When Ford introduced the Mustang in April 1964, it became an overnight sales success and cultural phenomenon in North America. Eager to capitalize on this success globally, Ford looked toward Europe—specifically West Germany. The country was home to a massive population of U.S. military personnel stationed at various bases, representing a hungry market of young American buyers with disposable income. Ford also saw strong potential among German civilian enthusiasts who favored sporty, compact coupes.

However, Ford’s global expansion plans hit an immediate brick wall at the West German patent office.

The Trademark Roadblock: Krupp and Kreidler

Ford discovered that the name "Mustang" was legally locked down in West Germany by two different entities:

1. Krupp: The massive industrial conglomerate held the trademark for the name "Mustang," which they used on a line of heavy-duty commercial trucks and dump trucks.
2. Kreidler: A well-known German manufacturer of small-displacement motorcycles and mopeds, which also utilized the "Mustang" moniker for a popular lightweight bike.

Ford attempted to negotiate a buyout. Krupp reportedly offered to sell the rights to the name for approximately $10,000 USD at the time (equivalent to roughly $95,000 today). In an era where Ford was spending millions on marketing, this was a relatively minor sum. However, Ford executives—legendarily stubborn on principle—flatly refused to pay a competitor for a name they believed they owned.

Enter the T-5 Project

Refusing to yield to Krupp, Ford looked inward for a solution. They decided to rename the vehicle specifically for the West German market.

They turned to the car's original internal development shorthand. In the early 1960s, the experimental program that eventually birthed the pony car was known internally at Dearborn as the "T-5 Project".

Because vehicles exported to West Germany could not bear the "Mustang" name anywhere on their bodywork, interior, or documentation, Ford had to initiate a meticulous "sterilization" and re-badging process.

Anatomy of a T-5: What Changed?

Transforming a Mustang into a T-5 required extensive alterations at the assembly plants (primarily Dearborn and Metuchen) before the cars were shipped across the Atlantic.

• Exterior Badging: The running-horse-and-tribar chrome emblems on the front fenders were deleted. In their place, Ford installed unique, elongated chrome scripts reading "T-5".
• The Grille: The iconic center grille ornament featuring the running horse inside a corral remained, but the horizontal chrome "bars" extending from the corral were omitted or altered in certain early variations.
• Rear Gas Cap: The standard rear gas cap with the "Mustang" text and pony logo was replaced with a plain, sterile chrome cap, or later, a cap featuring a unique T-5 emblem.
• Interior Details: The steering wheel horn button, which normally featured the Mustang text, was swapped for a clean version bearing the T-5 logo. On the passenger side dash, the "Mustang" script emblem was deleted entirely.
• Documentation: All owner’s manuals, warranty booklets, invoices, and service literature were printed with the "T-5" designation. Mechanically, however, the cars were identical to their domestic siblings, sharing the same engines (200 ci inline-6, 289 ci V8s), transmissions, and suspension setups.

I am getting tired of all of the low effort bot posts, so I thought why not add some real content.

The 1965 Shelby GT350R Prototype, once driven by Ken Miles, sold for $3.85 million at Mecum Indy 2020. link

On Valentine’s Day, February 14, 1965, Ken Miles drove chassis 5R002 in its first sanctioned competitive event at the Green Valley Raceway near Dallas, Texas. It won the race, marking the first-ever victory for a Shelby Mustang

During the race, Miles pushed the prototype over a rise, launching the car completely into the air. A photographer captured the Mustang frozen mid-flight with all four wheels entirely off the ground. The striking image earned the car its permanent moniker: "The Flying Mustang."

As the very first R-Model built (one of only two prototypes alongside 5R001), 5R002 served as Carroll Shelby’s factory engineering mule. It was the rolling testbed used to develop components and ideas that were later implemented into the 34 customer R-models built for the 1965 SCCA season. It was also the exact vehicle presented to the FIA for homologation

Built to race

The car was built from an unfinished Wimbledon White "K-Code" fastback shipped from Ford. Shelby American stripped the vehicle down to bare metal for extreme weight reduction and added high-performance racing components:

• Engine**:** A modified 289 cubic-inch Hi-Po V8 featuring a high-rise aluminum manifold, a massive 715-cfm Holley four-barrel carburetor, and open side-exit exhaust. It produced between 306 and 350 horsepower.
• Weight Reduction**:** The interior was completely gutted to a single racing seat and a full roll cage. The steel hood was swapped for lightweight fiberglass, and the side glass was replaced with Plexiglas.
• Cooling & Performance**:** It featured an advanced external oil cooler, an extra-capacity radiator, and specialized cooling ducts funneled into the front and rear brakes.

In March 1966, Shelby American sold the test car "as-is" to Ford Performance engineer Bill Clawson for $4,000. After experiencing a couple of engine failures during subsequent privateer racing, Clawson utilized his Ford connections to secure a full racing-spec Ford GT40 experimental "XE" engine, which remained with the car.

The vehicle traded hands multiple times and was raced extensively in the Southwest SCCA division and the Mexican Trans-Am series. By the 1970s, it was coated in gray primer and left sitting in a yard in Mexico. It was eventually rediscovered in 1989 and spent 14 years on display in its "as-found" condition at the Shelby American Museum in Boulder, Colorado.

In 2010, dedicated Shelby collector John Atzbach purchased the car and commissioned a meticulous, four-year restoration to return 5R002 exactly to its February 1965 Green Valley racing configuration. Carscoops

*The Auction Record:* In July 2020, at the Mecum Auctions event in Indianapolis, the Ken Miles Prototype sold for *$3.85 million*. This historic sale shattered the previous record held by Steve McQueen's original 1968 Bullitt Mustang ($3.74 million), making it the most valuable Ford Mustang in history at that time.
