Previously, Lotus said the Evora 400 would be a 2016 model with a fall on-sale date.
The debut of the highly anticipated Evora 400 "marks the start of a fresh period in Lotus' presence in this vital market," the company said in a statement.
The 400-horsepower Evora flagship debuted at the 2015 Geneva Auto Show, featuring a mid-mounted 3.5-liter V6 engine with a new supercharger. It has a top speed of 186 mph and accelerates from 0 to 60 mph in 4.1 seconds.
Lotus said its North American dealer network now includes four new dealers, including Lotus of West Covina and Lotus of the Desert in Thermal, California, along with locations in Scottsdale, Arizona and Calgary, Alberta. Lotus said it has 47 dealers in North America.
Lotus also announced plans to relocate its U.S. headquarters from Lawrenceville, Georgia to Ann Arbor, Michigan. The headquarters will share a location with Lotus Engineering, Inc. The move is expected to be completed by the end of July.
"This will reaffirm our presence in the North American market by providing improved customer service (and) better technical and consultancy support," Lotus said.
