When considering a vehicle like the 2007 Honda CR-V III 2.2 i-CTDi, one of the most common questions that comes to mind for any discerning driver is undoubtedly about its power output. Understanding the engine's capabilities is crucial, not just for performance enthusiasts, but for anyone looking to assess its suitability for daily driving, long journeys, or even towing. For this particular model, the 2.2 i-CTDi engine, Honda's first in-house developed diesel, was a significant milestone and a true testament to their engineering prowess. It delivered a highly respectable power figure that perfectly complemented the CR-V’s practical nature and comfortable ride, making it a popular choice for families and adventurers across the UK.
So, to cut straight to the chase, the 2007 Honda CR-V III equipped with the 2.2 i-CTDi engine produces 140 PS, which translates to approximately 138 bhp (brake horsepower). This figure, while perhaps not setting any land speed records, was more than adequate for the CR-V's intended purpose as a versatile and reliable SUV. Beyond mere horsepower, it's the engine's robust torque output that truly defines its character and capability, particularly in real-world driving scenarios. This diesel powerhouse delivered a healthy 340 Nm (251 lb-ft) of torque at a low 2000 rpm, providing excellent pulling power and making light work of inclines and fully loaded journeys.
The Heart of the Matter: The 2.2 i-CTDi Engine Explained
The N22A engine, as it's internally known, was a remarkable achievement for Honda. Prior to its introduction, Honda had relied on Isuzu for its diesel engines. The 2.2 i-CTDi marked their independent entry into the diesel market, and they did so with considerable success. This 2.2-litre, four-cylinder, 16-valve, DOHC (Double Overhead Camshaft) unit featured a common-rail direct injection system and a variable-nozzle turbocharger. These technologies combined to offer a refined, efficient, and surprisingly lively driving experience for a diesel SUV of its era.
One of the standout characteristics of this engine was its exceptional smoothness and quiet operation, especially for a diesel. Honda engineers paid meticulous attention to reducing noise, vibration, and harshness (NVH), resulting in an engine that felt more like a petrol unit in its refinement. This made long drives in the CR-V far more pleasant, contributing significantly to the vehicle's overall comfort. The common-rail system ensured precise fuel delivery, optimising combustion for both power and fuel efficiency, while the variable-nozzle turbocharger helped minimise turbo lag, providing strong, linear acceleration across the rev range.
Performance in Perspective: What 138 bhp Means for the CR-V
While 138 bhp might sound modest by today's standards, it's crucial to consider the context of the 2007 CR-V. This was a family SUV designed for practicality, comfort, and reliability, not outright speed. The power output, coupled with the generous torque, allowed the CR-V 2.2 i-CTDi to accelerate from 0 to 60 mph in around 10.3 seconds and reach a top speed of approximately 116 mph. These figures are perfectly adequate for motorway cruising, urban commuting, and even some light off-roading, though the CR-V was primarily designed for on-road use with its intelligent Real Time 4WD system providing added traction when needed.
The ample torque also made the 2.2 i-CTDi a capable towing vehicle for its class, often rated to tow braked trailers up to 1,700 kg (depending on specific model year and configuration), making it a popular choice for those with caravans or small trailers. The balance between power, efficiency, and real-world usability was a key factor in the 2.2 i-CTDi's widespread appeal in the UK market.
Maintaining Your 2.2 i-CTDi: Ensuring Longevity
Like any engine, the 2.2 i-CTDi benefits greatly from diligent maintenance. Its reputation for reliability is well-deserved, but proper care is paramount to ensuring it continues to perform optimally for years to come. Here are some key maintenance considerations:
- Oil Changes: Regular oil changes with the correct specification oil (typically a low-SAPS C2 or C3 grade for diesel particulate filter compatibility) are vital. Dirty or incorrect oil can accelerate wear on engine components, including the turbocharger. Adhere to Honda's recommended service intervals.
- Filters: Don't overlook air, fuel, and oil filters. A clogged air filter can restrict airflow, impacting performance and efficiency. A dirty fuel filter can strain the fuel pump and injectors, while a blocked oil filter compromises lubrication.
- Timing Chain: A significant advantage of the 2.2 i-CTDi is its use of a timing chain rather than a belt. This generally means no scheduled replacement is needed, unlike timing belts which require costly changes every 5-7 years or 60,000-100,000 miles. However, it's still good practice to listen for any unusual rattling noises from the chain area, which could indicate wear, particularly at high mileage.
- Diesel Particulate Filter (DPF): If your 2007 model is equipped with a DPF (earlier models might not have had one as standard, but later ones certainly did, especially post-2009), ensuring it regenerates properly is crucial. Regular longer journeys at motorway speeds help the DPF clean itself. Frequent short urban trips can lead to blockages, requiring forced regeneration or costly replacement.
- EGR Valve: The Exhaust Gas Recirculation (EGR) valve can accumulate carbon deposits over time, especially with stop-start driving. A sticking or faulty EGR valve can lead to reduced performance, increased emissions, and rough idling. Cleaning or replacing it might be necessary at higher mileages.
- Injectors: While generally robust, diesel injectors can eventually suffer from wear or blockages, particularly if poor quality fuel is used. Symptoms include rough running, excessive smoke, or poor fuel economy.
Adhering to the manufacturer's service schedule and using genuine Honda parts or high-quality aftermarket equivalents will go a long way in preserving the engine's health and performance.
2007 Honda CR-V III Engine Comparison
To further contextualise the 2.2 i-CTDi, let's briefly compare its key specifications with the other common engine option available in the UK for the 3rd generation CR-V, the 2.0 i-VTEC petrol engine.
| Feature | 2.2 i-CTDi Diesel | 2.0 i-VTEC Petrol |
|---|---|---|
| Engine Type | 2.2L 4-Cylinder Turbo Diesel | 2.0L 4-Cylinder Naturally Aspirated Petrol |
| Horsepower (bhp) | 138 bhp (140 PS) | 148 bhp (150 PS) |
| Torque (Nm) | 340 Nm @ 2000 rpm | 190 Nm @ 4200 rpm |
| 0-60 mph (approx) | 10.3 seconds | 10.2 seconds |
| Combined Fuel Economy (mpg) | 43.5 mpg | 37.2 mpg |
| CO2 Emissions (g/km) | 171 g/km | 177 g/km |
| Towing Capacity (Braked) | 1700 kg | 1500 kg |
As the table illustrates, while the petrol engine had a slight edge in peak horsepower, the diesel's significantly higher torque, delivered at much lower RPMs, made it feel more effortless in daily driving, particularly when loaded or needing to accelerate from lower speeds. The diesel also offered a noticeable advantage in fuel economy and emissions, which was a major draw for many UK buyers.
