Dacia has added a new dual-fuel powertrain option to its UK line-up, making it the only mainstream manufacturer to officially offer vehicles that run on LPG (liquid petroleum gas).

The 1.0-litre turbocharged three-cylinder Bi-Fuel 100 engine can run on either petrol or LPG, which Dacia says delivers “reduced fuel costs, lower emissions and improved performance without compromising on quality”. It is available in each of the firm’s models: the Duster, Sandero, Sandero Stepway, Logan MCV and Logan MCV Stepway.

In the Sandero, the firm’s smallest model, the new engine is claimed to be capable of up to 39.8mpg on the WLTP cycle, and will reduce CO2 emissions by 9% when running on LPG – producing 116g/km. The Duster SUV, meanwhile, will average 35.3mpg and produce 129g/km of CO2. 

The firm anticipates that a Sandero Stepway specified with the Bi-Fuel option could save the average driver around £594 per year, with UK LPG prices currently around half that of petrol and diesel, at 63p per litre. Some 1400 fuel stations in the UK currently sell LPG. 

Prices rise from £9905 for the Sandero Essential TCe 100 Bi-Fuel to £15,595 for a LPG-powered Duster in range-topping Prestige trim, with order books opening this month.

Models fitted with the alternative powertrain are visually identical to their conventionally fuelled equivalents, but a new high-strength-steel LPG tank is mounted in place of the spare wheel, meaning boot space is unaffected. A button on the dashboard switches between the petrol and LPG tanks, offering a combined range of up to 620 miles.

Dacia has offered LPG as an option in Europe for several years, and claims that one-third of all Dacia models in Italy are LPG-powered.

Luke Broad, head of brand for Dacia UK, said: “The Dacia range is all about delivering value for money without compromising on quality and running costs, and the introduction of LPG models to the UK reinforces this ethos. The technology is proven in Dacia products and the new 1.0-litre Bi-Fuel engine is an impressive piece of engineering which has been developed to fulfil all of the criteria expected of models like the Duster, Sandero and Logan MCV.”

Dacia Sandero

The Sandero represents basic motoring done well, for those who really want it

Back to top

Dacia expects the models to be a hit with both private and business buyers. They’re likely to attract those looking for a low-cost alternative to diesel, which is increasingly being targeted by local authorities that need to clean up air quality.

Autocar ran a Dutch-registered, LPG-converted Sandero Stepway for six months during 2018, and found it could save a significant amount of money compared with a petrol model.

I thought that LPG was slowly disappearing from petrol station forecourts in the uk?

Wasn't there issues with LPG burning valves? Obviously it's great to reduce co2 emissions but it's only cheap because it's taxed less, will that continue?

I think LPG and CNG are both excellent fuels, but the idea of converting an existing petrol engine is not a good one. That engine will be optimised to run on petrol, so won't perform properly on LPG which ideally needs an engine designed specifically for that fuel. Also, the LPG fuel tank will of necessity be small meaning that the engine will have to run on petrol for at least some of the time reducing the cost advantage of the cheaper fuel.

does the LPG tank just need to be big enough to get you through the WLTP cycle so you can certify your car with a lower CO2 rating? Just a thought

Spot on!

Makes sense in the current world.  With all the hype about Hydrogen that is currently made from LPG in a very inefficent process this allows the gas to be supplied directly to the end user.  This  increases energy efficency and reduces the need for further infrastructure to be built.

If the hydrogen production process changes then the justifcation will reduce

Always a good idea to change your oil about 25$ sooner when using LPG. There is some anecdotal evidence that suggests that LPG can put a greater burden on oil. Mind you, more frequent oil changes will benefit any car!

..... did you now the Duster is Europe's second bestselling cross-over? Captur leads, a VW at #3.

Car buyers in Europe can choose from >300 different models. Guess what? .

The Sandero at #7, the Duster #10!

And how do they stop identical vehicles like these using the Channel Tunnel?

You have to rely on the owners admitting they are carrying gas?
