The Jaguar E-Type's combination of good looks, high performance, and competitive pricing established the marque as an icon of 1960s motoring. More than 70,000 E-Types were sold. In March 2008, the Jaguar E-Type ranked first in a The Daily Telegraph online list of the world's "100 most beautiful cars" of all time. And In 2004, Sports Car International magazine placed the E-Type at number one on their list of Top Sports Cars of the 1960s.
The E-Type was initially designed and shown to the public as a rear-wheel drive grand tourer in two-seater coupé form (FHC or Fixed Head Coupé) and as a two-seater convertible (OTS or Open Two Seater). A "2+2" four-seater version of the coupé, with a lengthened wheelbase, was released several years later.
Later model updates of the E-Type were officially designated "Series 2" and "Series 3", and over time the earlier cars have come to be referred to as, sensibly, "Series 1" and "Series 1½".
