Positioned above the Laguna and measuring almost five metres long, 1.8 metres wide and 1.5 metres high, the Latitude has been designed for several markets worldwide.
The Latitude will make its debut at the Moscow Motor Show in Russia prior to it going on sale in Asia, Africa, Australia, Turkey, Gulf, Russia and Mexico.
It may not arrive in the UK, however. A European version will be showcased at the Paris Motor Show in 2010 but the French manufacturer has not revealed if it will be available in the UK.
The large saloon market is small in the UK, and Renault may decide to focus on markets such as its home market in France, where previous saloons have proved popular.
The first images of the Latitude show a distinctive chrome grille and bi-Xenon headlights. Unlike the Vel Setis saloon, which was discontinued in 2009, the Latitude is much more understated in its exterior design.
Renault says the front end mirrors the power of the engines in what is a slightly cryptic clue. However, it does promise a wide range of engines along with a precise chassis.
At the rear, the Latitude features a large boot, LED lighting and a chrome rear strip bearing the Latitude name.
Renault promises a comfortable, silent ride from the model, which is based on the same architecture as the Korean SM5, a joint venture from Renault and Samsung.
Specifications will be announced closer to the launch date, but Renault says it will feature climate control, driver seat massaging, a Bose sound system and a hands-free card.
Full European specifications of the flagship saloon will be unveiled at the Paris Motor Show.
