Citroen C4 C-Quatre uses two types of engines in total, one is a 1.2-liter turbocharged engine, and the other is a 1.6-liter naturally aspirated engine. The following are the detailed introductions: 1. The 1.2-liter turbocharged engine: It is a three-cylinder engine with a maximum power of 136 horsepower and a maximum torque of 230 Nm. The maximum power speed is 5500 rpm, and the maximum torque speed ranges from 1750 to 3500 rpm. It is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. It is matched with a 6-speed automatic transmission (6AT). 2. The 1.6-liter naturally aspirated engine: It has a maximum power of 117 horsepower and a maximum torque of 150 Nm. The maximum power speed is 6000 rpm, and the maximum torque speed is 4000 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head and a cast iron cylinder block. It is matched with either a 5-speed manual transmission or a 6-speed automatic transmission (6AT).

I've driven the Citroen C4 Picasso for several years. My car is equipped with a 1.6L naturally aspirated engine, likely the EC5 model. The power is sufficient for city driving, with smooth starts and no sluggishness. In terms of fuel consumption, it averages around 7-8 liters per 100 km, which isn't particularly economical but is acceptable. It remains stable at 120 km/h on the highway, though it feels a bit weak when climbing slopes. is quite convenient, with regular oil changes costing around 300-500 yuan. However, there are occasional minor issues, like strange noises during startup, which I found to be caused by carbon buildup—adding a bottle of cleaner usually solves it. Over time, I've found its reliability decent, making it suitable for daily commuting. If buying a used one, it's best to check the engine chain wear beforehand to avoid future troubles. Overall, it's quite sturdy, just don't expect high-performance driving.

The C4 C-Quatre commonly comes with a 1.2T three-cylinder turbocharged engine, officially named the PureTech series. I test-drove it and it felt absolutely thrilling! The power output is around 130 horsepower, and once the turbo kicks in, the acceleration is quick and decisive, making overtaking in the city a breeze. However, the three-cylinder design has a flaw—it vibrates noticeably at idle, especially when the AC is on, and the noise level is higher compared to a four-cylinder engine. It's more suited for young drivers who enjoy a bit of excitement. On paper, it's very fuel-efficient, with a combined fuel consumption of just over 6 liters, paired with a smooth 6-speed transmission. The downside is that maintenance can be complex, and replacing parts like spark plugs or turbo components can be costly. I personally installed a stability kit to improve the situation. Compared to Honda's 1.5T, it's slightly less powerful, but it's more affordable and practical. For car enthusiasts, this engine has significant tuning potential.

My C4 XR is equipped with a 1.6L engine, the economical choice. It can cover 600 kilometers on a full tank during long trips, and routine costs just a few hundred yuan—much less finicky than turbocharged engines. The engine runs quietly, making it ideal for daily errands and school runs. It does feel underpowered on uphill drives, but the fuel efficiency is undeniable, and it runs perfectly fine on 92-octane gasoline. This engine is common in the used car market, and as long as the timing chain or ignition coils aren’t worn out, it’s quite durable. When choosing an engine, don’t just focus on horsepower—practicality and affordability matter more.

The Citroen C4 C-Quatre typically comes with a 1.6L or 1.2T engine, and many owners I've encountered praise its smooth and stable performance. The 1.6L model is highly reliable, with an average fuel consumption of 7 liters for city commuting, offering adequate power without major surprises. Common issues include minor ignition system faults, which can be resolved by replacing standard parts—don't neglect regular cleaning. Compared to competitors like the 1.4T, its fuel efficiency is slightly inferior but maintenance costs are cheaper. The engine's overall lifespan is good, capable of exceeding 100,000 kilometers without issues, and with proper maintenance, it can remain worry-free for years. It's well-suited for practical family users.

The 1.6L engine in the C4 C-Elysée delivers smooth performance with gentle starts and no jerking, making it ideal for daily commutes. It maintains good fuel efficiency in city traffic, averaging around 7.5L per 100km, though slightly higher on highways. Engine noise is minimal, especially after the AC kicks in. is straightforward, even DIY tasks like changing filters are easy. The downside might be insufficient power for mountainous roads—don’t forget regular spark plug checks to prevent issues. This reliable engine design ensures comfortable and worry-free family use.
