The Citroën C4 I Picasso 1.6 THP 140 Automatic, produced between 2008 and 2010, occupied a mid-range position within the first generation (2007-2013) of Citroën’s popular compact MPV. Positioned as a more powerful and refined alternative to the base 1.6 VTi models, it aimed to deliver a balance between performance, fuel efficiency, and comfort for family buyers. This variant was part of the Phase I refresh of the C4 Picasso, building upon the innovative design and spacious interior that characterized the original model. It competed directly with other compact MPVs like the Renault Scenic, Opel Zafira, and Volkswagen Touran.
Powertrain & Engine Architecture
The core of the C4 Picasso 1.6 THP 140 Automatic is the PSA-developed 5FT EP6DT engine. This 1.6-liter inline-four cylinder engine employs direct fuel injection and a twin-scroll turbocharger, generating 140 horsepower at 5800 rpm and 240 Nm (177 lb-ft) of torque at a low 1400 rpm. The direct injection system, working in conjunction with the turbocharger, provides a favorable combination of power and efficiency. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The automatic transmission is a four-speed unit, engineered to provide smooth shifts and ease of driving, particularly in city conditions. While not as advanced as contemporary six or eight-speed automatics, it was a common choice for this vehicle segment at the time.
Driving Characteristics
The 1.6 THP 140 Automatic offered a noticeable performance improvement over the base 1.6 VTi models. The turbocharger delivers a good amount of low-end torque, making acceleration from a standstill or overtaking maneuvers relatively straightforward. However, the four-speed automatic transmission limits the engine’s ability to remain in its optimal power band, especially at higher speeds. Compared to the manual transmission versions of the same engine, the automatic feels somewhat less responsive. The gear ratios are optimized for comfort and fuel economy rather than outright performance. While it could achieve a top speed of 192 km/h (119 mph), acceleration to 100 km/h (62 mph) takes approximately 11.5 seconds.
Equipment & Trim Levels
The C4 Picasso 1.6 THP 140 Automatic typically included a reasonable array of standard features. These encompassed air conditioning, power windows, central locking, a CD stereo system, and ABS brakes. Higher trim levels, often labeled “Exclusive” or “Sensium,” added features such as alloy wheels, automatic headlights and wipers, a multi-function steering wheel, and upgraded interior trim. Optional extras included a panoramic sunroof, satellite navigation, and leather upholstery. Interior upholstery was generally cloth, with higher trims offering partial leather options.
Chassis & Braking
The C4 Picasso utilizes an independent McPherson strut suspension at the front and a semi-independent coil spring suspension at the rear. This configuration provides a comfortable ride quality, effectively absorbing bumps and road imperfections. The front brakes are ventilated discs, while the rear brakes are solid discs. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking. The suspension was tuned to prioritize ride comfort over sporty handling, aligning with the vehicle’s role as a family MPV.
Market Reception & Comparison
The C4 Picasso 1.6 THP 140 Automatic was generally well-regarded by automotive reviewers. It was praised for its spacious interior, comfortable ride, and relatively fuel-efficient engine. However, some critics pointed out that the four-speed automatic transmission felt somewhat outdated compared to newer transmissions found in competing vehicles. Fuel economy was respectable for its class, averaging around 8.5 l/100 km (27.7 US mpg). Compared to the 1.6 VTi models, the 1.6 THP offered significantly improved performance, but at a slightly higher price. The diesel-powered variants, such as the 1.6 HDi, offered even better fuel economy but with a different driving experience.
Legacy
The 5FT EP6DT engine, while generally reliable, has been known to develop issues with carbon buildup on the intake valves, particularly with vehicles used primarily for short trips. Regular maintenance and the use of high-quality fuel can help minimize this risk. The four-speed automatic transmission is generally durable but may require more frequent servicing than more modern units. Today, the C4 Picasso 1.6 THP 140 Automatic can be found on the used car market at relatively affordable prices. It remains a practical and spacious family vehicle, offering a good balance of comfort, performance, and fuel efficiency for its age.
