However, some key milestones in solar car development include:
* 1950s: Early experimental vehicles were built using solar cells, but they were very inefficient and had limited range.
* 1960s: The General Motors Sunraycer was a landmark car, winning the first World Solar Challenge in 1987. This demonstrated the viability of solar-powered cars for long distances.
* 1980s: The World Solar Challenge was founded, prompting significant advancements in solar car technology.
While it's hard to pinpoint the absolute first, these examples showcase the early progress in developing solar-powered vehicles.
