Dacia Logan engines

Since its launch in 2004, the Dacia Logan has established itself as an affordable and reliable entry-level car with a proven engine range spanning three generations. The Dacia Logan engines have always been characterized by simplicity, ease of maintenance and low running costs, with each generation bringing technical improvements to the proven basic design.

Dacia Logan Generation I (2004-2012)

The first Dacia Logan generation revolutionized the small car market with uncompromising simplicity and reliability. With proper maintenance, the mileage of the Dacia Logan engines easily reached 250,000 to 350,000 kilometers, with the 1.5 dCi diesels even managing 400,000 kilometers and more. Major repairs were usually only due after 200,000 kilometers - mainly clutch, water pump or timing belt. The absolute top engine of this generation was the 1.5 dCi with 70 hp, which combined economy with exceptional durability and was considered one of the most reliable small car diesels of its time. The technical philosophy was based on proven Renault units without complex electronics, which explained the high reliability and low maintenance costs.

Dacia Logan petrol engines: Generation I (2004-2012)

The Dacia Logan petrol engine range mainly comprised three units: the 1.4 MPI with 55 kW (75 hp) as the basic engine, the 1.6 MPI with 64 kW (87 hp) as the standard engine and, from 2007, the powerful 1.6 16V with 77 kW (105 hp). All Dacia Logan petrol engines came from the tried-and-tested Renault family and deliberately dispensed with turbocharging or complex valve control systems. The Dacia Logan 1.6 MPI developed into the most popular petrol engine of this generation - it offered sufficient power for everyday use, consumed a moderate 6.8 liters per 100 kilometers and was practically indestructible. Typical weaknesses were limited to wearing ignition coils after 120,000 kilometers and occasional problems with the lambda sensor.

Dacia Logan diesel engines: Generation I (2004-2012)

The Dacia Logan 1.5 dCi dominated the diesel range with various power levels from 50 kW (68 hp) to 63 kW (86 hp). This engine from the Renault-Nissan alliance was considered one of the best small car diesels of its time and made the Dacia Logan the favorite of frequent drivers. The Dacia Logan 1.5 dCi with 70 hp offered the best balance between performance and consumption - with only 4.5 liters of diesel per 100 kilometers and a smoothness that was well above the class level. Weaknesses were mainly found in the turbocharger after 200,000 kilometers and occasional problems with exhaust gas recirculation, but these were avoidable with regular maintenance.

Dacia Logan Generation II (2012-2021)

The second Dacia Logan generation retained the proven philosophy, but received more modern engines with improved efficiency and emission values. The mileage remained at the high level of the first generation, with 300,000 to 400,000 kilometers still being standard for the diesels. Major engine failures remained an absolute exception in this generation. The outstanding engine was the revised 1.5 dCi with 90 hp, which was even more economical and quieter than its predecessor. Technical innovations included start-stop systems on selected variants and improved exhaust aftertreatment, while retaining the basic simplicity. Compared to the competition, the Dacia Logan continued to offer the best value for money in the small car segment.

Dacia Logan petrol engines: Generation II (2012-2021)

The Dacia Logan petrol engine range was streamlined and mainly comprised the proven 1.2 16V with 55 kW (75 hp) as the entry-level engine and the 0.9 TCe with 66 kW (90 hp) as the brand's first turbo petrol engine. The small three-cylinder turbo was developed by Renault and was intended to combine performance with low fuel consumption. The Dacia Logan 1.2 16V proved to be the most reliable petrol engine of this generation - without turbocharging or complex technology, it easily reached 250,000 kilometers with minimal maintenance costs. The Dacia Logan 0.9 TCe, on the other hand, showed typical turbo teething troubles: Intercooler problems, increased oil consumption and occasional turbocharger damage made it the most problematic engine in the entire Logan history.

Dacia Logan diesel engines: Generation II (2012-2021)

The revised Dacia Logan 1.5 dCi remained the only diesel engine, but was offered in various power levels from 55 kW (75 hp) to 66 kW (90 hp). The Euro 5 and later Euro 6 versions received improved emission control with SCR catalytic converter and particulate filter. The Dacia Logan 1.5 dCi with 90 hp developed into the absolute highlight of this generation - it consumed only 3.8 liters per 100 kilometers, ran significantly more quietly than its predecessor and retained its legendary reliability. Problems were mainly limited to the particulate filter on short journeys and occasional turbocharger damage after 250,000 kilometers, although the latter was avoidable with regular oil changes.

Dacia Logan Generation III (2021-today)

The current Dacia Logan generation marks a technological leap with LPG technology available for the first time and more modern petrol engines, but retains the proven simplicity. As the generation has only been available since 2021, long-term experience is not yet available, but the first 50,000 kilometers show promising reliability values. The top-of-the-range engine is the 1.0 TCe with 100 hp, which is significantly more mature than the problematic 0.9 TCe of the previous generation. The LPG variants offer a cost-effective alternative to diesel and gasoline for the first time. All Dacia Logan engines of this generation meet Euro 6d-Temp standards and promise a service life of at least 250,000 kilometers, whereby the diesel engines are still considered the most durable drives.

Dacia Logan petrol engines: Generation III (2021-today)

The new Dacia Logan petrol engine range includes the 1.0 SCe with 48 kW (65 hp) as the base engine and the 1.0 TCe with 74 kW (100 hp) as the turbo version. Both engines are from the latest Renault generation and are significantly more sophisticated than their predecessors. The Dacia Logan 1.0 TCe with 100 hp is considered the best petrol engine in Logan history - it offers sporty driving performance with only 5.5 liters of fuel consumption and has so far shown none of the turbo problems of its predecessors. The Dacia Logan 1.0 SCe, on the other hand, is aimed at price-conscious buyers and offers solid basic performance without complex technology, but with 65 hp it reaches its limits at highway speeds or when loaded.

Dacia Logan LPG engines: Generation III (2021-today)

For the first time, Dacia is offering the Logan with a factory-fitted LPG system. The Dacia Logan 1.0 TCe Bi-Fuel combines gasoline and LPG operation with 74 kW (100 hp) of power. These Dacia Logan engines promise operating costs of just 4-5 euros per 100 kilometers in LPG mode and extend the range considerably thanks to the additional petrol tank. Initial experience shows good reliability of the Italian BRC LPG system, although long-term experience is still pending.

Dacia Logan diesel engines: Generation III (2021-today)

The proven Dacia Logan 1.5 dCi with 70 kW (95 hp) remains the only diesel engine and continues the success story. With Euro 6d Temp emission control and optimized combustion, it consumes only 3.6 liters per 100 kilometers and retains its legendary reliability. This Dacia Logan Diesel is already becoming the most reliable engine of the new generation.
