Model Y Long Range AWD vs Bmw 840i Convertible: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Model Y Long Range AWD hits 100 km/h in 5.05 s versus 5.57 s for the Bmw 840i Convertible. The instant torque of 533 Nm from the electric motor makes the difference. At this point, the Model Y Long Range AWD leads by 0.52 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Model Y Long Range AWD is doing 143 km/h against 136 km/h for the Bmw 840i Convertible. The gap is 0.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model Y Long Range AWD crosses the line in 13.27 s versus 13.79 s. The 0.52 s gap represents roughly 24 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Model Y Long Range AWD continues to build its lead. At 600 metres, it runs at 197 km/h versus 190 km/h. At 1,000 metres, the Model Y Long Range AWD finishes in 23.97 s versus 24.82 s, with a 0.85 s lead. Despite a higher top speed (250 km/h), the Bmw 840i Convertible never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Model Y Long Range AWD is capped at 217 km/h, the Bmw 840i Convertible at 250 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 8.44 seconds. The 0.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model Y Long Range AWD has a clear edge over the Bmw 840i Convertible to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
