The Sunbeam Tiger was not a new idea; it was a concept that had been well practiced for many years. The Tiger was powered by a high-horsepower American powerplant in a British body. Jack Brabham, who had campaigned Sunbeam Alpine cars with much success in the fall of 1962, suggested a Ford V8 engine should be installed in the Alpine. The work was handled by Carroll Shelby, who selected a 260 cubic-inch Ford Fairlane small-block V8, and installed it in the small engine bay of the Alpine. A prototype car was put on display in April 29, 1963. The car featured a stout anti-sway bar and a transmission that had been modified by hot rodder Doane Spencer. After 40,000 miles of testing, the project was pitched to company head Lord Rootes.
This Tiger Mark I was one of the first 250 examples to roll of the assembly line of contractor Jensen Motors. The car has a removable hardtop and the original engine has been bored and stroked to increase its displacement to 289 cubic-inches. The car now has a top speed of 122 mph and a zero-to-sixty time in just over eight seconds.
The car has been given an extensive restoration that included a complete rebuild of the car's engine and transmission. The car has period-correct black carpets and upholstery, and a dark-blue paint scheme. The car has accumulated only 38,000 miles.
In 2010, this Sunbeam was offered for sale at the Gooding & Company auction held in Scottsdale, Arizona. It was estimated to sell for $50,000 - $75,000 and offered without reserve. As bidding came to a close, the lot had been sold for the sum of $44,000, including buyer's premium.
