The Gilbern GT was a 2+2 two-door coupé and Gilbern's first car and was made between 1959 and 1967.
The GT Mk 1 was initially available with either 948 cc Austin-Healey Sprite with an optional Shorrocks supercharger or Coventry Climax 1098 cc engines. The chassis was fabricated from square steel tubing and the front suspension was initially from the Austin A35. The body was a one-piece moulding. Although usually supplied in kit form, the body was provided fully trimmed and painted leaving the purchaser to only complete the mechanical items.
A car with 1600 cc (ex MGA) engine was tested by the British The Motor magazine in 1961 and was found to have a top speed of 94.3 mph (151.8 km/h) and could accelerate from 0-60 mph (97 km/h) in 13.8 seconds. A fuel consumption of 35 miles per imperial gallon (8.1 L/100 km; 29 mpg-US) was recorded. The test car cost £978 including taxes of £251.
