It was introduced midway through the production year, at the North American International Auto Show at the Detroit Auto Show during January 1977 - along with the Pontiac Sunbird Sport Hatch model. One feature of the Can Am was the Trans Am'sshaker hood scoop as standard equipment. The car was a variation of the Pontiac Le Mans, but powered by the Pontiac 400 rated at . Cars specifically destined for Californian or high-altitude county dealers, featured the Oldsmobile 403 Small Block making. The Can Am package was on Le Mans cars painted Cameo White which were then accessorised in orange, red, and yellow graphics, as well as blacked-out lower panels and window trim. The standard road wheel was a color-matched Rally II with chrome trim rings. Many options were available, including the aluminum "snowflake" wheels offered on the Trans Am, and a steel or glass sunroof. Interior trim color options were the same as the base Le Mans, and included red, black, white, and tan. The number of Can Ams produced has never been accurately determined, but the number most commonly used is 1,377. Complete Le Mans coupes were shipped by Pontiac to Jim Wangers' Motortown which carried out the various Can Am appearance modifications, including those relating to the hood, rear deck spoiler and body decals. According to the Can Am Registry in late 2007, 42 cars feature the Oldsmobile 403 engine, outwardly identified by "6.6 LITRE" decals on the hood shaker. The rest of the cars on the Registry have the Pontiac 400 engine, designated "T/A 6.6" on the hood shaker decals. The Pontiac Historical Service can determine whether a car is a genuine Can Am, and list the options as it was delivered from the factory. When the Can Am was first introduced to the dealers, Pontiac envisioned producing 2,500 units; the response from the buying public was much more than expected and over 5,000 orders were submitted. Unfortunately, the mold used to produce the fiberglass rear spoiler broke, and production at Motortown ended. Pontiac upper management, already worried about losing sales of their Grand Prix models, decided to scrap the project after approximately one half year of production. Road tests commonly quoted the Can Am as having a Pontiac 400, along with a 2.41 rear gear ratio. This was a combination never offered to the public. When built with the Pontiac 400 engine, the Can Am came with the three-speed automatic TH400 and 3.08 rear gears. When built with the Olds 403 engine, the Can Am came with the three speed automatic TH350 and 2.41 rear gears. No four-speed manual transmission cars were produced. Performance tests from 1977 estimated 0- time for the Can Am with the Pontiac engine at about 10 seconds, about the same as the previous year's Le Mans with the 455, and a time of approximately 17 seconds. Regarding production numbers, in an interview with Jim Wangers in 2010 he stated the total number of Can Ams produced was 1133.
