The start: 0 to 100 km/h

Off the line, the M240i hits 100 km/h in 4.67 s versus 5.75 s for the Model S 85. Despite lacking instant torque, 340 hp of power compensates. At this point, the M240i leads by 1.08 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M240i is doing 147 km/h against 137 km/h for the Model S 85. The gap is 0.82 s. The challenger starts to claw back ground.

At 400 metres standing start, the M240i crosses the line in 12.78 s versus 13.94 s. The 1.16 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 M240i continues to build its lead. At 600 metres, it runs at 205 km/h versus 190 km/h. At 1,000 metres, the M240i finishes in 23.03 s versus 25.17 s, with a 2.13 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Model S 85 is capped at 201 km/h, the M240i 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.

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 8.41 seconds. The 1.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
