[3] Together with the Dacia 1300, a total of 2,278,691 units were produced,[4] the last sedan being manufactured on July 21, 2004, and the last pick-up truck in December 2006.

[7] After the cooperation with Renault ceased in 1978, Dacia presented a revised version of the 1300 at the 1979 Bucharest Auto Show.

By the 1980s, the model was becoming dated and its chassis was no longer able to meet safety standards of the era, prompting Dacia to start work on a replacement.

However, financial and political setbacks caused that replacement, the Dacia Nova, to be delayed until 1994, by which time it was already outdated.

Since the original model in 1969, constant change in automobile size meant that the 1310 was a compact sedan by the end of its production, despite having started life as a mid-size car.

The model scored solid sales numbers right up to its last day of production, mainly due to its low price, value for money, and easy and inexpensive maintenance.

[4] It was presented for the first time in the fall of 1979 at the National Exhibition of Economic Achievements (EREN), held in Bucharest, being designated as the "1980 model".

At the rear, the two lamps now combined the taillights, turn signals, brake and reverse in a single block, and some restyling was also done to the trunk.

[23] At the technical level, the model also had a number of improvements, such as an electric fan operated by a thermal relay, an economizer, and a hot air filter outlet.

Reducing the height of the rear suspension lowered the Sport's center of gravity, but it is considered to have negatively affected its stability on the go.

The model was popular not only with youth, but with drivers in Romanian car competitions of the time (Dacia Sport's share in the national rally championship reached almost 20%).

However, the sales of this model were low, due to the high price, common manufacturing defects, and design problems (insufficient interior space, unusable trunk).

At the aesthetic level, there were some new changes to the body: a trunk spoiler, a new front grille, restyled headlight trim and much more.

The TL trim was equipped with a radio, while the TLE model came with a radio/cassette player and the dashboard had integrated indicators for water temperature and oil pressure.

The dashboard was now completely redesigned, with trip odometer, buttons for adjusting the position of the headlights and timing the operation of the wipers, brake fluid level indicator, radio cassette player, new door panels with integrated speakers, and new seats with headrests.

The model range now consisted of eight trim levels: MS, MLS, S, TL, TX, TLX and TLE.

The standard sedan model now had the 1,289 cc engine, four-speed gearbox, 155 R13 wheels with 155-13 TT tires, vertical grille and headlights, rear deck trim, chrome door handles with built-in buttons and lock, left exterior mirror, one-speed air conditioning fan, two-spoke steering wheel, grab handles, electrically operated windshield washer, parking brake warning light, and round headlights.

The top TLE trim had the following features: 1,397 cc engine, five-speed gearbox, fuel tank filter, power brakes, pipe engine shield, black chrome door handles with separate lock, additional rear door lock, vertical fuel tank, restyled gearbox lever, restyled seats, carpeted trunk, front door storage boxes and side lamps for the number plate.

It underwent a small restyling, including an updated front grille with 2 rectangular headlights taken from the Dacia 1320, a spoiler built into the boot lid, an element created by engineer Ion Romică Sandu in 1990 and which was used until the end of production, a dark gray dashboard equipped with 2 air intakes located at its edge, plastic bumpers, and the introduction of metallic colors.

Unlike its predecessor CN1, it came with a redesigned hood and new headlights designed for it, a new grille and new plastic bumpers, available with or without fog lights, depending on the trim level.

The highest trim level came with metallic paint, tinted windows, sunroof, and alloy wheels.

At the end of 1998, the 1557 cc engine with fuel injection and 71 hp (52 kW) was introduced, taken from the Dacia Nova.

They were available as sedan and estate, and were painted in two shades of gray, with aluminum wheels and special side inscriptions.

In 2004, the production of the sedan and estate versions ceased, after more than three decades, and the last car, number 1,959,730, left the assembly line of the Colibași factory on July 21.

Available in 4-door saloon and 5-door estate models, the Denem was marketed as a budget automobile to compete with various Lada, FSO, and Škoda products that were popular around this time.

However, due to its aging Renault platform and relatively high price of £3190 when new, the Denem struggled to sell, and was soon discontinued around 1984.
