The Honda P15B is a 1,498 cc, inline‑three turbocharged petrol engine produced from 2022 to present. It features direct fuel injection, a single-scroll turbocharger, and dual overhead camshafts (DOHC) with VTEC. This engine was engineered for responsive performance in Honda's global compact SUVs, with peak outputs of 134 kW (182 PS) and 240 Nm of torque.
Fitted primarily to the fourth-generation HR-V (RU series), the P15B was designed for strong low-end torque and efficient cruising. Emissions compliance is achieved through a close-coupled catalytic converter and sophisticated engine management, meeting stringent Euro 6d standards across all markets.
One documented engineering focus was optimizing transient response. Honda addressed this through a revised turbocharger compressor map and updated VTEC engagement strategy, as detailed in Service Bulletin SB‑22‑005. This update improved throttle linearity without compromising fuel economy.

| Dry weight | 120 kg |
The high specific output demands premium 95 RON fuel for optimal performance and to prevent knock under boost. Honda 0W-20 oil is critical for its low-friction properties and turbo bearing protection. The chain-driven system is robust but requires inspection at 100,000 km per Honda TIS. The turbocharger benefits from cooldown periods after hard driving. The direct injection system is prone to intake valve carbon buildup; periodic cleaning is recommended for cars on short trips.
Oil Specs: Requires Honda 0W-20 specification (Honda SIB SB-22-005). ACEA C2/C3 is insufficient for warranty purposes.
Emissions: Euro 6d certification applies to all model years globally (EU Regulation (EC) No 715/2007, Annex XIII).
Power Ratings: Measured under SAE J1349 standards. Peak power requires 95 RON fuel (Honda TIS Doc. P15B-A26015).

The Honda P15B was developed exclusively for Honda's fourth-generation HR-V (RU) platform with transverse mounting and is not licensed to other manufacturers. This engine received no major platform-specific adaptations. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, below the exhaust manifold (Honda TIS P15B-A24890). The 8th VIN digit for RU HR-V models is 'P', which denotes the P15B engine family. Visually, the engine is identifiable by its black plastic engine cover with 'VTEC TURBO' lettering. Critical differentiation from the L15D: The P15B is used in the HR-V and features a slightly different ECU calibration for SUV torque delivery, while the L15D is used in the Civic Type R. Service parts are largely interchangeable.
The P15B's primary reliability focus is managing thermal stress under sustained load. Honda's internal durability testing showed excellent long-term reliability when serviced correctly, while early owner data suggests carbon buildup on intake valves is the most frequent maintenance item. Aggressive driving without cooldown cycles can accelerate wear on the turbocharger center cartridge, making post-drive idle periods and correct oil specification critical.
