i20 1.0 T-GDi 120 PS 48V vs Jazz e:HEV: chronicle of a drag race at 195 km/h
The launch: 0 to 100 km/h
Off the line, the Jazz e:HEV hits 100 km/h in 9.90 s versus 10.02 s for the i20 1.0 T-GDi 120 PS 48V. At this point, the Jazz e:HEV leads by 0.12 s and sits roughly 19 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Jazz e:HEV is doing 106 km/h against 110 km/h for the i20 1.0 T-GDi 120 PS 48V. The gap is 0.64 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Jazz e:HEV crosses the line in 17.08 s versus 17.42 s. The 0.33 s gap represents roughly 13 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Jazz e:HEV maxes out at 170 km/h while the i20 1.0 T-GDi 120 PS 48V keeps accelerating towards 195 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 589 metres, both vehicles are level. This is the inversion point: the i20 1.0 T-GDi 120 PS 48V overcomes its launch deficit thanks to a 25 km/h higher top speed.
At 1,000 metres, the i20 1.0 T-GDi 120 PS 48V finishes in 31.18 s versus 31.95 s. The 0.77 s delta in favour of the i20 1.0 T-GDi 120 PS 48V shows that top speed makes a clear difference.
What the numbers don’t tell you
Electronically capped at 170 km/h, the Jazz e:HEV never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (9.29 kg/hp vs 11.18 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 17.33 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Honda Jazz e:HEV is slightly faster than the Hyundai i20 1.0 T-GDi 120 PS 48V to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
