Plymouth-based Gibbs Technologies has awarded a $1-million, six-month manufacturing development contract to Saleen Inc. to support the launch of the company’s high-speed amphibious vehicles in North America.

Manufacturing design and engineering work for the Gibbs program will take place at Saleen’s development center at 1225 East Maple Road in Troy, according to Gibbs president and CEO Neil Jenkins.

Gibbs plans to introduce two high-speed amphibious vehicles in the United States in late 2009 and early 2010 -- a sporty car and an all-terrain vehicle.

The Gibbs Aquada is a vehicle that combines the handling of a sports car with an ability to travel up to 40 mph or more on water and 110 mph on land. The company’s all-terrain vehicle achieves speeds of up to 40 mph on both land and water.

Jenkins said Saleen also will be incorporating several new features into the design of the Gibbs Aquada.

Gibbs Technologies has operated from a temporary headquarters facility in Plymouth, for the past eight months. Jenkins said the company plans to announce the location of a North American research-and-development center and corporate headquarters in July.

Gibbs also expects to fill 30 engineering, purchasing, marketing and administrative positions for its North American operations before the end of the year.

The company is the world’s leading developer of HSA vehicles for consumer, commercial and military use. Additional information about Gibbs, its technology and amphibians is available on the Internet at www.gibbstech.com.
