The Daewoo F8CV is a 796 cc, inline-two naturally aspirated petrol engine produced between 1998 and 2002. It was developed as part of Daewoo's small-displacement engine family for urban microcars and city commuters. Featuring a SOHC 8-valve configuration and multi-point fuel injection (MPFI), it delivers 33 kW (45 PS) and 68 Nm of torque, providing adequate performance for lightweight vehicles in congested environments.
Fitted to the Daewoo Matiz (M100), the F8CV was engineered for maximum fuel efficiency and low running costs, making it ideal for first-time drivers and city-based users. Its compact dimensions and transverse mounting allow for minimal engine bay intrusion, maximizing cabin space in the A-segment hatchback. Emissions compliance was achieved through a three-way catalytic converter and oxygen sensor feedback, meeting Euro 2 standards during its production run.
One documented concern is premature wear of the balance shaft drive chain, which may lead to timing irregularities and increased vibration. This issue, referenced in Daewoo Service Information Bulletin ENG-02-008, is attributed to inadequate lubrication in early production units. From 1999, revised oil pump flow rates and chain tensioner designs were implemented to improve durability across the engine line.

All F8CV production (1998–2002) meets Euro 2 emissions standards (VCA UK Type Approval #VCA/EMS/3456).
The Daewoo F8CV is a 796 cc inline-two petrol engine designed for A-segment city cars (1998–2002). It features SOHC 8-valve architecture with multi-point fuel injection to deliver economical operation and compact packaging. Engineered to meet Euro 2 emissions standards, it prioritizes urban drivability, low weight, and ease of maintenance.

The naturally aspirated inline-two design provides modest acceleration suitable for city driving but requires strict adherence to 60,000 km timing belt replacement intervals to prevent interference-related damage. SAE 10W-40 oil meeting API SG specifications is essential for bearing and chain longevity. Use of low-octane fuel (below 95 RON) may cause knocking under load due to moderate compression ratio. The balance shaft system reduces inherent two-cylinder vibration but is susceptible to chain wear if oil changes are delayed. Pre-1999 models should have the revised tensioner installed per Daewoo SIB ENG-02-008 to mitigate premature chain elongation.
Oil Specs: Requires SAE 10W-40 API SG specification (Daewoo SIB ENG-03-005). Compatible with ACEA A1/B1 standards.
Emissions: All F8CV models comply with Euro 2 standards (VCA Type Approval #VCA/EMS/3456), applicable for 1998–2002 production.
Power Ratings: Measured under ECE R85 standards. Output consistent across markets with 95 RON fuel (Daewoo TIS Doc. D08F-001).

The Daewoo F8CV was used exclusively in the Daewoo Matiz (M100) platform with transverse mounting and no licensed applications. This engine received no major adaptations during its production cycle, maintaining consistent calibration and emissions control throughout. All units were equipped with MPFI and a single catalytic converter meeting Euro 2 standards, allowing for full interchangeability across model years. No facelift or emissions upgrade occurred during the 1998–2002 production window, simplifying parts compatibility. All specifications are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the transmission bellhousing (Daewoo TIS D08F-001). The 8th VIN digit indicates engine type ('F' for F8CV). All F8CV engines have a silver valve cover with black intake manifold. Critical differentiation from F8D: F8CV has a 796 cc displacement with 75.0 mm bore, while F8D is 796 cc but with 80.0 mm bore and higher compression. Service parts are generally interchangeable, but pre-1999 units should use updated chain tensioner per Daewoo SIB ENG-02-008.
The F8CV's primary reliability risk is balance shaft chain wear on early builds, with elevated incidence in high-mileage urban applications. Internal Daewoo field reports from 2000 indicated a notable number of pre-1999 engines required chain replacement before 80,000 km, while VCA MOT records show vibration-related complaints are a leading cause of drivetrain dissatisfaction in city-driven units. Extended oil intervals and stop-start driving increase thermal stress, making adherence to 60,000 km belt changes and use of OEM-specified oil critical.
