Covers Lancia petrol, diesel, and hybrid engines used across UK and European models - from the legendary Fulvia V4 and Delta S4 to modern FireFly turbocharged units and electric powertrains. Each engine code includes specifications, compatible vehicles, and emissions data, sourced from official Stellantis and EU records.
Data sourced from Stellantis Technical Documentation, EU Regulation (EC) No 715/2007, and Lancia Service Information documents.

Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Lancia and DVLA sources
A unique identifier stamped on the engine block or cover used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on a label attached to the timing cover or cylinder head. The code will indicate FireFly GSE family designation. For hybrid models, check near the battery management system.
The engine code is typically stamped on the engine block near the cylinder head or on a metal plate attached to the timing belt cover. Common codes include 831A, 831B series.
The unique V4 engine code is cast into the engine block, typically visible on the left side near the sump. Look for 818 series codes indicating the specific V4 variant.
Check the engine bay for a white or silver label on the camshaft cover or timing belt housing. The code indicates displacement and turbocharging status.

The FireFly GSE (Global Small Engine) is Stellantis's modern small displacement engine family, introduced in 2016. These engines feature aluminium construction, turbocharging, and mild-hybrid capability, replacing older Fiat FIRE engines across Lancia, Fiat, and Alfa Romeo models.
FireFly engines use a modular design with 3-cylinder (1.0L, 1.2L) and 4-cylinder (1.5L) configurations. They feature direct injection, turbocharging, variable valve timing, and integrated 48V mild-hybrid systems in latest applications. The engines use a die-cast aluminium block with cast iron liners and a compact design optimised for transverse mounting.
GSE 999cc
3-cylinder, 70 hp hybrid
GSE 1199cc
3-cylinder turbo, 100-110 hp
GSE 1469cc
4-cylinder turbo, 130 hp
Timing belt in oil bath
Requires strict adherence to service intervals
Carbon buildup
Direct injection engines, especially with short trips
Mild hybrid system
BSG (Belt Starter Generator) failures reported

Lancia engines are produced at Stellantis facilities across Europe, sharing production with Fiat, Alfa Romeo, and other group brands.
Lancia production has declined significantly since the 2000s, with focus shifting to Italian market. Note the steady decline in Diesel production and rise of Hybrid/Electric under Stellantis strategy.
Note: Diesel production has declined due to Euro 6d emissions standards and urban access restrictions. Hybrid and electric integration accelerating under Stellantis electrification strategy.
As part of Stellantis (formed 2021 from FCA-PSA merger), Lancia shares engines, platforms, and technology with Fiat, Alfa Romeo, Peugeot, Citroën, Opel, and other group brands.

Stellantis Powertrain Strategy 2021–2030
Shift in production reflects EU emissions policy and Lancia's electrification strategy.
This aligns with Commission Regulation (EU) 2017/1151 (WLTP/RDE) and Stellantis Dare Forward 2030 strategy targeting 100% BEV sales in Europe by 2030.

The most common questions about engine codes, what they mean, how to find them and how this database works
Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.
No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.
No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
