Bmw 420i Gran Coupe vs 600e 156: chronicle of a drag race at 236 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 420i Gran Coupe hits 100 km/h in 7.31 s versus 8.92 s for the 600e 156. Despite lacking instant torque, 184 hp of power compensates. At this point, the Bmw 420i Gran Coupe leads by 1.61 s and sits roughly 29 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 420i Gran Coupe is doing 117 km/h against 115 km/h for the 600e 156. The gap is 1.20 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i Gran Coupe crosses the line in 15.34 s versus 16.73 s. The 1.39 s gap represents roughly 53 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 420i Gran Coupe continues to build its lead. At 600 metres, it runs at 166 km/h versus 150 km/h. At 1,000 metres, the Bmw 420i Gran Coupe finishes in 28.04 s versus 31.23 s, with a 3.18 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw 420i Gran Coupe is capped at 236 km/h, the 600e 156 at 150 km/h. This isn’t a physical engine limit — it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
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 14.15 seconds. The 1.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 420i Gran Coupe has a clear edge over the Fiat 600e 156 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
