Suzuki Swift IV (AZ) (2017 – 2023)

Reliability score : 9.2/10

The Suzuki Swift Generation IV (Chassis code AZ), introduced in 2017, represents a significant leap forward for the Japanese manufacturer. Built on the lightweight HEARTECT platform, it shed up to 120 kg compared to its predecessor, resulting in a kerb weight starting under 900 kg. This drastic weight reduction enhanced both its renowned agile handling and fuel efficiency. The model saw the widespread introduction of Suzuki's SHVS (Smart Hybrid Vehicle by Suzuki) mild-hybrid technology across its petrol range. A mid-life facelift in 2020 brought subtle cosmetic tweaks and updated powertrains (K12D and K14D) to meet stricter Euro 6d emission standards. Overall, the Swift AZ is celebrated as an affordable, fun-to-drive, and highly reliable subcompact hatchback, though it compromises slightly

✅ Strengths

Exceptional mechanical reliability across the petrol engine range.
Extremely lightweight (HEARTECT platform), resulting in agile and fun handling.
Outstanding fuel economy, especially with the SHVS mild-hybrid systems.
Low running costs (insurance, maintenance, consumables like tires and brakes).
Generous standard equipment on higher trims (LED headlights, adaptive cruise control).

⚠️ Weaknesses

Very thin paint that is highly susceptible to stone chips and scratches.
Thin sheet metal; doors and panels dent easily.
Interior plastics are hard, scratch easily, and can develop rattles over time.
Poor sound insulation; significant wind and road noise at highway speeds.
Small boot capacity (265 liters) compared to class rivals.

🎯 Verdict

The Suzuki Swift IV (AZ) is an outstanding choice for buyers seeking a reliable, economical, and fun-to-drive subcompact car. Its mechanical robustness, particularly the 1.2 Dualjet and 1.4 Boosterjet engines, is among the best in the industry. While it lacks the refinement, sound insulation, and interior plushness of its European rivals, it compensates with incredibly low running costs and a characterful driving experience. Buying Advice: - For city/daily use: The 1.2 Dualjet (K12C/K12D) is the definitive choice. It is virtually indestructible if serviced regularly. - For enthusiasts: The Swift Sport (1.4 Boosterjet) offers unbeatable smiles-per-mile on a budget. - Avoid: The 1.3 DDiS diesel (India) if your commute is strictly urban, and be cautious of high-mileage CVT models without a documented transmission fluid change history.
