. For this reason, the designers created as many components as possible from a single material. This principle of simplicity was also implemented during production. With the driver and front passenger doors being identical, this saves on pressing tools and reduces complexity. The same applies to all wheel arches and bumpers. The oli concept car attempts to prove that sustainability and an appealing design are not contradictory.

Co-Creation as a Key to New Solutions

The automotive manufacturer Citroën worked closely with BASF during development and design. Innovative solutions from the chemical company played a vital role in this co-creation endeavor. In addition to its product and engineering expertise, BASF was also able to contribute its design expertise through the Creation Center. “This is where the project was born,” said Alex Horisberger, manager Industrial Design at BASF. “On a visit to the creative studio at Citroën, we were able to convince their designers with our materials and trend analyses. Working on the same level with Citroën’s interior and exterior designers was a personal highlight for me.”

Laurence Hansen, Citroën Product & Strategy director, sees the collaboration in a similar light. “The collaboration with BASF was a key factor in the design of oli and in developing an electric vehicle that’s as fun and efficient as possible for the near future. The innovative electric car runs counter to the trend toward increasingly heavier and more complex vehicles, instead focusing on ease and simplicity. It demonstrates how to keep environmental impact to a minimum, while bringing back the fun of a functional, electric vehicle,” Hansen said.

Wide Range of Solutions for an Innovative Car Concept

Another high-performance plastic from BASF can be found in the rear armrests and the interior floor. Infinergy®, an expanded thermoplastic polyurethane (TPU), is also used in running shoes and sports flooring. In oli, the material provides a pleasant yet stable surface in armrests and floors. Additionally, a special coating is applied to ensure an extra-long life span. The water-based NovaCoat-P coating is ideal for protecting soft substrates against abrasion, UV radiation, dirt, and chemicals. And because the flooring is waterproof, it can be easily cleaned with water. 

The weight of the vehicle exterior was also considerably reduced, while at the same time increasing stability and durability. The hood, roof, and trunk are made of panels combining the Elastoflex® polyurethane system and the Elastocoat® spray paint system. Thanks to the honeycomb sandwich structure, these panels are so stable that you can even stand on them. Used for coating the car body, R-M® AGILIS® is another BASF product that provides greater sustainability. The water-based coating has a very low content of volatile organic compounds. BASF CathoGuard® 800 electrocoat, which protects the battery housing from corrosion, contributes to further resource savings. It stands out for its high performance and eco-friendliness as it is tin/HAPs-free and with low solvent content.
