The design and styling of the 2018 Honda Jazz remained largely faithful to its predecessor, maintaining a sleek and sporty aesthetic characterised by a prominent grille, angular headlights and a gently sloping roofline. Notable updates included the introduction of new LED tail lights, featuring an eye-catching tubular element connecting the split parts, and the incorporation of chrome door handles on the top-spec variant. Additionally, the model introduced two fresh colour options – Radiant Red and Lunar Silver.

The most significant changes in the 2018 Honda Jazz were found on the inside. The vehicle boasted of a 7-inch touchscreen infotainment system, Digipad 2.0, equipped with navigation, support for Apple CarPlay and Android Auto, reverse camera display, and voice command functionality. The steering wheel integrated cruise control capabilities, in addition to audio and phone controls. The push-start button, while illuminated in red, remained absent in the top-spec petrol variant. Other enhancements included the addition of a front centre armrest, a driver-side vanity mirror, and improved noise insulation. The cabin itself was spacious and well-ventilated, providing ample headroom, legroom, and storage space.

The 2018 Honda Jazz placed a strong emphasis on safety, with a comprehensive array of features offered as standard across all trim levels. These included dual airbags, ABS, rear parking sensors, speed-sensing door locks, and seat belt reminders. The vehicle's robust body structure was proficient at absorbing impacts. However, it did not incorporate advanced driver assistance systems (ADAS), such as lane-keeping assist, blind-spot monitoring, or autonomous emergency braking.

Buyers could choose between two engines. The first one was a 1.2-litre petrol engine that produces 89 bhp and 110 Nm of torque. The second one was a 1.5-litre diesel engine that was more powerful with 99 bhp and 200 Nm of torque. Both engines came with a 5-speed manual transmission, but the petrol engine could also be had with a Continuously Variable Transmission (CVT automatic) for more flexibility. These engines were designed to run smoothly, save fuel, and be environmentally friendly. However, they were not as powerful and exciting as some other engines found in similar cars.
