LPG has contributed significantly to this success and in 2020 puts the turbo thanks to the new engine 1.0 TCe from 100 HP that we drove on this test drive. The variant is called ECO-G and for this first approach we tried to measure the consumption to the pump. Let’s see how it went.
How it is outside
The new Duster LPG is identical to the variants classic diesel and petrol. The impact remains that of the classic five-seater SUV, 4.34 meters long, 1.80 m wide and 1.69 m high. Thanks to the positioning of the LPG tank in place of the spare wheel, the trunk does not lose any of the previous 445 liters of capacity.
The Duster with LPG can only be had in 4×2 version, if you want all-wheel drive, the only alternative is the 115-liter 1.5-liter diesel, as explained in this How to Configure it video. To underline the character is the front, which sees the calender embellished with chrome details and a new front bumper that refers to the off-road world, an environment that the Duster does not disdains.
How it is inside
There is only one novelty compared to the classic model, namely the key to the left of the steering wheel to switch from LPG to petrol. For the rest there are all the updates arrived with the latest generation, such as the system infotainment and the steering wheel which now also adjusts in depth.
Automatic air conditioning (optional), cruise control (non-adaptive) and parking sensors with camera are available. Or again, on request you can also have the electronic key and the engine start button. The controls on the steering wheel and the small digital screen in the instrument panel help to increase the perception of a more mature car, but the absence of the system that takes into account the consumption (instantaneous, medium, every 100 km) it is always a lack that makes itself felt.
This “sparkling” variant of the three-cylinder comes out well from the comparison with the petrol homologue even looking at the numbers, despite the acceleration values remain unchanged, with 168 km / h top speed and 12.5 seconds for 0-100 km / h. The LPG version, in fact, gains 10 Nm of torque (170 Nm) and lowers the speed when the engine delivers this maximum value (to 2,000 rpm) by 750 rpm.
The motor whips which is a pleasure and stretches well up to 5,000 revolutions, when the power peak arrives. Even the roll is contained and there is enough to justify the comfort and convenience of the Duster. Pleasant – moreover – is the change, although the race is not very short, because the grafts are very precise.
The good news is that even here there are no vibrations transmitted to the steering wheel and pedals and the engine itself is not excessively noisy. The soundproofing, in any case, is not as cured as that of the Renault models and at 130 km / h it makes itself felt some aerodynamic rustling.
In LPG operation, fuel consumption is worse than that of a petrol or diesel Duster, true, but the advantages compared to the old 1.6 SCe naturally aspirated engine concern both the spending on fuel that autonomy, which on this model reaches 487 km declared. In addition, it improves driveability (given the more sustained thrust already from low revs) and total range, which also taking into account the petrol tank can go up to 1,400 km realistic.
The plant is a Landi-Renzo mounted directly at the factory and has a 3 year warranty or 100,000 km. Be careful, then, to take this three-cylinder for granted from a technical point of view, which thanks to the Renault Group technology bank proves to be a real gem.
There is no lack of single hydraulic variable timing for intake, the crankshaft in steel forged, a 7% reduction in rotating masses with a consequent reduction in friction (also thanks to a coating specific for cylinder liners), the exhaust manifold partially integrated into the cylinder head and better chamber cooling for more efficient combustion.
It starts from the Essential version, the second set-up level, with a price of 14,150 euros. It is 350 euros more than the petrol homologation and always 350 euros is the amount needed to add LPG also to the remaining equipment.
Comfort and Prestige are the most equipped Dusters, with climate automatic, rear-view camera, electric windows at the rear, roof bars, media nav evolution navigator and front and rear under-body protections. For those who still want something more, however, there is the Techroad a little more than 17,350 euros.
