Daihatsu has unveiled the Vision Copen Concept, a larger and more powerful version of its popular kei car, the Copen. Set to make its debut at the 2023 Japan Mobility Show, the Vision Copen is almost as big as Mazda's Miata, measuring 3,835mm in length and 1,694mm in width. Unlike the standard Copen, which is limited in size due to kei car regulations, this concept features a rear-wheel-drive layout, similar to the Mazda MX-5.
