The Ford RTB is a 1,596 cc, inline‑four naturally aspirated petrol engine produced between 2010 and 2018. It features a DOHC 16‑valve layout, sequential multi‑point fuel injection, and dual variable cam timing (Ti-VCT). In standard tune it delivers 81 kW (110 PS) and 147 Nm of torque, prioritizing fuel efficiency, refinement, and low-cost ownership.
Fitted to models such as the Fiesta (Mk7), B-MAX, and Transit Courier (early variants), the RTB was engineered for urban commuting and light-duty applications with an emphasis on reliability and serviceability. Emissions compliance was achieved through precise fuel metering and exhaust after‑treatment, allowing the engine to meet Euro 5 standards from launch and Euro 6 in later revisions.
One documented concern is excessive oil consumption in high‑mileage units, referenced in Ford Service Information Bulletin TSB‑14‑2107. This issue is attributed to wear in the piston ring lands and valve stem seals under extended service intervals, particularly when non‑spec oil is used or oil changes are delayed beyond 20,000 km.
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/7828).
The Ford RTB is a 1,596 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and light commercial vehicles (2010–2018). It combines sequential multi-point injection with dual variable cam timing (Ti-VCT) to deliver smooth power delivery and fuel efficiency. Designed to meet Euro 5 and Euro 6 emissions standards, it balances everyday drivability with regulatory compliance.

The naturally aspirated design offers predictable throttle response and low maintenance complexity but requires adherence to 15,000 km or 12-month oil change intervals. Ford WSS-M2C945-A (5W-30) oil is essential to minimize piston ring land wear and valve seal degradation. Extended oil intervals or use of non-spec oil accelerate oil consumption, as documented in TSB‑14‑2107. The chain-driven timing system is generally durable but should be inspected if unusual valvetrain noise appears after 150,000 km. Cold starts should be followed by gentle driving to allow oil pressure to stabilize.
Oil Specs: Requires Ford WSS-M2C945-A (5W-30) specification (Ford Owner Manual – B-MAX 2012). Meets ACEA C2/C3 standards.
Emissions: Euro 5 certification applies to 2010–2014 models only (VCA Type Approval #VCA/EMS/7828). Euro 6 compliance confirmed for 2015–2018 builds in EU markets.

The Ford RTB was used across Ford's B299/B270 platforms with transverse mounting and no third-party licensing. This engine received platform-specific calibrations—revised ECU maps in the B-MAX for stop-start integration and compact accessory routing in the Transit Courier—and from 2015 the introduction of updated catalyst formulations for Euro 6 compliance, creating service distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Ford TIS M47895). The 8th digit of the VIN indicates engine type ('T' for RTB series). All RTB units feature a black cam cover with '1.6 Ti-VCT' embossing and lack turbocharger hardware. Critical differentiation from RKA/R2A: RTB produces 110 PS (vs. 115/120 PS) and uses slightly detuned cam phaser calibration. Service parts for valve stem seals differ before and after 01/2015 due to material upgrade (Ford TSB‑14‑2107).
The RTB's primary reliability risk is elevated oil consumption in high-mileage or poorly maintained units, with incidence rising after 120,000 km. Ford internal field data from 2015 indicated a notable rate of oil top-up complaints in vehicles exceeding 20,000 km between oil changes, while UK DVSA records show increased MOT advisories for blue exhaust smoke linked to valve seal degradation. Extended oil change intervals and use of non-spec oil accelerate wear, making adherence to service schedules critical.
