Chelsea tractor was coined by environmentalists to reflect the popularity of four-wheel drive vehicles with middle-class families living in wealthy areas. The use of tractor relates to the original use of vehicles such as the Land Rover™ by farmers in the countryside. Chelsea is a district of London popular with the rich and famous. Its use in the phrase was possibly inspired by the fact that the Chelsea district encompasses Sloane Square, itself the basis of the 1970s term Sloane (Ranger), a derogatory reference to young, upper-class, English women, which puns on Lone Ranger, the title of a popular 1950s TV show.
