OK. It is a concept. That was developed in Europe. It is 122.8 inches long, 68 inches wide and 71 inches high.

Answer: Lexus.
Explanation from Spiros Fotinos, Head of Lexus Europe, comments: “The Lexus ROV is our response to the growing passion for the outdoors and adventurous spirit of luxury consumers. As a concept, it fuses our desire to also develop lifestyle-oriented products with our ongoing research into new technologies that contribute to carbon neutrality. As well as delivering a concept that is thrilling to drive, it has near zero emissions thanks to its hydrogen powered engine.”
