That's not my understanding of how the automotive supplier tiers work, having worked for DuPont, which operated as a Tier 1, Tier 2, and Tier 3 supplier. The tier ranking has to do with the supply chain, not quality. Tier 1 suppliers work directly with OEMs, often providing subassemblies. Tier 2 suppliers provide Tier 1 suppliers. Tier 3 suppliers supply Tier 2 suppliers, often with raw materials. Let's say the subassembly is a power window mechanism. The Tier 2 supplier might provide the brackets, motor or electronic control module. The Tier 3 supplier might be the company supplying the chips for the electronics, or steel for the brackets. In the case of DuPont, as a paint supplier selling directly to OEMs, it was Tier 1. It also sold coatings and polymers to Tier 1 companies, making it a Tier 2 supplier, and a lot of polymers were also sold to Tier 2 suppliers, making it a Tier 3 supplier.

It’s been a very long time since I read such a comprehensive review on a new car. Harkens back perhaps to Car of the 70s. Though they would likely have been more complimentary due to the McLarens Englishness. Great work.
