Guldstrand (United States)

Guldstrand Specialty Automobiles was an American automotive manufacturer based in Culver City, California. Founded by Dick Guldstrand, a noted Corvette racer, the company specialized in creating enhanced versions of Chevrolet streetcars. Guldstrand's expertise in racing informed his approach to automobile design, leading to the production of vehicles that combined performance with distinctive modifications.

In 1985, Guldstrand introduced the Grand Sport 80 package, which featured a powerful 355 horsepower engine and achieved a top speed of 171 mph (275 km/h). This model was produced in limited quantities, with approximately four to five units sold annually until its discontinuation in 1990.

Following the Grand Sport 80, Guldstrand launched the Grand Sport 90 in 1994, which was based on the ZR-1 Corvette. This model showcased a unique design with rounded bodywork created by Steve Winter and was priced starting at $134,500. The Grand Sport 90 offered two engine options: a 480 horsepower petrol engine and a 400 horsepower variant that utilized compressed natural gas, although the latter was only tested and never installed in a production vehicle. The suspension of the Grand Sport 90 was significantly reworked to enhance handling capabilities. By 1999, around a dozen units of the ZR-1-based GS-90 had been sold.

In 1997, Guldstrand also offered a convertible conversion known as the Guldstrand Nassau, which was designed to be built on customer-supplied non-ZR-1 Corvettes. This expansion of offerings reflected Guldstrand's commitment to providing customized performance vehicles tailored to the preferences of individual customers.
