Tesla Model X P100D vs Alpine A110 GT 300: which is truly faster?

Off the line, the Model X P100D hits 100 km/h in 3.05 s versus 3.92 s for the A110 GT 300. The instant torque of 967 Nm from the electric motor makes the difference. At this point, the Model X P100D leads by 0.86 s and sits roughly 10 m ahead.

At 200 metres, the Model X P100D is doing 167 km/h against 157 km/h for the A110 GT 300. The gap is 0.76 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model X P100D crosses the line in 10.97 s versus 11.96 s. The 1.00 s gap represents roughly 53 m of track — a gap visible to the naked eye.

Past 400 metres, the Model X P100D continues to build its lead. At 600 metres, it runs at 231 km/h versus 215 km/h. At 1,000 metres, the Model X P100D finishes in 20.13 s versus 21.76 s, with a 1.63 s lead. Despite a higher top speed (272 km/h), the A110 GT 300 never recovers its launch deficit.

Electronically capped at 249 (i.e. 155 mph — industry threshold) km/h, the Model X P100D never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

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 5.79 seconds. The 0.86 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
