Beneath the sun-drenched skies of 1968, Ford and Shelby unleashed a machine that would forever redefine open-air exhilaration, the GT500KR Convertible for sale. More than a car, it became a symphony of roaring V8s, sculpted steel, and wind-whipped freedom, capturing the essence of summer driving in its purest form.
Today, Revology Cars reignites this legacy, blending the GT500KR’s iconic design with cutting-edge engineering to create a modern masterpiece that honors its heritage while dominating contemporary roads.
Summer is about sensation, the sun on your shoulders, the growl of an engine, the blur of asphalt beneath you. The GT500KR Convertible delivers all this, whether in its original form or through Revology’s superior engineered revival. For those who crave the golden-era charisma of Shelby’s finest but refuse to compromise on modern performance, this convertible isn’t just the best summer ride, it’s the only one that matters.
The Birth of Open-Air Performance Excellence
The year 1968 marked a revolutionary moment in automotive history when Shelby introduced its first-ever convertible variant of the high-performance Mustang lineup.
This groundbreaking decision came at a time when the muscle car wars were reaching their peak, and Ford recognized that summer driving enthusiasts demanded both raw power and open-air freedom. The GT500KR Convertible emerged as a mid-year introduction, representing Ford’s most ambitious attempt to create the ultimate summer performance vehicle.
The timing could not have been more perfect for summer enthusiasts. Ford had completely redesigned the Mustang platform in 1967 to accommodate both small and big block engines, creating the foundation for what would become the most powerful and luxurious Mustang ever produced. This structural change is what makes the 1967 fastback unique in the Mustang lineup .
By 1968, the engineering team had perfected the balance between performance and comfort, making the convertible variant not just possible, but extraordinary for summer driving experiences.
The “KR” designation, standing for “King of the Road,” was not merely marketing hyperbole but a genuine reflection of the car’s capabilities. This was the first time Shelby American offered customers the opportunity to experience their legendary performance in an open-top configuration, forever changing how enthusiasts would experience summer driving. The convertible represented the evolution of the Shelby philosophy from pure track-focused machines to vehicles that could deliver both devastating performance and luxurious summer comfort.
Sculptural Masterpiece Meets Summer Freedom
The 1968 Shelby GT500KR Convertible exterior design perfectly balances aggressive performance aesthetics with the elegant proportions needed for open-top summer cruising.
The distinctive four-piece fiberglass front fascia marked a significant departure from the previous year’s design, offering improved quality control and more consistent panel gaps that enhanced the car’s sophisticated appearance. This attention to detail becomes particularly important in a convertible, where every line and surface is more visible and scrutinized.
The functional hood scoops and air vents serve dual purposes, both feeding the hungry Cobra Jet engine below and creating an unmistakably purposeful appearance that announces the car’s performance intentions.
These design elements take on added significance in summer driving, where the functional aspects of cooling become critical for sustained performance. The aggressive front grille with integrated rectangular fog lights creates a menacing face that perfectly complements the car’s performance capabilities while maintaining the refined elegance expected of a premium convertible.
The rear treatment features the iconic sequential taillights that became a signature element of the Shelby design language. These flowing light patterns create a distinctive visual signature during summer evening drives, adding an element of theater to every journey. The fiberglass rear spoiler and quarter panel scoops complete the aggressive stance while serving functional purposes in managing airflow around the vehicle at speed.
The convertible configuration itself represents the pinnacle of summer automotive design. The power-operated soft top can be lowered to reveal the car’s beautiful interior architecture while transforming the driving experience into something truly special.
The structural modifications required for the convertible body style, including the addition of a padded roll hoop behind the seats, actually enhance the car’s visual appeal while providing necessary safety protection.
Cockpit of the King

Stepping inside the 1968 Shelby GT500KR Convertible reveals an interior environment meticulously crafted for the ultimate summer driving experience. The front bucket seats, trimmed in premium materials, provide the lateral support needed for spirited driving while offering the comfort required for extended summer road trips. The woodgrain trim accents throughout the cabin create an atmosphere of refined luxury that elevates the convertible experience beyond mere transportation.
The dashboard layout centers around the driver with its comprehensive instrument cluster featuring a 140-mph speedometer and 8,000-rpm tachometer, providing immediate visual feedback about the car’s performance capabilities.
The additional Stewart-Warner gauges for oil pressure and amperage ensure that drivers can monitor the car’s vital signs during demanding summer driving conditions. This attention to instrumentation reflects the car’s serious performance intentions while maintaining the sophisticated presentation expected in a luxury convertible.
The center console houses the period-correct push-button radio and various controls, all finished with the same attention to detail found throughout the cabin.
The woodgrain-trimmed steering wheel provides an elegant interface between driver and machine, while the signature Carroll Shelby nameplate on the glovebox door serves as a constant reminder of the car’s pedigree. The roll bar, while serving safety functions, also adds to the car’s sporty aesthetic and reinforces its performance heritage.
