By the late 1960s, the Ford GT40s were obsolete in international racing. After 1967, sports car prototypes had been limited to the 3.0 litre engine size used in Formula 1 since 1966, and the [[Ford P68]] (also Ford 3L GT or F3L) was a Ford-sponsored attempt to compete in that category with the Cosworth V8 F1 engine.  Since the 1970s, there was growing interest from enthusiasts rather than racers in Ford GT40s that could not be satisfied with the remaining GT40s, even though around 100 had originally been made.  This led to the production of "continuation models" and replicas.

For years{{when|date=August 2024}} Peter Thorp, owner of Safir Engineering, had searched for a GT40 in good condition. Most of the cars had problems, including significant rusting. His company was building and fielding [[Formula 3]] race cars; in addition, it had a {{clarify span|text=Token|reason=What does this word here mean, and why is it capitalized?|date=August 2024}} Formula One car purchased from the [[Ron Dennis]] Company, Rondell Racing. Formula One events in which Safir Engineering competed{{when|date=August 2024}} included [[Brands Hatch]] and [[Silverstone Circuit|Silverstone]]. Safir was also redesigning and exporting [[Range Rover]]s, modifying them to six-wheel drive. Safir had the technical capabilities to rebuild GT40s. Desiring to build new GT40s from scratch, Thorp approached John Willment,{{who|date=August 2024}} partner of [[John Wyer]],{{who|date=August 2024}} for his thoughts. It was soon decided{{by whom|date=August 2024}} that there would be a limited, further run of the GT40. JW Engineering would oversee the build, with Safir doing the work. The continued JW Engineering/Safir Engineering {{clarify span|text=GT40 production|reason=Authorized by whom, or what corporate entity? Who owned the intellectual patent rights to the GT40?  How were they acquired by JW/Safir?|date=August 2024}} would utilize sequential serial numbers starting at the last used serial number. Maintaining the vehicle's Mark nomenclature, the new cars would be referred to as GT40 Mk Vs.

JW Engineering wished to complete the existing GT40 chassis numbers GT40P-1087, 1088 and 1089 prior to the beginning of Safir production; this, however, was very much delayed.

Ford's{{which|date=August 2024}} Len Bailey{{who|date=August 2024}} was hired to inspect the proposed build and engineer any changes to minimize known problems with the car, and upgrade safety to modern standards he thought prudent. While the GT40 chassis was upgraded without making any major changes, Bailey upgraded the front suspension to [[Alan Mann Racing]] specifications, which minimized nose-dive under braking. Zinc coated steel replaced the previous uncoated rust-prone sheet metal. The vulnerable drive donuts were replaced with [[CV joint]]s and the leak-prone rubber gas tanks were replaced with aluminum.

Metal fabricator Tennant Panels supplied the roof structure, and the balance of the chassis was completed by Safir with parts from Adams McCall Engineering. Bill Pink, noted for his electrical experience and the wiring installation of previous GT40s, was brought in. Also, Jim Rose{{who|date=August 2024}} was hired for his experience with working at both Alan Mann and Shelby. After the manufacture of chassis 1120, John Etheridge{{who|date=August 2024}} was hired to manage the MkV GT40 build.

For the most part, the Mk V resembled very closely the Mk I car; as with the '60s production, very few cars were identical.

The first new build, GT40P-1090, had an open-top in place of roof-hinged doors. Most motors were Ford "small block" V8s, fitted with twin-Weber or 4-barrel carburettors. Safir produced five "big block" Mk V GT40s, serial numbers GT40P-1128 to GT40P-1132. These aluminium bodied cars all had easily removable door roof sections.{{why|date=August 2024}} Although most Mk V GT40s were high-performance street cars, some were built solely to race specs. Two road cars, a roadster (GT40P-1133), and a standard configuration (GT40P-1142), were built with lightweights aluminium honeycomb chasses and carbon fiber bodywork.

Several [[kit car]]s and replicas inspired by the Ford GT40 have been built. They are generally intended for assembly in a home workshop or garage. There are two alternatives to the [[kit car]] approach, either [[Continuation car|continuation]] models (exact and licensed replicas true to the original GT40) or [[modernization]]s (replicas with upgraded components, ergonomics & trim for improved usability, drivability, and performance).
* GT40/R Competition, United States: Authentic GT40 built by [[Superformance]] and co-designed with Pathfinder Motorsports. This is the only GT40 continuation licensed by Safir GT40 Spares LLC, the holders of the GT40 trademark.

* Ford GT40 By Everrati: Everatti's GT40 replica uses a Superformance body and is powered by a 700-volt electric architecture, allowing for fast charging. Everrati estimates it delivers {{Convert|800|PS|kW|0|abbr=on}} and {{Convert|590|lbft|Nm|0|abbr=on}} of torque, making it almost twice as powerful as the most powerful version of the original GT40.
