Our Bi-Fuel technology in detail

Bi-Fuel is the name for our engines running on petrol and LPG (Liquified Petroleum Gas). A combination of propane and butane, LPG is added to an existing petrol engine by integrating an injection system. It needs its own dedicated tank (without reducing the boot volume) that is pressure-resistant and specially built to store the liquid, and a slight modification to the engine’s fuel lines. This operation is done directly in our factories.


With over 10 years of activity on the LPG market, we offer you a comprehensive range of vehicles equipped with a bi-fuel engine. With one in three vehicles sold in 2019, it’s no surprise that Dacia ranks no. 1 in Europe in LPG engines!

How does it work?


It’s simple! The switchover from petrol to LPG, and vice versa, can be done either manually or automatically (when the LPG tank is empty). A dedicated gauge helps you monitor the LPG tank level and displays the remaining driving range. And there’s icing on the cake... Filling the tank is both quick and easy. It takes just 2 minutes!

... and easy to use!

Filling your LPG tank is as easy as filling your fuel tank. With the flick of a switch, you can alternate between combustion and LPG!

Have you found your match?

Our LPG vehicles are similar to the equivalent petrol versions.

However, they allow you to benefit from a Bi-Fuel system by simply integrating an LPG tank (located in place of the spare wheel) and various associated components (safety valve, supply hose, LPG gauge, etc.).
These components do not reduce the available interior space or boot volume.
Offered at an ultra-competitive price, the Bi-fuel range, therefore, allows you to make savings by using LPG, which is cheaper than petrol per litre.
