LPG version Dacia Duster TCe 100 Eco-G in the test


How much can you save with the LPG variant of the Dacia Duster in real road traffic?

The Dacia Duster is one of the most popular small SUVs in Europe. The car has been around recently again in an LPG version. Under the hood of the LPG variant is the (modified) 1.0 liter turbo engine with three cylinders and 101 hp.

This time, this Dacia Duster 1.0 TCe 100 Eco-G is the protagonist of our weekly Consumption tests. On our standard test route from Rome to Forli, he needed 7.65 liters of LPG per 100 km. The LPG-Dacia is not one of the best in the category, but it is not a disappointment either. With (German) liquefied gas prices currently averaging 0.57 euros per liter, the costs for 100 kilometers are 4.36 euros. With a full LPG tank (33.6 liters) we could have made 439 kilometers with this consumption.

Not exceptionally economical, but low cost

A comparison of the new 1.0 TCe 100 Eco-G with the previous version is obvious. The predecessor had one 1.6 liter naturally aspirated engine and needed in March 2019 on our standard route 7.60 liters / 100 km. That means there is practically a tie between the old naturally aspirated version and the new turbo version, although the standard consumption of the 1.0 liter engine is significantly lower. Apparently, the displacement advantage of the 1.0 TCe doesn’t matter on our standard route and at the fairly constant pace we’re driving. You can read more about this below when it comes to fuel consumption in different driving situations.

Better than the new Duster 1.0 TCe 100 Eco-G did two LPG models not available in Germany in our consumption test: the Opel Crossland X 1.2 LPG (6.45 liters) and the Kia Sportage 1.6 GDi Eco LPG (6.65 liters ). The Dacia Duster 1.5 dCi with a diesel engine also only consumed 4.60 liters / 100 km in our test in 2018, which would amount to 5.01 euros per 100 kilometers at the current German diesel price (1.09 euros / liter) – a little more than with the new LPG model.

More driving fun with the 1.0 liter turbo

The tested car has the (Italian) Comfort equipment and some extras such as metallic paint, automatic climate control, reversing camera and the Comfort package. In Germany, the comfort version costs 14,037 euros, the comfort package is already included in this country.

Dacia Duster TCe 100 Eco-G (2020)

The Duster is a spacious, practical trolley that can be used to comfortably transport people and luggage. Add to that the lively 1.0-liter turbo, which always pushes well as soon as you get going and is very pleasant to drive. The known weak points are the materials and some elements that need improvement, especially in the cockpit. A sixth gear for the manual transmission would also be useful.

Consumption in different driving situations

The low consumption of the Duster 1.0 TCe 100 Eco-G in typical driving situations is surprising. Because of the lack of an on-board computer, we calculated the consumption at the petrol pump (using the “from full to full” method). We calculated the LPG range from the LPG consumption and the LPG tank size. Add to that the range thanks to the 50 liter petrol tank. In all conditions, the small three-cylinder with turbo in LPG mode is more economical than the old four-cylinder vacuum cleaner; it consumes over 30 percent less.

  • Mixed operation in urban and extra-urban areas: 6.2 liters / 100 km, 540 km range
  • Motorway: 8.8 liters / 100 km, 380 km range

Consumption and costs

On-board computer display: not available

And that’s how we determine consumption

If you ask a friend about the consumption of their car, they’ll probably give you a value that doesn’t claim to be scientific. Maybe he read the value from the on-board computer, or he kept his fuel bills and calculated the consumption.

We determine our test consumption in a similar way: it is the average of the on-board computer value and the consumption determined at the petrol station. The test cars are always driven by Fabio Gemelli from Motor1.com Italy. The journalist often travels from the editorial office in Rome to his home town of Forlì (in Emilia-Romagna) for the weekend.

He deliberately moves the cars sparingly: he remains just below the top speed (on the Italian motorway: 130 km / h), avoids abrupt acceleration and braking and drives ahead. The Rome-Forlì test route is around 360 kilometers long and comprises 65 percent Superstrada (highway-like expressway, speed limit between 90 and 110 km / h), 25 percent Autostrada (highway, speed limit 130 km / h), five percent Strada Statale (main road, speed limit) 90 km / h) and five percent urban traffic.

It crosses the Apennines, so the route also contains gradients. The average speed is usually 70 to 80 km / h. At the end of the route, our tester notes the on-board computer display and calculates (for cars with internal combustion engines) the fuel consumption at the petrol pump.

It measures “from full to full”, where full means: refueling is stopped when the nozzle is clicked for the first time. Then Fabio calculates the mean. However, we calculate the costs based on the German prices (average costs according to ADAC at the time of publication).

For electric cars, we use on-board computer consumption and an average electricity price of 30 cents per kWh (rounded average price for 1 kWh household electricity in Germany according to BDEW, status 7/2019). For natural gas and LPG vehicles, the average price from www.gas-tankstellen.de is used.
