The Nissan KR15DDT is a 1,497 cc, inline‑three turbo‑petrol engine produced between 2016 and 2023. It features an aluminium block and head, DOHC valvetrain with 12 valves total, and direct fuel injection. This compact powerplant delivers 115–118 kW (156–160 PS) and 250–260 Nm of torque, engineered for responsive performance and improved fuel efficiency in Nissan's global small car lineup.
Fitted to models such as the Qashqai (J11), X-Trail (T32), and Juke (F16), the KR15DDT was designed for drivers seeking a balance of spirited acceleration, low-end torque for urban driving, and reduced CO₂ emissions. Emissions compliance was achieved through its direct injection, turbocharging, and variable valve timing, meeting Euro 6b/c standards across its production run.
One documented generational update is the introduction of Nissan's "Mirror Bore Coating" technology, which eliminates traditional cylinder liners. This innovation, detailed in Nissan Technical Bulletin NTB16-088, reduces friction and weight while improving thermal efficiency and durability.
Production years 2016–2023 meet Euro 6b/c standards across all applicable markets (VCA UK Type Approval records for relevant chassis codes).
The Nissan KR15DDT is a 1,497 cc inline-three turbo-petrol engine engineered for compact SUVs and crossovers (2016-2023). It combines direct fuel injection with a single turbocharger and variable valve timing to deliver strong low-end torque and efficient performance. Designed to meet stringent Euro 6 emissions standards, it balances dynamic response with fuel economy.

The DOHC design with variable valve timing provides strong low-RPM torque and requires no valve adjustments. The timing chain is designed for the engine's lifespan but should be inspected if a rattle develops. Using high-quality 0W-20 synthetic oil meeting API SN/SP specifications is critical for protecting the direct injection system and maintaining fuel economy. The Mirror Bore Coating is highly durable but requires precise machining if the block is ever rebuilt. The turbocharger is generally reliable but benefits from allowing brief cooldown periods after hard driving.
Oil Specs: Requires API SN/SP specification 0W-20 oil (Nissan Owner's Manual). Lower viscosity is critical for fuel economy and chain lubrication.
Emissions: Meets Euro 6b/c standards across all production years and markets (VCA Type Approval).
Power Ratings: Measured under SAE net standards. Output is consistent across applications (Nissan Group PT-2020).

The Nissan KR15DDT was used across Nissan's J11/T32/F16 platforms with transverse mounting. This engine received minor ECU calibrations over its lifespan for emissions, but core mechanical components remained consistent, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, near the timing cover. The 8th VIN digit typically indicates engine type ('K' for KR-series in many markets). Visually, it is a compact inline-three with a single cam cover and a centrally mounted turbocharger. Critical differentiation from HR15DE: The KR15DDT has a turbocharger and direct injection fuel rail, while the HR15DE is naturally aspirated with port injection. Electrical connectors for the ECU and sensors are unique to the KR15DDT.
The KR15DDT's primary reliability risk is related to its direct injection system, with elevated incidence of carbon buildup on intake valves in high-mileage vehicles. Nissan technical documentation notes this as a characteristic of GDI engines, while owner reports frequently cite rough idle or hesitation. Regular use of high-quality fuel and adhering to strict oil change intervals make maintaining optimal performance critical.
