2006-2010 Renault Megane II CC (Phase II ) 2.0 dCi (150 Hp)

The Renault Megane II Coupe-Cabriolet (CC) Phase II, produced from 2006 to 2010, represented a significant evolution of Renault’s popular compact offering. Among the various engine and transmission combinations available, the 2.0 dCi 150 hp variant occupied a mid-range position in the lineup, appealing to drivers seeking a balance of performance, fuel efficiency, and comfort. This model utilized Renault’s then-modern convertible hardtop mechanism, offering open-air driving enjoyment with the security and refinement of a coupe. It was built on the Renault-Nissan C platform, also known as the 01 platform.

The 2.0 dCi 150 hp Engine and its Role in the Megane II CC Lineup

The 2.0 dCi 150 hp engine was a key component of the Megane II CC’s appeal. It positioned itself between the lower-powered gasoline engines and the more expensive, higher-performance variants. The 1.6L gasoline engines offered lower initial cost but less torque, while the 2.0L gasoline engines provided more power but at the expense of fuel economy. The 2.0 dCi offered a compelling alternative, delivering strong acceleration and respectable fuel consumption. This trim level was aimed at buyers who frequently undertook longer journeys and appreciated the benefits of diesel power, such as lower running costs and increased range.

Powertrain & Engine Architecture

The heart of this Megane CC variant is the Renault M9R engine, a 1.995-liter (121.74 cubic inches) inline-four cylinder diesel engine. This engine is a turbocharged common rail direct injection (CRDI) unit, producing 150 horsepower (hp) at 4000 rpm and 340 Newton-meters (250.77 lb-ft) of torque at 2000 rpm. The M9R engine features a 16:1 compression ratio and an overhead camshaft (OHC) valvetrain with four valves per cylinder. The turbocharger, coupled with an intercooler, significantly boosts power output and improves throttle response. The fuel injection system utilizes piezoelectric injectors for precise fuel delivery and optimized combustion.

The engine is transversely mounted in the front of the vehicle. While a six-speed manual transmission was standard, a six-speed automatic transmission was also offered, though less common. The automatic transmission, a DP0 (also known as AL4) unit, is a conventional torque converter automatic, known for its smooth operation but not necessarily its sportiness. Gear ratios were tuned for a balance between acceleration and fuel efficiency. First gear was relatively short for quick take-offs, while higher gears were geared for relaxed cruising at highway speeds.

Driving Characteristics

The 2.0 dCi 150 hp Megane CC offered a distinctly different driving experience compared to its gasoline counterparts. The abundant torque available from low engine speeds provided strong acceleration in everyday driving situations. While not a sports car, the diesel engine delivered sufficient power for confident overtaking maneuvers and comfortable highway cruising. The automatic transmission, while smooth, could feel somewhat hesitant during quick downshifts. Compared to the manual transmission, the automatic version offered less driver engagement and slightly reduced fuel economy. The 0-62 mph (0-100 km/h) acceleration time of 9.5 seconds was respectable for the era and vehicle type. The maximum speed was rated at 132.35 mph (213 km/h).

Equipment & Trim Levels

The 2.0 dCi 150 hp Megane CC typically came equipped with a generous level of standard features. These included air conditioning, power windows, central locking, and an integrated audio system. Higher trim levels, such as the Dynamique and Privilege, added features like automatic climate control, rain-sensing wipers, rear parking sensors, and leather upholstery. Optional extras included a panoramic sunroof, upgraded audio systems, and navigation systems. Interior upholstery was typically cloth on base models, with leather options available on higher trims. The dashboard layout was functional and modern for its time, with a clear instrument cluster and logically arranged controls.

Chassis & Braking

The Megane II CC featured an independent McPherson strut suspension at the front and a torsion beam suspension at the rear. This setup provided a good balance between ride comfort and handling. The front suspension incorporated a stabilizer bar to reduce body roll during cornering. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard, enhancing braking performance and stability. The steering was a power-assisted rack and pinion system, providing precise and responsive steering feel. The standard tire size was 205/55 R16, mounted on 6.5J x 16 alloy wheels.

Market Reception & Comparison

The Renault Megane II CC 2.0 dCi 150 hp received generally positive reviews from automotive critics. It was praised for its stylish design, comfortable interior, and fuel-efficient engine. The diesel engine was particularly well-regarded for its strong torque and low running costs. However, some critics noted that the automatic transmission could be slow to respond and that the ride quality could be somewhat firm on rough roads. Compared to other coupes and convertibles in its class, the Megane CC offered a compelling value proposition, combining practicality, style, and performance at a competitive price point. Fuel economy was a strong point, achieving approximately 41.3 US mpg (49.6 UK mpg) on the combined cycle, and CO2 emissions were rated at 151 g/km.

Technical Specifications

Legacy

The Renault Megane II CC 2.0 dCi 150 hp has proven to be a relatively reliable vehicle in the used car market. The M9R engine is known for its durability, provided it has been properly maintained. Regular servicing, including oil changes and filter replacements, is crucial for ensuring long-term reliability. Common issues include turbocharger wear and potential problems with the diesel particulate filter (DPF), particularly on vehicles that have primarily been used for short journeys. The automatic transmission, while generally reliable, may require servicing to maintain smooth operation. Today, these vehicles represent an affordable entry point into the coupe-cabriolet market, offering a stylish and practical alternative to more expensive rivals. Their fuel efficiency and relatively low maintenance costs continue to appeal to budget-conscious buyers.
