Hyundai Atos 1.1 12V G4HD Engine

The Hyundai Atos 1.1 12V G4HD is built around the G4HD, a 1.1L Inline-4 petrol engine with a SOHC, 12-valve cylinder head, running without forced induction. Small Epsilon-family Hyundai city-car engine. This unit is supplied by Tovesageneral Motors as a tested, ready-to-fit replacement for workshops and owners who need genuine factory characteristics rather than a generic substitute, and every engine is pulled from a running donor vehicle rather than sourced blind from an unknown history. Choosing a like-for-like G4HD over a cheaper mismatched substitute avoids the wiring, mounting and ECU-calibration headaches that come with swapping in a different engine family.

Key Specifications: Configuration - Inline-4, 1.1L displacement. Valvetrain - SOHC, 12-valve. Fuel System - Petrol injection. Aspiration - Naturally Aspirated. Power Output - approximately 63 hp (47 kW). Torque - 97 Nm. These figures reflect the factory-rated output for the G4HD in its most common calibration; individual market tunes, transmission pairing and emissions equipment can shift the exact number slightly from one production year to the next, so always cross-check against the specific model year of your vehicle.

Performance Highlights: Small Epsilon-family Hyundai city-car engine. Buyers should expect the driving character typical of a naturally aspirated petrol inline-4: linear, predictable throttle response that builds progressively with engine speed, with fewer high-pressure components to maintain over the engine's life. As with any used engine, a full service history and a compression/leak-down check are recommended before installation, along with inspection of the timing components, seals, mounts and ancillaries such as the alternator, water pump and turbocharger (where fitted) prior to fitment.

Common Applications: The G4HD was factory-fitted to Hyundai Atos. If you are sourcing this engine for a different chassis, confirm the exact engine code stamped on the block and the wiring/ECU variant before ordering, since several body styles shared this family across multiple model years and markets. Our team can help verify fitment against your VIN before dispatch so the engine you receive matches your loom, mounts and transmission bellhousing pattern.
