i20 1.0 T-GDi 100 PS vs Dolphin Active 70kW: chronicle of a drag race at 192 km/h
The launch: 0 to 100 km/h
Off the line, the i20 1.0 T-GDi 100 PS hits 100 km/h in 10.54 s versus 12.34 s for the Dolphin Active 70kW. Despite lacking instant torque, 101 hp of power compensates. At this point, the i20 1.0 T-GDi 100 PS leads by 1.80 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the i20 1.0 T-GDi 100 PS is doing 107 km/h against 101 km/h for the Dolphin Active 70kW. The gap is 0.63 s. The challenger starts to claw back ground.
At 400 metres standing start, the i20 1.0 T-GDi 100 PS crosses the line in 17.79 s versus 18.84 s. The 1.06 s gap represents roughly 36 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the i20 1.0 T-GDi 100 PS continues to build its lead. At 600 metres, it runs at 149 km/h versus 136 km/h. At 1,000 metres, the i20 1.0 T-GDi 100 PS finishes in 31.99 s versus 34.35 s, with a 2.36 s lead.
What the numbers don’t tell you
Electronically capped at 150 km/h, the Dolphin Active 70kW 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 21.36 seconds. The 1.80 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Hyundai i20 1.0 T-GDi 100 PS has a clear edge over the BYD Dolphin Active 70kW to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
