Hyundai is getting serious about building a ‘walking car’ with four legs Share this story Hyundai Who needs an Apple car when you’ve got one with four legs? Hyundai, which recently acquired a controlling stake in robot maker Boston Dynamics, rolled out a new version of its four-legged “walking car” concept that it first unveiled in 2019. Hyundai is calling it TIGER, which stands for “Transforming Intelligent Ground Excursion Robot.” It’s the second vehicle to come out of the automaker’s Ultimate Mobility Vehicles studio in Silicon Valley, and the first designed to be fully autonomous, with no space for drivers or passengers. It’s like a real-life Transformer, but without the “bent on world domination” vibe.
