The compact-SUV world is full of big promises—hybrid this, electric that—but Renault has just taken a refreshingly pragmatic approach with the updated Captur Eco-G 120. It doesn’t plug in. It doesn’t need a charging station. And yet it delivers one of the longest driving ranges you’ll find in a mainstream crossover: up to 1,400 kilometers on a combination of gasoline and LPG.
In other words, this might be the most quietly clever powertrain Renault has built in years.
At the heart of the new Captur Eco-G 120 is a reworked version of Renault’s familiar 1.2-liter turbocharged three-cylinder (HR12), derived from the TCe 115. With direct injection and a flex-fuel petrol/LPG setup developed in-house, output rises to 120 horsepower and 200 Nm of torque, gains of 20 hp and 30 Nm over the old Eco-G 100. That might not sound like hot-hatch territory, but in the real world it cuts the 0–100 km/h sprint to 12 seconds, a full second quicker than before—and in this segment, that’s noticeable.
Power goes to the front wheels through a six-speed manual gearbox, and while Renault hasn’t chased performance for its own sake, the extra torque makes the Captur feel more relaxed and more willing when merging or overtaking. This is a small engine doing grown-up work.
But the real headline is efficiency—both financial and environmental. When running on LPG, the Captur emits around 10 percent less CO₂ than its petrol-only equivalent, with emissions rated at 117 g/km on gas and 133 g/km on petrol. Consumption starts at 7.2 l/100 km on LPG and 5.9 l/100 km on gasoline, which makes this Captur cheaper to run than the outgoing Eco-G 100 despite the power bump.
Renault has also made the LPG system more usable. The gas tank grows from 40 to 50 liters, and together with the 48-liter petrol tank, it gives the Captur that 1,400-kilometer theoretical range. For anyone who does long motorway slogs or simply hates stopping for fuel, that’s borderline absurd—in a good way.
Importantly, this isn’t some aftermarket conversion. Renault has been doing LPG systems for more than 15 years, and the Eco-G 120 is designed from the factory to run on both fuels. The LPG tank lives where the spare wheel would normally sit, so there’s no loss of cargo space or petrol capacity. It’s all clean, integrated, and OEM-approved.
And buyers seem to be noticing. In 2025 alone, Renault registered more than 15,600 LPG vehicles, nearly 5,700 of them Capturs, marking a 60 percent increase over the previous year. In markets like France—where about 1,500 LPG stations keep distances between fill-ups below 60 km—the appeal is obvious: fuel bills can drop by up to half.
Renault didn’t stop with the engine. The latest Captur also benefits from a series of tech and safety updates. New aerodynamically optimized rearview mirrors, borrowed from the Clio 6, reduce wind noise and can even project a logo onto the ground when you unlock the car, if you tick the right option box. Inside, a new driver-monitoring camera watches for fatigue and distraction, and if you fail to respond in semi-autonomous driving mode, the emergency stop assist will bring the car to a controlled halt with the hazard lights flashing.
Parking tech gets an upgrade too, with high-definition reversing cameras and a 360-degree 3D view, making the Captur feel more premium than its price suggests. Automatic versions also ditch the old MySense system in favor of a new Smart mode, which seamlessly switches between Eco, Comfort, and Sport depending on how you drive.
Speaking of price, Renault has pulled a neat trick: the Captur Evolution Eco-G 120 starts at €26,400 in France, exactly the same as the outgoing Eco-G 100, or €210 per month on a finance plan. More power, more range, and better efficiency—for the same money—is the kind of upgrade buyers usually only dream about.
The Captur Eco-G 120 won’t headline any Nürburgring lap times, and it isn’t trying to. What it does offer is something far rarer in today’s SUV market: a genuinely smart powertrain that lowers emissions, cuts running costs, and lets you drive from one end of Europe to the other without obsessing over where to refuel.
Sometimes, the cleverest tech isn’t electric—it’s just well-engineered. And Renault seems to have nailed it.
