Volkswagen continued the trend of offering special editions of its popular Beetle by introducing the Sports Bug in 1973. It was a 1973 Super Beetle equipped with Recaro bucket seats, a simulated-leather sports steering wheel, oversized sports-type radial tires on oversized Porsche 914 rims, a sports-tuned transmission, and an upgraded suspension. The Sports Bug was available in a Marathon Metallic blue and Saturn Yellow colors with special exterior stripping and Black trim. The Super Beetle was also available for 1972. It came with larger brakes, an upgraded suspension, and twice the luggage space as the standard model. The standard Beetle was equipped with the 1600 four-cylinder, air-cooled engine that generated 58 horsepower, as well as a dual braking system, a four-wheel independent suspension, and a flow-through ventilation system. In addition, standard features for the Beetle included seat belts for the driver and passengers, two-speed windshield wipers with a pneumatic washer system, swiveling sun visors, coat hooks, assist straps, folding rear seats, and luggage space under the front hood and in a three-foot carpeted compartment behind the rear seats. A convertible top was optional.
