Only about 619 of them were ever built, and the racing driver they were named after had left the brand before the model year was over. The 1968 Mercury Cougar XR7-G began as a tribute to Dan Gurney’s Trans-Am program and ended as a one-year-only special with no factory racing effort left to celebrate. What buyers actually got for their money is stranger than the story behind it. Read on to find out what made this Cougar different.
Some special editions are built to celebrate a victory. This one was built to celebrate a racing program that was already being dismantled. The Mercury Cougar XR7-G arrived as a mid-1967 tribute to Dan Gurney’s Trans-Am effort, and by the time 1968 production was underway, Lincoln-Mercury had withdrawn from factory Trans-Am racing entirely, leaving the division selling a car named after a driver who was no longer campaigning under its banner. The project had also been handed to Shelby Automotive at precisely the moment Carroll Shelby was losing operational control of that company. What did buyers actually receive for their money in this strange, short-lived footnote?
An Expensive Package Built Almost Entirely on Style
The XR7-G package added $823.35 to an already well-equipped XR-7, pushing the total to just over $4,055 at a time when a nicely optioned full-size sedan cost considerably less. What that premium bought was overwhelmingly cosmetic. Buyers received a distinctive fiberglass hood scoop, hood pins, unique interior trim with a numbered dash plaque, driving lights mounted in the grille, a bullet-shaped Talbot-style outside mirror, and specific badging. Required equipment included power steering and an AM radio. The suspension, brakes, and drivetrain were whatever the buyer separately ordered, which is the detail that makes the XR7-G genuinely unusual among special editions.

Named for a Driver Who Was Already Gone
Dan Gurney’s involvement was real but brief. He was a factory driver for Mercury’s Trans-Am program, and the G in the name is his initial, applied with his cooperation to a package meant to trade on his credibility with performance buyers. Then Lincoln-Mercury stepped away from the series for 1968, which removed the entire competitive justification for the car while the special edition was still on dealer lots. It is a rare case of a tribute car outliving the thing it was paying tribute to, and it happened inside a single model year.
What Shelby Automotive Actually Did to Them
The conversion work went to Shelby Automotive, with the actual assembly handled through the A.O. Smith operation in Michigan that was also building Shelby Mustangs at the time. That connection is why XR7-G cars are often mentioned in the same breath as GT500s, and it is also why the quality of the fiberglass and trim work tends to be comparable. Cars were shipped from Mercury’s Dearborn assembly plant, modified, and then distributed. It was a straightforward contract job at a moment when Shelby’s own organization was being absorbed into Ford’s broader structure.
An Engine Menu That Changed Everything
Under the hood, the XR7-G could be almost anything. Buyers could specify a modest 302 V8, step up to the 390 GT, or go all the way to the 428 Cobra Jet rated at 335 horsepower, a figure that was famously conservative for that engine. A small number of cars received the 427. The practical consequence is that two XR7-Gs can sit side by side wearing identical badging, scoops, and mirrors while delivering entirely different driving experiences, and the value gap between a 302 car and a documented Cobra Jet car is enormous. Verifying the engine is the first thing any serious buyer does.
Hertz Took a Third of the Production Run
Production landed somewhere around 619 to 622 cars depending on which registry you consult, and the distribution of those cars is the part that surprises people. Roughly 188 to 200 of them went directly into Hertz’s Rent-a-Racer fleet rather than to retail customers, echoing the arrangement Hertz had with Shelby Mustangs. That means something close to a third of the entire XR7-G run spent its first chapter as a rental car, driven by people with no long-term interest in its condition, which is not a promising start for a survival rate.
The Sunroof and the Other Small Variations
Within that already tiny population, the variations multiply quickly. Roughly 440 of them left the line with the optional sunroof, including every single Hertz car, which turns the usual rarity logic upside down – it is the 180-odd cars with a solid roof that are the harder find today. Add transmission choices, axle ratios, interior colors, and the wide engine spread, and the practical result is that nearly every surviving XR7-G is at least slightly different from every other one. For collectors this is either the appeal or the frustration, depending on how badly they want a specific combination.
How the XR7-G Compared to a GT500
The inevitable comparison is to the Shelby GT500 that shared assembly space. The GT500 was a Mustang, lighter and more overtly aggressive, aimed squarely at buyers who wanted their performance visible. The Cougar was Mercury’s more sophisticated interpretation of the same platform, with a longer wheelbase, better sound insulation, hidden headlights, and sequential taillights. An XR7-G with a Cobra Jet delivers similar straight-line capability wrapped in a considerably more civilized package, which is a proposition that has aged extremely well.
Why 619 Cars Suddenly Matters
For decades the XR7-G was an obscure footnote, cheaper than an equivalent Shelby and largely ignored by the mainstream market. That has changed. Collectors have had time to work out exactly how few were built, how many went to rental fleets, and how thoroughly the survivors have been scattered. A documented, correctly optioned XR7-G is now a genuinely difficult car to find, and the fact that its namesake had already moved on before the cars finished selling has become part of the appeal rather than an embarrassment.
What to Look For on a Survivor
Evaluating one starts with the details the package actually consisted of. The numbered dash plaque, the correct hood scoop and pins, the Talbot-style mirror, and the grille-mounted driving lights are all reproducible, so their presence proves less than their absence disproves. What matters more is the engine and its documentation, since the spread between a 302 car and a verified 428 Cobra Jet is the single largest variable in the car’s value. Rental fleet history is worth tracing too, given how many went to Hertz, and a car with a continuous retail ownership record from new is meaningfully scarcer than the raw production figure suggests.
