Daimler, Jaguar's ultra-luxury sub-brand, will return to the market after a three-year absence.
A long-wheelbase version of the XJ will wear the Daimler badge. It also will have a price tag that is expected to be well over E100,000, making it Jaguar's most expensive sedan.
Features that distinguish a Daimler from a Jaguar include a different grille plus interior wood and leather fittings normally found in super-luxury models such as Rolls-Royce.
The British carmaker will debut its Daimler at September's IAA in Frankfurt, said Stephen Perrin, Jaguar's global marketing director. The new Daimler goes on sale before the end of 2005.
When Jaguar replaced the XJ three years ago the Daimler nameplate disappeared.
In 1896, Gottlieb Daimler licensed a company in the UK to build Daimler-badged models. The carmaker soon developed its own luxury limousines, which became popular with the British royal family. Jaguar bought the Daimler brand in 1960 and has used it ever since for its most exclusive sedans.
