The Renault Fluence is a compact sedan produced by the French automaker Renault. The car was produced until 2016 at the Oyak-Renault plant in Bursa, Turkey. It was produced until the end of 2018 in Santa Isabel, Argentina, for the Latin American market.

On 12 July 2016, Renault unveiled the successor to the Fluence, initially for the market of Europe, the Mégane Sedan IV.

Revealed in August 2009, the Fluence is based on the Renault/Nissan C platform, but it is sized between the compact family saloon C segment, and the upper medium segment.

The Mégane range featured a "three box" notchback sedan variant until the end of 2008, but this was never a big seller and when, at the end of that year, the Mégane III was introduced, there was no notchback version available.

The gap in the range left by the removal of the saloon model from the Franco-Spanish assembled Mégane range was filled by the Fluence in markets such as France, Italy, Belgium, Ireland and - from August 2010, Germany.

The Renault Fluence is also badged as Renault Samsung SM3. The Renault Samsung car was first presented at the Seoul Motor Show in April 2009, and the rebadged Renault Fluence went on sale in November 2009. The model has first been offered with two petrol engines: a 1.6 litre 110 hp (82 kW) and a two-litre 140 hp (104 kW) that can get an optional CVT.

The diesel variant is equipped with a 1.5 litre dCi engine, offered in 85 hp (63 kW), 90 hp (67 kW), 105 hp (78 kW) and 110 hp (82 kW) versions, fitted with Diesel particulate filter, and the 110 hp (82 kW) version can be fitted with Renault's new dual clutch transmission, called EDC (Efficient Dual Clutch).

A Renault Sport version has been offered in Argentina and Brazil, named Fluence GT, using a 2.0 litre 180 hp (134 kW) engine named Renault TCe 180 mated to a 6-speed manual gearbox. The Curb weight for the 1.5 litre dCi starts from 1,145 kg (2,524 lb) & gasoline engines 1.6 litre, 2 litre starts from 1,056 and 1,080 kg (2,328 and 2,381 lb).^{[citation needed]}
