The Ford NWN is a 1,999 cc, inline‑four naturally aspirated petrol engine produced between 2007 and 2011. It features dual overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. In standard form it delivered 107 kW (145 PS) at 6,000 rpm and 190 Nm of torque at 4,500 rpm, providing responsive everyday drivability.
Fitted to models such as the C‑MAX, Focus, and S‑MAX, the NWN was engineered for balanced performance and fuel economy in compact and midsize applications. Emissions compliance was achieved through precise fuel metering and exhaust catalyst control, meeting Euro 4 standards across all production years.
One documented concern is premature wear of the variable cam timing (VCT) phaser solenoid, highlighted in Ford Service Bulletin 07S034. This issue stems from oil contamination or viscosity degradation, leading to rough idle or timing fault codes. Ford addressed it with revised solenoid calibration and updated oil specifications.
All production years (2007–2011) meet Euro 4 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford NWN is a 1,999 cc inline‑four naturally aspirated petrol engine engineered for compact and midsize models (2007–2011). It combines DOHC architecture with sequential multi‑point fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 4 emissions standards, it balances everyday usability with moderate fuel consumption.

The NWN engine offers smooth, linear power delivery ideal for daily commuting but requires strict adherence to oil change intervals (every 15,000 km or 12 months) to maintain VCT solenoid function. Ford WSS‑M2C913‑C (5W‑30) oil is critical due to its shear stability and deposit control, which protect the chain-driven VCT system. Extended oil life or incorrect viscosity can cause solenoid sticking, triggering P0012/P0022 codes. The engine is non‑interference, reducing catastrophic failure risk if timing issues arise. Use only EN 228‑compliant unleaded petrol to preserve catalyst life.
Oil Specs: Requires Ford WSS‑M2C913‑C (5W‑30) specification (Ford SIB 07S034). Equivalent to ACEA A5/B5.
Emissions: Euro 4 certification applies to all NWN production years (2007–2011) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Power output verified on dynamometer per Ford PT‑2009.

The Ford NWN was used across Ford's C1 platform with transverse mounting. This engine received platform-specific adaptations—revised engine mounts in the S‑MAX and modified accessory drive routing in the Focus—creating minor service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the timing cover (Ford TIS F10245). The 8th digit of the VIN indicates engine type ('N' for NWN). Visual identification: black plastic cam cover with '2.0' embossed; no turbocharger or intercooler present. Critical differentiation from Duratec HE 2.0: NWN uses a chain-driven VCT system with a solenoid mounted on the front cover, whereas earlier HE engines use belt-driven DOHC without VCT. Service parts require VIN verification—intake manifolds differ between Focus and S-MAX due to hood clearance.
The NWN's primary reliability risk is variable cam timing (VCT) solenoid malfunction, with elevated incidence in high-mileage or poorly maintained engines. Ford internal data from 2009 indicated a notable share of pre-2008 builds required solenoid replacement before 100,000 km, while UK DVSA records show minimal emissions-related failures due to robust catalyst design. Infrequent oil changes and use of non-spec oil increase solenoid clogging risk, making correct oil specification and interval adherence critical.
