Another thing about Toyota R&D, they have regional design houses, with the aim to “localized” parts design as much as possible, even the smallest design (engineering) details.
For example, the inside ribs of a Hilux’s wheels in Brazil is about 5mm thicker than the ones in Thailand, so they can withstand 12G, instead 10G, because they did a survey of Brazil potholes, found out they are 20% bigger compared to a Thailand pothole.
Vietnam tires have tickers sidewalls, because people on Hanoi like to climb over curbs. South Africa’s absorbers are 2mm thicker, because people less likely to brake when they see a rock. Air intakes for tropical countries are placed 15mm higher, because there have more floods. Tiny changes which are easily managed at parts manufacturing level, but have significant impact in reducing failure rate.
