The 1275 GT Mini Was The Cooper S Of The ‘70s
As the ‘60s were coming to a close, British Leyland hired Ford designer Roy Haynes (responsible for the Ford Cortina MkII) to revamp the Mini for the 1970s. Haynes restyled the entire front end of the British microcar with a boxier snout featuring a fender-to-fender grille section with larger headlights sitting atop a revised front bumper. The restyled model was offered in two trim levels: the Mini Clubman, and the Mini 1275 GT.
Originally slotted to replace the Cooper S, the Mini 1275 GT was produced alongside the Cooper S until 1971. The new GT featured a 1,275 cc four-cylinder and a unique four-synchro close-ratio four-speed manual gearbox—previous Mini transmissions didn’t come equipped with a first gear synchro.
The 1275 GT, although not quite as quick as its Cooper S predecessor, was cheaper to buy and operate compared to the S. The 1275 GT was also the first Mini to receive a tachometer. 10-inch Rostyle alloy wheels fitted over 7.5-inch Cooper S carryover disc brakes came standard.
The original “round-front” 1959 Mini design is a tried and true classic, but the 1275 GT marks a unique point in styling for the cult-followed British “People’s Car.” With a boxier front end, 70s flank graphics, and unique standard equipment, the 1275 GT is a fully-loaded sporting saloon that’s still very much Mini, just with some added flair.
The owner of this 1971 Mini 1275 GT found the car parked unloved on his brother’s work premises at Somerford Mini. Purchased in 2004, the current owner spent thousands of dollars restoring this 1275GT model from the ground up. The Mini specialists at in the UK were hired to carry out the complete restoration.
The car has done less than 10,000 mile since its full restoration, when the original 1,275 cc engine was punched-out to 1,293 cc and rebuilt to a slightly modified specification. The rebuild mimics the BMC “Special Tuning” spec for the Cooper S upgrade that was offered in 1971, which consists of twin 1.25-inch HS2 SU carburetors, Stage One ported and polished head with larger valves, a Kent 276 camshaft, and a lightweight flywheel. The engine was fully balanced and fitted with an electronic ignition system for more reliable start-up, and the original DC generator has been replaced by an AC alternator for additional reliability improvement.
The correct and original four-synchro close-ratio four-speed manual transmission is still in place and was rebuilt alongside the engine. The transmission received all new bearings, seals, and bushings in addition to having any worn gears replaced.
Several body panels were replaced with authentic British Motor Heritage pieces to ensure a proper fit. Once the bodywork was ironed out and perfected, a professional application of its original Bronze Yellow nonmetallic paint was resprayed. New Mini 1275 GT side graphics were applied and all brightwork, bumpers, and trim were installed to a high standard. The correct 10-inch Rostyle sport wheels retain good finish.
The interior was also overhauled with a combination of original trim and Newton Commercial replacement materials. The seat covers, door panels, and headliner are OEM-style pieces sourced from Newton Commercial. The floor is lined with extremely rare new old stock BMC original “veltone” carpeting, and the steering wheel is an original 1275 GT wheel that’s been re-trimmed in black leather.
A modern stereo unit was installed with speakers hidden under the rear seat. All three original instruments are functional and clean, including the 1275 GT tachometer. All switchgear and accessories are correct, clean, and operational.
