Tesla’s Semi truck, despite its initial hype and pre-orders from major corporations like Pepsi and UPS, has underperformed expectations. Only 36 units have been delivered to Pepsi, while Tesla has prioritized using the trucks for company use. Other companies, frustrated by the delays, have turned to competitors like Freightliner. Tesla has cited battery constraints and production issues as reasons for the setbacks, but has promised increased production in 2024. The company is now expanding its Giga Nevada factory to build Semi trucks, and future European deliveries will come from Giga Berlin.
