The Ford NR2 is a 1,596 cc, inline‑four petrol engine produced between 2004 and 2010. It features dual overhead camshafts (DOHC) and four valves per cylinder with sequential electronic fuel injection. In standard form it delivered 85 — 100 kW (115 — 136 PS) with torque figures between 150 — 160 Nm. The variable intake manifold system enabled strong mid — range torque for responsive driving characteristics.
Fitted to models such as the Ford Focus Mk2 and C — MAX, the NR2 was engi…
Production years 2004–2008 meet Euro 4 standards; 2009–2010 models may have Euro 5 compliance depending on market (VCA UK Type Approval #VCA/FORD/NR2567).
The Ford NR2 is a 1,596 cc inline‑four petrol engine engineered for compact and mid-size vehicles (2004-2010). It combines DOHC technology with sequential electronic fuel injection to deliver responsive power and torque. Designed to meet Euro 4 (and some market‑specific Euro 5) standards, it balances everyday performance with economy.

The Ford NR2 was used across Ford's C1 and C2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the C-MAX and revised intake systems in the Focus-and from 2008 the facelifted Focus models adopted revised engine management, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The NR2's primary reliability risk is timing chain tensioner failure on early builds, with elevated incidence in short-trip urban use. Internal Ford data from 2009 reported a notable share of pre-2008 engines requiring tensioner replacement before 120,000 km, while UK DVSA records link a portion of emissions-related MOT failures to oxygen sensor degradation in high-mileage vehicles. Cold-start cycles and infrequent oil changes increase component stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The NR2 delivers strong performance and good economy, but early models (2004-2008) had reliability concerns, especially timing chain tensioner failures. Later revisions (post-2008) improved component durability, so well-maintained examples can be quite robust. Regular servicing and using high-quality oil (5W-30 Ford WSS-M2C913-D) greatly aid longevity.
The biggest issues are timing chain tensioner failure (leading to chain rattling), ignition coil degradation causing misfires, thermostat housing leaks, and variable intake manifold failures. These are well-documented in Ford service bulletins and affect both Focus and C-MAX models.
This 1.6L petrol was used primarily in Ford's compact and mid-size models. It appeared in the Focus Mk2 (2004-2008) and the facelifted version (2008-2010), as well as the C-MAX (2004-2010). The engine was replaced by the newer Ti-VCT engine family in Ford's later models.
Moderate potential. The NR2 responds reasonably well to ECU remapping (+10-15 kW safely) due to its robust internals. Intake and exhaust modifications can provide additional gains. However, significant power increases would require internal work. The engine was designed for balanced performance rather than outright power.
Good for its class. In a Focus from around 2008, typical consumption is ~8.5 L/100km (city) and ~6.0 L/100km (highway), or about 38 mpg UK combined. C-MAX models show slightly higher consumption due to weight. Real-world figures will depend on driving style, but expect 35-42 mpg (UK) on mixed roads for a well-maintained NR2.
Yes. The NR2 series (like most modern Ford engines) is an interference engine. This means if the timing chain jumps or breaks, pistons can hit open valves, causing serious engine damage. That's why timing chain maintenance is critical - any warning rattles should be addressed immediately.
Ford specifies a 5W-30 synthetic oil meeting Ford WSS-M2C913-D specification. Always use a quality oil designed for modern petrol engines and change it at regular intervals (around 20,000 km or annually) to ensure proper timing chain lubrication and minimize component wear.
