The automotive world recently turned its focus to South Africa, where the magnificent BMW X3 was honoured with the prestigious 2025 South African Car of the Year award. This is a monumental achievement, not just for BMW, but for the entire local automotive manufacturing sector. And we’re immensely proud to announce that Isowall stands as a vital and deeply integrated partner in this incredible success story.

A Local Victory with Global Impact

The BMW X3 is a globally recognized vehicle, a symbol of German engineering and innovation. But what makes this particular win even more special for us, and for South Africa, is the fact that the BMW X3 Plug-in Hybrid Electric Vehicle (PHEV) is produced exclusively here in South Africa, in Rosslyn, Pretoria. These world-class vehicles are then exported to markets all around the globe.

Isowall’s Crucial Role: 22 Parts in each vehicle and Counting

Our partnership with BMW on the X3 project is deeply rooted. Isowall has been a key player in the supply chain for BMW and the rest of the Automotive sector in South Africa for over 2 decades, contributing no less than 22 Expanded Polypropylene (EPP) parts for the current BMW X3 model. These aren’t just any components, they are elements that contribute to the vehicle’s structural integrity, performance, and overall quality. From interior components to specialized exterior bumper absorbers, each part we provide is designed and manufactured to the highest standards, ensuring the X3’s superior ride and longevity.

Isowall Automotive is approved partner of JSP International, the world leader in the EPP sector with the brand name ARPRO which is used to produce EPP parts by Isowall Group. This partnership allows Isowall access to the latest innovations related to the Automotive sector worldwide.

The Hallmark of Quality: A 0 PPM Achievement

This level of involvement demands, and receives, nothing less than perfection from our team. We operate with an unwavering commitment to quality that is truly world-class. Evidence of this dedication is reflected in our remarkable 0 ppm (parts per million) overall status for the parts we supply to BMW. For those unfamiliar, 0 ppm means that for every million parts we deliver, not a single one is found to be defective. This benchmark of quality underscores our position as a reliable and high-performing supplier in the competitive automotive landscape.

Dedicated Team, Exceptional Results

Achieving and maintaining a 0-ppm status doesn’t happen by chance. It’s the direct result of the collective effort, unwavering dedication, and profound commitment of every single member of The Isowall Group’s Automotive team. Their commitment to excellence ensures that every part leaving our facility meets the stringent standards     set by BMW, a company renowned globally for its pursuit of perfection.

A Shared Triumph and Future Outlook

We extend our sincerest gratitude to each, and every team member involved in the manufacturing process for the BMW X3 project. Your hard work, passion, and relentless pursuit of perfection have not only contributed to a truly exceptional vehicle but have also cemented Isowall’ s reputation as a top-tier supplier in the highly competitive automotive industry.

This “Car of the Year” award for the BMW X3 is a shared triumph. It’s a testament to BMW’s vision and engineering, and it’s also a powerful affirmation of the quality and reliability that Isowall consistently delivers. We congratulate BMW on this outstanding achievement and look forward to continuing our successful partnership in building world-class vehicles, right here from sunny South Africa.
