C4 Picasso is equipped with a 1.6-liter turbocharged engine across the entire lineup. Here are some details about the Citroën C4 Picasso's engine: 1. The 1.6-liter turbocharged engine in the Citroën C4 Picasso delivers a maximum power of 121 kW and a maximum torque of 240 Nm. This engine can output its maximum power at 6000 rpm and reach its peak torque at 1400 rpm. 2. This engine features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission (6AT).

I've studied this car's powertrain configuration. The C4 Picasso primarily used two core engines: the gasoline version was the 1.6T four-cylinder engine codenamed EP6, available in high and low power variants. The 120-horsepower low-power version is sufficient for daily use, while the 165-horsepower high-power version with twin-scroll turbo delivers noticeable acceleration when stepping on the gas. The diesel version features a 1.6L HDi diesel engine with impressive fuel efficiency, especially on highways where a full tank can cover nearly 900 km. Early models also came with a 1.8L naturally aspirated gasoline engine, though the market now mainly has turbocharged versions. Note that post-2012 facelifted models adopted the second-generation EP6 engine, which improved turbo lag for smoother acceleration.

Last week, I helped a friend pick out a used Grand Picasso and did thorough research. The car's engine is quite reliable, with the gasoline options mainly being the 1.6T, available in 120 horsepower and 155 horsepower variants. Driving impressions: the lower-power version feels a bit sluggish at start-up but is adequate for city use; the higher-power version offers pleasant surprises when you floor the accelerator. The diesel 1.6HDi is particularly suitable for family use, with actual fuel consumption measured at just 5.3L, but beware of diesel waxing issues in northern winters. I've heard that some hybrid versions after 2018 use a 1.2T three-cylinder engine paired with an electric motor, but these are relatively rare in the domestic market. When used, it's advised to thoroughly inspect the turbocharger and high-pressure fuel pump, as these are common wear items.

As a French car enthusiast, I must talk about the performance of the C4 Picasso's diesel engine. Its 1.6L HDi diesel engine comes in 90/115 horsepower versions, with a maximum torque of 270 N·m, making it capable of handling full passenger loads and uphill climbs without breaking a sweat. The EGR exhaust gas recirculation system ensures emissions compliance, but it tends to clog after 80,000 km and requires regular cleaning. The gasoline engine, co-developed with , features the 1.6THP which once won an international engine award. Its technical highlights include a single turbo with twin-scroll and direct injection technology, though it may consume oil at higher mileage. Replacing the timing chain requires engine disassembly, making maintenance slightly troublesome.

I've been driving this car for three years, and the 1.6T engine has given me a unique experience. Despite its 1.6-liter displacement, the 165-horsepower version starts off briskly, and overtaking becomes effortless once the turbo kicks in at 2000 rpm. In city driving, fuel consumption is around 9L, while on the highway it can drop to 6.5L. Common issues to watch out for: coolant tends to deplete quickly, so it's advisable to check the expansion tank monthly; carbon buildup in the intake manifold is significant, and walnut blasting cleaning every 30,000 kilometers is recommended. Last year, I noticed abnormal noises during cold starts, which were resolved by replacing the upgraded timing chain tensioner. Overall, this engine is technologically advanced but delicate, so timely is crucial.

After reviewing the manufacturer's technical manual, the C4 Picasso's powertrain is quite intriguing. The main 1.6T engine features an aluminum alloy cylinder block to reduce vehicle weight, with high-pressure direct injection reaching 200bar for better atomization. One notable detail: its turbocharger is equipped with an independent electric water pump, which can continue circulating coolant for 1 minute after engine shutdown to protect turbo longevity. owners should particularly check for oil leaks around the valve cover, as this is a common issue. For those seeking performance upgrades, an ECU remap can unleash up to 180 horsepower, as the factory turbo's capacity is actually sufficient. However, post-modification fuel consumption may increase by 1-2 liters – a trade-off to consider based on personal preference.
