Bmw i4 M50 xDrive vs 911 Turbo: chronicle of a drag race at 311 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Turbo hits 100 km/h in 3.53 s versus 3.92 s for the Bmw i4 M50 xDrive. Despite lacking instant torque, 507 hp of power compensates. At this point, the 911 Turbo leads by 0.39 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Turbo is doing 168 km/h against 155 km/h for the Bmw i4 M50 xDrive. The gap is 0.42 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Turbo crosses the line in 11.25 s versus 12.01 s. The 0.76 s gap represents roughly 40 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 233 km/h versus 216 km/h. At 1,000 metres, the 911 Turbo finishes in 20.27 s versus 21.97 s, with a 1.69 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw i4 M50 xDrive is capped at 225 km/h, the 911 Turbo at 312 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 5.72 seconds. The 0.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Turbo is slightly faster than the Bmw i4 M50 xDrive to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
