The Name

• For much of its existence, the vehicle was called the Suburban Carryall, but in 1980 it was rebranded as the Suburban.
  
  

The Doors

• As the Suburban design advanced, more doors were added for convenience. In 1967, a second passenger-side door was added, and starting in 1973, a second driver-side door was added, making it a fully functional four-door vehicle.
  
  

Early Years

• The first Suburbans were military vehicles, with truck frames and bodies mostly made out of wood.
  
  

Third Generation

• The third-generation Suburban was introduced in 1971 and ran for 18 years, making it the longest production run for the vehicle. Chevy did tinker with the engine during that time, making a diesel version available in 1982 and introducing a fuel-injected model in 1986 to improve fuel efficiency.
  
  

Four-Wheel Drive

• Chevrolet introduced four-wheel drive versions of the Suburban in 1957.
