If you want a glimpse into the future, come to Berlin and walk down Kurfürstendamm, the bustling avenue often described as the city’s Champs-Élysées. At one of the most prominent corners sits a new car showroom unlike any I have ever seen: sleek, elegant, multistoried, with a cafe, design center, showrooms and more. As you enter, you see what looks like a Bugatti or a Ferrari, except more stylish. It’s an EP9, a top-of-the-line racecar that has been sold to a handful of customers for about $3 million each. The company behind it is Nio, one of China’s new carmakers, which is going to take the world by storm.
