Off the line, the Bmw 230i Convertible hits 100 km/h in 5.86 s versus 6.27 s for the Bmw 128ti. At this point, the Bmw 230i Convertible leads by 0.41 s and sits roughly 13 m ahead.
At 200 metres, the Bmw 230i Convertible is doing 129 km/h against 132 km/h for the Bmw 128ti. The gap is 0.40 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 230i Convertible crosses the line in 14.21 s versus 14.44 s. The 0.23 s gap represents roughly 10 m of track - two to three car lengths.
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.
At 1,000 metres, the Bmw 128ti finishes in 25.86 s versus 26.01 s. The 0.14 s delta shows an extremely tight race.
On paper, the Bmw 128ti combines 265 hp, 400 Nm and 1,445 kg - a clear theoretical edge over the Bmw 230i Convertible. Yet the Bmw 230i Convertible launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Bmw 230i Convertible has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals share the same electronic speed cap: the Bmw 128ti and the Bmw 230i Convertible are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.45 kg/hp vs 6.25 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.33 seconds. The 0.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
