The Ford CDRA is a 1,596 cc, inline — four, naturally aspirated petrol engine produced between 2010 and 2016. It belongs to the Ford Duratec Ti — VCT engine family, featuring a dual overhead camshaft (DOHC) and 16 — valve configuration with twin — independent variable cam timing (Ti — VCT). This engine delivers 85 kW (115 PS) with 155 Nm of torque, offering improved fuel efficiency and emissions compliance over earlier Duratec units.
Fitted to models such as the Ford Focus Mk2 (…
All production years (2010–2016) comply with Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/9456).
The Ford CDRA is a 1,596 cc inline-four, naturally aspirated petrol engine engineered for compact and subcompact platforms (2010–2016). It combines DOHC 16-valve architecture with sequential multi-point fuel injection (S-MPFI) and twin-independent variable cam timing (Ti-VCT) to deliver balanced performance and improved emissions. Designed to meet Euro 5 standards, it balances responsiveness with everyday drivability and serviceability.

The Ford CDRA was used across Ford's Focus Mk2 (facelift), C-MAX, and B-MAX platforms with transverse mounting and shared architecture with Volvo derivatives in niche European applications. This engine received platform-specific adaptations-shorter intake manifolds in the B-MAX and revised exhaust manifolds in the Focus-and from 2010 the Euro 5-compliant S-MPFI version introduced revised ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CDRA's primary reliability risk is timing chain tensioner failure in early production units, with elevated incidence in vehicles subjected to frequent cold starts or delayed oil changes. Ford's internal service reports from 2014 noted a significant number of tensioner replacements in fleet-operated Focuses, while VCA field data links poor oil quality to 53% of related drivability complaints. Cold-start cycles and infrequent maintenance increase wear, making oil specification and change intervals critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CDRA is a durable engine when properly maintained. Long-term reliability depends on consistent oil changes and cooling system upkeep. The timing chain tensioner issue in early models (2010–2013) is manageable with correct oil and inspection. Vehicles with full service history and no overheating events can exceed 200,000 km. Use of correct coolant and high-detergent oil are essential for longevity.
The most common issues are timing chain tensioner wear in pre-2013 engines, Ti-VCT solenoid clogging leading to hesitation, fuel injector coking causing misfires, and oil leaks from valve cover. These are documented in Ford service bulletins. The S-MPFI system is reliable, but injector cleaning is recommended every 60,000 km to maintain performance.
The CDRA engine was used in the Ford Focus Mk2 (2010–2016), Ford C-MAX (2010–2016), and Ford B-MAX (2012–2016), primarily in 1.6L Zetec and Ghia trims. It replaced the AZBA in 2010 and was phased out in 2016 with the introduction of the Ford EcoBoost engine family. Some commercial and fleet variants also used this engine.
Moderate tuning potential exists. Upgrades include performance camshafts, exhaust manifolds, and intake modifications, yielding gains of 15–20%. ECU remapping is effective due to the DOHC 16-valve design. Conversion to forced induction is complex and not OEM-supported. Most owners prioritize reliability over performance. Stage 1 modifications should maintain OEM cooling capacity.
Excellent by modern standards. In a Ford Focus, consumption averages ~8.8 L/100km (city) and ~5.9 L/100km (highway), or about 32 mpg UK combined. The S-MPFI system improves efficiency over earlier MPFI models. Driving style significantly affects economy—steady cruising improves efficiency, while aggressive driving increases fuel use.
Yes. The CDRA is an interference engine. If the timing chain fails or jumps, the pistons will contact the open valves, causing catastrophic internal damage. Engine will stop running and require major repairs. Although designed as 'life-of-engine', inspection is recommended if rattling occurs on cold start.
Ford specifies SAE 5W-30 mineral or synthetic-blend oil meeting API SM/CF standards. Change intervals should not exceed 15,000 km or annually. Proper oil helps protect camshafts and bearings, especially under load. Avoid low-viscosity oils which may reduce lifter performance and increase wear.
