The Noble M400 is the top of the line variant of the Noble M12. Introduced in 2004, the M400 was powered by a mid mounted 3.0L twin turbo V6 engine. Widely lauded for its dynamic abilities, the M400 was an incredibly adept car, capable of competing with, and beating, many of the world's most well regarded supercar manufacturers. The M400 was in production until 2007, when Noble sold the production rights to Rossion, who continue to manufacture the car as the Rossion Q1 in the United States.
