The new BMW 8 Series Coupe is a revival of a very special boot badge for the brand. In the 1990s, the radical 8 Series was a technological tour de force and, like that car, this new flagship model is a platform for BMW to showcase its tech, luxury and performance credentials to the full. It faces stiff competition from the Mercedes S-Class Coupe and Aston Martin DB11. Find out how it stacks up in our full BMW 8 Series review.
