Turkey returns to the WRC for the first time since 2010. The 10th round will be based in the popular international holiday resort of Marmaris, in the south-west of the country, on September 13-16.
The gravel event will feature fast to medium-speed special stages, including a mix of smooth open roads near Marmaris and more demanding rocky mountain passes in Mugla state.
Turkish motorsport federation TOSFED will organise the rally, which will be one of the most compact in WRC history with several stages starting or finishing close to the service park. The speed tests hug the coast in places, guaranteeing dramatic TV images for fans.
WRC manufacturers Toyota, Hyundai and Ford build vehicles in Turkey, which was Europe's fifth largest automotive producer in 2016 with almost 1.5 million vehicles constructed.
The season begins later than in 2017 as Monte-Carlo moves back a week to January 25-28. The second round in Sweden is also seven days later on February 15-18.
Following the seventh round in Italy on June 7-10, there will be a six-week break before the second half of the season begins in Finland on July 26-29.
Great Britain switches from late October and will run three weeks earlier on October 4-7, allowing the event to also count for the British Rally Championship.
Spain swaps with Great Britain to become the final European round and the penultimate event of the season. It reverts to its more traditional slot on October 25-28.
WRC Promoter managing director Oliver Ciesla said the 2018 calendar offered heritage and originality.
"The 2018 season brings an enticing blend of WRC tradition and history, in the form of classic and long-standing rounds such as Sweden, Argentina and Finland, with a welcome return to Turkey," he said.
"Turkey is a hugely important automotive market, in terms of sales and manufacturing. Record sales of almost a million vehicles were recorded in 2016 and the sporting reasons for its reintroduction are matched by a compelling business rationale.
"We offer manufacturers the opportunity to showcase their products in a championship focused on production-based cars, and I'm delighted Turkey's return was unanimously supported by our participating manufacturers," he added.