With the top down, the interior becomes an extension of the summer environment, allowing occupants to fully experience the sights, sounds, and sensations of open-air motoring. The quality of materials and construction ensures that the cabin remains refined and comfortable even after years of summer use, making every drive a premium experience.
Unleashed Power Under Summer Skies
The heart of the 1968 Shelby GT500KR Convertible lies in its legendary 428 cubic inch Cobra Jet V8 engine, which delivers the kind of power that transforms summer driving from routine transportation into an adrenaline-fueled experience. Ford conservatively rated this powerplant at 335 horsepower, but automotive experts and enthusiasts have long recognized that the actual output approached 400 horsepower with 440 pound-feet of torque. This underrating was primarily done for insurance purposes, allowing more buyers to access this incredible performance.
The 428 Cobra Jet represented a significant advancement over the previous Police Interceptor engine, featuring improved breathing heads, larger exhaust manifolds, and a ram-air induction system that became particularly effective during spirited summer driving.
Moreover, the Engine’s massive torque output provides effortless acceleration that makes highway merging and passing maneuvers both safe and exhilarating. The distinctive sound of the V8 through the dual exhaust system creates an auditory experience that perfectly complements the visual and sensory elements of convertible driving.
The engine’s characteristics make it particularly well-suited for summer convertible duty. The substantial low-end torque means the car pulls strongly from idle, making city driving pleasant and relaxed when desired.
At the same time, the engine’s high-rpm capabilities allow for thrilling performance when the situation calls for it. The ram-air system works most effectively at highway speeds, providing additional power just when convertible drivers want to experience the full potential of open-road summer driving.
Performance figures for the GT500KR Convertible demonstrate its capabilities with 0-60 mph times around 6.8 seconds and quarter-mile runs in the low 14-second range. These numbers place it among the elite performance cars of its era, while the convertible configuration adds the sensory dimension that makes every acceleration run a multi-dimensional experience. The combination of visual drama, auditory excitement, and physical sensation creates an addictive driving experience that few other vehicles can match.
Summer-Ready Engineering and Equipment
The 1968 Shelby GT500KR Convertible came equipped with a comprehensive array of features designed to enhance both performance and comfort during demanding summer driving conditions. The heavy-duty suspension system featured upgraded coil springs at the front and leaf springs at the rear, along with enhanced sway bars that provided the handling precision needed for spirited summer driving while maintaining ride quality for long-distance comfort.
This suspension tuning struck the perfect balance between performance capability and summer touring comfort.
The braking system featured power-assisted front disc brakes that provided reliable stopping power even during extended summer driving sessions. This was particularly important given the car’s substantial performance capabilities and the likelihood that owners would exercise those capabilities during summer road trips and weekend drives.
The rear drum brakes, while reflecting the technology of the era, were properly sized for the car’s weight and performance envelope.
Power steering came standard on the GT500KR Convertible, making low-speed maneuvering effortless while maintaining proper road feel at highway speeds. This feature becomes particularly valuable during summer driving when parking lot navigation and urban driving scenarios are common.
The three-speed automatic transmission or the optional four-speed manual both provided appropriate gearing for the engine’s power characteristics while offering different driving experiences to suit various preferences.
The Traction-Lok differential helped manage the engine’s substantial torque output, providing improved traction during acceleration while reducing tire wear during normal driving. This feature proves particularly valuable during summer driving when road surfaces can vary significantly and traction conditions may change rapidly. The combination of these mechanical systems created a convertible that could deliver both exhilarating performance and reliable daily driving capability throughout the summer months.
Rarity That Amplifies Summer Magic
The exclusivity of the 1968 Shelby GT500KR Convertible significantly enhances its appeal as the ultimate summer driving machine. With only 517 convertibles produced during the model year, encountering another GT500KR Convertible during summer drives remains an extremely rare occurrence. This scarcity creates a sense of occasion around every drive, transforming routine summer journeys into special events that celebrate automotive excellence and individual taste.
The limited production numbers resulted from several factors, including the mid-year introduction timing and the specialized nature of the Shelby conversion process. Each convertible required additional structural modifications and specialized components that limited production capacity while ensuring quality construction.
The combination of the new Cobra Jet engine and the convertible body style created a particularly desirable package that attracted serious performance enthusiasts who appreciated both power and open-air driving pleasure.
The rarity factor becomes particularly meaningful during summer car shows, cruise-ins, and enthusiast gatherings where the GT500KR Convertible typically draws significant attention and admiration. The combination of its distinctive styling, legendary performance, and extreme scarcity creates a perfect storm of desirability that few other vehicles can match. Owners often report that their cars serve as conversation starters and focal points during summer automotive events.
This exclusivity also contributes to the car’s investment potential, as serious collectors recognize that genuine 1968 GT500KR Convertibles represent some of the most significant and desirable American muscle cars ever produced. The combination of limited production, legendary performance, and iconic status ensures that well-preserved examples continue to appreciate in value while providing their owners with incomparable summer driving experiences.
