The 2016 570S went on sale in December.
The new dealerships are McLaren Bergen County in South Ramsey, New Jersey; McLaren Boston in Norwell, Massachusetts; McLaren Houston in Houston, Texas and McLaren Palm Beach in West Palm Beach, Florida.
"Each joins us with a wealth of experience in their local markets and we look forward to having them support the brand during this period of considerable sales growth," said Tony Joseph, president of McLaren Automotive North America, in a statement on Wednesday.
The new dealerships offer sales and aftersales services for all McLaren models.
The new showrooms will also feature models from the McLaren Super Series range, including the 2016 McLaren 650S coupe and convertible.
There are now 22 McLaren dealerships in North America.
Edmunds says: Demand for these high-end cars is growing, so car shoppers in these key markets will appreciate the arrival of new McLaren dealerships.
