Sears XDH-1
The Sears XDH-1 was an experimental electric car built for Sears, Roebuck and Co. by their battery supplier Johnson Controls (Globe Union) in 1977 to celebrate the 10th anniversary of the company's "DieHard" brand of car batteries.
The car was a Fiat 128 Coupe with the engine and fuel system removed. It was equipped with 20 DieHard (12-inch deep cycle marine) batteries in the trunk and back seat area powering a World War II-era 27-horsepower electric aircraft starter motor connected to the front drive-shaft via the factory transmission. The two-seat car had a top speed of about 70 miles per hour with a range of 60-90 miles (at 50 MPH) per charge. The car could be charged at regular 110 and 220-volt outlets, requiring between 6 and 18 hours for a full charge.
The XDH-1 was demonstrated during a nationwide tour in 1977 that included downtown Birmingham, an ascent of Pike's Peak, and speed trials at several racetracks, including the Alabama International Motor Speedway in Talladega on July 31 (67.645 mph, driven by Country music star Marty Robbins). The car is now on display at the International Motorsports Hall of Fame and Museum at the Talladega Superspeedway.
