Henrik Fisker is probably best known for his attempt at starting an automaker, but before the days of Fisker Automotive the Danish businessman was working as a car designer and running coachbuilder Fisker Coachbuild. Well, it appears Fisker isn’t finished with the auto world just yet as he’s teamed up with famous Ford tuner Galpin Auto Sports to develop a carbon fiber-bodied car based on the 2015 Ford Mustang and called the Rocket.

Revealed today in full at the 2014 Los Angeles Auto Show, the Rocket is described as the “ultimate American muscle car” and will eventually be available for sale. Interested buyers will have the option of purchasing a car through Galpin’s own dealership or one of several hand-picked locations not only here in the U.S. but across the world. Deliveries of the car are scheduled to commence early next year.

The Rocket’s design is unmistakably inspired by specialty pony cars of the 1960s and early ‘70s, including the 1968 Ford Mustang Shelby GT500 (Fisker's favorite). Anchored by an imposing hexagonal grille crafted from carbon fiber and split with a polished aluminum bar, the Rocket’s lines emanate from the front, through the long hood, over a set of sculptured flared fenders and converge on its integrated rear spoiler.

That spoiler, along with many of the car’s other aero pieces, is fully functional. A front splitter also helps draw out hot air from underneath the car to improve engine cooling, while simultaneously working in conjunction with the rear spoiler, enlarged rear diffuser and side skirts to produce downforce. And those large scoops in the hood are designed to channel air into the engine bay, also helping to keep the car’s engine, a 725-horsepower supercharged 5.0-liter V-8, cool.

Other elements of the design include a custom silver paint finish known as Éminence Grise; independent, fully-adjustable suspension; 21-inch wheels shod with Pirelli P-Zero tires; and powerful Brembo brakes with 15-inch discs up the front.

You might be wondering how this project came about. It turns out Galpin’s ties with Henrik Fisker date back several years. In addition to being a top dealer for the Ford Motor Company [NYSE:F], Galpin is also a major dealer for Aston Martin. Henrik Fisker previously worked as a design for the British sports car brand, helping with the designs of the DB9 and Vantage models, and it was during this time that he first met the team at Galpin.

“Ford’s engineers and [Ford design chief] Moray Callum’s design team did an amazing job with the new Mustang,” Henrik Fisker said at today’s reveal. “So good in fact, I think the design additions and power upgrades we have made to the car help it play in a higher league, against much more expensive supercars.”

Last year’s Galpin Rocket proved to be such a hit that the people behind the 725-horsepower muscle car, Galpin Auto Sports and Henrik Fisker, have followed it up with a convertible version. Called the Galpin Rocket Speedster, the car is on show this weekend at the 2015 Pebble Beach Concours d’Elegance.

Still a concept, the car will likely see some form of limited production in the ensuing year, just like its coupe sibling. In fact, interested buyers can already place an order through Galpin’s own Ford Motor Company [NYSE:F] dealership in Los Angeles or through one of several hand-picked dealers both here in the United States and in other markets.

The Galpin Rocket Speedster features a custom carbon fiber cover that replaces the donor Mustang Convertible’s soft-top roof. You lose the rear seats in the conversion but what you’re left with is something much sportier, whether the roof is up or down.

The design is also said to integrate a number of key aerodynamic elements to help channel airflow. For example, to reduce air turbulence, the cover’s air outlets are equipped with an integrated mesh directly behind the driver and passenger, allowing air to pass smoothly over the redesigned lower rear deck.

“When I worked on the Rocket Speedster project with Beau, the creativity sparks were constantly in the air,” Fisker said at this weekend’s reveal. “When I was designing the speedster cover, I gave it extreme sculpture and dynamic lines that flows with the muscular body of the Rocket and created a new interior graphic to go with it.”

Under the carbon fiber hood of the Galpin Rocket Speedster is the Mustang GT’s familiar 5.0-liter V-8, which has been supercharged to help boost output to a supercar-like 725 horsepower. Other performance upgrades include independent, fully-adjustable suspension; 21-inch wheels shod with Pirelli P-Zero tires; and powerful Brembo brakes with 15-inch discs.

The exterior is finished in a deep metallic red color that’s contrasted by visible polished carbon fiber stripes along the bottom of the car, extending from the imposing hexagonal grille to the rear of the car. Responsible for the body work was GFMI Metalcrafters, based in Fountain Valley, California.

Pricing for the Galpin Rocket coupe started at $109,100, and we’d expect this open-top version to cost substantially more.
