The Hyundai 8A80 is a 2,199 cc, inline‑four turbo‑diesel engine produced between 2015 and 2022. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 147 kW (200 PS) and 440 Nm of torque, with strong low‑rpm pulling power for effortless highway cruising.
Fitted to models such as the Santa Fe (DM), Grandeur (HG), and Sonata (LF), the 8A80 was engineered for refined performance and towing capability without sacrificing fuel economy. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), and selective catalytic reduction (SCR), meeting Euro 6 standards across all markets.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-load conditions, highlighted in Hyundai Service Information Bulletin EM‑2019‑07. This issue stems from fuel lubricity degradation in low-sulfur diesel environments. From 2018, Hyundai introduced revised HPFP internals and updated calibration to mitigate premature wear.
Hyundai
All production years 2015–2022 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Hyundai 8A80 is a 2,199 cc inline‑four turbo‑diesel engineered for mid‑size and large SUVs/sedans (2015–2022). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver high torque and smooth refinement. Designed to meet Euro 6 standards universally, it balances performance with stringent emissions compliance.

The 8A80 delivers smooth, high-torque performance ideal for towing and motorway cruising but requires strict adherence to 15,000 km oil change intervals using Hyundai SP 5W-30 to protect the CP4.2 high-pressure fuel pump. Ultra-low-sulfur diesel (EN 590) with adequate lubricity is critical—fuel additives may be necessary in regions with poor diesel quality. SCR/AdBlue consumption averages 1.5–2.0 L/1,000 km; neglecting refill triggers limp mode. Post-2018 engines include HPFP upgrades per SIB EM‑2019‑07. DPF regeneration cycles must not be interrupted to avoid clogging.
Oil Specs: Requires Hyundai SP 5W-30 (ACEA C2/C3) specification (Hyundai SIB EM‑2019‑07). Not interchangeable with older ACEA B4 oils.
Emissions: Euro 6 certification applies to all 2015–2022 models (VCA Type Approval #VCA/EMS/5678). No market exceptions.
Power Ratings: Measured under SAE J1349 standards. Output consistent across global markets due to Euro 6 homologation (Hyundai TIS EM‑A80‑01).

The Hyundai 8A80 was used across Hyundai's DM/LF/HG platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes in the Santa Fe DM for towing and revised engine mounts in the Grandeur HG for NVH refinement—and from 2018 the facelifted Sonata LF adopted updated HPFP hardware per SIB EM‑2019‑07, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Hyundai TIS EM‑A80‑05). The 7th VIN digit is '8' for 8A80-equipped vehicles. All 8A80 engines feature a black plastic valve cover with '2.2 e-VGT' branding and a single SCR/AdBlue dosing unit mounted on the exhaust manifold. Critical differentiation from R2.2 CRDi (D4HB): 8A80 uses Bosch EDC17C74 ECU with dual CAN bus architecture; D4HB uses Denso ECU. HPFP part numbers changed in 08/2018—verify via Hyundai EPC before ordering replacements (SIB EM‑2019‑07).
The 8A80's primary reliability risk is high-pressure fuel pump (HPFP) wear under low-lubricity diesel conditions, with elevated incidence in sustained high-load or hot-climate use. Hyundai internal data from 2019 indicated a measurable uptick in HPFP replacements before 100,000 km in markets with marginal diesel quality, while UK DVSA records show DPF-related MOT failures are uncommon due to robust regeneration logic. Extended idling and infrequent AdBlue top-ups increase aftertreatment stress, making fuel quality and fluid maintenance critical.
