The start: 0 to 100 km/h

Off the line, the 911 Turbo S hits 100 km/h in 2.95 s versus 4.83 s for the M440i. At this point, the 911 Turbo S leads by 1.87 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo S is doing 176 km/h against 146 km/h for the M440i. The gap is 1.63 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.57 s versus 12.93 s. The 2.36 s gap represents roughly 114 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Turbo S continues to build its lead. At 600 metres, it runs at 243 km/h versus 205 km/h. At 1,000 metres, the 911 Turbo S finishes in 19.22 s versus 23.15 s, with a 3.93 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Turbo S is capped at 317 km/h, the M440i at 250 (i.e. 155 mph - industry threshold) 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (2.83 kg/hp vs 4.53 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.06 seconds. The 1.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
