On the outside, the Seal 6 carries BYD’s modern design language well, with sleek lines and a purposeful stance. Standard equipment on the Boost includes 17-inch alloys, LED lights, a 12.8-inch touchscreen and vegan leather upholstery, which already feels generous for the price bracket. Practicality & Efficiency One of the Seal 6 Boost’s strengths is its practicality. The estate version has a generous boot, and the saloon’s load space is still competitive. A large fuel tank and efficient hybrid system promise long distances between stops ???? What’s Good Excellent value and equipment level for the money. Strong efficiency and long overall range. Practical interior and usable hybrid system.
