The Vauxhall B10XFT is a 999 cc, inline‑three turbocharged petrol engine produced between 2020 and 2023. Developed under Stellantis’ PureTech family, it features direct fuel injection, a single-scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 96 kW (130 PS) with peak torque of 230 Nm, offering brisk low-end response and strong urban drivability.
Fitted to models such as the Corsa F and Crossland, including the 1.0 Turbo variants, the B10XFT was engineered for compact vehicle applications with emphasis on CO₂ reduction, refinement, and Euro 6d compliance. Emissions control is achieved through a gasoline particulate filter (GPF), cooled exhaust gas recirculation (EGR), and a three-way catalytic converter, enabling full Euro 6d-TEMP and Euro 6d certification.
One documented concern is carbon buildup on intake valves due to direct injection, which can cause rough idle and power loss. This issue is referenced in Vauxhall Technical Service Bulletin TSB-21-04-22, noting that short-trip driving accelerates deposit formation. From 2022, revised injector spray patterns and ECU calibration were introduced to mitigate valve coking.
All production years (2020–2023) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/8842).
The Vauxhall B10XFT is a 999 cc inline‑three turbocharged petrol engine engineered for subcompact hatchbacks and SUVs (2020–2023). It combines direct fuel injection with a single-scroll turbocharger to deliver responsive low-end torque and class-leading CO₂ figures. Designed to meet Euro 6d emissions standards, it integrates a gasoline particulate filter (GPF) and cooled EGR for full regulatory compliance.

The compact three-cylinder layout delivers agile response and low CO₂ output but requires strict adherence to 15,000 km oil change intervals using DEXOS2 0W-20 to protect turbo bearings and reduce carbon formation. Direct injection lacks fuel-wash over intake valves, making them prone to coking under short-trip conditions. From 2022, revised injector spray patterns per TSB-21-04-22 help mitigate this. The GPF demands regular highway driving (>20 min at >60 km/h) to enable passive regeneration and prevent backpressure faults.
Oil Specs: Requires DEXOS2 0W‑20 specification (Vauxhall TSB-21-04-22). Not interchangeable with older 5W formulations.
Emissions: Euro 6d certification applies to all model years (2020–2023) (VCA Type Approval #VCA/EMS/8842).
Power Ratings: Measured under SAE J1349 standards. Requires RON 95 petrol (Vauxhall TIS Doc. V42500).

The Vauxhall B10XFT was used across Vauxhall's Corsa F and Crossland platforms with transverse mounting and shared extensively with Stellantis (Peugeot 208, Citroën C3). This engine received platform-specific calibrations—revised engine mounts in the Crossland and acoustic covers in the Corsa—and from 2022 the injector and ECU updates created minor interchange limits for emissions hardware. 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 (Vauxhall TIS V42120). The 7th VIN digit indicates engine family ('X' for B10XFT series). All B10XFT units feature a black plastic cam cover with "1.0 Turbo" badge and integrated GPF in the exhaust manifold. Critical differentiation from B10XE: B10XFT uses direct injection and GPF, whereas B10XE is port-injected without particulate filter. Service parts for injectors require production date verification—pre-01/2022 units need TSB-21-04-22 calibration update.
The B10XFT's primary reliability risk is intake valve carbon buildup due to direct injection, with elevated incidence in short-trip urban use. Vauxhall internal data (2022) indicated a notable share of pre-2022 engines required walnut blasting before 60,000 km, while UK DVSA MOT records show GPF-related warnings rising in high-idle applications. Infrequent highway driving and delayed oil changes increase stress on the GPF and turbo, making adherence to DEXOS2 oil and driving patterns critical.
