In 2008, Tesla released their first-ever vehicle, the Roadster, aimed at showcasing how an electric car could outperform traditional gasoline-powered vehicles in terms of speed and affordability. While not the most cost-effective car, the Roadster made a significant statement. Additionally, the Roadster was groundbreaking as it was the first electric car to use lithium-ion battery cells, a technology now commonly used in Tesla vehicles, smartphones, and laptops.
