The start: 0 to 100 km/h

Off the line, the Model Y Long Range RWD hits 100 km/h in 5.37 s versus 8.51 s for the G9. At this point, the Model Y Long Range RWD leads by 3.14 s and sits roughly 35 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Model Y Long Range RWD is doing 131 km/h against 120 km/h for the G9. The gap is 2.08 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model Y Long Range RWD crosses the line in 13.90 s versus 16.32 s. The 2.41 s gap represents roughly 96 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Model Y Long Range RWD continues to build its lead. At 600 metres, it runs at 172 km/h versus 169 km/h. At 1,000 metres, the Model Y Long Range RWD finishes in 26.20 s versus 28.71 s, with a 2.51 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the G9 is capped at 200 km/h, the Model Y Long Range RWD at 217 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 electric powertrains, the difference comes down to power-to-weight ratio (7.18 kg/hp vs 6.84 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.63 seconds. The 3.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
