The Oscar Mayer Wienermobile has evolved from Carl Mayer's original 1936 vehicle to the current vehicles seen on the road today. Although gas rationing kept the Wienermobile off the road during World War II, in the 1950s Oscar Mayer and the Gerstenslager Company created several new vehicles using a Dodge chassis or a Willys Jeep chassis. One of these models is on display at the Henry Ford Museum in Dearborn, MI. These Wienermobiles were piloted by "Little Oscar" who would visit stores, schools, orphanages, children's hospitals, and participate in parades and festivals.
In 1969, new Wienermobiles were built upon a Chevrolet motor home chassis and featured Ford Thunderbird taillights. The 1969 vehicle was the first Wienermobile to travel to foreign countries. In 1976 Plastic Products, inc., built a fiberglass and styrofoam model, again on a Chevrolet motor home chassis.
In 1988, Oscar Mayer launched its Hotdogger program, where recent college graduates were hired to drive the Wienermobile through various parts of the nation and abroad. Using a converted Chevrolet van chassis, Stevens Automotive Corporation and noted industrial designer Brooks Stevens built a fleet of six Wienermobiles for the new team of Hotdoggers.
In 1995, the Wienermobile grew in size to 27-feet long and 11-feet high. The most recent version of the Wienermobile, built in 2004, has been updated to include a voice activated GPS navigation device, an audio center with a wireless microphone, and a horn that plays the Wiener Jingle in 21 different genres from Cajun to Rap to Bossa Nova, according to American Eats.
There are seven Wienermobiles in existence. The current Wienermobile sports fourth generation Pontiac Firebird taillights.
