The Ultra variant of the SU7 line-up is so quick that it beat not only Tesla's fastest electric car - the Model S Plaid - around Germany's Nurburgring, but also the Rimac Nevera .
Founded in 2010 by Lei Jun and headquartered in Beijing, Xiaomi is best known for its well-priced Android smartphones and other consumer gadgets, including robotic vacuum cleaners and even electric scooters.
In recent years, though, the company has diversified into electric vehicle manufacturing, and so far has produced the SU7 electric sedan and the more recent and equally impressive YU7 SUV, positioning itself as a tech-driven motoring company alongside BYD and Tesla. Xiaomis rapid ascent has been described by analysts as a threat to those companies.
